问题 I'm trying to open the Android camera and keep it running in the background constantly across multiple activities for a variety of long-running frame consumers for both Glass and non-Glass devices. This means I can not simply close the camera when one activity stops and re-open it when the next one starts; it must stay open the entire time. I've tried creating a SurfaceView using the Application as the Context (rather than an Activity) and adding it directly to the WindowManager. This does

问题 Details: I would like to add a code drawn line (like you draw with canvas/paint) and display it over other applications.

问题 I have a custom RelativeLayout and I even have set setLayoutTransition(null); .

问题 I have a service that adds some views to the window manager (something like facebook's chat heads). This views stay on top of everything all the time, even when I'm on the camera app. Is it possible to know when some activity (like the camera or a video player) is using full screen so I can hide my views? Edit: There's something called View.OnSystemUiVisibilityChangeListener but it requires API 11. My target is 9, but it looks like this is exactly what I need. Any alternative for API 9? 回答1:
