Admob Conflicts with Google Play Services

Unity version : 5.2.1p4 Android SDK platform tools : 23.0.1 Android SDK Build tools: 23.0.2

i followed the instruction for admob on this tutorial https://www.youtube.com/watch?v=q5T98X3EawA and it works fine. admob banner shows properly but as i try to implement google play services for leader boards banner no longer shows and ads no longer requests as the game starts. i knew it dosent request ads because as i use log cat it only shows something like this Pixelkits-Mini:MrtJam3D Pixelkit$ cd /Volumes/Macintosh\ HD/Users/Pixelkit/Desktop/android-sdk-macosx/platform-tools/ Pixelkits-Mini:platform-tools Pixelkit$ ./adb logcat -s Ads --------- beginning of /dev/log/system --------- beginning of /dev/log/main Pixelkits-Mini:platform-tools Pixelkit$ ./adb logcat -s Ads --------- beginning of /dev/log/system --------- beginning of /dev/log/main

tried it many times but ads dont show tried removing google play services and it works fine

uses gps version 0.9.27 (https://github.com/playgameservices/play-games-plugin-for-unity)
