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

}
final Handler Newhandler = new Handler(){

switch (msg.what)
{
case HEART_RATE:
String HeartRatetext = msg.getData().getString("HeartRate");

}
}
};
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
