在 AndroidManifest.xml 文件中添加以下代码：

在网络请求的代码中，使用 WakefulBroadcastReceiver 来确保设备在执行网络请求时保持唤醒状态：

public class MyWakefulService extends IntentService {
    public MyWakefulService() {
        super("MyWakefulService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        PowerManager.WakeLock lock = null;
        try {
            PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
            lock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakefulService");
            lock.acquire();
            //执行网络请求的代码
        } finally {
            if (lock != null) {
                lock.release();
            }
        }
        MyWakefulReceiver.completeWakefulIntent(intent);
    }
}

public class MyWakefulReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, MyWakefulService.class);
        startWakefulService(context, service);
    }
}

在需要执行网络请求的地方，使用以下代码触发 WakefulBroadcastReceiver：

ComponentName receiver = new ComponentName(context, MyWakefulReceiver.class);
PackageManager packageManager = context.getPackageManager();
packageManager.setComponentEnabledSetting(receiver, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
Intent alarmIntent = new Intent(context, MyWakefulReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 5000, pendingIntent);
