After updating to android studio 2.3 I got this error message. I know it\'s just a hint as the app run normally but it\'s really strange.
All com.andr
I had the same problem before and I got the solution for it.
I just added the libraries that had the another version but with the same version of my support:appcompat
.
For your error for example :
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0
*The solution is to compile the versions of these libraries like that :
compile 'com.android.support:mediarouter-v7:25.1.1'
-if another library had the same issue and had another version just compile it with your support:appcompat
version
This resolved my problem and I hope it resolves yours.
Best wishes :)
