see this. I also came across this problem, the way to solve it is as follows: first disable the "InstantRun" function, then click "Invalidate Cache/Restart" in "File" Menu, uninstall the apk in phone or emulator is ok before rebuilding it. Then there are no errors like that. In fact, these errors don't make any difference to the apk.

You have this issue because you are trying to method that is available only from API level 21.The issue is because of Change to compileSdkVersion 22 & update the build.gradle to compile 'com.android.support:appcompat-v7:22.0.0'
