Answer 1

Make sure you are doing everything correctly: First build on android-studio to check the project. Then go to your terminal and in your project folder enter the android folder:

android cd

After entering, type the following command

./gradlew installDebug

and wait.

Don’t forget to run the application on android-studio earlier.
