Hello everyone, I am trying to implement Unity Ads to my project. When i tried to compile to .apk, it gives this error. I couldn't find any solution. I don't have a androidmanifest and i don't know how to write one, if i have to. My Unity version : 5.4

 FileNotFoundException: Could not find file "C:\Users\Burak Alp\Documents\Complete C#\Temp\StagingArea\AndroidManifest.xml".
