feat: Capacitor v3 configuration file: Add version and android-versionCode fields

Feature Request

Description

While Capacitor tries to avoid changes to users’ native projects, I’ve seen this requested by the community several times and it’s a feature Cordova has. A lot of configuration details (like setting permission details or choosing an App’s name) are set once, so manual project changes aren’t a big deal. However, each time you ship an update to a native iOS/Android app in the app stores, the Version Number must be incremented. So, having “cap sync” update the version number (found in Cap config) in each native project would be a nice workflow improvement.

Current workflow (app is on version 1.0 for example):

• Finish new feature
• Submit to app stores (manually or via Appflow’s Deploy to app stores feature)
• It fails, due to version number not incremented
• Manually open Xcode and Android Studio, increment version number to v1.1.
• repackage binary, resubmit to app stores

Platform(s)

ios, android

Preferred Solution

Supported fields could look something like:

// capacitor.config.json
{ 
  version: "1.2.5", 
  android-versionCode: "3"
}

New workflow:

• Feature complete
• Increment version number in capacitor.config.json.
• npx cap sync to update native android/ios projects with new version number and code
• profit (deploy to app stores)

Alternatives

Update android/ios projects manually.

Hi guys, I recommend also Capacitor Project API and Configuration Tool from ionic-team.

I do this there:

import groovy.json.JsonSlurper

def jsonSlurper = new JsonSlurper()
def packageJson = jsonSlurper.parseText( file('../package.json').text)

ext {
    minSdkVersion = 23
    compileSdkVersion = 29
    ...
    ...
    cordovaAndroidVersion =  '7.0.0'
    appVersionCode = packageJson["versionCode"]
    appVersionName = packageJson["version"]
}

and my Android app version is central in my package.json and so is my global app version. In that way is easier to track version changes globally.

That is what I wanted to offer as PR maybe in capacitor.json instead of package.json (although I find package.json more central).
