IllegalArgumentException：クラスcom.e.piのデフォルトのコンストラクタにアクセスできません

Question

アプリケーションをデバッグモードで実行していて、Androidスタジオから実行している場合、アプリケーションは正常に動作します。しかし、ビルドする際に、その後APKに署名し、次のスタックトレースとの電話でアプリがクラッシュをインストール：

私はProGuardのを削除し、問題を解決しないことを好むだろう、任意の助けいただければ幸いです！以下は

アプリケーションコードです：

public class TestApplication extends Application { 

    public static final String TAG = "ALL"; 
    private static TestApplication mInstance; 
    private RequestQueue mRequestQueue; 

    public TestApplication()

     mInstance = this; 
    }

     super.onCreate();

     Parse.enableLocalDatastore(this);

       .clientKey(BuildConfig.PARSE_CLIENT_KEY) 
       .server(server) 
       .build()); 

     // Logging set to help debug issues, remove before releasing your app. 
     OneSignal.setLogLevel(OneSignal.LOG_LEVEL.DEBUG, OneSignal.LOG_LEVEL.WARN); 

     OneSignal.startInit(this) 
       .setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())

あなたはsupport.annotationから@Keepを使用して維持したいクラスやメソッドに注釈を付けることができます。
