Androidmanifest.xml problem

Hello, after a lot of hours to try to fix it myself and using all answer i found on forums in internet i decide to ask you. Here is my problem : I made a game, using android sdk because this is a game for Android Phones, and before a tryed to instal Google Mobile Ads package all was allright. But since i install this package i can't build anymore, so i did a lot of manipulation to try to fix it but finnaly i lost my first androidmanifest file. So i deleted the Google mobile Ads but i still can't build my project ! So i have two request, first how to get back with a simple classic androidmanifest, and then how to change this file after install Google mobile Ads. Here is my androidmanifest in Asset/Plugins/Android (i deleted all others but everytime i tryed to build new ones are comming in Temp, and this is a basic one i found in my files because i lost my first one): I work with unity 5.3 and in my setting my Minimum API lvl is 15, and i use to put target 23 or 24. Thank you in advance, i hope i give you all you need. I stay close to my computer for quick answer :)
