package com.android.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello, NEECT!");
setContentView(tv);
}
}

● Intents
- Messages for the system to bind application
components in the same or different application.
- An object holding abstract information
- Intent filters
Initiate a phone call:
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + “234001010”)));
