2WD Robot Driving

Hello fellow makers!

I stumeled opon a problem. I tried my best but, the connection with the bluetooth module and the .apk file that they add won't work. If anyone got any ideas, I would be very thankful!

I'm adding also the whole code, but for the control of the car I need to use the RemoteControl .ino file. Also adding the page, where I got the documentaiton.

And here I got the application for the Android device: https://drive.google.com/file/d/0BzxrU4QvH7jEWkpMREF2SnpLUTg/edit

In what way is this an installation problem?
