You can either show a map inside your own activity as written in the previous answer's link or you can fire an intent to open the Google Maps application in your device. You can find the relevant intent here: http://developer.android.com/guide/appendix/g-app-intents.html
To start with showing Map in your Activity begin with http://developer.android.com/guide/tutorials/views/hello-mapview.html
And to show your location in attractive manner use https://github.com/jgilfelt/android-mapviewballoons
