Answer: 
In my case Ctrl + Space was overloaded by mac shortcuts. And even in the case, I disabled them, they conflict with Android Studio.

So, I gave them another keys and it solved the problem.

Go to the `System Preferences -> Keyboard -> Shortcuts -> Input Sources` and use new keys for them.

The problem is that Android Studio has different key binding than Eclipse, but you can set the key binding to be the same as in eclipse in android studio settings. Also by default ctrl + space is case sensitive in Android studio, you need to turn that off too.

Move to File -> Settings -> Keymap and change keymaps settings to eclipse so that you can use the short cut keys like in eclipse.

You can set 'Case sensitive completion' to 'None' in IDE Settings > Editor > Code Completion.

That should do it :)
