    int density = (int) getResources().getDisplayMetrics().density;

    adWhirlLayout.setAdWhirlInterface(this);

    adWhirlLayout.setMaxWidth((int) (diWidth * density));

    adWhirlLayout.setMaxHeight((int) (diHeight * density));

    layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);

    textView.setText("Below AdWhirlLayout");

    LinearLayout layout = (LinearLayout) findViewById(R.id.layout_main);

    layout.setGravity(Gravity.CENTER_HORIZONTAL);

    layout.addView(adWhirlLayout, layoutParams);

    layout.addView(textView, layoutParams);

    layout.invalidate();

Updated logcat :

Answer 1

Try deleting ur bin directory of the project and then clean the project build it and run. I think ur class file is not present in the .dex extension it sometimes happens when the files dont get properly compiled. Also check if there is no error of build path.

Answer 2

i think everything is allright just replace imported package replace this

 import android.widget.RelativeLayout.LayoutParams;

by

 import android.view.ViewGroup.LayoutParams;
