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

Inizia con l’archivio allegato Archive_2.zip e riproduci il crash su un dispositivo Android fisico navigando, usando la riproduzione o la registrazione, tornando indietro e navigando di nuovo. Confronta il comportamento di Android con lo scenario iOS dichiarato funzionante; il lavoro è completato quando il servizio non va più in crash dopo questo ciclo di navigazione.
