Finally, I have to setup zawgyi font and keyboard in android phone myself. In my earlier time, my friends’d done that for me. Thanks to them. 😀
Well, the following is the useful link that you can install zawgyi font and keyboard. I’d successfully done in my Samsung Ace 2. I hope it will be ok for you too. Try that.
Zawgyi One TTF v2.0
Use Zawgyi-One Flipfont if you using galaxy devices. It has 8 font pack Zawgyi-One
It means you can choose font that you want. I like “Myanmar + Iphone” font from this.
Installation instruction — Setting > Display > Font Style > Zawgyi One TTF
