Android Java - Identify an Int.

Hi. I'm looking for someone who can Identify an Int or a Double inside an Android Java Studio Project of Android Studio. I need this Job to be done immediately. You can run the App to help yourself identifying it. It is an App which tells you which note you are playing on the Guitar. What I need you to find, it is the Actual Detected Main Frequency Double or Int. If I would be playing an A (440 Hz), you would have to find the Int or Double which contains that "440" number. . That's all I need for now. The Android Studio Project is attached to this Post. You can download it and open the Project from the "Tuner" folder. . As the final detail, perhaps I will need additional tasks after this one concerning this Project during the next few days. . So, if you are interested, send me a message. Thank you for your time. Have a good day.
