I had some problems when already had an existing platform and removed it. Sometimes u do need to delete the plugins folder in the project and than add the platform again. Do you have some scripts to make sure everything is working with [email protected]? I had to modify some files so all paths are correct.

patch-android-studio-check.js

module.exports = function(context) {
  if (context.opts.cordova.platforms.indexOf('android') < 0) {
    return;
  }

  const path = context.requireCordovaModule('path');
  const androidStudioPath = path.join(context.opts.projectRoot, 'platforms/android/cordova/lib/AndroidStudio');
  const androidStudio = context.requireCordovaModule(androidStudioPath);
  androidStudio.isAndroidStudioProject = function() {  return true; };
};

build-extras.gradle.js

var fs = require('fs');
var path = require('path');

if(fs.existsSync(path.resolve(__dirname, '../platforms/android'))) {
  fs.createReadStream(path.resolve(__dirname, 'build-extras.gradle')).pipe(fs.createWriteStream(path.resolve(__dirname, '../platforms/android/build-extras.gradle')));
}

build-extras.gradle

android { 
    flavorDimensions "default"
}

config.xml

    <platform name="android">
        <hook src="package-hooks/build-extras.gradle.js" type="after_platform_add" />
        <hook src="package-hooks/patch-android-studio-check.js" type="before_plugin_install" />
        <hook src="package-hooks/patch-android-studio-check.js" type="before_plugin_add" />
        <hook src="package-hooks/patch-android-studio-check.js" type="before_build" />
        <hook src="package-hooks/patch-android-studio-check.js" type="before_run" />
        <hook src="package-hooks/patch-android-studio-check.js" type="before_plugin_rm" />
...
