It’s always convenient to have that little button to “go back” to the previous Activity, and to add it is very simple, just add a directive in your“AndroidManifest.xml“.
<activity
android:name=".BackButtonActivity"
android:parentActivityName=".MainActivity">
<!-- Este meta dado é necessário para versões abaixo da 4.1 -->
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
MainActivity corresponds to the Activity to which the application should return when we click on “return”.
