Android app crashes after SDK-tools update version (NoClassDefFound, tool version 22)

Question

I have just updated my android SDK tools to the newly released version (tools version 22, platform tools version 17)

java.lang.NoClassDefFoundError
         


        

Answer 1

I ran into this on Android Studio. Since most of the answers here are for Eclipse, here's how to add the supportv4 library on Android Studio:

1. Build -> Edit Libraries and Dependencies
2. Click the + button
3. Select the support-v4 library
4. Click OK.

That's it.
