In my previous post, we have seen how to extract the contents of img file . After extraction, you will find that most of the files have ".dex" extension. These are Compiled Android application code files. In order to convert them into executable format (.class or .jar), you can use dex2jar tool. Extract it to a proper location and open the terminal to this location. Now run the following command: ./d2j-dex2jar.sh <Path-to-dex_file> It will bundle the dex files into a jar file, and stores it in the current directory. dex2jar can also be used to convert dex files into variuos other formats.

Today, I tried to install an application from command line and I found this error: Failure [INSTALL_FAILED_UID_CHANGED] After Googling for a while, I found the reason. This happens when there is application data from older version is still present. To resolve this, clear/delete the following directory: /data/data/<PACKAGE_NAME> To do this, open terminal and type the following commands: adb shell cd /data/data/ rm -r <PACKAGE_NAME> exit Now try to install the application. Viola.

Errors on the project build path when using Eclipse When I debug the framework source using Eclipse, there are some errors on the project build path. Error messages I saw are the following : Project 'Android' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/google-common_intermediates/javalib.jar' Project 'Android' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/gsf-client_intermediates/javalib.jar' Solution: Goto Project>Properties and libraries section and edit first one to "out/target/common/obj/JAVA_LIBRARIES/android-common_intermediates/javalib.jar"  and remove second one. Missing required library when import the android source 4.0 to Eclipse After this, the build path errors were gone, but I got about 200 errors referring to missing types. This could only be another classpath problem for Eclipse. Here are the extra libraries, that we have to add to the .classpath file: <c...

After you finish configuring your application you can build it into a release-ready .apk fle that is signed and optimized. The JDK includes the tools for signing the .apk file (Keytool and Jarsigner); the Android SDK includes the tools for compiling and optimizing the .apk file. If you are using Eclipse with the ADT plugin or you are using the Ant build script from the command line, you can automate the entire build process. In preparation for signing your application, you must first ensure that you have a suitable private key with which to sign. Following Keytool command generates a private key: $ keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000 Running the example command above, Keytool prompts you to provide passwords for the keystore and key, and to provide the Distinguished Name fields for your key. It then generates the keystore as a file called  my-release-key.keystore . The keystore and key are protec...

First you need to get ready with the phonegap running properly. It's here . First download the source from here Now follow these procedure:  1.
