我的项目在序列化/反序列化期间实现了一个TypeAdapterin Gson来保留对象的多态性状态.无论如何,该项目在开发测试期间工作正常,但是当它通过proguard混淆和测试发布时,它只会崩溃.

我的Gson特定的proguard配置是:

##---------------Begin: proguard …

我的申请是无法启动的.Firebase.setAndroidContext()在我的onCreate()方法中导致NoSuchMethodException.见下文:

protected Firebase ref;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    String firebaseUrl = getResources().getString(R.string.firebase_url);
    Firebase.setAndroidContext(getApplicationContext());
    ref = new Firebase(firebaseUrl);

} 

我还设置了一个应用程序:

public class FirebaseApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Firebase.setAndroidContext(this);
    }
}

这导致来自logcat的以下堆栈跟踪:
