Amazon Device Messaging在Android模拟器上崩溃了运行时，如何解决？

如何解决Amazon Device Messaging在Android模拟器上崩溃了运行时，如何解决？

几乎所有关于stackover的答案，我已经在过去5-6个小时内尝试过，请不要将重复标记为：）

我已经推荐Amazon Device Messaging documentation集成到我的android项目中，一切都可以正常编译，但是当我运行该项目时，它会崩溃并显示一条消息

    FATAL EXCEPTION: main
    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.MainActivity}: java.lang.RuntimeException: 
Stub! You are bundling a stubbed jar in the apk! Please move it to the classpath instead.

通过在AndroidManifest.xml中进行如下标记，我使用了“如果ADM不可用则正常降级”方法

<!-- You must explicitly enable ADM. You must also declare whether your application will run with or without ADM.
        If you specify android:required="false",your app must degrade gracefully when ADM is unavailable. -->
        <amazon:enable-feature android:name="com.amazon.device.messaging"
            android:required="false" />

此外，在文件MainActivity中，我正在检查ADM的可用性，如以下代码所示

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //some other codes here
    boolean admAvailable = false;
    try {
        Class.forName( "com.amazon.device.messaging.ADM" );
        admAvailable = true ;
    }
    catch (ClassNotFoundException e) {
        // Handle the exception.
    }
    if(admAvailable) {
        ADMManifest.checkManifestAuthoredProperly(getApplicationContext());
    }
}
