檢查服務是否在Android上運行？

Question

我想檢查服務是否正在運行

public class startServiceOrNo {
public static void startServiceIfItsNotRuning(Class<?> class1, Context context) {
    ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (class1.getName().equals(service.service.getClassName())) {
            Lg.d("servisstart SERVICE ALREADY START" + class1.getName());
            return;
        }
    }
    Lg.d("servisstart SSERVICE NEW SERVIS " + class1.getName());
    context.startService(new Intent(context, class1));
}

並使用它startServiceOrNo.startServiceIfItsNotRuning（OfflineChopsMonitor.class，this）

如果我從一個班級檢查服務，但如果我從另一個班級檢查相同的服務，則檢查不起作用

1.）在Activity類中：

private boolean isMyServiceRunning(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}

2.）在非活動類（BroadcastReceiver）中：

private boolean isMyServiceRunning(Class<?> serviceClass,Context context) {
        ActivityManager manager = (ActivityManager)context. getSystemService(Context.ACTIVITY_SERVICE);
        for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (serviceClass.getName().equals(service.service.getClassName())) {
                Log.i("Service already","running");
                return true;
            }
        }
        Log.i("Service not","running");
        return false;
    }

您為什么不讓服務本身解決呢？

public class MyService extends Service
{
    private boolean mRunning;

    @Override
    public void onCreate()
    {
        super.onCreate();
        mRunning = false;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId)
    {
        if (!mRunning) {
            mRunning = true;
            // do something
        }
        return super.onStartCommand(intent, flags, startId);
    }
}

Answer 3

我在活動中使用以下內容：

private boolean isMyServiceRunning(Class<?> serviceClass) {
  ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
  for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
    if (serviceClass.getName().equals(service.service.getClassName())) {
        return true;
    }
  }
  return false;
}

檢查服務是否正在運行，如果我的情況是： OpenVPNService.class是我的服務類

if (isMyServiceRunning(OpenVPNService.class)) {
                success_txt.setVisibility(View.VISIBLE);
            } else {
                success_txt.setVisibility(View.GONE);
            }





 private boolean isMyServiceRunning(Class<?> serviceClass) {
        ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (serviceClass.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
        return false;
    }

您可以在Kotlin中使用此方法

fun Activity.isServiceRunning(serviceClassName: String): Boolean {
    val manager = getSystemService(ACTIVITY_SERVICE) as ActivityManager
    return manager.getRunningServices(Integer.MAX_VALUE).any { it.service.className == serviceClassName }
}
