Block This is a DNS/VPN based ad blocking & privacy app for Android, that blocks malicious or unwanted internet content by filtering DNS requests and redirecting them to 127.0.0.1 (localhost). It uses a dummy VPN client in order to go around the restrictions in Android and change the DNS settings without having root access. The backend behind the app is a DNS based on PowerDNS - an open source DNS management software working with MySQL as a datasource.

To get the latest release of Block This, go to:
The main logic that blocks the host names is contained within your own DNS server. You can setup one using PDNS (https://www.powerdns.com/). Once this is done, add the following in your app/src/main/assets/config.properties file. For testing the app you can use any valid DNS address (e.g. 8.8.8.8, 8.8.4.4) but ofcourse using a public DNS will not block any ads.
dns1=YOUR_DNS1_IP_ADDRESS
dns2=YOUR_DNS2_IP_ADDRESS
If you wish to run it locally and want to use fabric (https://fabric.io/) for issue tracking you will have to create your own app/fabric.properties file containing the following (optional):
apiSecret=YOUR_FABRIC_API_SECRET
apiKey=YOUR_FABRIC_API_KEY
In order for "Games" support section from the menu to work you can register with AppNext (https://www.appnext.com) and get an Api Key. Once this is done, add it to your app/src/main/assets/config.properties file (optional):
appNextApiKey=YOUR_APP_NEXT_API_KEY

I created the app for my own convenience as I needed a privacy and ad blocking solution for my Android device, which I did not want to root. The app worked so well for me that I decided to put it on the Play Store. It had a huge success with almost 1 million downloads in just 2 months, but then it was taken down by Google. It is now hosted on my website as an APK. I open source it with the hope to get further developed and supported by the community.
