嵌入Unity在Android中导致应用程序崩溃

androidunity-game-engine
9
我在我的安卓程序中嵌入了一个Unity3d项目。该3d项目可以在DayDream头戴式设备上正常打开以进行立体视图操作（尽管它总是显示控制器断开连接，这是一个单独的问题）。当我点击退出VR视图的X时，它回到了预期的安卓应用程序，但1秒后，应用程序会翻转为横屏并崩溃。
以下是有关此问题的完整堆栈跟踪：

以下是我的代码 主活动

public class MainActivity extends AppCompatActivity {

    Button unityVRButton;

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

        unityVRButton = (Button)findViewById(R.id.open_unity);
        unityVRButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(MainActivity.this,GameActivity.class));
            }
        });
    }
}

调用Unity的活动

import android.os.Bundle;

import com.rbw.TestVR.UnityPlayerActivity;

/**
 * Created by kshah on 3/15/2018.
 */

public class GameActivity extends UnityPlayerActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

没有代码示例，将很难提供帮助... - N0un
我会添加一些代码。 - Kunal Shah
这可能是一个资源释放问题。也许有一种方法能够在UnityPlayerActivity中释放所有的Unity上下文，你应该确保在回到你的MainActivity之前调用它（例如onPause，onDestroy）。另外，你确定提供了正确的堆栈跟踪吗？ - N0un

可能有几个不同的问题。其中一个是堆栈跟踪中的格式错误的json。

然而，屏幕旋转时的崩溃通常是其他原因。

似乎有一些任务正在完成，并引用您旧视图的内容。当应用程序切换到横向模式时，活动将被销毁并重新创建，所有视图都将被重新创建。如果长时间运行的进程正在引用已经被垃圾回收的视图，则您的应用程序将崩溃。

快速检查是否实际上存在此问题的方法是在调用活动下添加此内容到您的清单中。这将强制调用活动保持纵向模式。如果应用程序退出后没有崩溃，则很可能存在一个进程，该进程保留对已销毁视图的引用。

  <activity
android:name=".MyActivity"
android:label="@string/title_my_activity"
android:screenOrientation="portrait" />

这里有更多信息： http://code.hootsuite.com/orientation-changes-on-android/

我已经添加了一个竖屏布局的XML文件，以便在旋转方向时不会崩溃。但现在应用程序会短暂地打开一个黑屏，看起来像是要打开Unity，但大约一秒钟后就会关闭并返回应用程序视图。我已经更新了这个问题的堆栈跟踪。 - Kunal Shah
