- Why: This prevents logging potentially sensitive data to Logcat or Firebase. For critical codepaths we rely on a non-null `!!` check anyhow, which will be reported with a crash to Firebase. Now that we have some confidence the app is reliable, I think we can reflect that confidence in our code. - This moves the `loadLibrary` call to the app start, which will surface issues immediately when launching the app and not when trying to connect. This also makes connect very slightly faster. - Finally, `BootShutdownReceiver` is removed since it was essentially a no-op. There are a few ways we can connect on boot, but this isn't a good approach since it would ignore Android's Always-on VPN setting.
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:$ANDROID_HOME/tools/bin -
Make sure the following Rust targets are installed into the correct toolchain.
aarch64-linux-android arm-linux-androideabi armv7-linux-androideabi i686-linux-android x86_64-linux-androidEnsure you've activated the correct toolchain version for your local environment with
rustup default <toolchain>(find this from the root/rust/rust-toolchain.tomlfile), then run:rustup target add aarch64-linux-android arm-linux-androideabi armv7-linux-androideabi i686-linux-android x86_64-linux-android -
Perform a test build:
./gradlew assembleDebug.
Release Setup
We release from GitHub CI, so this shouldn't be necessary. But if you're looking
to test the release variant locally:
- Download the keystore from 1Pass and save to
app/.signing/keystore.jksdir. - Download firebase credentials from 1Pass and save to
app/.signing/firebase.json - Now you can execute the
*Releasetasks with:
export KEYSTORE_PATH="$(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
