Urgent Android Developer to Fix Critical Bug Now

We need an Android developer to work now and fix an urgent bug within 2~3 hours. We have a WebView loading web page with file upload fields, it works on all versions of Android with the overrides we have implemented. However, file upload fields do not work in 4.4 because it is a known bug (See: [login to view URL]) Therefore we need someone to implement the solution here: [login to view URL] Note. We already have existing Javascript Bridge in our app, so the implementation should be fast. We need you to start now and finish in a few hours. Our backend developer will be with you to let you know the backend API to POST the files etc.
