I have the same problem, I also set a new adapter on the spinner and is not working.

@pepitofriki I just found a solution, just set your selected position to 0 before clear the adapter.

When I add the .jar and src/\* files I get the next error: Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/spoledge/aacdecoder/AACPlayer.class
