Sign in failing for android

 Right now it's just a webview wrapper around the web application, but in the future it may
 contain native code as well.
 
+/!\ This is still a work in progress, as google sign in does not work yet. Most of the issue is that Google doesn't allow to sign in inside the webview for security reasons. 
+
+We could sign in in a browser with signInWithRedirect and then redirect to the webview, but I haven't found a way to make it come back to the app and store the token. 
+
+We could also use a native sign in with SocialLogin, but it only runs on local assets, not on the webview that loads the remote sign-in page. So one way would be to force the webview to load the local assets, but it's not a clean solution and I haven't found a way to do it yet.
+
+Third solution is to implement a native app, not using webview, in React Native.
+
+If you can make it work, please contribute!

 This document describes how to:
 1. Build and run the web frontend and backend locally  
 2. Sync and build the Android WebView wrapper
