        public void onFinish() {

        }
        @Override

What do you mean with "without showing preview"? You can just store the path of the image without viewing it.. — HB., Dec 16 '17 at 17:09
this project is for taxi , i will get location of taxi, and customers photo to db, this operations will be done when taximeter starts automaticly without human control — hkn, Dec 16 '17 at 17:21
i know java but dont know android is it posible to take photo + get location and put them to database with functions under CountDownTimer if not i will try to find another strategy — hkn, Dec 16 '17 at 18:46
Yes it is definitely possible. Once the image is taken you can temporarily store it to the device, then upload it to the database, when successfully stored in database you can delete it from the device. The location is simple, once the image is taken you get the location and store it and it will work perfectly when using a CountdownTimer — HB., Dec 16 '17 at 18:59
hımm i got rid off the location thing btw just camera left i think i need to take permissions then take photo — hkn, Dec 16 '17 at 20:33

Below service works percfectly on api19

public class CapPhoto extends Service {
private Camera mCamera;

@Override
public void onCreate() {
    super.onCreate();
    Log.d("CAM", "start");

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy =
                new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
    Thread myThread = null;


}

@Override
public void onStart(Intent intent, int startId) {
    takePhoto();
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

private void takePhoto() {

        SystemClock.sleep(1000);

        Camera.getCameraInfo(camIdx, cameraInfo);

        try {
            camera = Camera.open(camIdx);
        } catch (RuntimeException e) {
