java - Cannot Resolve ContextCompat in Android

Question

I have an AlertDialogue object called dialog. I am attempting to add an icon to it. I see that this syntax is now deprecated:

dialog.setIcon(getResources().getDrawable(R.drawable.myImage);

I'm reading everywhere that this should work:

dialog.setIcon(ContextCompat.getDrawable(context, R.drawable.myImage));

However, the ContextCompat syntax is not being recognized by Android Studio. Is there something that I should be importing? Thank you.

***Update: Thank's to @Sharj for the correct answer below. I made a quick video too if you guys need a visual: https://www.youtube.com/watch?v=eFiaO0srQro&feature=youtu.be

Answer 1

ContextCompat is part of support library v4. Have you added support library 4 to your project?

android.support.v4.content.ContextCompat

You can include support library to your build.gradle file under app folder if you haven't already

dependencies {
// other stuff here
    compile 'com.android.support:support-v4:23.0.0'
// update the 23.0.0 to latest version available

}
