add support v7 android studio ya - BONGDATV

The import android.support.v7.app.ActionBarActivity statement imports the ActionBarActivity class from the android.support.v7.app package. This class is a subclass of the Activity class and provides a number of features that are specific to Android 5.0 (Lollipop) and later.

How you setup the Android Support Libraries in your development project depends on what features you want to use and what range of Android platform versions you want to support with your application. This document guides you through downloading the Support Library package and adding libraries to your development environment.

Possible solutions: Check your .gradle file to make sure you're not referencing an outdated version. Resync your project (File >Sync project with Gradle files) Rebuild your project (Build >rebuild) Clean your project (Build >clean project) Close and restart Android Studio. Update Android Studio.

Using Android Studio you have to add the dependency of the support library that was not indicated in the tutorial. dependencies { implementation 'com.android.support:appcompat-v7:22..0' }
