如何定期将我的当前位置发送到网络服务？

Question

我想在后台定期将我当前的位置信息发送到数据库。例如;每 5 分钟一次。即使用户不在应用程序中，位置也必须在后台发送。最好的方法是什么？你能给我什么建议？

public class AlarmReceiver extends BroadcastReceiver {

private FusedLocationProviderClient client;

private Context context;

@Override
public void onReceive(Context context, Intent intent) {

    this.context = context;

    client = LocationServices.getFusedLocationProviderClient(context);

    if (ActivityCompat.checkSelfPermission(context, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    client = LocationServices.getFusedLocationProviderClient(context);

    client.getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {
        @Override
        public void onSuccess(Location location) {

            // You can send to your webservice in here.
            Log.i("TEST_LOCATION", location.getLatitude()+"");
        }
    });

  }
}

您应该在 Activity class 开始。

    Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), REQUEST_CODE, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, Calendar.getInstance().getTimeInMillis(), 5*60*1000, pendingIntent);

并且您应该在清单中添加。

<receiver android:name=".AlarmReceiver" />

您可以通过使用 Pendingintent 和 BroadcastReceiver 来实现。
