Launch the video recorder from BlackBerry app - blackberry

Question

Are there any APIs to launch the video recording app? I want to invoke the video recorder through my app, record a video, then save that video to the server.

Answer 1

ApplicationManager.getApplicationManager().launch("net_rim_bb_videorecorder");
This will help you open the application. If you want to start recording, you may need to simulate a key input.
btw: CameraArguments(ARG_VIDEO_RECORDER) is introduced since jde4.7, so it's not compatible with the previous OS's. So the previous method is better.

Answer 2

Finally find the solution from BB docs .
