Android Camera Capture button click

I am developing an app for a Bluetooth device in which I have to take a picture on Bluetooth button click.

I have coded for the receiver of BLE device and I get the button clicked event in receiver, But main problem is capture image code does not work.

I have tried following code in receiver 

Intent intent1 = new Intent("android.intent.action.CAMERA_BUTTON");
intent1.putExtra("android.intent.extra.KEY_EVENT", new KeyEvent(0, KeyEvent.KEYCODE_CAMERA));
sendOrderedBroadcast(intent1, null);
intent1 = new Intent("android.intent.action.CAMERA_BUTTON");
intent1.putExtra("android.intent.extra.KEY_EVENT", new KeyEvent(1, KeyEvent.KEYCODE_CAMERA));
sendOrderedBroadcast(intent1, null);

I have also tried changing KEYCODE_CAMERA to KEYCODE_VOLUME_UP but this too do not work.

What do I code to get camera capture button event?

you should try doing like this.

 @Override
public boolean dispatchKeyEvent(KeyEvent event) {
    int action = event.getAction();
    int keyCode = event.getKeyCode();
        switch (keyCode) {
        case KeyEvent.KEYCODE_VOLUME_UP:
            if (action == KeyEvent.ACTION_DOWN) {
                //TODO
            }
            return true;
        case KeyEvent.KEYCODE_VOLUME_DOWN:
            if (action == KeyEvent.ACTION_DOWN) {
                //TODO
            }
            return true;
        default:
            return super.dispatchKeyEvent(event);
        }
    }

Refer official documentation to develop a camera app.

Refer sub section Capturing pictures which suggests to use Camera.takePicture() method to capture image.
