- Make sure to add the service to your AndroidManifest.xml
- Edit the appropriate fields in the class with the information required
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:versionName="1.0">
<receiver android:name=".MyReceiver" android:enabled="true" android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name="com.jessefarebro.mqtt.MqttService" android:exported="false" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
