Using life cycles in android

I'm a new android programming beginner :) .

I have made a simple app which adding places .

1- Main activity include buttons{Places , Add place , Favorites Places }

so let's assume we are in the "Add place" activity , we type tite and description and add the place to arrayList, and move on to Places which has this list ..

The problem is when I type back, I get back the details I wrote about the place, but I'm trying to clear it when I press back in the phone ...

how can I do this to avoid crashes ?

Thanks all

-- Update : Thanks to all people who reply trying to help me, that's awesome :) I just added : 

@Override
    public void onBackPressed(){
        Intent intent = new Intent(PlacesActivity.this,MainActivity.class);
        startActivity(intent);

    }

This solution was suggested by : Arsen Sench :)

You can use startActivity() from both classes. Or you can use startActivityForResult(). Here is example of using startActivity() from both activites.

From first Activity

Intent i = new Intent(YOURFIRSTACTIVITY.this,YOURSECONDACTIVITY.class);
startactivity(i);
finish();

From Second Activity

@Override
public void onBackPressed()
{
    Intent i = new Intent(YOURSECONDACTIVITY.this,YOURFIRSTACTIVITY.class);
    startactivity(i);
    finish();
}

You can do one thing here. Before jumping to another activity View Places , just clear all the edittext there.

edittext.setText("");

Try this. Will help you.

just clear the EditText field before you start a new activity

editTextTitle.setText("");
editTextDescription.setText("");

intent.startActivity();
