BelgranoWear (app)

This repository is the frontend of the static information provisioning backend located at belgranowear/belgranowear.github.io.

BelgranoWear is an application that lets you travel through the Belgrano Norte network (maintained by Ferrovias).

System requirements

• Android 5.1 or greater
• 32 MB of free storage space
• An internet connection

Development

• Download Expo Go for Android or for iOS.

• Enable the real-time bundler by running the following command:

  ACTION=run docker compose up --build

• In a different terminal, copy and paste the following command to get your IP address:

  ip addr show | grep -e ': w' -e ': e' -A4 | grep inet | sed 's/.*inet //' | cut -d ' ' -f 1

• Open Expo Go and pass a URL as the following example:

  exp://192.168.0.4:8081

  The port will always be 8081.

• Wait for the app to get bundled and accept all permission requests.

• That's it, you're good to go! Any changes done in the source code will update in real time.

Building

Release mode

• Create a keystore

  keytool -genkey -v -keystore release.keystore -alias belgranowear -keyalg RSA -keysize 2048 -validity 10000

• Use GPG to convert the keystore to a variable-safe string

  gpg -c --armor release.keystore

• Copy the output of this command and paste it into an exported variable, i.e.:

  export RELEASE_KEYSTORE="-----BEGIN PGP MESSAGE-----
  
  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
  ...
  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX==
  =XXXX
  -----END PGP MESSAGE-----
  "
  

• Export the passphrase for your keystore as a different variable

  export RELEASE_KEYSTORE_PASSPHRASE=HereGoesYourKeystorePassphrase

• Set up a variable to store the contents of your gradle.properties file. Keep MYAPP_UPLOAD_STORE_FILE and MYAPP_UPLOAD_KEY_ALIAS untouched, just like in this example.

  export GRADLE_PROPERTIES="
  MYAPP_UPLOAD_STORE_FILE=/tmp/keystore
  MYAPP_UPLOAD_KEY_ALIAS=belgranowear
  MYAPP_UPLOAD_STORE_PASSWORD=HereGoesYourKeystorePassphrase
  MYAPP_UPLOAD_KEY_PASSWORD=HereGoesYourKeystorePassphrase
  
  ENABLE_PROGUARD_IN_RELEASE_BUILDS=true
  "
  

• Follow the steps described in the Debug mode section.

Debug mode

• Install docker as explained in the linked guide.

• Clone this repository wherever you want, just make sure you'd have write permission with the user you're currently logged in.

  git clone https://github.com/belgranowear/BelgranoWear

• Change to the created directory by running cd BelgranoWear.

• Run the following command:

  MODE=test docker compose up --build

• That's it, wait for a few minutes and you'll find the output in the artifacts directory.
