android - 在空闲模式下获取位置更新

Question

在打盹模式下，我必须找到一种解决方案来获取位置更新。更新是连续的还是每 5 分钟或更长时间都没有关系。目前我有一个前台服务，它获取一个带有 LocationListener 的唤醒锁。该应用程序也被列入白名单。我的服务在打瞌睡时不会被杀死，但 gps 信号会。我找不到获取位置更新的解决方案。我还尝试使用 AlarmManager.setExactAndAllowWhileIdle 启动服务，服务以打瞌睡状态启动，但仍然没有位置更新。

使用按钮启动服务的MainActivity：

@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);
}

private void startTrackUserForegroundService(){

}

    intent.setAction(TrackUserForegroundService.ACTION_STOP_FOREGROUND_SERVICE);
    startService(intent);
}

private boolean permissionsGranted() {
    return ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
            PackageManager.PERMISSION_GRANTED &&
            ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
