I solve this with next hack:

    //Слушатель: Открыть панель выбора смайлов
    showEmojiBoard.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            main.helpFuncs.fastVibrate(getContext());
            if (main.globals_.emojiPopup.isShowing()){
                //закрыть эмоции
                main.globals_.emojiPopup.dismiss();
            }else{
                //закрыть клавиатуру
                InputMethodManager imm = (InputMethodManager)getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(emojiEditText.getWindowToken(), 0);
                //открыть эмоции
                main.globals_.emojiPopup.toggle();
            }
        }
    });

Have you looked at the sample and does that work?

Yes, not only look. I use example, but example work good only with code in my onClickListener. Without this, example can only show smiles board.

Which device are you using and does it have a custom keyboard?

Sony Ericsson Xperia mini sk17i (android 4.0.4) without custom keyboard and Samsung Galaxy S3 without custom keyboard

I do know that there seems to be something mixed up in some cases and on some devices I just can't never reproduce it hence I don't know what's going on.

Adding that logic may work for that particular device however it can break many more devices.

I'll close this as this should be fixed with 0.4.0-SNAPSHOT. If it isn't please create / reopen the issue. I'll cut a release soon.
