android - Prevent background service from being killed due to "detect excessive cpu on forked process" -

-

i debugging issue of syncthing android wrapper. android application wraps native binary of syncthing project , provides additional functionality starting/stopping based on connecting wifi, power, etc.

unfortunately, there have been issues service not auto-starting on wifi change anymore, handsets have been upgraded android 6. since personal handset has been upgraded 6.0.1 recently, able debug issue , today noticed following:

07-06 20:52:26.562  1181  1363 activitymanager: [bgdetect]chkexcesscpu dokills: true uptime: 300309 07-06 20:52:26.960  1181  1363 activitymanager: [bgdetect]detect excessive cpu on forked process libsyncthing.so(pid : 2758) plan stop 371060 during 300309 07-06 20:52:26.960  1181  1363 activitymanager: [bgdetect]force stop com.nutomic.syncthingandroid.debug (uid 10132) 07-06 20:52:26.965  1181  1363 activitymanager: force stopping com.nutomic.syncthingandroid.debug appid=10132 user=0: pid 1181 07-06 20:52:26.966  1181  1363 activitymanager: killing 1360:com.nutomic.syncthingandroid.debug/u0a132 (adj 15): stop com.nutomic.syncthingandroid.debug 07-06 20:52:26.968  1181  1363 w activitymanager: scheduling restart of crashed service com.nutomic.syncthingandroid.debug/com.nutomic.syncthingandroid.syncthing.syncthingservice in 1000ms 07-06 20:52:26.968  1181  1354 v activitymanager: killprocessgroupasync took 1 ms pid 1360 on thread 14 07-06 20:52:26.971  1181  6410 libprocessgroup: killing pid 2758 in uid 10132 part of process group 1360 07-06 20:52:26.973  1181  6410 libprocessgroup: killing pid 2758 in uid 10132 part of process group 1360 07-06 20:52:26.974  1181  1363 activitymanager:   force stopping service servicerecord{47304c8 u0 com.nutomic.syncthingandroid.debug/com.nutomic.syncthingandroid.syncthing.syncthingservice}

the syncthing protocol quite heavy on cpu side, regarding encryption, hashing, etc. seems service force-stopped due high cpu demands of forked native binary.

the application marked "no battery optimization", still being killed. there way prevent activitymanager killing application due cpu demands of forked process?

c++ - wxDataViewModel: What is it and how do i use it? -

-
i read documentation http://docs.wxwidgets.org/3.0/classwx_data_view_model.html several times hardly answers questions. maybe i'm confused function of class? so riddle this: is view model know mvvm? how implement derivative? how set data in containing wxdataviewlistctrl? is right/recommended way make table? as name subtly hints, wxdataviewmodel indeed model in usual mvc design (while wxdataviewctrl both view , controller). you can see couple of examples of custom models in dataview sample . notice wxdataviewlistctrl compatibility class made transitioning code using wxlistctrl wxdataviewctrl , defines own trivial list model. don't recommend using unless need.
