Your device on android 8?

[IshanFx]

No, its 5. I thinks it because startcamera run on main thread.

I am experiencing the same issue. My app locks up after taking a picture from the service.

[minionsong]

Same as me. I tried to use other thread instead of main looper but service cannot get image data from that thread.

I think the camera.open is launching on main thread and thats why its blocking UI and leading to lags..try https://github.com/KAditi/Camera-Application. It gives no problem; it uses asynctask.

I think some changes in HiddenCameraService.java can solve this issue.

Change this line (in HiddenCameraService.java, line 130)
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
to a line
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE

@gaynor @sknepal @shobhan1595 ☝🏻try this too

@kevalpatel2106 What you think about this? Can we make a change?
