pls help

try this

Bundle b = getIntent.getExtras();

or

Bundle b = ClassName.this.getIntent.getExtras();

retrieve data like this:

Bundle var_name = getIntent().getExtras().getBundle(key);

If you use a custom Bundle, it seems there is some requirements, according to the doc:
The keys must include a package prefix, for example the app com.android.contacts would use names like "com.android.contacts.ShowAll".
The common way I know to share data between activities is to use the default Intent bundle to store them, like this:

Intent i=new Intent(Cortes.this,Display.class);      
i.putExtra("latitude", lat+"");
i.putExtra("longitude", lon+"");
i.putExtra("address", result1);
startActivity(i);

Then, you retrieve the infos like this:

Intent i=this.getIntent();
latitude=i.getStringExtra("latitude");
longitude=i.getStringExtra("longitude");
address=i.getStringExtra("address");
