JDK Download and Install, with Windows Environment Variables

1. DOWNLOAD: Java JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html
   Previous Android releases may be based on earlier Java resleases. So to avoid errors in Android SDK loading, instead use
   Previous Releases > Java SE 6 > Java Archive
   Scroll down to the latest JDK 6 download.
2. TIP: Run a command window, cd \, and dir /x to identify the ", "/X-rated" short name of folder Program Files. It's usually PROGRA~1 for Program Files and PROGRA~2 for Program Files (x86)

   This is to create a folder path which doesn't have spaces, to avoid issues by Java utilities such as Eclipse.

3. From Windows Start, right-click on Computer > Advanced > Environment Variables.
   • Add to the System PATH Windows Environment Variable
     C:\PROGRA~1\Java\jdk1.6.0_31\bin

     TIP: Put this at the front of the PATH for slightly faster performance.

   • Add to the System JAVA_HOME Windows Environment Variable :
     C:\PROGRA~1\Java\jdk1.6.0_31

4. TEST: Verify that Java is available. In Windows Start > Run... > cmd, OK, type:
   java -version

   The expected reply looks something like this:

   java version "1.6.0_31"
   Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
   Java HotSpot(TM) 64-bit Server VM (build 20.6-b11, mixed mode)
   

Android SDK Download and Install

1. DOWNLOAD: Android SDK from http://developer.android.com/sdk.
2. DOWNLOAD: adb.exe for use by Windows 7 into the android-sdk /tools folder.
3. TEST TIP: Verify the MD5 checksum. It's difficult to trace problems to a corrupted installer file. So just take a minute and check.
4. Before running the exe, go into Task Manager, Processes. If adb.exe is active, end the process. If fact, close all other windows because a reboot will be necessary.
5. Invoke the SDK installer.
   TIP: Change the default install path from
   C:\Program Files (x86)\android-sdk on a 64-bit machine or
   C:\Program Files\Android\android-sdk to a path that's shorter and doesn't contain spaces like
   C:\android-sdk

   The alternative is to install in program files but reference it using short names such as PROGRA~1 or PROGRA~2.

   This is to avoid issues by Java utilities such as
   TOOL: ProGuard code obscusator.

6. Specify Windows Environment Variable ANDROID_SDK_DIR to the SDK:
   C:\android-sdk
7. Specify both Windows Environment Variables ANDROID_SDK_HOME and HOMEPATH to wherever .android\avd files are.

   You can specify %USERPROFILE% for the location Windows creates for the current user logged in:
   C:\users\myusername

   TIP: I like to keep all Android-related files (installers, tutorials, software, etc.) together under a single folder so I can move them without forgetting about files in my personal folder. Since no one else uses my files, I specify:
   C:/ref/Android/.android

8. When the SDK Manager opens, check Select all (SDK versions, Extras, etc.).
9. Uncheck default activation of the SDK Manager.exe, which remains as a blank black screen because it is a background process running. This is better done later from inside Eclipse.

   TIP: Download all source files. During Android development it is often useful to have the Android source code available to see undocumented defaults.
   EXCLUSIVE: Example Source

10. Before clicking Close, note:
    • Ignore message "Stopping ADB server failed (code -1)." because it was not running anyway.
    • Android SDK release 12 is named like installer_r12-windows.exe for http://developer.android.com/guide/appendix/api-levels.html The r12 executable has a bug. Click Back if it doesn't recognize the Java installation.
11. When complete, restart Windows to avoid memory issues during the next steps that run a long time.
12. TEST: TIP: In Windows Explorer, right-click on the folder to get properties to make sure you haven't been short-changed.

    Expanded,
    v13 contains 46,790 files in 6,666 folders taking 1.8 GB.
    v15 contains 45,797 files in 7,185 folders taking 2.58 GB.

13. Recover disk space by archiving or otherwise deleting the SDK installer exe file.
14. To enable SDK tools on a PC, in Windows Environment Variables, add to the end of system PATH the folders where the SDK was installed. For example
    ;C:\android-sdk\tools;C:\android-sdk\platform-tools;

MotoDev

TOOL: MOTODEV Studio for Android [@motodev] is useful for all Android devices, not just Motorola's. It provides tools for SQLLite browsing, Translation, Debugging, etc.

If you prefer using the Eclipse plug-in version rather than the full gui, from Eclipse's Help menu, select Install New Software for the Available Software dialog. Click Add (to the right of the Work with field) for the Add Site dialog. download the zip file (Archive) or https://studio-android.motodevupdate.com/android/3.0

After Eclipse restarts, MOTODEV should appear in the menu bar.

Read their Release Notes fully for known issues.

TEST: To scan apps for compatibility with Motorola smartphones and tablets, from Windows Explorer drag and drop apk files to Windows desktop program
TOOL: MotoDev App Validator, whose SDK enable it to be customized.

Other IDEs

TOOL: JetBrains IntelliJ IDEA Community Edition (Be sure to include Android option when installing)

Oracle Sun NetBeans

Oracle JDeveloper

I have not messed with

Eclipse IDE and ADT Plug-ins Installation

Getting Started Using Eclipse
is thorough and sequenced well.
A great tutorial.

Top 10 Tips for New Eclipse Users

Eclipse version names:
3.8.x (Juno)
3.7.x (Indigo)
3.6.x (Helios)
3.5.x (Galileo)
3.4.x (Ganymede)
3.3.x (Europa)
3.2.x (Callisto)

DOWNLOAD: TOOL: Eclipse from Eclipse.org. Choose
Eclipse IDE for Java EE Developers Windows 32-bit.
TIP: Most developers still prefer the 32-bit version to avoid past issues with 64-bit.

In the zip file like eclipse-jee-juno-win32.zip is an eclipse folder.
TIP: Some expand this folder within folder C:\bin because Eclipse is not a Windows program.

REMINDER: The default workspace on Windows is C:\Users\%USERNAME%\workspace
TIP: I prefer to keep all files together in folder C:\ref\Android\workspace.

To change the workspace after installation, in Eclipse change File > Workspace > Other.
Or close Eclipse and in folder %ECLIPSE_HOME%\configuration\.settings edit the org.eclipse.ui.ide.prefs file to change the value to RECENT_WORKSPACES. To be prompted to select the workspace when you start Eclipse, change the value to SHOW_WORKSPACE_SELECTION_DIALOG to true.

The first time in Eclipse Help > Install New Software > Work with: https://dl-ssl.google.com/android/eclipse/ to Add repository named Android. Select all the Developer Tools DDMS (Dalvik Debug Monitor Server) perspective, Development Tools, Hierarchy Viewer, Traceview. Accept the license and unsigned warning. Restart Eclipse.

Once installed, obtain updates in Help > Update.

What is ADT (Android Development Tools)

ADT Download site

ADT ChangeLog

ADT is a development plugin for the Eclipse IDE It extends the capabilites of Eclipse to
• generate new Android projects (from File > New > Other > Android > Android Project),
• create an application UI,
• add components based on the Android Framework API,
• debug applications using Android SDK tools, and
• export signed (or unsigned) APKs for distribution as apps

ADT 16.0.0 was written for installation on Eclipse Helios (Version 3.6) or higher for use with SDK Tools r16, which added
Lint static analysis tool which looks for bugs (common errors) in Android project Java code.

Eclipse Add-ins Installation

A). If you want to:

• Add API Analysis plugin to stop annoying false warnings about using high-level API and a lower minSdkVersion than the targetSdkVersion.
• enhance refactoring (rename) of Android code
• add Eclipse cheatsheets
• pack Android sources

Do the following:

1. In Eclipse menu Help > Install New Software... > Add,
2. Into the Work within the resulting pop-up, paste this URL:

   http://adt-addons.googlecode.com/svn/trunk/source/com.android.ide.eclipse.source.update/

3. Click Add.
4. In the next pop-up, for Name: adt-addon
5. Click OK.
6. Check the Android Sources checkbox.
7. Click "Next" for Eclipse to calculate requirements.
8. Click Next for Install Details.
9. Click "I accept", then "Finish".
10. Wait for "Installing Software" to conclude.
11. Restart Eclipse.

B). If you want to search within source code:

1. In Eclipse menu Help > Install New Software... > Add,
2. For Location, paste this URL:

   http://repository.grepcode.com/java/ext-eclipse/

3. Into the resulting pop-up, for Name: Grepcode
4. Click OK.
5. Click Next in the Install Details page.
6. Check the box in front of Grep Search. Lower-level check boxes should be checked.
7. Click Next twice.
8. Accept the license and click on the "Finish" button in the license page.
9. Click OK to the signing Security Warning.
10. Restart Eclipse.

Java Decompiler

C). If you want to run a Java Decompiler (from class files in a jar):
1. In Eclipse menu Help > Install New Software... > Add,
2. For Location, paste this URL:

   http://java.decompiler.free.fr/jd-eclipse/update

3. Into the resulting pop-up, for Name: JD-Eclipse Update Site
4. Click OK.
5. Click Next in the Install Details page.
6. Check the box in front of Java Decompiler Eclipse Plug-in. Lower-level check boxes should also be checked.
7. Click Next twice.
8. Accept the license and click on the "Finish" button in the license page.
9. If a certificate verification screen appears, check it and click OK.
10. Wait for the conclusion, then click "Restart Now" to restart Eclipse.

Eclipse Startup

TIP: In the workspace folder, create a Windows shortcut to invoke Eclipse so that it is started with additional parameters. As with all Sun JVMs, by default only 384 MB is allocated and 64 MB to perm. With additional plug-ins, this may not be enough. So to ensure enough memory I right-click the shortcut for the Properties windows to add these settings :

C:\bin\eclipse\eclipse.exe -vmargs -Xmx1024M -XX:MaxPermSize=128m -vm C:\PROGRA~1\Java\jdk1.6.0_25\bin

To prevent java compile errors while resolving import of java.util.TimeZone and other such libraries, the -vm argument defines use of the JDK's JRE rather than the one that comes with Eclipse. Alternately, in Eclipse Window > Preferences -> Java -> Installed JREs > Add... > Standard VM > Next Select "Standard VM", Directory, Add JRE > where the JDK is installed on your system. Other fields will be populated for you after you locate the home directory. Finish. OK. Set the JRE associated with the JDK as the default by checking its box.

New Project in Eclipse Navigator

In Eclipse menu File > New > Other > Android > Android Project.

The projec type "Android Project" was added when (Application Development Tookit) for Eclipse was installed

In the Name field, packages use revserse notation in the format com.company.product.package.

Specify a project name such as "HelloWorld" and select a Android version Target name such as Android 1.6.

An alternative is to open a Windows Run command window and invoke an android.bat command such as:

android create project –t 1 –p HelloWorld –k org.test –a HelloWorld

Arguments:

- n : Project name (optional)
- t : Target ID of the new project (required)
- p : Project directory (required)
- k : Package name for the application (required)
- a : Name of the default Activity (required)

Open Project in Eclipse Navigator

BLAH: Unlike files such as *.doc and *.xls which when clicked invokes the appropriate program,
Eclipse files are not recognized by Windows.

BLAH: Eclipse Window > Show View > Navigator only displays folders which contain a .project file in the root (same folder as the AndroidManifest.xml file).

WARNING: Do not open individual files in Eclipse. First get projects to display in the Navigator, then files within projects will appear.
The "Open project" option in Eclipse is for opening a project still visible in the project explorer area but has been closed by Eclipse. This is confusing to Windows users.

WARNING: To avoid error messages, do not manually copy sample Android project code folders into your Eclipse workspace folder.

1. In Windows Explorer, navigate into the source folder (so you see its AndroidManifest.xml), such as



You may want to use another folder such as C:\Users\%USERNAME%\My Documents\Orubase\Projects\

2. Whether there is an existing .project file in the folder or not, you'll need the path either way.
3. Click to the right of the project name on the gray Windows Explorer file path so the backgound turns white and the path is highlighted.

4. Press Ctrl_C to copy the path to your Windows clipboard.

5. If not already active, invoke Eclipse.
6a. If a .project folder DOES NOT have a .project file already:

1. Press Alt+Shift+N or select Eclipse File > New
2. Press Ctrl+N or select Other...
3. Select Android > Android Project .
4. Check "Create project from existing source".
5. Double-click on the default value in the Location: field to establish focus.
6. Press Ctrl_V to paste the path from the clipboard.
7. If the Finish button is not activated, click the Browse button. The Project Name should now be automatically populated.
   Do not check "Add project to working sets".
8. Click Finish. This causes .project file and .classpath files to be automatically created in the folder.
   The project should now appear in the Eclipse Navigator pane.

6b. If a .project folder HAS a .project file already:

6b.1. Select Eclipse File > Import... > General.
6b.2. Select Existing Projects into Workspace. Next.
6b.3. Click inside the Select root directory: field to establish focus.
6b.4. Press Ctrl_V to paste the path from the clipboard.
6b.5. Click Browse so the Project appears in the list and Finish button appears. If the project does not appear,
a .project file has NOT been created for the project. So Cancel, then open the project as new.
6b.6. Click Copy to workspace.
6b.7. Click Finish. The project should appear in the Eclipse Navigator pane.

WARNING: Watch for errors in the Console and red icons in the Navigator window.

Project Troubleshooting in Eclipse

It is very common to see Console message such as:

• Unable to resolve target 'android-9' or
• default.properties file is missing.

These messages occur because there common agreement Android API level among different files:

• The app's AndroidManifest.xml file
  <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14" />
• The app's project.properties file, such as:
  # Project target.
  target=android-16
• The app's default.properties file, such as:
  # Project target.
  target=android-8
• Whether in Eclipse the AVD for the Android version API specified is available for use.

WARNING: When changing API version, some programming changes in the application source may be necessary.

If there are red icons to the side of the project name, determine the target

1. Right click on the project, then select Properties (or press Alt+Enter).


2. Check the appropriate Android Target and API, then OK.


3. Again right-click on the Project name select from the context menu Android Tools > Fix Project Properties.
4. Select menu Run > Run Configurations...
5. Under Android Appication select the project name.
6. Click Target tab.
7. Check the AVD appropriate for the app.
8. Click Apply and Close.

With the project selected, select from the grey menu bar Project > Properties.
The Java Build Path should show the Android version selected earlier and
com.android.ide.eclipse.adt.LIBRARIES.

WARNING: Do not check "is Library" or you'll get this message when you try to run:

Could not find yourappname.apk!
com.java.Object can't be found
check the build path. Clicking Properties -> Java Build Path -> Libraries, the message
'Unable to get system library for the project'

If there is an AndroidManifest.out.xml, right-click on it and select Delete.
This was created if Run was selected when the AndroidManifest.xml was on the right pane (an Eclipse bug).
Remember to clear off all xml files before attempting a Run.

Android Source Code Files and Folders

Different directories separate files of different format and function.

Files in directory assets are accessed via the AssetsManager GUI and method getAssets().

In the bin folder is the yourActivity.apk file compiled for installation onto devices. Debug versions yourapp-debug-aligned.apk files were optimized with the zipalign utility to make it run faster.

/bin/yourapp.ap_ contains resources packaged in zip format. These files are compiled from source files in the src and folder. The .dex file in the .apk file is also in the folder.

Source files make reference resource names in the R.java file within the gen folder path for the app. This file is automatically generated based on real files physically stored within the res folder.

Each resource created in the "res" folder are automatically defined in "R.java" (within the gen folder) to access it.

Source Version Controls - for OpenIntents

Google's Android Issues List

OpenIntents Google Group
OpenIntents Downloads
OpenIntents Screencasts
Setup on Linux
Setup on Windows

TIP: Checking project code in and out of a code repository (such as SVN or Git) so you can fall back to previous versions of each project. To avoid errors with Eclipse, right click and get properties of the project. In the java build path > order and export tab, select the Android API and OK it.

To work with the OpenIntents library, one is forced to install SVN to download the file specified in the default.properties file specifying dependencies:

android.library.reference.1=../../distribution/DistributionLibrary/

# Project target.

target=android-8

Based on the above, be sure to download and expand the distribution library, then target Andoid API 8.

Getting Started with OI in Eclipse says that SVN is used for downloading the entire WEBSITE: Android OpenIntents library

1. Download and install WinSVN server from among options at http://subversion.apache.org

   The installer should add to the end of System Environment Variable PATH the file path where svn. exe is located:

   C:\PROGRA~1\Subversion\bin

2. Verify that svn can be invoked. Start > Run > cmd > svn. Installation is successful when this appears:
   Type 'svn help' for usage.

3. If you will be using Windows Explorer, also download and install TortoiseSVN from http://tortoisesvn.net/downloads.html and/or
   
4. Download and install the Subclipse plugin for the version of Eclipse you are using, such as site-1.8.4.zip for Eclipse 3.7.

5. Also download the accompanying .md5 file and verify the file.

6. Open a Run command window to issue:

   svn checkout http://openintents.googlecode.com/svn/trunk/ openintents
   

   A lot of files should scroll by.

   TIP: Downloading from the trunk ensures that library projects are included as well.
   Downloading zip files requires manual work to unzip them.

OpenIntents apps. include OI Color Picker, Calendar Picker, Counter, Barcode, Crypto, ShoppingList, RegistryCloud
Historify event aggregator,
Sensor Simulator, etc.

Editing Source in Eclipse with Keyboard Shortcuts

Shortcut Keys for Eclipse

On Macs, replace Ctrl with the Apple key.

To remove Block comment, press Shift + Ctrl +.
To Toggle Comment, press Shift + Ctrl + C.
To Generate Element Comment, press Shift + Alt + J.

For definitions on something highlighted by the mouse, hold down Ctrl .
So highlight a string, use Refactor > Android > Extract Android String to replace what is highlighted with a localizable string reference using method getString(R.string.yourString)); containing reference id "R.string.yourString" you specify.

press Ctrl+Shift+R in Eclipse to find and open its resource definition.

If an Eclipse Project is set by default,
press Ctrl+S to save, which automatically rebuild.

Un-Building APK

The file extension Google uses for Android applications (*.apk ) is a .zip file inside.

1. Change the extension of application file extension apk to zip. Click Yes to the pop-up warning "If you change a file name extension, the file may become ususable.
   Are you sure you want to change it?"
2. If you have not already, install
   TOOL: WinRar for 32-bit and 64-bit (pick one).

   When running the WinRAR Setup, be sure to check JAR so Windows associates the file extension with WinRar.

3. In Windows Explorer, invoke the application zip file using WinRAR.
4. Inside the unzipped folder, the file named classes.dex contains all the java files, in encrypted form. To unencrypt it, install:
   TOOL: Dex2Jar zip file.

   Unzip classes.dex to a folder like C:\ref\android\dex2jar-0.0.9.6 (among your other android files).

5. Copy classes.dex to the folder where you unzipped Dex2Jar.

6. From Windows Start > Run > command line:

   cd \
   cd C:\ref\android\dex2jar-0.0.9.6
   dex2jar.bat classes.dex
   

   exit the command window if you see this expected response:

   dex2jar version: reader-1.7, translator-0.0.9.6, ir-1.4
   dex2jar classes.dex -> classes_dex2jar.jar
   Done.
   

7. If WinRAR is installed, in Windows Explorer, double click on it to unpack classes_dex2jar.jar to a folder, near the apk file

   Drill down from com or org thru the organization, package, etc. until you reach class files.

   REMINDER: Classes with $ in their names are sub-classes.

   To read class files, you need to de-compile them.

De-Compile Complied Class Files

http://code.google.com/p/android-apktool/

In Eclipse menu File > Open a class file, and notice that it's jumbled because it is compiled output.

To de-compile class files to human-developer-readable java source code:

1. DOWNLOAD TOOL: JAD decompiler used by JadClipse. For Windows, it's file Jad 1.5.8g.win.zip (238600 bytes). This was originally developed in 2001 by Pavel Kouznetsov (jad@kpdus.com), which no longer has content.
2. Unzip the jad.exe into a folder that's in your Windows PATH. I created a C:\bin folder for such command-line programs.
3. Rename the readme.txt to jad.readme.txt so the files stay together.
4. DOWNLOAD TOOL: JadClipse plug-in for Eclipse at http://sourceforge.net/projects/jadclipse/ file net.sf.jadclipse_3.3.0.jar.into the eclipse\plugsins folder.

   NOTE: An alternative is JD-Eclipse Java decompiler JD plug-in for Eclipse.

5. For Eclipse to recognize the new plugin, close and start it again.
6. In Eclipse menu Window > Preferences > Java > JadClipse,
   specify the full file path where jad.exe is located. Click OK.
   

   There are also Debug, Directives, Formatting, and Misc. which organize settings described in jad's readme.txt.

7. If now within Eclipse menu File > Open you open a class file, you will see this error:
   Could not open the editor: The Class File Viewer cannot handle the given input ('org.eclipse.ui.ide.FileStoreEditorInput').

   Go into Eclipse menu Window > Preferences > expand General > expand Editors > File Associations, click .class, click Class File Editor (default), click Default button.

   • Add the classes_dex2jar.jar file to a folder above or different than the target app.
   • In Eclipse, right click on the target java project name to select Build path > Configure build path > Libraries tab.
   • Click Add JARs... and find the jar file with the class files you want to decompile After the jar file is in the build path, you will see "referenced libraries" in your eclipse project, expand that and you see the jar file you just added, expand that and you see all the class files contained in the .jar file.
   • Double-click one of the class files and now JD-Eclipse should decompile the .class file

     WARNING: .class files can only be decompiled when inside a .jar file and that .jar file has been added to the Build Path.

   • In Eclipse, try F3 into any class which does not has the source, and Jad will decompile it automatically.

Crittercism for User Messaging, Crash Reports, Diagnostics

TOOL: Crittercism.com

• Crittercism.com founder Andrew Levy at Building43
• Download the library (with or without the in-app user support forum.
Getting Started on Android

Calls to the Crittercism server are made asynchronously.

Amazon Packaging

A separate APK file needs to be created for the Amazon store so that the compliments button in Amazon's feedback springboard directs to the default marketplace for the device. Thus this is neded for Amazon to approve apps.

The apk file to be uploaded to the Amazon Appstore should include this API call, while the other apk file should not.

boolean shouldUseAmazonMarket = true; 
Crittercism.setShouldUseAmazonMarket(shouldUseAmazonMarket); 

Building APK

Each apk file is built by combining its classes.dex file with associated resources.

The Android Asset Packaging Tool (aapt) creates .apk files containing binaries and resources of Android applications.

In Motodev right click project name and select Export/ Android/Export Android Application.

This building can also be done from this command line command in the project's folder:

ant install
or
ant debug

In the package's bin folder, the package created contains an apk file for the app which is installed onto devices.

BlackBerry Builds

To use the run-time on Blackberry PlayBook tablets, Android 2.3.3 applications must be repackaged to BAR file format using:
TOOL: Online packager or
TOOL: Blackberry's Eclipse Plug-in repackaging tool or

These check for compatibility, repackage, debug, and run apps on the BlackBerry PlayBook or BlackBerry Tablet Simulator. It signs apps. Alternately, use the plug-in to create and install a debug token on the BlackBerry PlayBook.

Keyboards and trackball on Blackberry phones can be recognized on tablets Bridge.

PKI ActivClient like DoD's CAC.

Compilation, Packaging and Deployment to Device

Packaging an APK file combines the Dalvik executable with its resources.

Using Studio for Android, select the project, default location and sign the application.

Each APK is signed.

The debug key is used during development.

Each market has its own policy about using real keys published.

The Dex compiler "dx"

If you build apps outside Eclipse, or if you want to build a release version using the ant build scripts, you need at least version 1.8 of Ant from http://ant.apache.org/bindownload.cgi

Ant to compile and build your Android project into an installable .apk file.

keytool from Android SDK tools is used to generate a keystore holding private key certificates
