PhoneGap/Android中的屏幕方向

我目前正在PhoneGap中开发一个小演示，以测试一些功能。我想使用能够从JavaScript动态改变我的屏幕方向，我已经更新了插件以在Cordova中使用它

我现在的问题是，只要我想改变屏幕方向，它就会崩溃。即使我试着做一些简单的事情，比如setRequestedOrientationActivityInfo.SCREEN\u ORIENTATION\u scape；在我的onCreate方法中没有使用PhoneGap，我的应用程序只是使用以下调试日志退出到启动器：

看起来只要我调用setRequestedOrientation，就像这样：

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并返回到启动器。我只是不理解Android的概念吗？任何人都有线索吗？

您应该在第一个出现的android清单中添加隐藏在android清单中的android:configChanges=orientation | Keyboard。我也遇到了同样的问题，它也使我的应用程序崩溃。
