launch automatically when a device is plugged in using the manifest file then it appears the Android system gets the ACTION_USB_DEVICE_ATTACHED intent and then since it knows your application wants to run in that situation it actually sends your application the android.intent.action.MAIN.. to run in that situation it actually sends your application the android.intent.action.MAIN intent.

Even if your app is running and in the foreground when you plug in the USB device and the Android system gets the ACTION_USB_DEVICE_ATTACHED intent it will call onResume in your activity. Unfortunately you cannot just do this @Override public void onResume super.onResume..
