android - Android 中的嵌入式 Unity 使应用程序崩溃

我的 android 程序中有一个嵌入式 Unity3d 项目。 3d 项目在立体 View 中打开良好，可用于 DayDream 耳机(尽管它总是说 Controller 已断开连接，这是一个单独的问题)。当我单击 x 退出 VR View 时，它按预期返回到 Android 应用程序，但 1 秒后应用程序翻转到横向并崩溃。

下面是问题的完整堆栈跟踪:

最佳答案

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另外一回事。

似乎有一些任务正在完成对您旧 View 的引用。当应用程序切换到横向时， Activity 将被销毁并重新创建，并且您的所有 View 都会重新创建。如果长时间运行的进程正在引用被垃圾收集的 View ，您的应用程序将会崩溃。

判断这是否真的是问题的一种快速方法是将其添加到调用 Activity 下的 list 中。这将强制调用 Activity 保持纵向模式。如果应用程序在退出后没有崩溃，那么很可能有一个进程持有对已销毁 View 的引用。

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