I need to type in Bangla. I want to make a custom bangla layout. I'm looking for something like Windows Keyboard Layout Creator.

You can create custom layouts for any variants excepts latin input (this requires root-access, so you can't).

At first, try to update Blackberry Keyboard from Google Play and check settings of this app. If you don't satisfied, you need to decompile BB Keyboard and create your own layout by editing XML files. As for me, I made it for Russian layout, all works fine. Then, you need to change package name, enable new input method and use it. It's hard way - you may meet some bugs, and you need to know many technical issues.

Can you please guide me the whole process? Or atleast give me the references so that I can work own my own?

+1 to that. I decompiled keyboard APK but there's a lot of XML files so I got lost a bit.
If anybody can point me got right XML that'll be highly appreciated.
