I read somewhere that all default android applications where opensource.

If this is true, I am trying to find the Google Maps code. Can anyone tell me how I might find it?

Nope

You might want to use Maps API in your application.

Although Android itself is open-source Googles propritary apps are closed source for obvious security and intellectual property reasons.

These proprietary apps include the following:

• Maps
• Navigation
• YouTube
• GMail

If you want to utilize these apps in their provided state you can trigger them using intents.

Each application will require parameters in the intent uri or extra parameters, however examples of these are easy to find.

check in github may be you find a solution there

https://github.com/googlemaps

and you should install these two packages first Google Play Services Google Repository then try to add this fragment in your layout

<fragment
    android:id="@+id/mapView"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

and then you should add this method to initialise the map

private void createMapView(){
    try {
    if(null == googleMap){
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.mapView)).getMap();

        /**
         * If the map is still null after attempted initialisation,
         * show an error to the user
         */
        if(null == googleMap) {
            Toast.makeText(getApplicationContext(),
                    "Error creating map",Toast.LENGTH_SHORT).show();
        }
    }
} catch (NullPointerException exception){
    Log.e("mapApp", exception.toString());
}

}
