I want to get this value from arduino and change the textview in my android. So it will be something like if (xxx == "11"){ textview.setBackgroundColor(Color.RED);} but I don't know how to write/how to get the arduino value and declare in android.

You'll need a HC-05 bluetooth module for example, and the use of the Serial library. Try to define a new serial port and then send your data by it. Arduino code :

SoftwareSerial btSerial (12, 13); //TX sur 12 et RX sur 13
btSerial.begin(9600);
btSerial.println("Link Started !");
