Answer 1

To create an obfuscated jar file you can do that by adding build.xml file to it and making changes in your proguard-project.txt file and running ant release from command line and you will find the obfuscated.jar under a proguard folder in your bin folder of project

Steps

• To add build.xml in your project in linux:

  open a terminal and go to android/tools/ant folder and run

  ./android update project -p /path_of_your_android_library_project 
  

  and you will find build.xml in your project root directory.

• to enable obfuscation in your project:

  In your editor open a project.properties file and remove comment from

  proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
  

• add your changes to proguard-project.txt file and in terminal go to your project and run

  ant release
