Google Map Directions in android

Question

Ich versuche, Google Map Richtung auf mein Projekt verwenden

hier genannt: http://www.akexorcist.com/2015/12/google-direction-library-for-android-en.html

aber es gibt mir diese Fehler -> Die Anzahl der Verfahren Referenzen in einer .dex Datei überschreiten, können nicht 64K

Dieser Fehler tritt auf, da die Anwendung die Grenze von 65k Methode kreuzt. Um dieses Problem zu lösen, müssen Sie die Multidex-Unterstützung aktivieren. Erstellen Sie eine Anwendungsklasse wie folgt und registrieren Sie sie in der Datei "manifest.xml" unter dem Anwendungs-Tag.

public class YouApplication extends Application { 

    @Override 
    protected void attachBaseContext(Context base) { 
     super.attachBaseContext(base); 
     MultiDex.install(this); 
    } 

} 

Aktualisieren Sie Ihre build.gradle Datei

android { 
     compileSdkVersion 22 
     buildToolsVersion "23.0.0" 

      defaultConfig { 
       minSdkVersion 14 //lower than 14 doesn't support multidex 
       targetSdkVersion 22 

       // Enabling multidex support. 
       multiDexEnabled true 
      } 
    } 

    dependencies { 
     compile 'com.android.support:multidex:1.0.1' 
    }
