Мне нужно найти решение для получения обновлений местоположения в режиме ожидания. Не имеет значения, являются ли обновления непрерывными или каждые 5 минут или более.
На данный момент у меня есть сервис переднего плана, который получает блокировку пробуждения с LocationListener в нем. Приложение также занесено в белый список.
Мой сервис не убивается, когда дремлет, но сигнал GPS есть. Я не могу найти решение, чтобы получить обновление местоположения.
Я также попытался запустить службу с AlarmManager.setExactAndAllowWhileIdle, и служба запускается в дремотном режиме, но местоположение не обновляется.
MainActivity , которая запускает службу кнопкой:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button startTrackingServiceButton = (Button) findViewById(R.id.startTrackingServiceButton);
Button stopTrackingServiceButton = (Button) findViewById(R.id.stopTrackingServiceButton);
askForWhitelistingApp();
if (permissionsGranted()) {
startTrackingServiceButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
askForWhitelistingApp();
startTrackUserForegroundService();
//setServiceWithAlarmManager();
}
});
stopTrackingServiceButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
stopTrackUserForegroundService();
}
});
}else{
ActivityCompat.requestPermissions(this, new String[] {
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION },
10);
}
}
private void setServiceWithAlarmManager(){
Intent intent = new Intent(MainActivity.this, TrackUserForegroundService.class);
intent.setAction(TrackUserForegroundService.ACTION_START_FOREGROUND_SERVICE);
PendingIntent pintent = PendingIntent.getService(MainActivity.this, 0, intent, 0);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Calendar calendar = new GregorianCalendar();
calendar.set(Calendar.MINUTE, 40);
calendar.set(Calendar.SECOND, 20);
calendar.set(Calendar.HOUR, 3);
Long time = calendar.getTimeInMillis();
alarm.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, time, pintent);
