Android NoClassDefError (클래스는 Google지도를 사용합니다.)

이것은 안드로이드에서 Google지도를 처음 사용하는 것이지만,지도를 표시 할 페이지로 이동할 때 NoClassDefError가 표시됩니다.Android NoClassDefError (클래스는 Google지도를 사용합니다.)

나는 이것에 대한 이유를 탐구하고 나는 정상적인 자바 이해하지만 문제를 찾을 수 없습니다.

Google Play 서비스 라이브러리는 내 프로젝트에서 라이브러리로 가져 오기 때문에 Google지도를 찾는데 실패하지 않습니다. (어쨌든 말할 수있는 것에서부터).

나머지 애플리케이션은 정상적으로 작동하지만 오류는이 페이지가로드/탐색 될 때만 발생합니다.

WalkRecording.java

package dcs.aber.ac.uk.cs211.group02; 

import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.SupportMapFragment; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.view.Menu; 

public class WalkRecording extends FragmentActivity { 

    private GoogleMap map; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_walk_recording); 
     map=((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.mapView)).getMap(); 

     map.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.walk_recording, menu); 
     return true; 
    } 



}

이 클래스에 스왑 코드 :

public void addListenerOnButtons(){ 

     recordButton = (Button) findViewById(R.id.createWalkButton); 
     recordButton.setOnClickListener(new OnClickListener(){ 

      @Override 
      public void onClick(View v){ 

       Intent intent = new Intent(context, WalkRecording.class); 
       startActivity(intent); 
      } 

     });

나는 또한 그래서 세대 폴더는 빌드 순서에서 소스 폴더 위에 설정했습니다.
