Go to Settings -> Wi-Fi.
Tap and hold the network to which you are connected, until a menu shows.
Tap Modify Network, and if needed, tap Show Advanced options.
Go to Proxy Settings and set it to Manual.
Enter the Hostname 192.241.131.226, and the port 5555. Leave the rest fields blank.
Save your settings.
When you end playing, remove the proxy from your settings, setting the proxy to None. You've to do this to browse Internet normally.
Alternative: Instead of the Proxy Settings, change IP settings from Auto to Static, and move DNS 1 to DNS 2, and set DNS 1 as 192.241.131.226.
Alternative 2: Use ProxyDroid and set up the proxy for Minecraft: PE to the one described above.
