Answer 1

you can use:

public void onBackPressed()  
{  
    //do whatever you want the 'Back' button to do  
    //as an example the 'Back' button is set to start a new Activity named 'NewActivity'  
    this.startActivity(new Intent(YourActivity.this,NewActivity.class));  

    return;  
}

Try this:

public void onBackPressed() {  
    finish();
    return;  
}

Answer 3

You can override the Back Button key press like so:

@Override
public boolean onKeyUp(int keyCode, KeyEvent msg) {

     switch(keyCode) {
     case(KeyEvent.KEYCODE_BACK):
          Intent a1_intent = new Intent(this, A1Activity.class);
          startActivity(a1_intent);
          finish();
          return true;



     }
     return false;
}
