Current Behavior

I have tried to add Android with the command npx cap add android before updating to capacitor 2. The log shows an error:

✔ Installing android dependencies in 11.46s

After this I run the npx cap open android, and when building from the IDE I get the following error:

See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.

* What went wrong:

FYI this is the dependencies list in package.json file after running npx cap add android:
...
"@capacitor/android": "^2.0.0",
"@capacitor/core": "1.5.0",
...

The CLI is also in version 1.5.0 in the devDependencies list

Expected Behavior

This behavior is fixed when I update to capacitor 2. I guess the issue will appear for those users that add the android platform in version 1.5 of capacitor. After the update, everything is on version 2 and works fine

Sample Code or Sample Application Repo

There's nothing special about the ionic app that I was testing. Just a few simple functionalities

Reproduction Steps

• Create an ionic app with capacitor enabled (the app I am playing around with was created some weeks ago and it is using ionic 5)
• ionic build
• npx cap add android
• npx cap open android

Other Technical Details

npm --version output:
6.9.0
node --version output:
10.16.3

yeah, add was installing latest @capacitor/android, but the template used to create project comes from the CLI, it's been changed to install a version that matches the CLI version, see #2724

Thanks for the issue! This issue is being locked to prevent comments that are not relevant to the original issue. If this is still an issue with the latest version of Capacitor, please create a new issue and ensure the template is fully filled out.
