我有我的 android 应用程序，点击即可打开统一播放器。我的统一播放器按预期执行。

问题：在更改屏幕旋转时，应用程序崩溃。

调试控制台输出：

I/Unity: StopVuforia

W/Unity: Timeout while trying detaching primary window.

AndroidManifest

<activity
            android:name=".UnityPlayerActivity"
            android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale|layoutDirection|density"
            android:label="@string/app_name"
            android:launchMode="singleTask"
            android:screenOrientation="landscape"
            android:theme="@style/UnityThemeSelector">
            <meta-data
                android:name="unityplayer.UnityActivity"
                android:value="true" />
        </activity>

解决方法：

“修复屏幕更改应用程序崩溃”或“强制横向视图”将使我的解决方案。

  1. 我尝试将统一播放器设置更改为横向左侧。
  2. 我试过orientation|layoutDirection|screenLayout从 android 清单文件中删除我的。
  3. 我试过添加screenOrientation="landscape/user/nosensor/fulluser"

我在更改方向时搜索了很多 Unity Player 崩溃，但没有找到有用的解决方案。

因此，由于这是我的可行性，我将我的方向锁定为“风景”模式。

为了这，

第 1 步：Unity 播放器设置

转到编辑 > 项目设置 > 播放器，它将在检查器中打开播放器设置。

从列表中选择目标平台。

单击“分辨率和演示文稿”部分。

将默认方向设置为横向左/右。

请参阅此博客：https ://answers.unity.com/questions/774186/landscape-mode-only.html

第 2 步：Android 代码更改。

在清单文件中，

<activity
            android:name=".UnityPlayerActivity"
            android:label="@string/app_name"
            android:launchMode="singleTask"
            android:screenOrientation="landscape"
            android:theme="@style/UnityThemeSelector">
            <meta-data
                android:name="unityplayer.UnityActivity"
                android:value="true" />
</activity>

此外，还要以编程方式进行定向。

private int screenOrientation;
// lock screen orientation to landscape mode only.
screenOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
setRequestedOrientation(screenOrientation);
