I'm setting up a new service for Android and I'm using JobIntentService for the first time. The service includes also a notification which is not displayed when I'm running the app in an Android version below Oreo. The job itself works until the end.
This is the code I've tried that works perfectly fine for API >= 26.
private void initializeNotification (String fileName) {
intent = new Intent(this, UploadActivity.class);
intent.putExtra("file_name", fileName);
intent.putExtra("file_list", (Serializable) auxList);
pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
long[] vibratePattern = {0L};
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
NotificationChannel notificationChannel = new NotificationChannel(MyConstants.NOTIFICATION_CHANNEL_ID, "Upload", NotificationManager.IMPORTANCE_DEFAULT);
notificationChannel.setVibrationPattern(vibratePattern);
notificationChannel.enableVibration(true);
notificationManager = getSystemService(NotificationManager.class);
}
notification = new NotificationCompat.Builder(this, MyConstants.NOTIFICATION_CHANNEL_ID)
.setSmallIcon(R.drawable.icon)
.setColor(getResources().getColor(R.color.primary))
.setContentText(fileName)
.setPriority(PRIORITY_DEFAULT)
.setProgress(PROGRESSBAR_MAX, 0, false)
.setContentIntent(pendingIntent)
.setVibrate(vibratePattern)
.setStyle(new NotificationCompat.BigTextStyle().bigText(fileName))
.setAutoCancel(false);
notificationManager.notify(NOTIFICATION_ID, notification.build());
My gradle file looks like this:
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
applicationId "es.app.services"
minSdkVersion 19
targetSdkVersion 28
versionCode 12
versionName "1"
// Enabling multidex support.
multiDexEnabled true
I've also added this library in the gradle file:
implementation "com.android.support:support-compat:28.0.0"
And this permissions in the manifest file:
<uses-permission android:name="android.permission.WAKE_LOCK" />
<service android:name=".services.UploadJobIntentService"
android:permission="android.permission.BIND_JOB_SERVICE"/>
I'm getting this warning in the console.

I think you have to handle this by broadcast receiver, using job Intent service directly with Apis before 28 make performance overhead.
By the way this Demo will help you in your issue. https://github.com/Ahabdelhak/Service_AlarmManager_Broadcast_Notification
