Sto provando a eseguire un semplice test JUNIT per una classe di test in Android Studio. La build va bene. Quando si tenta di eseguire il test JUnit ottengo il seguente erroreAndroid Studio: Eccezione puntatore nullo quando si esegue l'attività gradle assembleDebugUnitTest
*
Execution failed for task ':app:mockableAndroidJar'.
> java.lang.NullPointerException (no error message)
*
Quando ho buttato lo StackTrace ottengo il seguente. Non ho idea del perché questo sta accadendo.
:

Ambiente di test utilizzato:
Ambiente: 1.2.2 SDK Versione: API 21 strumenti di compilazione 22.0.1 versione Plugin Android: 1.2.3 versione Gradle: 2.5 JDK: 1.7. 0_79
Potete per favore aiutarmi con questo? C'è qualche problema con il mio setup?

}
Ho lo stesso problema, penso che ci sia qualche correzione di bug nell'ultimo aggiornamento dell'SDK. Così aggiorno all'ultima versione o al mio SDK 19, tutto funziona. – Happier
