with interstitial when showing. Here is log:

I have attached SizableStateManger class

UPDATE: Found a solution. There must be additional resource dimens.xml with the following text:

<resources>
    <dimen name="mmadsdk_mraid_resize_close_area_size">50dp</dimen>
</resources>

in res\values folder for package com.millennialmedia.

#AdditionalRes: C:\AdsTest\MopubLib\B4A TEST\res, com.millennialmedia

Thanks
