Zooniverse Mobile App

The Zooniverse Mobile app is a React Native app that allows folks like you and me to contribute to astronomy, ecology, and anthropology research from their couch, bathtub, or bus stop (but don't swipe and drive, please).

Preparing The React Native Framework

Requirements:

• Node >= 16 (Recommend >= 18)

  Steps:

  1. Follow the instructions for Android and iOS setup in this guide.
  2. Clone down this repo and navigate to its directory (called mobile).
  3. Run npm install (later, if you need to reinstall dependencies for some reason, you can run rm -rf node_modules/ && npm install)
  4. Run npm start.

     Troubleshooting:

iOS

Requirements:

• XCode
• An iPhone X Simulator, which you can run from XCode.
• To run on an iOS device see [Running on device - iOS]https://reactnative.dev/docs/running-on-device?platform=ios

  Steps:

  On the command line, from the mobile directory, run:

  1. cd ios && rm -rf Podfile.lock && pod install && cd ... You may need to brew install cocoapods first.
  2. npm run ios

Android

Requirements:

• Android Studio
• You'll need at least one emulator. To get one:
  • Within Android Studio, open the "AVD Manager" - in the toolbar click the icon with the purple device and small android (fourth from the right)
  • Click 'Create Virtual Device' - bottom left-hand corner
  • Create at least one using the latest Android Release. I have a few different size and Android Release configurations
• You can also use an Android device that is plugged into your computer. Run adb devices and confirm you see your device listed. If not use [Running on device - android]https://reactnative.dev/docs/running-on-device?platform=android for troubleshooting
• Also you'll need a Gradle properties file outside the project for keeping secrets that aren't checked into source control. This should be in ~/.gradle/gradle.properties and contain the following:

  MYAPP_RELEASE_STORE_FILE=/path/to/your/keystore.jks
  MYAPP_RELEASE_KEY_ALIAS=android
  MYAPP_RELEASE_STORE_PASSWORD=android
  MYAPP_RELEASE_KEY_PASSWORD=**you can find this in passbolt**

You will have to get the key itself from an existing maintainer. We are looking for a way to securely store this so you can get it without worrying about corruption. You don't need it to build for debugging—only for release to the Play Store.

Steps:

1. To run in the emulator from the command line (you'll need device connected or emulator already running): npm run android. Shortly, your emulator should boot with the Zooniverse app on it.
   • You need to have either a device emulator open already or a physical device plugged into your computer. Otherwise, you'll need to run through Android Studio
   • If Android studio prompts you to update Gradle files, you should do it.
   • The command react-native run-android will install the build, but fail in launching the app due to a bug with the react-native script with having a separate applicationId for development builds.

If you Work for The Zooniverse

You may also want to set up error reporting from your local copy of the application to our reporting service, Sentry. Here are instructions on how to do that!

Tools:

This project is setup with Reactotron. Learn more here. Reactotron is useful for:

1. Inspecting network requestsl.
2. As an alternative for console.log (Separates the logs for each device/simulator being used). In order to use with an android device/emulator you must run adb reverse tcp:9090 tcp:9090 before running the project.
