你只是簡單的注冊了<service android:name="com.Sevices.mqtt.ReceivingMessageService"/>
并沒有給這個service起個名字，所以Intent intent = new Intent("com.Sevices.mqtt.ReceivingMessageService");
這樣調用是啟動不了你的service的，請改為類似如下：
Intent intent = new Intent(MainActivity.this,com.Sevices.mqtt.ReceivingMessageService.class);
或者在manifest中加個別名：
<service android:name="com.Sevices.mqtt.ReceivingMessageService">
<intent-filter>
<action android:name="com.Sevices.mqtt.ReceivingMessageService" />
</intent-filter>
</service>
