Background Recording without a preview #30

Hi

I wanted to ask if it is possible to record the frames in the background of an activity without having to show the preview.

HI, Theoritically it is possible, please check usbCameraTest4. It works as Service and can record in background. FYI, app needs Activity to get permanent permission(this is Android specification). If you want to completely hide Activity, finish Activity before setContentView after start Service. saki

Thanks for your answer. I've already figured out an way..

There is another issue. when i record the video with usb cam the video is recorded well but the audio is only noise..when i record without usb cam then the audio is also ok. Do you have any idea why its happening. t happened with your sample project 2 and 5 both.

Hi, Sorry my answer delayed. I assume system software of your device has something trouble on audio(like recent GALAXY series). Try to use other constant for AudioRecord instead of MediaRecorder.AudioSource.MIC. Ex. MediaRecorder.AudioSource.CAMCORDER may help you. saki
