Retrieve the device's unique IMEI number and transmit it via WebView to a specified website

I am developing an Android application that utilizes a webview to display my web app. I have a specific requirement to retrieve the device's IMEI as soon as the application opens, and then send it via JavaScript from MainActivity.java (through the webview) to my remote web app hosted on a server.

Within the web app, there is a hidden input field where I intend to store the IMEI value. How can I achieve this? Is there a method to pass the IMEI through JS in MainActivity.java and access it in the HTML file?

Answer №1

To address this issue, consider establishing a web server within the mobile application to support an IMEI request API. Essentially, create a basic web server specific to the app on your website. When detecting if the request originates from your app, pass a GET variable to your site for identification purposes. Subsequently, trigger the execution of code that attempts to initiate an AJAX request to the local IP/port of the Android device using JavaScript. This customized request can then be submitted to the specified URL. Given that JavaScript runs locally on a phone, it possesses the capability to perform a web request in its immediate environment.
