Compile with Android Proguard error: can't find references?

I tried exporting my code to .apk file with Proguard but get a lot of warnings. I tried many solutions but can't fix it. Any ideas?

The support classes refer to run-time classes and methods that are not necessarily present in all Android versions. They do handle this in a safe way: the code works in all Android versions -- that's their purpose. You can therefore tell ProGuard to ignore the issues, in the configuration file proguard-project.txt:

-dontwarn android.support.**
