Start a service on firebase datachange Listener?












0















I have been working on an application where i need to trigger a defined service on firebase datachange listener.
I tried using IntentService but it doesn't make it to happen.
I want to start a background service when there's a change occurs in firebase database.
Hope you could help me out.



Manifest:



 <service 
android:name=".modules.call.notifications.CallNotificationService"
android:exported="false">
</service>


Service:



class CallNotificationService : IntentService(CallNotificationService::class.simpleName){

private var pActivity = MainBaseActivity()
override fun onHandleIntent(intent: Intent?) {
VFirebaseQueryManager.getUserReference(pActivity?.profile?.user_id?.toLong()!!)?.addValueEventListener(object : ValueEventListener{
override fun onCancelled(p0: DatabaseError) {
print("a")
}

override fun onDataChange(dataSnapshot: DataSnapshot) {
val notifications = dataSnapshot.getValue(Profile::class.java)
if(notifications!=null){
if(notifications?.action?.equals("inCall")!!){
intent?.putExtra(ApplicationConstants.INCOMING_CALL_DATA,notifications)
intent?.setClass(this@CallNotificationService, CallActivity::class.java)
applicationContext.startActivity(intent)
}
}
}
})
}
}

  • You can't keep a database listener active indefinitely. When the app is killed, the listener is gone.
