need android developer to fix the source code and get apk from it with required title name, ads, splash screens & functions

there is no additional requirement, everything is already written in the project details i have the source code for android file manager application. and it is attached with this project's details. you have to get me this file manager application which supports android version of atleast 4.1.1. this source code has an issue, that is, this application is creating issue in doing any activity in external sd card (copy/paste/cut/rename/zip/newfolder etc). also this source code is not doing great in moving the data between internal memory of phone and external sd card or USB. there might be some other functions it need to perform, which i may not be able to write right now, so dont bother and feel free to mention. you also have to put banner ads and interstitial ads in it. i will provide the codes. you have to create the activity progress bar because this source code does not have the progress bar while copy/paste/cut/moving/deleting etc data. i will share the sample picture that how this progress bar should be visible to show the acitvity of it. you will have to add the splash screen in it and the icon of this application according to my choice . you will have to add the screen in it with title "My Apps", this screen will only be visible at the end when a user is getting exit from this application. On this page the selected applications or games of play store will be visible on it, if user click on the link of any applicaiton or game, it will route the user to that application's or game's play store link. you will have to provide me the source code from which i can easily get the apk. in the end of this project, when you share the final source code with me; i'll check it via getting the apk from it. once i get the apk from it, you will get your last milestone payment and the project is finished.
