I am trying to add a jar to a project on Android. I did a test with the maps.jar library. Which has a class named com.google.android.maps.MapView when i do the import of that class. I get the error package com.google.android.maps does not exist
import com.google.android.maps.MapView;

I try to include this jar file in several ways into my gradle.build:

```
dependencies {
 runtime files('/Users/user/Documents/workspace/MyAndroidApp/libs/maps.jar')  
 //runtime fileTree(dir: '/Users/user/Documents/workspace/MyAndroidApp/libs', include: '*.jar')
 //classpath fileTree(dir: '/Users/user/Documents/workspace/MyAndroidApp/libs', include: 'maps.jar')        
}

```

Not luck so far.

Any idea?
Thanks!
