java.lang.ClassNotFoundException: Didn't find class "com.google.android.maps.MapView"

Question

I am trying to add Map functionality to my app. My IDE is AndroidStudio. I've gone to the SDK Manager and installed both Google Play services and Google repository.

Then, in my gradle file, I've added google play services:

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.android.support:support-v4:19.1.+'
    compile 'com.google.android.gms:play-services:4.3.23'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

After this, I've synced the project with the gradle files.

In my fragment, I've added MapView (and my API key). No error during compile, however, I get this during runtime:

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.maps.MapView" on path: DexPathList[[zip file "/data/app/com.app.app-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.blueforcemedia.blueforcetracker-1, /vendor/lib, /system/lib]]
            at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)
    }

What am I doing wrong?

Build Path=>Configure Build Path, then add the external jar. Also check the permissions..https://developers.google.com/maps/documentation/android/v1/hello-mapview — ajitksharma, May 27 '14 at 07:12
right click on project, then select build path and them configure build path — ajitksharma, May 27 '14 at 07:21
@ajitksharma When I right click on project, there's no option 'build path' — 0xSina, May 27 '14 at 07:28

The library was provided during the compile, but it's not present at runtime. Your application is trying to invoke a method from library which is not present.

How can I make sure it's there on runtime? – 0xSina May 27 '14 at 07:29

Once i have got this exception for not adding the launcher icon in the manifest.xml(tag) and also for not setting up the target project properties correctly.
