在Android上从ANE（Adobe Native Extension）运行新的UI后台活动

Question

我尝试根据YouTube API制作Android ANE。

YouTube API需要启动新活动，当通过ANE调用时，禁用Air应用活动，直到用户点击后退按钮。

我有什么选择在后台运行YouTube活动，以便Air应用程序保持互动？

活动类：

/**


* A sample showing how to use the ActionBar as an overlay when the video is playing in fullscreen.
 *
 * The ActionBar is the only view allowed to overlay the player, so it is a useful place to put
 * custom application controls when the video is in fullscreen. The ActionBar can not change back
 * and forth between normal mode and overlay mode, so to make sure our application's content
 * is not covered by the ActionBar we want to pad our root view when we are not in fullscreen.
