I have a PWA and it stores data in the index DB of web browser. Whenever user clears the browser history , the data stored in the browser also get cleared. So i want to store the data in a text file in android internal storage from the browser. So i have included my PWA into Trusted Web Activity. My question is how to store file/data in the android internal storage from the web page shown in the trusted web activity.[calling android function from java script]
i have also included my PWA into Android web view. But Web view does not support background synchronization. So i have started trying with Trusted web activity. I do not want to use Hybrid App like apache cordova to access the android native functionality(storing in internal storage ).
