1> I have installed the app. Still I do not see Kannada keyboard. Why?
You need to activate the keyboard by selecting settings, language and keyboard and check on Kannada keyboard. When you are typing a message or something, you long click and when you see the menu input methods, tap on that and select kannada keyboard.
You should go to settings in your phone. You should select
Language and Keyboard
TextSettings – Check your keyboard name here. Check Kannada keyboard
Now this keyboard is activated.
When you are typing anything, to use this keyboard, long click on the text box. You get the context menu.
In that select Input method option
Again check kannada keyboard
Now you touch on the text box, the kannada/hindi keyboad will appear on your phone.
2> I have installed the app and activated the keyboard. But when I type, I see square boxes instead of kannada/Hindi letters. Why?
It seems you do not have the kannada/hindi font in your mobile. You should install the font. Download the kannada font/Hindi font, root your phone and then install the font. The steps are explained in this blog.
You can download Kannada fonts from http://www.wazu.jp/gallery/Fonts_Kannada.html. Many fonts are given. At least one of them will work :). Then you should install SuperOneClick program to root your android phone. Once rooted you should overwrite /system/fonts/DroidSansFallback.ttf with your downloaded kannada ttf file.
For more detailed instructions you can refer to this page.
