Question

我的android程序中有一个嵌入式Unity3d项目。 3D项目在立体视图中打开，可以在DayDream耳机中使用（尽管它总是说控制器已断开连接，这是一个单独的问题）。当我点击x退出VR视图时，它会按预期返回到Android应用程序，但是1秒后应用程序翻转到横向并崩溃。

以下是问题的整个堆栈跟踪：

我的代码附在下面主要活动

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));
            }
        });
    }
}

呼吁统一的活动

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);
    }
}

可能有几个不同的问题。一个是堆栈跟踪中格式错误的json。

然而，屏幕旋转时的崩溃通常是别的。

似乎有一些任务正在完成对旧视图的引用。当应用程序切换到横向时，活动将被销毁并重新创建，并重新创建所有视图。如果长时间运行的进程携带对垃圾收集视图的引用，则您的应用程序将崩溃。

快速判断这实际上是否是问题的方法是将其添加到调用活动下的清单中。这将强制调用活动保持纵向模式。如果应用程序在退出后没有崩溃，则可能存在一个持有对已销毁视图的引用的进程。

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