NoClassDefFoundError仅适用于API 22-Java 学习之路

我正在开发一个曾经适用于API 23和22的项目，但是，一旦应用程序启动它就会发生崩溃（活动甚至无法加载） - 仅适用于API 22，适用于API 23它工作正常 . 日志对我没有多大帮助，而且我对可能导致此错误发生的想法没有用处 . 它抱怨的类是清单中定义的App类 . 以下是一些可能对分析有用的代码：

清单：

<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">

        android:value="gogame.db" />
    <meta-data

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

App Class（它抱怨的那个不存在）：

public class 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;
}

}

你要踢自己..

在清单包名称中缺少开头的br应该是：br.com.gogame.commons.infra.App

你把它作为.com.gogame.commons.infra.App，它将无法工作，因此找不到类错误
