Building Firefox for Android¶
First, you’ll want to set up your machine to build Firefox. Follow the instructions there, choosing “GeckoView/Firefox for Android” as the bootstrap option.
Once you’re set up and have a GeckoView build from the above, please continue with the following steps.
1. Clone the repository and initial setup¶
git clone https://github.com/mozilla-mobile/firefox-android
cd firefox-android/fenix
echo dependencySubstitutions.geckoviewTopsrcdir=/path/to/mozilla-central > local.properties
replace /path/to/mozilla-central with the location of your mozilla-central/mozilla-unified source tree.
2. Build¶
export JAVA_HOME=$HOME/.mozbuild/jdk/jdk-17.0.6+10
export ANDROID_HOME=$HOME/.mozbuild/android-sdk-<os_name>
./gradlew clean app:assembleDebug
<os_name> is either linux, macosx or windows depending on the OS you’re building from.
For more details, check out the more complete documentation.
3. Run¶
From the gecko working directory:
./mach android-emulator
From the firefox-android working directory:
./gradlew :app:installFenixDebug
"$ANDROID_HOME/platform-tools/adb" shell am start -n org.mozilla.fenix.debug/org.mozilla.fenix.debug.App
