EVENT_TYPE_POINTER_DRAGGED spam on Android runtime #1147

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
If you touch and hold your finger on the Touchscreen on Android, 
the event handler gets spammed with EVENT_TYPE_POINTER_DRAGGED events, even 
though the finger is not moved and stays at the same place.
The MoSync emulator behaves normally and doesn't do this, so I guess this 
behaviour is not intended

What is the expected output? What do you see instead?
Expected: I only want to get EVENT_TYPE_POINTER_DRAGGED if the location of the 
pointer changes.
Seen instead:

I'm not sure if this is the problem you refer to but there was a problem in 
Android release runtimes that filled the logs with lots (and I man lots) of 
data which was useful for debug purposes only.  This has been fixed in 2.7 so 
that release runtimes do not send this debug into to the log.  Please advice if 
this is not the problem

As you can see, I'm writing the EVENT_TYPE_POINTER_DRAGGED event to the log 
myself, so this is not the problem you describe.
EVENT_TYPE_POINTER_DRAGGED should only be posted if the pointer location 
changes, but in fact gets constantly posted as long as the stylus is hold down.
To test it, use code from above and look at the log.
Hold down left mouse button in Emulator, move around a bit and then let the 
cursor settle and stay at one point -> No more messages, as there is no change 
of the pointer state.

Do the same thing on Android: Push down with your finger or stylus or whatever 
and hold it down without moving: There are a lot of EVENT_TYPE_POINTER_DRAGGED 
even though the pointer location and button status remains constant.

EVENT_TYPE_POINTER_DRAGGED (234/397/0)
EVENT_TYPE_POINTER_DRAGGED (234/397/0)
EVENT_TYPE_POINTER_DRAGGED (234/397/0)

So the same event gets constantly posted until you release the finger.
