I have an Android phone and I cannot find any gambling apps in the Google Play Store. I know it is because of their policies but I am afraid of downloading random APK files from forums. Where do you guys get the official installation files? I do not want to end up with a virus or some fake app that steals my login info.

You are right to be cautious because there are a lot of fake apps out there. You should only ever download the APK directly from the source. Go to http://vavada-india.net/app/ and get the file from there. It is the official page so you know it is clean. The installation takes about a minute, you just have to allow installation from unknown sources in your settings for a moment. It works perfectly on my Samsung.

I did not know I had to change the settings. I will go to the official site you mentioned and grab the file.
