Did you import it in your class? import com.android.volley.toolbox.JsonObjectRequest;
The easier way is to use the menu option "Code/Optimize Imports" or the shorcut available on your operative system. You will also need to add the dependency to your build.gradle file: compile 'com.android.volley:volley:1.0.0' Or whatever is the newest version number.
