android softkeyboard showSoftInput vs toggleSoftInput

It seems that the keyboard is initially displayed but hidden by something else, because the following works (but is actually a dirty work-around):

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
editText.postDelayed(new Runnable()
{
    @Override
    public void run()
    {
        editText.requestFocus();
        imm.showSoftInput(editText, 0);
    }
}, 100);

And when looking at logcat I suspect the cause behind this message hides the keyboard initially shown:

Hide Clipboard dialog at Starting input: finished by someone else… !
