I have a Vue.js web app and custom Android App (I have the source code of both).
I need that the Vue.js web app is able to read a JSON file produced by the custom Android App.
Using the filesystem as the technique of exchange data between the 2 applications I tried the Filesystem Access Api (https://web.dev/file-system-access/) but it seems not supported in Chrome on Android: https://caniuse.com/native-filesystem-api
Do I have other technique of exchange data between an Android app and a Web app without using the internet connection? (no API/FTP). Something like a local storage
Thanks
If you can store the JSON file somewhere on disk of the Android device, you can use a regular
<input type="file">element to upload the file to your Vue app. The File System Access API is not currently supported on Android, as you have noted.
