Firebase notification not launching (or launching with delay) app

I'm sending a push notification from Firebase console to my Android App. But sometimes, after receiving the notification and waiting for a couple of hours, and clicking the notification thereafter, it is not opening the app.
PS: In Samsung devices app is opening after a delay of 30+ seconds but in other devices like Mi or Oneplus, it is not opening at all.

How do I do fullScreenIntent from FirebaseMessagingService

I'm trying to show a full-screen activity on the lock screen when the app recieves a firebase cloud message.
Currently the code looks like this:
private void showFullScreenIntent(RemoteMessage remoteMessage, String ticketNumber) {
try {
int acceptCallRequestCode = 0;
String channelId = getString(R.string.channel_id);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_action_name)
.setContentTitle("Incoming Video Conference Call")
.setContentText("From Demo Doctor")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_CALL)
.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL)
.setFullScreenIntent(createAcceptCallIntent(remoteMessage, acceptCallRequestCode), true);
// notificationId is a unique int for each notification that you must define
int notificationId = GlobalState.getInstance().getNewNotificationId();
Log.d(TAG, "showFullScreenIntent NotificationId: " + notificationId);
//https://developer.android.com/training/notify-user/time-sensitive
// Provide a unique integer for the "notificationId" of each notification.
startForeground(notificationId, builder.build());
Log.d(TAG, "Finished showFullScreenIntent");
} catch (Exception e) {
Log.d(TAG, e.getMessage());
}
}
private PendingIntent createAcceptCallIntent(RemoteMessage remoteMessage, int requestCode) {
// Create an explicit intent for an Activity in your app
Intent i = new Intent(getBaseContext(), MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
i.putExtra(EXTRA_MESSAGE, remoteMessage);
//Create hashmap of extra stuff
HashMap<String, String> map = new HashMap<String, String>();
map.put(LAUNCH_METHOD, "notification");
i.putExtra(EXTRA_MAP, map);
PendingIntent pendingIntent = PendingIntent.getActivity(this, requestCode, i, PendingIntent.FLAG_CANCEL_CURRENT);
return pendingIntent;
}
The logs show that there are no errors and I can see that Finished showFullScreenIntent gets output to the log. Also the notification id is greater than zero.
My manifest looks like this:

Why don't my Android BroadcastReceiver messages arrive?

This is yet another question about why a BroadcastReceiver doesn't see the messages being sent to it. I've looked at a dozen examples and other questions their solutions seem the same as mine but mine doesn't work.
My receiver is in a service. Here's the manifest fragment:
<service android:name="com.madurasoftware.vmnotifications.services.BLEService"
android:label="BluetoothService"
android:process="com.madurasoftware.vmnotifications.services.VMServices">
</service>
The service registers the receiver like this:
private val messageReceiver = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
Log.d(TAG, "onReceive() called")
val message = intent.getStringExtra(BluetoothService.MESSAGE)
NotificationQueue.add(message)
}
}
override fun onCreate() {
super.onCreate()
Log.d(TAG, "onCreate() called")
val filter = IntentFilter()
filter.addAction(BluetoothService.MESSAGE_ACTION)
baseContext.registerReceiver(this.messageReceiver, filter )
}
override fun onDestroy() {
baseContext.unregisterReceiver(this.messageReceiver)
}
Because I am dynamically registering the receiver I don't add anything about it to the manifest.
I send from a button in my MainActivity like this:
Intent().also { intent ->
intent.setAction(BluetoothService.MESSAGE_ACTION)
intent.putExtra(BluetoothService.MESSAGE, "xyz")
sendBroadcast(intent)
}
Log.d(TAG, "sendBroadcast() called")
When I press the button I see that the logged sendBroadcast() message shows up, but the onReceive() log message does not. So it isn't being delivered.
Can anyone see why?
I'm using API 29 and this is my full manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.madurasoftware.vmnotifications">

App with BroadcastReceiver crashes when triggered on boot

I'm trying to start a service in my app when the phone on which the app is running, boots. I've added a broadcastreceiver, added an intent-filter in the manifest, created a service and added that to the manifest as well. But whenever I boot my phone, after a while it displays that my app has crashed.
An important thing to note is that the service works if it started from MainActivity.
I've seen more questions about this on Stackoverflow, but none of these solve my problem because most of them were of people who forgot to add the receiver to the manifest or something else.
But I don't know how to read logcat-output as well, from when a phone starts, so I can't determine what's crashing the app.

}
override fun onDestroy() {
Log.d(LOG_TAG, "onDestroy of service called")
super.onDestroy()
}
checkMessages() is just a function that calls an API and deserializes it to check if a notification has to be send.
I hope one of you can help me.

For any future viewers: The problem was that I had to use startForegroundService() instead of startService() because I was running it on Android Oreo.
Thanks #Pawel

app was closed JobService not running periodically

I have a Jobservice that runs periodically every time.My activity only is to job start for running on the app.i can stop or destroy the app manually using UI and the JobService not running ,the jobservice why stop i don't know.i attached the my manifistfile and Jobdispatcher what i do something else?
dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(getActivity()));
Bundle myExtrasBundle = new Bundle();
myExtrasBundle.putString("some_key", "some_value");
if (myJob == null) {
myJob = dispatcher.newJobBuilder()
// the JobService that will be called
.setService(ReminderService.class)
// uniquely identifies the job
.setTag("my-unique-tag")
// one-off job
.setRecurring(true)
// don't persist past a device reboot
.setLifetime(Lifetime.FOREVER)
// start between 0 and 60 seconds from now
.setTrigger(Trigger.executionWindow(0, 60))
// don't overwrite an existing job with the same tag
.setReplaceCurrent(true)
// retry with exponential backoff
.setRetryStrategy(RetryStrategy.DEFAULT_LINEAR)
// constraints that need to be satisfied for the job to run
.setConstraints(
// only run on an unmetered network
Constraint.ON_ANY_NETWORK
)
.setExtras(myExtrasBundle)
.build();

On your Job service return true on onStartJob
override fun onStartJob(jobParameters: JobParameters): Boolean {
return true
}
also override onStartCommand like this
override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
return Service.START_STICKY
}
and for menifest write code like this
<service
android:name=".JobServiceEx"
android:permission="android.permission.BIND_JOB_SERVICE"/>
Your service will look like this for Kolin code
class JobServiceEx : JobService() {
var startTime: Long = 0
val workHandler = Handler()
var workRunnable: Runnable? = null
// Called by the Android system when it's time to run the job
override fun onStartJob(jobParameters: JobParameters): Boolean {
Log.d(TAG, "Job started!")
workRunnable = object : Runnable {
override fun run() {
val millis = System.currentTimeMillis() - startTime
var seconds = (millis / 1000).toInt()
val minutes = seconds / 60
seconds %= 60
var curTime = "$seconds"
Toast.makeText(baseContext, "Current Sec : $curTime", Toast.LENGTH_SHORT).show()
Log.e("TAG", "Current Time : $curTime")
workHandler.postDelayed(this, 1000)
}
}
workHandler.post(workRunnable)
return true
}
override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
return Service.START_STICKY
}
// Called if the job was cancelled before being finished
override fun onStopJob(jobParameters: JobParameters): Boolean {
workHandler.removeCallbacks(workRunnable);
return false
}
companion object {
private val TAG = JobServiceEx::class.java.simpleName
}
}
and start and stop service like this
R.id.buttonStart -> {
/**
* start job service to test
*/
var componentName = ComponentName(this, JobServiceEx::class.java)
var jobInfo: JobInfo? = null
jobInfo = JobInfo.Builder(JOB_ID, componentName)
.setRequiresCharging(true)
.setMinimumLatency(1)
.setOverrideDeadline(1)
.build()
var jobScheduler = getSystemService(JOB_SCHEDULER_SERVICE) as JobScheduler
var resultCode = jobScheduler.schedule(jobInfo);
if (resultCode == JobScheduler.RESULT_SUCCESS) {
Log.e("TAG", "Job scheduled!");
} else {
Log.e("TAG", "Job not scheduled");
}
}
R.id.buttonStop -> {
/**
* stop job service to test
*/
val jobScheduler = getSystemService(Context.JOB_SCHEDULER_SERVICE) as JobScheduler
jobScheduler.cancel(JOB_ID)
}
