Android ICS native lockscreen

I've been looking for the past 2 days on SW, google and so on. I'm looking for a way to implement an activity that comes with the native Android ICS lockscreen as the one shown in the screens below. Those screens come from Player Pro but I noticed that also other players ( PlayerPro for instance ) have the same feature that looks exactly the same, that's why i think it's something native or at least, there is a common way to implement it.

So far I only managed to get and Activity that replace the lockscreen using these flags:

  • WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
  • WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD

with a BroadCaseReciever on these events:

  • Intent.ACTION_SCREEN_ON
  • Intent.ACTION_SCREEN_OFF
  • Intent.ACTION_USER_PRESENT

My problem is that i want my activity to be shown with the lockscreen not replacing it. Do you guys know how to achieve this?

is there a native-hidden API to do this?

can you guys link me some sample that implement this particular feature?

thanks in advance ;)

Solution

  • I think you might be looking for the Audio Controls "remote view" (RemoteControlClient) API added in Android 4.0 (API level 14). I found the RemoteControlClient API in the Android developer docs that:

    enables exposing information meant to be consumed by remote controls capable of displaying metadata, artwork and media transport control buttons.

    (It was linked off of this page.)

    Note: I have never used this API myself, so I apologize if this does not work for you.
