Adding a library Android-studio

Question

I'm having trouble when i add achartengine-1.1.0.jar in my project. When i add

compile file('libs.achartengine-1.1.0.jar') 

in build.gradle, Gradle shows the following message :

Gradle: A problem occurred evaluating project ':NativeCharts'.
Cannot convert the provided notation to an object of type Dependency: /home/***/NativeChartsProject/NativeCharts/libs/achartengine-1.1.0.jar.
  The following types/formats are supported:
    - Instances of Dependency.
    - Strings/CharSequences, e.g. 'org.gradle:gradle-core:1.0'.
    - Maps, e.g. [group: 'org.gradle', name: 'gradle-core', version: '1.0'].
    - FileCollections, e.g. files('some.jar', 'someOther.jar').
    - Projects, e.g. project(':some:project:path').
    - ClassPathNotation, e.g. gradleApi().
  Comprehensive documentation on dependency notations is available in DSL reference for DependencyHandler type.

Thanks in advance. Fab.

The dependency should read compile files(...), not compile file(...). Also in the above you write the path as libs.achartengine-1.1.0.jar, this should be libs/achartengine-1.1.0.jar.
