Sometimes, it's crucial for services to run as the application starts. Also, sometimes it is important to do some cleanup work before we terminate it. In the following example, we will extend the Journaler application to listen for these broadcast messages and do some work. First thing that we will do is create two classes that extend the BroadcastReceiver class:
- BootReceiver: This is to handle the system boot event
- ShutdownReceiver: This is to handle the system shutdown event
Register them in your manifest file as follows:
<manifest ... > ... <receiver android:name=".receiver.BootReceiver" android:enabled="true" android:exported="false"> <intent-filter> <action android:name= "android.intent.action.BOOT_COMPLETED" ...
