Android background service not starting

I have read multiple threads on this issue but none of them solved my problem, so I gave up and decided to write this.
I have a service (right now it's a background service but I am going to turn it into a foreground service) which monitors the battery level so it can notify the user when it reaches a certain percentage.
abstract class MonitoringService : Service() {
private var maxPercentage: Int = -1
private var thread: Thread? = null
private lateinit var batteryManager: BatteryManager
override fun onBind(intent: Intent?): IBinder? {
return null
}
override fun onCreate() {
batteryManager = getSystemService(BATTERY_SERVICE) as BatteryManager
Log.d(null, "created service")
}
override fun onDestroy() {
thread?.interrupt()
updateServiceState(false)
Log.d(null, "destroyed service")
}
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
println("started service")
if (intent == null) {
stopSelf(startId)
updateServiceState(false)
report(applicationContext, "service started with intent null")
return START_NOT_STICKY
}
when (intent.action) {
ACTION_START_SERVICE -> {
// if a thread is already active interrupt it
thread?.interrupt()
if (updateMaxPercentage(intent, startId) == 1) return START_NOT_STICKY
thread = Thread(Runnable {
while (true) {
if (batteryManager.isCharging && batteryManager.getIntProperty(
BatteryManager.BATTERY_PROPERTY_CAPACITY
) == maxPercentage
) {
Log.d(null, "time to do it")
}
Log.d(null, "time to not do it")
try {
// sleep for 1 minute
Thread.sleep(60000)
} catch (exception: InterruptedException) {
stopSelf(startId)
updateServiceState(false)
return#Runnable
}
}
})
thread?.start()
updateServiceState(true)
}
ACTION_STOP_SERVICE -> {
thread?.interrupt()
stopSelf(startId)
updateServiceState(false)
return START_NOT_STICKY
}
ACTION_UPDATE_SERVICE -> if (updateMaxPercentage(intent, startId) == 1) return START_NOT_STICKY
else -> {
stopSelf(startId)
updateServiceState(false)
report(applicationContext, "service started with action null")
return START_NOT_STICKY
}
}
return START_REDELIVER_INTENT
}
}
I start the service like so from my activity
private fun start() {
val serviceIntent = Intent(applicationContext, MonitoringService::class.java)
serviceIntent.action = ACTION_START_SERVICE
serviceIntent.putExtra("maxPercentage", maxPercentage)
println(startService(intent))
Log.d(null, "startService")
}
This is my AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>

I am testing this on an Android 11 device. The logs show no errors but the service doesn't start.
Thanks.

Remove the abstract keyword from your MonitoringService declaration:
class MonitoringService : Service()
By declaring it abstract, you are saying that nothing can create an instance of that class.

Kotlin: Starting service after BroadcastReceiver not working

I`m trying to build a service that detects if the screen of a device is locked/unlocked (which I will later user as a native module in React). However, it seems like my service is not starting, and I don't receive the expected logs. Where is my mistake? (It's my first time dealing with native android & Kotlin, so apologies if this is a dumb question, and duplicates were related to java code)..
I have defined a Broadcast Receiver for each event here:
ScreenOnReceiver.kt
class screenOnReceiver: BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
if(intent!!.action == Intent.ACTION_SCREEN_ON) {
val screenOff = false
val i = Intent(context, PowerButtonService::class.java)
i.putExtra("screenState", screenOff)
context!!.startService(i)
}
}
}
ScreenOffReceiver.kt
class screenOffReceiver: BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
if(intent!!.action == Intent.ACTION_SCREEN_ON) {
val screenOff = false
val i = Intent(context, PowerButtonService::class.java)
i.putExtra("screenState", screenOff)
context!!.startService(i)
}
}
}
ScreenChangeService.kt:
class ScreenChangeService: Service() {
override fun onBind(p0: Intent?): IBinder? = null
override fun onCreate() {
val screenOnReceiver = screenONReceiver()
val screenOnFilter = IntentFilter(Intent.ACTION_SCREEN_ON)
registerReceiver(screenOnReceiver, screenOnFilter)
val screenOffReceiver = screenOffReceiver()
val screenOffFilter = IntentFilter(Intent.ACTION_SCREEN_OFF)
registerReceiver(screenOffreceiver, screenOffFilter)
}
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
val screenState = intent!!.getBooleanExtra("screenState", false)
if (screenState == true) {
Log.d("TAG", "Screen On")
} else {
Log.d("TAG", "Screen Off")
}
return START_NOT_STICKY
}
}

Android SIP API - Receive Incoming Call

I creating softphone application using Android SIP API (https://developer.android.com/guide/topics/connectivity/sip) and I have successfully registered to my Asterisk server and I can call another peer on another softphone. I can hear voice on both sides and everything works perfect.
Now, I have problem receiving call from another softphone. onRinging method is never executed. On the other softphone I am getting status RINGING, but in my app that call is never received.
I have created IncomingCallReceiver class and also WalkieTalkieActivity, but none of them is doing its job (most probably I am doing something wrong, or I did not initiate some of them, or call or whatever...).
I am stuck on receiving the calls. Also the official documentation is not clear to me.
If there is anyone here to help me and guide me to the solution, I would be very grateful.
Here is my MainActivity class:

I added OtpBroadcastReceiver and registred it, but I can't seem to get the messages from it

Here is my fragment -
#SuppressLint("HardwareIds")
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
mPresenter = VerifyOtpPresenter(this)
androidId = Settings.Secure.getString(activity?.contentResolver, Settings.Secure.ANDROID_ID)
mPresenter.requestOtp(phoneNumber)
initClickAndTextListeners()
initOtpCountdownTimer()
}
/**

*/
override fun requestOtp(phoneNumber: Long) {
OtpNetworking.requestOtp(phoneNumber, object : OtpNetworking.RequestOtpCallback {
override fun onSuccess() {
Toast.makeText(context, getString(R.string.verify_otp_fragment_sms_arrived), Toast.LENGTH_SHORT).show()
startSmsRetriever()
}
override fun onError(reason: String) {
Toast.makeText(context, reason, Toast.LENGTH_SHORT).show()
}
})
}
private fun startSmsRetriever() {
val client = SmsRetriever.getClient(context!!)
val task = client.startSmsRetriever()
task.addOnSuccessListener {
Toast.makeText(context, "Successfully added retriever", Toast.LENGTH_SHORT).show()
}
task.addOnFailureListener {
Toast.makeText(context, "Failed to get SMS", Toast.LENGTH_SHORT).show()
}
}
here is my OtpBroadcastReceiver -
class OtpBroadcastReceiver : BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent) {
Toast.makeText(context, "onReceive", Toast.LENGTH_SHORT).show()
if (SmsRetriever.SMS_RETRIEVED_ACTION == intent.action) {
val extras = intent.extras
val status: Status? = extras!![SmsRetriever.EXTRA_STATUS] as Status?
when (status?.statusCode) {
CommonStatusCodes.SUCCESS -> {
val message: String? = extras[SmsRetriever.EXTRA_SMS_MESSAGE] as String?
Toast.makeText(context, message, Toast.LENGTH_SHORT).show()
}
CommonStatusCodes.TIMEOUT -> {
Toast.makeText(context, "Timeout", Toast.LENGTH_SHORT).show()
}
}
}
}
}
and my manifest file -

I can't seem to get any information from my broadcast receiver, eventhough the toast message of the sms retriever does say Successfully added retriever
I think I am missing the connection between the fragment and the broadcast receiver but I am not sure - does anyone have an idea what I am missing?

You could try to pass some onOtpReceived function into your OtpBroadcastReceiver and see if that helps.
class OtpBroadcastReceiver(onOtpReceived: (String) -> Unit, onOtpTimeout: () -> Unit) : BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent) {
if (SmsRetriever.SMS_RETRIEVED_ACTION == intent.action) {
val extras = intent.extras
val status: Status? = extras!![SmsRetriever.EXTRA_STATUS] as Status?
when (status?.statusCode) {
CommonStatusCodes.SUCCESS -> {
val message: String? = extras[SmsRetriever.EXTRA_SMS_MESSAGE] as String?
onOtpReceived(message)
}
CommonStatusCodes.TIMEOUT -> {
onOtpTimeout()
}
}
}
}
}

Any Help will be very much appreciated
