How to install Android Studio and android core based VITULUS app on Ubuntu 20.04
The application can control the device on the robot, display the battery and charging status, manage and navigate in maps and control the robot using a joystick. For a better idea of what the application looks like, let's start with two printscreens.
If you want to change or improve VITULUS android app, you must install and configure Android studio and android_core environment. Then you'll be able to modify VITULUS app for your needs.
First install OpenJDK
sudo apt-get install openjdk-8-jdk
Then download Android Studio
Extract the archive to /opt/android-studio
tar -xzvf android-studio-ide-201.6858069-linux.tar.gz --directory /opt/
Run the Android studio
Choose SDK Manager
And add API levels 17, 15, 13, 10
On the welcome screen select "Get from version control"
Put the git url.
And confirm by Clone button.
Now is everything ready. The Android Studio offer update of Graddle plugin, don't do that.
The VITULUS application is called android_vitulus_control and is based on android_core. Now you can modify it or expand it according to your own needs. It is not perfect and will certainly change and develop in the future, but it is functional. Currently, this project is built on a non ROS java environment, so custom message types are not available. It uses only those that are available from the repository. This will need to change over time.
