在 android 4.4 中运行时应用程序崩溃并显示 NoClassDefFoundError。但在 6.0 以下的其他 Android 版本中可以正常工作。我在这里使用 fragment Activity 。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

最佳答案
创建一个这样的类
class MyApplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
在 AndroidManifest 中，向应用程序标记添加 name 属性:
<application name=".MyApplication"
