How do I use Roboto in my android app

Question

I have been researching how I might user Roboto in my android app. I stumbled on a seemingly promising git project dedicated specifically to what I needed. But when I download the project, it refuses to work. Some of the things I try as troubleshooting

• properties > android > Android 4.4.2
• change from minSdkVersion 3 to 11: android:minSdkVersion="11"

I am still getting

error: No resource identifier found for attribute 'typeface' in package 
 'com.devspark.robototextview.sample'

in the single layout file: activity_main.xml

The project is at https://github.com/johnkil/Android-RobotoTextView

Does anyone know how I might get it to work or have some advise at using Roboto with such equivalent simplicity?

Update

I am using eclipse on mac osx mavericks. I just checked and see that the src folder is empty and that the MainActivity.java file is literally under the path of folders consisting: java>com>devspark>robototextview>sample. So my first guess is that eclipse does not know how to import the project. Does anyone know how I might fix that, if indeed it's the problem. By the way, all my projects are on git and I have been using samples and libraries from git for a while now. So the problem is likely this particular project.

Sample Layout :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent">

    <TextView
            android:id="@+id/custom_font"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="This is the roboto font."/>

</LinearLayout>

Place the font file in assets/fonts (Create the fonts inside the assets folder)

Inside the activity :

TextView txt = (TextView) findViewById(R.id.custom_font);
Typeface font = Typeface.createFromAsset(getAssets(), "fonts/roboto.ttf");
txt.setTypeface(font);
