How to fix Android Studio installation and Gradle errors?

I have installed Android Studio with the idea of developing applications with Cordova and Phonegap thanks to the help of my partner @karel who showed me this question: How to install Android Studio on Ubuntu? I followed the instructions exactly, but even so I have several errors. When you start Android Studio with the following command, sudo -E /opt/google/android-studio/bin/studio.sh this shows the first error:

Gtk-Message: 09:07:14.283: Failed to load module "canberra-gtk-module"

(java:13968): IBUS-WARNING **: 09:07:14.566: 
The owner of /home/miguel/.config/ibus/bus is not root!

I installed the SDK, (I think I installed the necessary ones) and when I returned to a Cordova project, and I ran cordova requirements to see if everything was OK, the result was the following:

Android Studio project detected

Requirements check results for android:
Java JDK: installed 11.0.2
Android SDK: installed true

What did I do wrong? What can I do to correct this and be able to run my applications on Cordova and Phonegap?
