I had seen many questions on stack but no one is telling if a Fail to connect to camera service will occur, how to get rid of this RuntimeException.

I have an camera application its working fine, I already take care to release the resources but if somehow user install the other application which not releasing the resources properly, my application facing RuntimeException: Fail to connect to camera Service and hence got crashed, want to avoid this situation.

If i click on original camera application it shows me a AlertDialog 

Camera error: Cannot connect to camera.

That’s what i exactly want to handle this. I am trying this code to handle it but cant succeed yet.

try {
    camera = Camera.open();
    camera.setDisplayOrientation(90);
} catch (RuntimeException e) {
    // TODO: handle exception
    Log.d("Inside RunTime exception", e+"//");
    camera.setErrorCallback(errorCallback);
    reConnectCameraVideo();
} catch(Exception e) {
    finish();
}

but camera object returning null on camera.setErrorCallback because it wont open.

    setErrorCallback() cannot be used for the case where the Camera will not open. You appear to be trying to still use the Camera — AFAIK this is impossible until the user reboots their phone if some other app leaked the Camera. Simply display your own message to that effect.

    Also:

    • Use an error logging service, like ACRA, Flurry, BugSense, etc.

    • Never blindly finish an activity due to an exception, as in your last catch block. Always do something to let the user and/or you (via the error logging service) know about the exception
