Delete App (.apk) in emulator? -

-

i know of 2 ways of deleting app under development emulator:

  1. using emulator gui: settings > applications > manage applications > uninstall
  2. using adb: adb uninstall

i may have discovered third way, using 'adb shell':

rm /data/app/<package>.apk

it seems, however, isn't way delete apps because there may additional information associated (registration?).

what information , can found?

it's interesting mention this. ran quick home made test shed light onto question.

generally, when install .apk file, android creates internal storage area located @ /data/data/< package name of launching activity>. used internal caching area cant accessed other apps or phone user. can read in little bit more detail in internal storage chapter of androids data storage section. area exclusively used app , can write private data there.

once uninstall app theoretically, internal storage area deleted. first 2 ways outlined indeed that: .apk file in /data/app/ deleted aswell internal storage area in /data/data/.

however if used adb shell , run rm command, removed .apk file in /data/app/. internal storage area in in /data/data/ not deleted. in essence correct additional information app not deleted. on flip side, if reinstall app after running command, existing internal storage area gets overwritten fresh copy of being installed.

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.
