Creating a build/development environment for the Android App

Build instructions#

If you would like to develop this application we'd love your help! These build instructions are brief and should be improved, please send a PR if you can.

  • Use Android Studio 4.1.2 to build/debug (other versions might work but no promises)
  • Use "git submodule update --init --recursive" to pull in the various submodules we depend on
  • There are a few config files which you'll need to copy from templates included in the project. Run the following commands to do so:
rm ./app/google-services.json
cp ./app/google-services-example.json ./app/google-services.json
rm ./app/src/main/res/values/mapbox-token.xml
cp ./app/special/mapbox-token.xml ./app/src/main/res/values/
rm ./app/src/main/res/values/curfirmwareversion.xml
cp ./app/special/curfirmwareversion.xml ./app/src/main/res/values/
  • (Unfortunately) you need to get a (free) mapbox developer token here and put that token in your user gradle.properties.
~/development/meshtastic/MeshUtil$ cat ~/.gradle/gradle.properties
MAPBOX_DOWNLOADS_TOKEN=sk.yourtokenherexxx
  • Now you should be able to select "Run / Run" in the IDE and it will happily start running on your phoneor the emulator.
note

The emulators don't support bluetooth, so some features can not be used in that environment.

Analytics setup#

  • Analytics are included but can be disabled by the user on the settings screen
  • On dev devices
adb shell setprop debug.firebase.analytics.app com.geeksville.mesh
adb shell setprop log.tag.FirebaseCrashlytics DEBUG

for verbose logging:

adb shell setprop log.tag.FA VERBOSE

Publishing to google play#

  • Only supported if you are a core developer that needs to do releases
