I have a problem with Android Studio 0.2.3.
When I run my project the build stops and appears message that says:
Gradle: Execution failed for task ':AppName:compileDebugAidl'.
> failed to find target android-18
I think you might not have the Android-18 sdk installed. Go to Tools > Android > SDK Manager and check to see if Android 4.3 (API 18) is installed.
