hi i'm a new android app beginner.i was wondering if anyone could help me to solve the issue here:

public class MainActivity extends Activity  {

BluetoothAdapter adapter = null;
    BTClient _bt;
    ZephyrProtocol _protocol;
    NewConnectedListener _NConnListener;
    private final int HEART_RATE = 0x100;

        super.onCreate(savedInstanceState);

        /*Sending a message to android that we are going to initiate a pairing request*/
        IntentFilter filter = new IntentFilter("android.bluetooth.device.action.PAIRING_REQUEST");
        /*Registering a new BTBroadcast receiver from the Main Activity context with pairing request event*/
       this.getApplicationContext().registerReceiver(new BTBroadcastReceiver(), filter);
        // Registering the BTBondReceiver in the application that the status of the receiver has changed to Paired
        IntentFilter filter2 = new IntentFilter("android.bluetooth.device.action.BOND_STATE_CHANGED");
       this.getApplicationContext().registerReceiver(new BTBondReceiver(), filter2);

     //Obtaining the handle to act on the CONNECT button
       TextView tv = (TextView) findViewById(R.id.labelStatusMsg);
        String ErrorText  = "Not Connected to HxM ! !";
         tv.setText(ErrorText);

    }

 };

and the next activity to show the result based on the main:

package com.example.zephyr;

import android.app.Activity;
import android.os.Bundle;

public class Activity2 extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main1);
    }
}

much help is greatly appreciated

some of the parts contains the source code...i just added in some extra code

if anyone could help me to solve the issue here

What issue? You just uploaded large chunk of code that cannot be compiled because resources are missing and you did not mentioned any errors or problems that you are having
