The import android.support.v7.app cannot be resolved

You need to add the appropriate dependency to your module gradle.build file as follows:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.2'
}

Make sure to synchronize your build.gradle file (Right click on file --> Synchronize 'build.gradle') and Clean your project (Build --> Clean Project) after the change.

The import android.support.v7.app cannot be resolved

After you add appcompat_v7 to your dependencies, be sure that the libs folder from your project are empty. By default, an android-support-v4.jar is created when you define your project, so this will cause conflict when you declare appcompat_v7 library as your dependency.

So, the first thing you need to do is check the folder .../My_Project/libs and fearlessly delete the file android-support-v4.jar.

Then, add the appcompat_v7 library as a dependency of your project:
To do this, if you are using Eclipse:

1. Right click in your project folder, located in the Navigator.
2. Click in properties, in the final of the list.
3. In the Properties window, select the Android option (left menu).
4. In the box Library, add your new reference.

If you are using Android Studio, you can follow the steps mentioned in the @Joey Garcia's comment.
