Hi Everyone, Please read below points before applying for this job. I have clone app of my existing original app, we have changed brand name & republish it on playstore. Below are the issues & modifications i need. 1. The app is making clash when we install the app in device if the original app is already installed in device. It might be due to package name, you need to dig the issue and find out where are places we need to change the package name. There are 3 to 4 places. Our old developer just lost and we are unable to find it out. 2. The app currently support 32-bit, we need migration into 64-bit that it support both without having issue. We have License LIVE TV tab in our app that operated by us, make sure nothing effects it. 3.
