android - Can Honeycomb Loaders solve problems with AsyncTask + UI update? -

-

doing in background , updating ui hard implement correctly in android. it's badly designed. typical example asynctask fetches web , displays result. there 2 problems this:

  1. the asynctask has reference activity (because needs update ui). after screen orientation change, activity restarted. asynctask still references old destroyed activity therefore can't update ui of new activity.

  2. this can lead outofmemoryexception. imagine have activity lots of bitmaps , start asynctask. press (activity finished) asynctask still running , because references activity, activity bitmaps still in memory. repeat (start activity , back) , have force close sooner or later.

this can solved, way complicated. in 1 activity have 3 different asynctasks, each of them can running in several instances simultaneously. implementing correctly frustrating. code becomes hard understand , debug.

can honeycomb loaders somehow solve this? , there way use them in pre-honeycomb android versions?

yes, experience loader seem solve common problems people have asynctasks , configuration changes.

i think google said fragments static library include loaders yes, should work backwards when library released.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
