For Android Studio:
Short Version:
- Add the following line to your `build.gradle` file: `implementation 'com.android.support:support-v4:YOUR_TARGET_VERSION'`
Long Version:
Go to File -> Project Structure
Go to "Dependencies" Tab -> Click on the Plus sign -> Go to "Library dependency"
Select the support library "support-v4 (com.android.support:support-v4:YOUR_TARGET_VERSION)"

Rebuild your project and now everything should work.

Problem
I am trying to run the code provided HERE I downloaded the code from their Github and imported into Android SDK, but it shows error at the lines ``` import android.support.v4.app.FragmentActivity; import android.support.v4.app.NavUtils; ``` in multiple files. However if I check the Android SDK Manager, the `Android Support Library` as well as the `Android Support Repository` in the Extras folder are both installed. I can also see the support folder and it's contents in the `SDK_INSTALL\sdk\extras\android\support` directory. It also has the v4 folder which also contains the `android-support-v4.jar` and the `src` folder. THen why is it still showing the error, how do I resolve it and how do I get that sample code running? THe sample code is for an RSS reader app, if that's relevant.
