Android testfairy java.lang.VerifyError吗？

Question

After I upload my apk to testfairy and install it I get a java.lang.VerifyError crash

The class extends android.support.v4.app.Fragment

This is the function that is crashing. It crashes on the function execution, not the click but when I remove the onClick . Inner stuff all works.

fitroom_lly is LinearLayout

mixpanel defined :

MixpanelAPI mixpanel = MixpanelAPI.getInstance(getActivity(), getResources().getString(R.string.Mix_Panel_Token));

Function:

private void AddOnFittingRoomClickListener() {
    fitroom_lly.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mixpanel.track("Fitting room");
        }
    });
}

Error:

I work for TestFairy. I need a bit information, is your app multidex'd or a single dex? That's the only VerifyError we ever encountered, and we have an answer for that. Though I would need you to email support at testfairy.com, and one of the technical developer will explain to you the workaround. We're making this solution available to everybody, but in the meanwhile, only support is explaining this.
