在Android 4.4中运行时应用程序崩溃（NoClassDefFoundError）

Question

应用程序在Android 4.4中运行并显示NoClassDefFoundError时崩溃。但在其他Android版本中正确工作到6.0。我在这里使用片段活动。错误如下所示。

public class MainActivity extends Activity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 

     setContentView(R.layout.activity_main); 
     if (savedInstanceState == null) { 
      FragmentManager fragmentManager = getFragmentManager(); 
      FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 
      LoginPatternFragment loginFragement = new LoginPatternFragment(); 
      fragmentTransaction.add(R.id.fragement, loginFragement); 
      fragmentTransaction.commit(); 
     } 
    } 

错误：

E/memtrack: Couldn't load memtrack module (No such file or directory) 
    E/android.os.Debug: failed to load memtrack module: -2 
    E/dalvikvm: Could not find class 'com.quicknip.restaurant3.Fragment.LoginPatternFragment$13', referenced from method com.quicknip.restaurant3.Fragment.LoginPatternFragment.loginService

Answer 1

最后我找到答案。

通过更换

compile 'com.google.android.gms:play-services:8.4.0' 

到

compile 'com.google.android.gms:play-services-analytics:8.4.0' 
compile 'com.google.android.gms:play-services-gcm:8.4.0' 
compile 'com.google.android.gms:play-services-location:8.4.0' 
compile 'com.google.android.gms:play-services-plus:8.4.0' 

这对我的作品。

Answer 2

创建一类像这样

class MyApplication extends Application { 

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

在你AndroidManifest，添加name属性到应用程序标签：

<application name=".MyApplication"
