Here you can find the android application that uses the You Have Mail shared service code.
This app has been specifically designed to work in cases where Google Play services are not available. The App launches a Foreground Service that polls the accounts every 15 seconds. Once an account reports a new message has arrived it will create a notification.
When the App knows about which backend maps to which Android application, it will try to launch that app if the user clicks on the application.
The Application is only available for x86_64 and Aarch64 and is has API 29 as minimum requirements. It has been tested on a Pixel 3a running the last compatible version of Graphene OS.
Session tokens are stored using the EncryptedSharedPreferences API.
This application is built in Android Studio. It uses Rust programming language.
In order to build and run this application in Android Studio install Rust in your environment.
Below commands are for Linux Debian/Ubuntu:
sudo apt-get install -y python-is-python3 golang-go;
# Install Rust using official method
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup default stable;
rustup target add armv7-linux-androideabi;
rustup target add aarch64-linux-android;
rustup target add x86_64-linux-android;
Alternatively use suitable docker image with Rust preinstalled instead of manual installation above.
