更改统一播放器的屏幕方向时我的应用程序崩溃

Question

我的 android 应用程序可以在点击时打开统一播放器。我的统一播放器表现符合预期。

问题： 在更改屏幕旋转时，应用程序崩溃。

调试控制台输出：

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：

Either "fixing of screen changing app crash" or "force landscape view" will make my resolution.

我试过将统一播放器设置更改为横向左。
我已经尝试从 android 清单文件中删除我的 orientation|layoutDirection|screenLayout。
我试过添加 screenOrientation="landscape/user/nosensor/fulluser"

Answer 1

我在谷歌上搜索了很多关于更改方向时 Unity Player 崩溃的问题，但没有找到有用的解决方案。

因此，考虑到我的可行性，我将方向锁定为 "landscape" 模式。

为此，

第 1 步：Unity 播放器设置

Go to Edit > Project Settings > Player it will open Player Settings in the inspector.

Select the target platform from the list.

Click the Resolution and Presentation section.

Set the Default Orientation to Landscape left / right.

参考此博客：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，还要以编程方式设置方向。

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