前台 android 服务有时无法正常工作

Question

我在 android 有一个前台服务，每分钟执行一些任务。但是在记录它之后我发现它不会每分钟都触发或发生其他事情。我能做些什么来确保它开火。我应该提一下，我使用的是 React Native，我的任务是在 React Native 端使用 headlessjs 任务，但我认为这不是问题所在。我在我的代码中开始服务，它在调试中工作，但在发布后它不会每分钟触发一次，而是随机触发一次！请帮帮我？


public class TimeCheckerService extends Service {

    private static final int SERVICE_NOTIFICATION_ID = 12345;
    private static final String CHANNEL_ID = "TimeChecker";

    private Handler handler = new Handler();
    private Runnable runnableCode = new Runnable() {
        @Override
        public void run() {
            Context context = getApplicationContext();
            Intent myIntent = new Intent(context, TimeCheckerEventService.class);
            context.startService(myIntent);
            HeadlessJsTaskService.acquireWakeLockNow(context);
            handler.postDelayed(this, 60000);
        }
    };

    private void createNotificationChannel() {
        // Create the NotificationChannel, but only on API 26+ because
        // the NotificationChannel class is new and not in the support library
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_MAX;
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "TimeChecker", importance);
            channel.setDescription("ُسلاما");
            channel.setSound(null, null);
            NotificationManager notificationManager = getSystemService(NotificationManager.class);
            notificationManager.createNotificationChannel(channel);
        }
    }

                        BitmapFactory.decodeResource(getApplicationContext().getResources(), R.mipmap.ic_launcher))
                .setContentIntent(contentIntent).setOngoing(true).setSound(null);
        startForeground(SERVICE_NOTIFICATION_ID, notification.build());
        return START_STICKY;
    }
}

public class TimeCheckerEventService extends HeadlessJsTaskService {
    @Nullable
    protected HeadlessJsTaskConfig getTaskConfig(Intent intent) {
        Bundle extras = intent.getExtras();
        //HeadlessJsRetryPolicy retryPolicy = new LinearCountingRetryPolicy(3,1000);
        return new HeadlessJsTaskConfig(
                "TimeChecker",
                extras != null ? Arguments.fromBundle(extras) : null,
                5000,
                true);
    }
}

            <service

看来我只需要在我的清单中的服务标签上添加 android:process=":custom_text" 以便将服务线程和我的应用程序分开，现在它可以工作了。我希望这对某些人有所帮助。
