This increases our app bundle size with no real benefit. ~~I'm also encountering an issue where the `x86` shared library is being loaded instead of the appropriate x86_64 one, causing a crash.~~ Edit: The crash appears to be coming from somewhere else, still investigating. Still it would be good to remove this as the Rust dependency in the Android build is built serially.
Firezone Android client
This README contains instructions for building and testing the Android client locally.
Dev Setup
-
Install your JDK 17 of choice. We recommend just updating your CLI environment to use the JDK bundled in Android Studio to ensure you're using the same JDK on the CLI as Android Studio.
-
Install the Android SDK through Android Studio.
- Open Android studio, go to Android Studio > Preferences
- Search for
sdk - Find the
Android SDKnav item underSystem Settingsand select - Click the
Editbutton next to theAndroid SDK Locationfield - Follow the steps presented to install Android SDK
-
Install
NDKusing Android StudioTo see which version is installed, make sure to select the
Show Package Detailscheckbox in theAndroid SDKsettings page in Android StudioMake sure the correct NDK version is installed by looking at:
../../rust/connlib/clients/android/connlib/build.gradle.kts -
Set the following ENV variables in the start up config for your shell:
JAVA_HOME=/Applications/Android\ Studio.app/Contents/jbr/Contents/Home ANDROID_HOME=/Users/<username>/Library/Android/sdk NDK_HOME=$ANDROID_HOME/ndk-bundle PATH=$PATH:$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$ANDROID_HOME/tools/bin -
Make sure the following Rust targets are installed into the correct toolchain.
aarch64-linux-android arm-linux-androideabi armv7-linux-androideabi x86_64-linux-androidEnsure you've activated the correct toolchain version for your local environment with
rustup default <toolchain>(find this from the root/rust/rust-toolchain.tomlfile), then run:rustup target add aarch64-linux-android arm-linux-androideabi armv7-linux-androideabi x86_64-linux-android -
Perform a test build:
./gradlew assembleDebug. -
Add your debug signing key's SHA256 fingerprint to the portal's
assetlinks.jsonfile. This is required for the App Links to successfully intercept the Auth redirect../gradlew signingReport
Release Setup
We release from GitHub CI, so this shouldn't be necessary. But if you're looking
to test the release variant locally:
- Download the keystore from 1Pass and save to
app/.signing/keystore.jksdir. - Download firebase credentials from 1Pass and save to
app/.signing/firebase.json - Now you can execute the
*Releasetasks with:
export KEYSTORE_PATH="$(pwd)/app/.signing/keystore.jks"
export FIREBASE_CREDENTIALS_PATH="$(pwd)/app/.signing/firebase.json"
HISTCONTROL=ignorespace # prevents saving the next line in shell history
KEYSTORE_PASSWORD='keystore_password' KEYSTORE_KEY_PASSWORD='keystore_key_password' ./gradlew assembleRelease
