Access Context context from library

I'm trying to get this api wrapper for android to work.

one of the provided sample methods is:

APIWrapper wrapper = new APIWrapper(context, "YOUR_API_KEY");
Parameters params = new Parameters()
    .addSearch("searchQuery")
    .addFields("*")
    .addOrder("published_at:desc");

wrapper.search(APIWrapper.Endpoint.GAMES, params, new onSuccessCallback(){
    @Override
        public void onSuccess(JSONArray result) {
            // Do something with resulting JSONArray
        }

        @Override
        public void onError(VolleyError error) {
            // Do something on error
        }
});

I imported Context context, but the problem is that "context" seems to be null no matter what.

How do I get Context context to work correctly?

EDIT: Context context=this; worked.

Though when I want to call the same method from another class . Like this:

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        test2 method = new test2();
        method.dostuff4();   // call from other class

Context is null again?

What confused me was the context.

I had to pass it along for it to work. Problem solved

here check this out! its simple injection! but it will do the job for you!

public class MainActivity extends AppCompatActivity{
      private Context context;

   @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    context = this;
    Test2 method = new Test2(context);
    method.dostuff4();   // call from other class

}

// and here should be the structure of the Test2 class

public class Test2 {
 Context context;
 public Test2(Context context){
   this.context = context;
 }

 public void dostuff4(){
 //here now you can use the context in it
 }

}
