I already have a website which I want to convert it to an apk by adding a WebViewer and customizing it. the problem is here: I have an input in my website which is used by users to upload their files. but this input is not functioning in my apk. when the users click on it, it does not show any action.
Can you please guide me about how to solve this issue?
Thanks a lot in advance

Yes, You may be right.
To end this discussion, today I found another solution to solve my problem which is “https://median.co/” website. by using this website, I could convert my website to an APK, in such a way that all my input files work properly.
