PhoneGap / Android中的屏幕方向

Question

我目前正在PhoneGap中开发一个小型演示，以测试一些功能。我想使用Github提供的PhoneGap-OrientationLock插件，以便能够从JavaScript动态更改屏幕方向，我已经更新了该插件，以便在Cordova中使用它。

我现在的问题是，一旦我想更改屏幕方向，它就会崩溃。即使我尝试setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);使用onCreate方法中的简单操作（从技术上没有使用PhoneGap），我的应用程序也会使用以下调试日志退出启动器：

所以看起来就像我这样调用setRequestedOrientation一样：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    super.loadUrl("file:///android_asset/www/index.html");
}

我的应用程序调用onDestroy并返回启动器。我只是不了解Android概念吗？有人知道吗？

您应该android:configChanges="orientation|keyboardHidden"在<activity>出现的第一个清单中添加 Android Manifest 。我遇到了同样的问题，它也使我的应用程序崩溃了。
