try this:

@Override  
 public void onCreate(Bundle savedInstanceState) {  
 super.onCreate(savedInstanceState);  
 setContentView(R.layout.main);    
 Bundle bundle = this.getIntent().getExtras();   
if (bundle != null)
{       
 String fromAdd = bundle.getString("from");  
 String msgBody = bundle.getString("body");   
}         
}

in Android Bundle we put key value pair, and it is mandatory that you pass same key, while getting data from bundle, which you are putting data. check your code you are putting two string on intent, which are: "from", and "msg" and you are getting values from intent by key: "from" and "body"

so change it either in starting activity or Activity 2. so that key values would match.

Try this.....

Activity1.java

Intent intent = new Intent(getApplication(),Activity2.class);
intent.putExtra("from",from);
intent.putExtra("Body",Body);
StartActivity(intent);

Activity2.java

Intent intent = getintent();
Bundle bundle=intent.getExtras();
String Body=bundle.getString("Body");
String From=bundle.getString("From");
setResult("RESULT_OK",intent);

Bundle bu=getIntent().getExtras();

String title=bu.get("from").toString();

String msg=bu.get("body").toString();

Try this..... to pass value from Activity1 to Activity2.

    Intent myIntent = new Intent(Activity1.this, Activity2.class);
           myIntent.putExtra("UserId",UserId);
           myIntent.putExtra("UserName",UserName);
           myIntent.putExtra("CompanyID",CompanyID);
           myIntent.putExtra("CompanyName",CompanyName);
           myIntent.putExtra("ProjectId",ProjectId);
           startActivity(myIntent);

Also can extract the value you can use

    Intent intent = getIntent();
    UserId=intent.getStringExtra("UserId");
    UserName=intent.getStringExtra("UserName");
    CompanyID=intent.getStringExtra("CompanyID");
    CompanyName=intent.getStringExtra("CompanyName");

pass values from one activity to another
