Android Bluetooth App

Hi i am kind of new to android development and have recently started working with bluetooth API. I was able to connect my phone to the HC-06 connected to my Arduino NANO. However, I am unable to transfer data correctly. My goal is to grab the current value from the device and store it in a variable in the application, and also display it. Here is my code for both arduino and app.

Android Studio

package com.clipius.clipiusweight;

public class MainActivity extends AppCompatActivity {

    TextView myLabel;
    TextView dataLabel;
    EditText myTextbox;
    BluetoothAdapter mBluetoothAdapter;
    BluetoothSocket mmSocket;

    int readBufferPosition;
    int counter;
    volatile boolean stopWorker;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button openButton = (Button)findViewById(R.id.getDataB);
        Button sendButton = (Button)findViewById(R.id.sendDataB);
        //Button closeButton = (Button)findViewById(R.id.close);
        myLabel = (TextView)findViewById(R.id.ConnectionCheck);
        dataLabel = (TextView) findViewById(R.id.weightValueText);
        //myTextbox = (EditText)findViewById(R.id.weightValueText);

        //Open Button
        openButton.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View v)
            {
                try
                {

        }

        if(!mBluetoothAdapter.isEnabled())
        {
            Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enableBluetooth, 0);
        }
