Hi everybody, I was wondering on how to implement drawing polylines on google maps v2 by the user. After doing alot of googling I found this stackoverflow.com/questions/20901141/how-to-draw-free-hand-polygon-in-google-map-v2-in-android tutorial that claimed that I could achieve it by following the guidelines. But When I tried it implementing it, I got a blank google map fragment. Guys do think something is missing in this tutorial or I am the one not getting it right?

Could you paste your code using pastebin.com or similar? Do you get any message at the spot where the map fragment should be?
here is the link to the code pastebin.com/1xgKiBdi
What you try to accomplice could be done in much less code than you have now buddy. I will take a huge part of your code and remove the unnecessary. But first I will compile your code to see if you're missing any libraries or if you re using any outdated libraries. I will reply again with the outcome of this post within an hour. Im currently not at work yet.

Okay so I compiled your code and indeed it gave me a white map without the possibility to scroll. I remembered having a similar problem some weeks ago and found out that you didn't add a valid api key to your manifest. You require to add a valid api key in your androidmanifest.xml in order to let it work.
Example of an api key in the Google Developer Console: http://prntscr.com/57wbng

This is how your app should look like after adding the API key. As you can see in my first screenshot above, I added a new allowed application to the list:
