Q:

Android Accessibility Service Focus EditText

I am writing an accessibility service.  I've been trying to focus EditText fields in a way that pops up the software keyboard and I have been unsuccessful.  I am able to get the cursor into the EditText field, but the soft keyboard doesn't pop up.  Given EditTextNode is an AccessibilityNodeInfo that I have gotten from various accessibility events and that said nodeInfo isEditable, isFocusable, isVisibleToUser and isClickable when I attempt all of these actions and they all return true upon completion.
editTextNode.performAction(AccessibilityNodeInfo.ACTION_CLICK);

In my mind the above should simply work, and the fact that it does not is a bug in the Accessibility API, if not for my entire android version, at the very least on my device (Droid Ultra, Android 4.4.4).  I have also tried:
editTextNode.performAction(AccessibilityNodeInfo.ACTION_FOCUS);

Puts focus into the field so I can see the input cursor, but no keyboard.
editTextNode.performAction(AccessibilityNodeInfo.ACTION_ACCESSIBILITY_FOCUS);

Doesn't really do anything unless talkback is enabled.
editTextNode.performAction(AccessibilityNodeInfo.ACTION_SET_SELECTION, someBundle);

Along with appropriate arguments this will work, but only if there is already text in the editText field.  I need to pull the keyboard up on empty text fields as well.  Yes, I tried inputing 0,0 for start and end text selection arguments.  The SET_SELECTION method only works with text in the field! 
This has been frustrating me for a couple days, hopefully you guys can help.  Though I believe I've stumbled onto a bug and am going to have to wait for Android to update.  Because the ACTION_CLICK method should really be all that is needed.  But, I could be missing something silly, Accessibility API Doc is somewhat scant.  Am willing to attempt anything.

To restate @alanv's comment in answer form:
You are correct, it is a bug in accessibility services prior to API 21.
