Proguard

If you’re obfuscating your Android applications using ProGuard, make sure to keep the proguard/ directory at the root of your Android project under revision control. This may seem contrary to what you’d feel like doing, as the files are autogenerated, but it will help if you ever need to debug a stack trace from your published application. Typically when I’m ready to release, and after I’ve done every other change, I will bump the revision in my AndroidManifest.xml and generate a new .apk from eclipse, then test it out on my device. »
