Besetzung mit Multidexing

Question

Ich versuche AndroidTest aber ich bekam die folgende Fehlermeldung auszuführen:

:app:transformClassesWithMultidexlistForDebugAndroidTest 
ProGuard, version 5.2.1 
Reading program jar [app/build/intermediates/transforms/jarMerging/androidTest/debug/jars/1/1f/combined.jar]

:app:transformClassesWithDexForDebugAndroidTest 
Error:Error converting bytecode to dex: 
Cause: Dex cannot parse version 52 byte code. 
This is caused by library dependencies that have been compiled using Java 8 or above. 
If you are using the 'java' gradle plugin in a library submodule add 
targetCompatibility = '1.7' 
sourceCompatibility = '1.7' 
to that submodule's build.gradle file. 
Error:1 error; aborting 
Error:Execution failed for task ':app:transformClassesWithDexForDebugAndroidTest'.

Manchmal läuft es und manchmal zeigen sie gerade diesen Fehler oder diesen Fehler:

The APK file /bb/app/build/outputs/apk/app-debug-androidTest-unaligned.apk does not exist on disk. Error while Installing APK 

Dies ist mein build.gradle:

und das ist mein Läufer:

public class MyTestRunner extends AndroidJUnitRunner { 
@Override 
public void onCreate(Bundle arguments) { 
    MultiDex.install(this.getTargetContext()); 
    super.onCreate(arguments); 
} 

und dies ist mein Test:

@LargeTest 
public class DatabaseRepositoryInstrumentationTest extends InstrumentationTestCase { 
    public static final String TAG = DatabaseRepositoryInstrumentationTest.class.getSimpleName(); 
    DatabaseRepository db; 
    Handler handler; 
    RealmConfiguration realmConfiguration; 

    @Before 
    public void setUp() throws Exception { 
     Context context = InstrumentationRegistry.getTargetContext(); 
     db = new DatabaseRepositoryImpl(context); 
     assertNotNull(db); 
     handler = new Handler(Looper.getMainLooper()); 
     realmConfiguration = new RealmConfiguration.Builder(context) 
       .name("test.realm") 
       .build(); 
     Realm.deleteRealm(realmConfiguration); 
     Realm.setDefaultConfiguration(realmConfiguration); 
    } 

    @Test 
    public void saveAndLoadDataMaster() { 
     //to avoid java.lang.IllegalStateException: Your Realm is opened from a thread without a Looper. Async queries need a Handler to send results of your query 
     handler.post(new Runnable() { 
      @Override 
      public void run() { 
       try { 
        db.saveDataMaster("masterdata.json"); 
       } catch (IOException e) { 
        fail(e.getMessage()); 
        Log.d(TAG, "Error in saving data to Realm!"); 
       } 
       Observable<RealmResults<DataMaster>> dataObservable = db.loadDataMaster(); 
       dataObservable.subscribe(new Subscriber<RealmResults<DataMaster>>() { 
        @Override 
        public void onCompleted() { 
         db.close(); 
        } 

        @Override 
        public void onError(Throwable e) { 
         Log.d(TAG, "Could not load master data!"); 
         fail(e.getMessage()); 
         db.close(); 
        } 

        @Override 
        public void onNext(RealmResults<DataMaster> dataMasters) { 
         DataMaster dataMaster = dataMasters.first(); 
         Log.d(TAG, "db version" + dataMaster.getVersion()); 
         Log.d(TAG, "call: " + dataMaster.getEquipments().first().getMeasurands().first().getName()); 
         Log.d(TAG, "call: " + dataMaster.getEquipments().first().getMeasurands().first().getUiPrimary()); 
         Log.d(TAG, "call: " + dataMaster.getEquipments().first().getMeasurands().first().getUiSecondary()); 

         Log.d(TAG, "call: " + dataMaster.getEquipments().first().getMeasurands().first().getDecimalPoint()); 

         assertThat("13062016-2", is(equalTo(dataMaster.getVersion()))); 
        } 
       }); 
      } 
     }); 
    } 
} 

Irgendwelche Hinweise oder Vorschläge in dem, was ich tue, falsch ist völlig geschätzt.

Ich habe versucht, Ihr Problem mit dem bereitgestellten Code zu reproduzieren, war aber nicht erfolgreich. Können Sie ein Beispielprojekt an help@realm.io weitergeben, damit wir Sie unterstützen können?

S.S> Ich glaube, Sie haben AndroidManifest.xml für Multidex auch konfiguriert.

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.android.multidex.myapplication"> 
    <application 
     ... 
     android:name="android.support.multidex.MultiDexApplication"> 
     ... 
    </application> 
</manifest>
