error :

Error:Execution failed for task ‘:app:preDexDebug’.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘C:\Program Files\Java\jdk1.7.0_67\bin\java.exe’ finished with non-zero exit value 1

reason: the configuration in gradle

compileSdkVersion 23
buildToolsVersion ‘24.0.0 rc3’

compileSdkVersion and buildToolsVersion are inconsistent

changes compileSdkVersion as well as buildToolsVersion

compileSdkVersion 23
buildToolsVersion ‘23.0.0’

and then just compile it once.
