Unable to resolve the error - java.lang.NoClassDefFoundError: com.google.android.gms.R$string

Question

I have seen this question already in StackOverflow but the solutions there just mentioned to import the google-play-services. I did that but still this error is not going and my app is crashing on start. I want to use the google maps and have obtained the API key and put it in the app. Also as I said , I already imported the google-play-services but things are not working and the app is crashing on running it on my mobile. My stacktrace is-:

You need to add dependency in build.gradle in Android studio.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:8.1.0'
 }
