使用Google Play服务时Android出现问题

Question

I am using Android Studio 0.8.0 and created a project with Android Wear 4.4. I need to integrate it with Google Play Services. However, I got error as follows:

Caused by: java.lang.IllegalStateException: Unable to find dynamic class com.google.android.gms.maps.internal.CreatorImpl

I already added the play-services-wearable library in my build.gradle file. Also, I added following code in my AndroidManifest.xml file

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

but the error is still.

According to the guide in http://developer.android.com/google/play-services/setup.html , I also added the Proguard Exception in my /proguard-project.txt.

However, it does not work.

Could you give any idea to solve this problem? Thanks!

Be sure to include:

compile 'com.google.android.gms:play-services-wearable:+'

in your dependencies.

So it would be (on the wear project):

dependencies { compile 'com.google.android.gms:play-services-wearable:+' compile 'com.google.android.support:wearable:+' } and in the mobile project:

dependencies { compile 'com.google.android.gms:play-services-wearable:+' wearApp project(':wear') }
