Answer 1

Use this--

 Intent intent = new Intent(Activity3.this, FinishActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
 Intent.FLAG_ACTIVITY_NEW_TASK);
 intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
 startActivity(intent);
 finish();

Edited--New Answer and would work perfectly..

just taking an example...do it accordingly what your project needs--

I am taking three Activity class A, B and C..and I have applied a close button on the view of class C Activity. If you want then by the Back button you can go to the previous Activity and when you press the close button then you would exit from apps..have a look--

public class AActivity extends Activity {

  /** Called when the activity is first created. */
  @Override
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Intent i = new Intent(this, B.class);
    startActivityForResult(i, 1);
}

@Override
protected void onActivityResult(final int requestCode,
        final int resultCode, final Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (resultCode == 5) {
        finish();
    }
}
}

Take next class activity--

   public class B extends Activity {
    /** Called when the activity is first created. */
   @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.b);

    Intent i = new Intent(this, C.class);
    startActivityForResult(i, 2);
}

@Override
protected void onActivityResult(final int requestCode,
        final int resultCode, final Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (resultCode == 5) {
        setResult(5);
        finish();
    }
}
}

Take last activity--

    public class C extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.c);
}

    // close button..set by xml view..you can set it by button listener.
public void close(View v) {
    setResult(5);
    finish();
}
}

Hopefully, it would solve your problem..cheers!
