// Possible geo uris:
// geo:lat,long
// geo:lat,long?z=zoom
// geo:0,0?q=AddressOrPlace
double latitude = 48.3895;
double longitude = 9.1869;
int zoom = 13;
String uriBegin = "geo:" + latitude + "," + longitude;
String query = latitude + "," + longitude;
String encodedQuery = Uri.encode(query);
String uriString = uriBegin + "?q=" + encodedQuery + "&z=" + zoom;
Uri uri = Uri.parse(uriString);
i = new Intent(android.content.Intent.ACTION_VIEW, uri);
showActivity(i);

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:id="@+id/root"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:orientation="horizontal" >

<fragment android:id="@+id/map"
		  android:layout_width="match_parent"
		  android:layout_height="match_parent"

</FrameLayout>
