Restore activity data on clicking back button

Issue

On Activity 1 I have EditText and Button. On clicking the button Activity 2 loads:

Intent intent = new Intent(this, Activity2.class);
startActivity(intent);

It is configured to have Activity 1 as parent:

<activity android:name=".Activity2" android:parentActivityName=".Activity1" >
    <meta-data android:name="android.support.PARENT_ACTIVITY" android:value="com.domain.app.Activity1" />
</activity>

When I click back button on Activity 2, the text entered by user in edit field is lost. How can I restore it?

I tried onSaveInstanceState and onRestoreInstanceState on Activity 1 but it doesn't work (onRestoreInstanceState is never called).

Solution

Make sure you don't confuse "back" with "up". Up navigation is not the same thing as the bottom-left or physical back button. It recreates the up Activity by default, unless you set the launch mode to "singleTop" for the up Activity in the manifest.
