====== Signing an Android Application (apk) for Release ======

If needed, create a keystore, as follows:

<code>"%JAVA_HOME%\bin\keytool" -genkey -v -keystore android.keystore -alias android -keyalg RSA -validity 10000</code> 

You'll be asked to enter a password, name, etc.

Sign your apk, as follows:

<code>"%JAVA_HOME%\bin\jarsigner" -verbose -keystore android.keystore MyAndroidApp.apk android</code>


You could easily create a drap/drop batch file to sign & verify applications, using something similar to the following:

<code>
@echo off
"%JAVA_HOME%\bin\jarsigner" -verbose -keystore "%USERPROFILE%\<path_to>\android.keystore" "%1" android
if errorlevel 1 goto ERROR
"%JAVA_HOME%\bin\jarsigner" -verify "%1"
if errorlevel 1 goto ERROR
goto DONE
:ERROR
@pause
:DONE
@echo on
</code>

To install the application on the Android Device Emulator:

  - Run the emulator
  - Open a command/console window in the SDK ''tools'' directory
  - Issue the following command:

  <code>adb install "<path_to>\MyAndroidApp.apk"</code>
