By now, we have a basic vuejs app which can fetch data from a WordPress API using axios and can display the data.
The aim of this series, however is to build an app and get it on the app stores. To achieve this, we are going to use cordova. Cordova is a fantastic framework which allows you to package web apps and transform them into actual apps to run on devices.

Following this guide I made previously, we will set up our vuejs app to work with cordova: https://jonathansblog.co.uk/adding-cordova-to-an-existing-vue-app

npm install -g cordova
cd ~/git/my-cool-app
vue add cordova

Next, follow the cordova wizard (it will show when you do vue add cordova):
> Name of folder where cordova should be installed – src-cordova
> Select Platforms: Android, iOS, Browser

To run your new cordova app:

npm run cordova-serve-browser

(urls must be ‘hash’ ones, eg /my-homepage becomes /#/my-homepage)

Next, you can do all the building and testing, using these commands

npm run cordova-serve-android # Development Android
npm run cordova-build-android # Build Android
npm run cordova-serve-ios # Development IOS
npm run cordova-build-ios # Build IOS
npm run cordova-serve-browser # Development Browser
npm run cordova-build-browser # Build Browser
npm run cordova-prepare # prepare for build

Install android system – build android apps

https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html

  • Install jdk8 (create account at oracle, verify email, login and download)
  • Install gradle (brew install gradle – https://gradle.org/install/)
  • Install android studio (and pick an skd – https://developer.android.com/studio/install)
  • install android SDK (api level 28) – create a new project (a blank one) click on the sdk manager icon – top right (its not in tools > skd manager!)
  • install android avd (api level 28) – create a new project (a blank one) click on the sdk manager icon – top right (its not in tools > avd manager!)

Once you have all this, you can emulate and build for the android platform

npm run cordova-build-android

sign:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/git/my-cool-app/src-cordova/keys/my-release-key.keystore app.apk alias_name

zipalign:

find ~/Library/Android/sdk/build-tools -name "zipalign"~/Library/Android/sdk/build-tools/29.0.0/zipalign -v 4 Project1.apk Project1-aligned.apk

You can then use the apk for testingTo upload into google play store, you need to send an aab. You’ll need to open your code in android studio to do that build:
open android studio
build > generate signed bundle (dont think this actually signs it though)
** have to upload aab format
