I am very new with android studio, as in, my second week! Please explain this to me and guide me to a solution? I cannot run my tablet intended application! Again, I am novice and want to learn the solution. Thank you in advance for any help or suggestions that you may have!The app should look like this if it helps? I am willing to provide any other details that are needed to clarify the situation!
