NoClassDefFoundError仅适用于API 22

我正在开发一个用于API 23和22的项目，但是，一旦应用程序启动崩溃（活动甚至无法加载），只会发生API 22，API 23它工作正常。 这个日志对我没有太大的帮助，而且我对于可能导致这个错误发生的想法已经不知所措了。 它抱怨的类是清单中定义的App类。 以下是一些可能有助于分析的代码：

表现：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="br.com.gogame"> <application android:name=".commons.infra.App" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:installLocation="preferExternal" android:label="@string/app_name" android:largeHeap="true" android:theme="@style/AppTheme"> <meta-data android:name="DATABASE" android:value="gogame.db" /> <meta-data android:name="VERSION" android:value="27" /> <meta-data android:name="QUERY_LOG" android:value="false" /> <meta-data android:name="DOMAIN_PACKAGE_NAME" android:value="br.com.gogame.model" /> <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> <activity android:name=".view.activities.ActivityLogin" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> 

应用程序类（它所抱怨的那个不存在）：

公共类App扩展com.orm.SugarApp {

 private static App mApp = null; private static MainComponent component; private static RestTemplate mRequestService = new RestTemplate(); @Override public void onCreate() { super.onCreate(); mApp = this; component = DaggerMainComponent .builder() .utilModule(new UtilModule(this)) .postmanModule(new PostmanModule(mRequestService)) .controllerModule(new ControllerModule()) .build(); Intent intent = new Intent(this, EventListener.class); startService(intent); } public static Application getApplication() { return mApp; } public static Context getContext() { if (mApp == null) { return new Application(); } return mApp.getApplicationContext(); } public static MainComponent getComponent() { return component; } public static boolean isApplicationInBackground() { boolean isInBackground = true; ActivityManager am = (ActivityManager) mApp.getApplicationContext().getSystemService(Context.ACTIVITY_SERVICE); if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT_WATCH) { List<ActivityManager.RunningAppProcessInfo> runningProcesses = am.getRunningAppProcesses(); for (ActivityManager.RunningAppProcessInfo processInfo : runningProcesses) { if (processInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) { for (String activeProcess : processInfo.pkgList) { if (activeProcess.equals(mApp.getApplicationContext().getPackageName())) { isInBackground = false; } } } } } else { List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1); ComponentName componentInfo = taskInfo.get(0).topActivity; if (componentInfo.getPackageName().equals(mApp.getApplicationContext().getPackageName())) { isInBackground = false; } } return isInBackground; } 

}

logcat的：

你要踢自己..

在清单软件包名称是缺少br在开始它应该是：br.com.gogame.commons.infra.App

你反而把它作为.com.gogame.commons.infra.App这将无法正常工作，因此类没有发现错误
