java.lang.ClassNotFoundException in AsyncTask auf API 16 bis 19

Question

Ich habe einen Fehler, der nur in Android 4 (API 16 bis 19) passiert.

Ich verwende den folgenden Code

private class AcceptBooking extends AsyncTask<String, Void, String> { 
    int response; 

    @Override 
    protected void onPreExecute() { 
    } 

    @Override 
    protected void onPostExecute(String s) { 
     switch (response){ 
      case NO_UPDATE: 
       startApp(); 
       break; 
      case SUGEST_UPDATE: 
       adviceUpdate(); 
       break; 
      case FORCE_UPDATE: 
       forceUpdate(); 
       break; 
      default: 
       startApp(); 
       break; 
     } 

    } 

    @Override 
    protected String doInBackground(String... params) { 
     response = DBConnect.updateApp(); 

     return "done"; 
    } 
} 

Und wenn ich versuche, dieses AsyncTask ich folgende Fehlermeldung erhalten, auszuführen:

com.socialcar E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #2

    at java.lang.Thread.run(Thread.java:856) 

Und das ist es, die Abhängigkeiten, die ich in gradle haben:

compile fileTree(include: ['*.jar'], dir: 'libs') 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.2.0' 
    compile 'com.android.support:design:23.2.0' 
    compile 'com.facebook.android:facebook-android-sdk:[4,5)' 
    compile 'com.google.android.gms:play-services:7.8.0' 
    compile 'org.apache.httpcomponents:httpmime:4.2.3' 
    compile 'com.google.guava:guava-jdk5:17.0' 
    compile 'com.android.support:multidex:1.0.1' 
    compile 'com.mcxiaoke.volley:library-aar:1.0.0' 
    compile 'de.hdodenhof:circleimageview:2.0.0' 
    compile 'com.android.support:cardview-v7:23.0.+' 
    compile 'com.android.support:recyclerview-v7:23.0.+' 

Ich versuche in diesem und anderen Foren eine Lösung zu finden und anscheinend das com.android.suppo rt: appcompat-v7-Version kann das Problem sein, aber Änderungen, die nicht funktionieren. Und auch ich java.util.objects wird in Java 7 eingeführt und das kann auch Auswirkungen haben, aber ich bin mir nicht sicher, was zu tun ist, um das zu beheben.

Jede andere Idee wird willkommen sein.

Hier ist die BDConnect Klasse, der den Fehler geben:

Answer 1

Fügen Sie diese Zeile in build.gradle:

compile 'com.android.support:multidex:1.0.1'

nun in der Anwendung Tag in Ihrem Mainfest diese Zeile hinzufügen,

android:name="android.support.multidex.MultiDexApplication"

Dann die folgende Klasse erstellen:

public class MultiDexApplication extends Application { 
public MultiDexApplication() { } 
    protected void attachBaseContext(Context base) { super.attachBaseContext(base); 
MultiDex.install(this); 
} 
    }
