    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG,"action : "+intent.getAction());
        if (Objects.requireNonNull(intent.getAction()).equals(Intent.ACTION_BOOT_COMPLETED)){
            Log.d(TAG,"receive boot completes : "+intent.getAction());
            @SuppressLint("StaticFieldLeak")
            AsyncTask task = new AsyncTask() {
                @Override
                protected Object doInBackground(Object[] objects) {
                    try {
                        Thread.sleep(5000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    return null;
                }

                @Override
                protected void onPostExecute(Object o) {
                    super.onPostExecute(o);
                    context.startForegroundService(new Intent(context, StatUpdateService.class));
                }
            };

            task.execute();

Android does not auto-start any application until you manually launch it at least once. After that, the applications will automatically start on each Android boot.

Add android.permission.RECEIVE_BOOT_COMPLETED permission in your manifest.

When Android finishes booting and is ready to start the home activity, the home event is sent and qualifying applications identify themselves as bootable candidates. The system sends out the android.intent.category.HOME and android.intent.category.DEFAULT intents when it's done initializing.
