Technica 2018 Mobile App

This is the the mobile app for Technica's 2018 hackathon.

Quick Start

  1. npm install

  2. react-native link

  3. react-native run-ios or react-native run-android

Setting up notifications on iOS

  1. sudo gem install cocoapods
  • Make sure you have version pod --version outputs 1.5.3 (not 1.4.0)
  1. cd ios && pod install && cd ..

Setting up AWS mobile hub

Because we are using AWS mobile hub in our project you will need to pull the required configuration files to connect to the AWS instance. Once this is set up you will only need to run aws mobile pull when adding new AWS capabilities to the app

  1. Request cli credential access from somebody (either Tal or someone on mobile backend)

  2. Configure aws cli if you haven't already https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html, make sure your credentials are saved in ~/.aws/credentials

  3. Configure awsmobile cli https://docs.aws.amazon.com/aws-mobile/latest/developerguide/aws-mobile-cli-reference.html.

  4. After you run awsmobile configure, it will use your cli credentials to find the technica mobile app project

  5. You will need to run awsmobile init 6308bcc8-4bd7-4214-b5c1-1b1055829818 to connect to the backend

  6. Run awsmobile pull from now on to update the aws-exports.json this file is read by App.js to configure aws capabilities.

Testing notifications (android and iOS)

  1. Log in to the firebase console here

  2. Click 'Cloud Messaging' on the right side if it's not already on that page

  3. Click new message

  4. For target select 'Single device', paste the fcm token spit out by the debugger when the app opens

  5. Enter in a message text

  6. Click Advanced and enter a title

  7. Click send message

  8. Try sending a message while the app is open and once again while app is closed. Both should display the same (you can just duplicate the first message and send it again).

Building the app on Android

  1. In the project root run the command react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

  2. Open up android studio

  3. Click Build -> Generate Signed APK

  4. Click next, then select the keystore path (ask somebody for the technica-release-key.keystore file)

  5. For key alias enter technicasigningkey

  6. For the key and store password enter the key password (ask the same person for the password)

  7. Select destination folder as .../technica-mobile-app/android/app/build/outputs/apk

  8. Select build type release

  9. Select v1 and v2 ignature versions

  10. Select build, the apk will end up in the outputs/apk/release

  11. In the android/app/build.gradle, bump up the version code by 1 and version name by minor / major release order.

  12. Commit this update and upload APK to google play store under releases

Building the app on iOS

  1. Under ios/technica/Info.plist, comment out the following lines:
<key>localhost</key>
<dict>
  <key>NSExceptionAllowsInsecureHTTPLoads</key>
  <true/>
</dict>
  1. Download the release provisioning profile from the apple dev account, double click to load into xcode, it should be called Technica Distribution Provisioning Profile

  2. Under general tab, in the technica target, make sure it is selected under release signing section.

  3. Select generic iOS device under build tager, and Press Command-B to build the app, hope it works

  4. If that succeeds, click Product -> Archive

  5. Once the archive is created, click Window -> Organizer, you should see the archive you just created.

  6. Select the archive and click validate app, leave everything checked, and select the Technica Distribution provisioning profile

  7. If this succeeds, click distribute app to upload it to app store connect.

  8. git checkout ios/technica/Info.plist in order to add the localhost exception back (do this before step 10 since it will modify Info.plist, if you don't do this building on emulator won't work for debug version)

  9. Increment the version and build number under the general tab, then commit the version change (can combine android version bump into one commit).
