Hi all

i want to open another Android application from my application.

for example, when i click on a button, it should open the Messaging application for me, so that i can send SMS.

You can use
startActivity() function .

Intent i =new Intent(this,Display2.class);
startActivity(i);

Here are few links that can help -
First read up on Android How Tos: Opening New Screen
Then take a look at android.content.Intent class to find an Intent that can help launch a messaging application.
You can see all this knowlege being applied in this sample code: Sending Email from Android
