Signing and Generating an Android APK

APK is the executable binary file for ANdroid app. It’s like the EXE file for Windows. Before an APK file is distributed in the market (eg - Android Market), you need to sign the apps using the Keytool provided by the JDK.

Keytool is used to generate KeyStore is responsible for maintaining cryptographic keys and their owners This is needed to sign your Android app before publishing to the Android Market (http://developer.android.com/guide/publishing/app-signing.html).

Signing Your apps

Before you begin, make sure that the Keytool utility and Jarsigner utility are available to the SDK build tools. Both of these tools are available in the JDK. In most cases, you can tell the SDK build tools how to find these utilities by setting your JAVA_HOME environment variable so it references a suitable JDK. Alternatively, you can add the JDK version of Keytool and Jarsigner to your PATH variable.

LINUX - If you are developing on a version of Linux that originally came with GNU Compiler for Java, make sure that the system is using the JDK version of Keytool, rather than the gcj version. If Keytool is already in your PATH, it might be pointing to a symlink at /usr/bin/keytool. In this case, check the symlink target to be sure it points to the Keytool in the JDK.

WINDOWS – Locate the keytool application. Normally it’s in the JDK installation folder, bin. For example in my PC it’s in C:\Program Files\Java\jdk1.6.0_29\bin .
