java.lang.VerifyError: Rejecting class, failed compile-time verification on calling class

Question

I need to call class data in my selectuser class I am using it when user selects any item from spinner

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    int icon = imgid1[userspinner.getSelectedItemPosition()];
    prefs.edit().putInt("userposition", icon).commit();
    data d = new data();
    data d1 = d.Accept(userspinner.getSelectedItemPosition());
    current.setText(d1.getWeapon_pack());
}

It shows error on

data d = new data();

Here is Stacktrace

I'm not sure if this will help you, but I was getting the same error message on starting a new activity. Disabling "Instant Run" in Android Studio preferences makes this error go away.
