I am facing issue with google play service ads. I am using rev 17 version of play service in my app and using android 4.4.2 with installed play service version 4.8.20.
But getting a warning as below Google Play services out of date. Requires 4452000 but found 4325034. And ads are not displayed .
But works fine on Gingerbread device 2.3.x .
Earlier I was getting below error on kitkat and app was crashing.
java.lang.SecurityException: attempting to read gservices without permission: Neither user 10096 nor current process has com.google.android.providers.gsf.permission.READ_GSERVICES.
Than I added READ_GSERVICES permission, its not crashing but ads are not displayed because of above out of date issue.
Please suggest a solution.
