I tried to compile my project with Android Studio but if I compile the app this error appers:
Gradle:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':LehrerOrganizerPro:compileDebug'.
> Compilation failed; see the compiler error output for details.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
What do I have to do so I can compile my apps with Android Studio?
