Notification is NOT displayed on the Notification Bar when App is on the foreground - Android

[Bilal-Abdeen]

Your effort and time to help are highly appreciated.

Scenario 1 (Problem):

• application is on the screen
• the notification icon does NOT appear at all on the "Notification Bar"
• the event registerNotificationReceivedForeground is fired correctly
• obviously, I cannot open the notification because there is nothing on the screen to click on.

Scenario 2 (OK):

• application is on the screen
• I click the Home button, so the application disappears from the screen
• the notification icon does appear CORRECTLY on the "Notification Bar"
• the event registerNotificationReceivedForeground is fired correctly (NOT registerNotificationReceivedBackground)
• the event registerNotificationOpened is fired correctly

I tried adding some sections to AndroidManifest.xml as described in the following post. However, this did NOT seem to work. Your effort and time to help are highly appreciated.

Actually, I found the solution in another issue #525. Sorry, I could not understand the resolution, which was suggested in that issue, before creating this issue.
