Utilize both Play Services and AdMob SDK
As MH. pointed out in this question, one no longer needs to include GoogleAdMobAdsSdk-x.x.x.jar in their Android project if they include Google Play Services (see the migration guide). However, I want to, and I'm having trouble.
The problem: the google-play-services_lib project includes a definition for com.google.ads.AdRequest that is deprecated, and has a private constructor. It ends up in the classpath in front of the AdMob jar (within the "Android Private Libraries" entry), so when I try to use it in my code it end up trying to use the deprecated one, resulting in the error: The constructor AdRequest() is not visible. I see no way to re-order the entries inside "Android Private Libraries".
Why do I want to use both, you ask? I have a single library project with many useful classes, including some utility classes for dealing both Play Services and AdMob. Some of my apps that use that library project use the AdMob utility classes, but not Play Services.
Answer
I've been testing this, and some changes are required in order to get this working through Google Play Services.
In first place you should remove all imports referencing to old com.google.ads.* , since they are now located on com.google.android.gms.ads.*.
As you mentioned, some more changes need to be done:
You cannot instantiate an AdRequest the way it used to be done, but using an AdRequest.Builder as follows:
AdRequest adRequest = new AdRequest.Builder().build();
Also, make sure you replace the name of the package on all layouts, so they call <com.google.android.gms.ads.AdView instead of <com.google.ads.AdView.
I think that's all. Good luck!
