android - ACTION_CANCEL when touch size becomes too large? -

i researching "in-pocket" smartphone interaction. using android implementation , have run next problem:

whenever press fingers firmly against screen (which happens lot in utilize case), android issues action_cancel current motionevent , app (and in fact every app tried) stops receiving touch events until fingers lifted off screen. utilize lg g2 , samsung galaxy alpha testing. on g2, problem seems occur when getpressure() first exceeds 1.0 1 pointer. galaxy alpha, however, returns 1.0 getpressure(), behaves g2. other parameters vary seem cluster around values when action_cancel occurs.

i have found few similar cases (e.g. motionevent.action_cancel blocking subsequent action_up on button) , no solution. tried requestdisallowintercepttouchevent() no avail. can tell logs, getevent , show pointer location developer options scheme (viewrootimpl, exact) keeps reporting events after problem occurs, not dispatched app anymore due action_cancel.

does know whether behavior intended , whether there way around this? suppose seek reading events straight /dev/input/event<x>, wondering if there simpler solution.

sorry long-winded post! love hear suggestions.

android touch multi-touch motionevent

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
