Describe the bug
I am implementing cognitiveservices for NativeScript android. It's working fine but when I am navigating to another page & come back to previous page that time during use of the service got crash on real device (Samsung s7 edge). It's working fine with emulator but crashing in real device.

To Reproduce
Please check the attached project file. Click on Navigate & play or record. Then back to previous page & click again on Navigate to go. Now check the service & it will crash the APP. Same scenario is working fine with iOS.

Expected behavior
Should work as iOS

Sample project
Archive_2.zip

Beginne mit der angehängten Archive_2.zip und reproduziere den Absturz auf einem physischen Android-Gerät, indem du navigierst, die Wiedergabe oder Aufnahme verwendest, zurückkehrst und erneut navigierst. Vergleiche das Verhalten von Android mit dem beschriebenen funktionierenden iOS-Szenario; als abgeschlossen gilt die Aufgabe, wenn der Dienst nach diesem Navigationszyklus nicht mehr abstürzt.
