java - AlarmManager 在应用程序关闭时不起作用

Question

public class background_alarm extends BroadcastReceiver {

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

         //CODE EVERY X MINUTES
} }

主要 Activity

public class MainActivity extends AppCompatActivity {



AlarmManager alarmManager;
PendingIntent pendingIntent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

   AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

    Intent intent = new Intent(this, background_alarm.class);
    intent.putExtra("UserNumber", UserLogged.getNumeroTelefono());

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);


    Long intervalMillis = 1L * 60L * 1000L; //IT'S ONLY FOR TEST 1 MINUTES
    Long triggerAtMillis = System.currentTimeMillis() + intervalMillis;

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, triggerAtMillis, intervalMillis, pendingIntent);

}

当应用程序关闭时，它不再起作用......有一个解决方案可以运行吗？注意:当应用程序运行时此工作

您的设备可能正在进入打瞌睡模式。在后台警报类中使用 setAndAllowWhileIdle() 或 setExactAndAllowWhileIdle() 方法 https://developer.android.com/training/monitoring-device-state/doze-standby
