Setup

First setup your react-native platform.

Android

Follow the official [Facebook] (https://facebook.github.io/react-native/docs/0.58/getting-started.html) doc. Make sure you use Google APIs Intel x86 Atom System Image for your simulator for 0.58.

Not covered above, but you will also need to install gradle to build the app for release. I recommend installing with ASDF (Gradle plugin I used for asdf)

npx jetify (which is run as a postInstall script) will no longer be needed once the upgrade to react native 0.60 is done

Troubleshooting

• Sometimes a new emulator will not see the packager. If you've followed the Facebook guide and pulled from the repo recently, try opening the dev menu in your emulator (CMD+M on mac), clicking on Dev Settings, clicking on Debug server host & port for device, and typing in localhost:8081 (or whatever port your metro bundler is running on) as the port.

iOS

Follow the official [Facebook] (https://facebook.github.io/react-native/docs/0.58/getting-started.html) doc for 0.58.

Make sure you are on XCode 10.2

Make sure you run cd ios && pod install

You must install cocoapods if you don't already have them, sudo gem install cocoapods

Fastlane

You must install fastlane if you want to deploy new iOS builds

https://docs.fastlane.tools/getting-started/ios/setup/#rubygems-macoslinuxwindows

Running App

1. yarn
2. [iOS only] cd ios && pod install && cd ..
3. react-native link
4. react-native run-ios or react-native run-android

General Troubleshooting

Luis wrote a small react-native-clean script. Kill your Metro Bundler, run react-native-clean, and run react-native-run-* again to get a fresh, artisinal, hand-crafted, non-GMO, fully vaccinated, grass-fed build.

Sometimes, a JS refresh is not enough to update code, especially if you recently added functionality that utilizes native code.

Also, please run this before merging a new branch to ensure that your changes still result in a clean build. Slack him if you need it.

Deloyment (Fastlane)

Pushing new builds

IOS fastlane ios beta for new Testflight build

For new apple App Store build, open ios/info.plist. Increment the field CFBundleShortVersionString and CFBundleVersion

ANDROID

1. Open /android/app/build.gradle and manually increment the versionCode field.
2. fastlane android beta for new Android build. (Alternatively, cd android && gradle clean assembleRelease)
3. Go into android/app/build/outputs/apk/release, rename the APK to Mood.dev.apk and upload it to Google Drive. Rename the same APK to Mood.apk, log into Play Console, and use it to create a new release there.

Generating Screenshots

For iOS In the root dir, fastlane snapshot cd fastlane/ios_screenshots fastlane frameit black cd .. fastlane deliver

For Android Go to https://developer.android.com/distribute/marketing-tools/device-art-generator Drag each screenshot over to the Pixel 2 icon Save image as

TODO: Find a way to automate these with fastlane screengrab + an imagemagick script? similar to what frameit does but for android
