我是Android新手。 我希望仅在服务启动时使用android服务来阻止通话

Question

This is the code should be run only when the service is running. And the service should be stopped in some other part.

public void onReceive(Context context, Intent intent)
{

    this.context=context;
    this.intent=intent;

    if (!intent.getAction().equals("android.intent.action.PHONE_STATE"))
        return;


    else
    {
            number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

            if (Callblockactivity.blockList.contains(new Blacklist(number))) {
                System.out.println("i");
            }

            else {

                    disconnectPhoneItelephony(context);
                    return;

            }
       }
    }

Now, the service should be started in mainactivity as follow.

 if (speed >10) {
  //service should be started.
  }

     else {
  //service should be stopped
   }

Please help with this.

use startService to start a Service. Use stopSelf or stopService to stop your service.

And you may use a static boolean variable inside your service in order to keep the flag whether the service is running. Instead of that variable also you may dynamically register a receiver when you start your service, and unregister it when you stop the service.
