This article shows an example of how Android can be implemented to stop Service from activity. To share with you for your reference, as follows:

1. Register Service with AndroidManifest.xml

<service android:name=".service.SensorService" >
  <intent-filter>
    <action android:name="ITOP.MOBILE.SIMPLE.SERVICE.SENSORSERVICE"/>
  </intent-filter>
</service>

2. Called in Activity

final Intent intent = new Intent();
intent.setAction("ITOP.MOBILE.SIMPLE.SERVICE.SENSORSERVICE");
stopService(intent);

I hope this article is helpful to Android program design.
