Android-support-v4 Remove Unused Classes

Bacially, I am trying to shrink my application's .apk down to the smallest size possible. I currently have android-support-v4 jar file imported. My question is this: how do I rem

Solution 1:

ProGuard indeed shrinks the size of applications. It treats application code (src/...) and library code (libs/..., library projects) the same, so you don't need to change the structure of your project. It is especially useful if you are using small parts of large libraries, since it removes the unused parts.

The Android developer guide explains how you can enable ProGuard for release builds. If your application doesn't perform any reflection, the default configuration (with an empty proguard-project.txt) should be sufficient.
