Cannot register activity to open email attachments on Android -

-

i've been working on update shopping assistant, shopping list management application , trying create functionality email shopping lists nothing json encoded text files contain shopping list created application different user has application installed. when email received, , 1 tries preview/open attachment, shopping assistant app should presented option open attachment. however, no matter intent filers have tried, doesn't work. can't app called when attachment previewed. true created custom mime type called application/sal (sal extension give file attachment) , added intent filter manifest file looks this:

       <intent-filter>             <action android:name="android.intent.action.action_view" />             <category android:name="android.intent.category.default" />             <data android:mimetype="application/sal" />         </intent-filter>

but no success. i've tried use text/xml mime type in email , in filter (file content remaining same), , got dialog choosing between file viewer , app, still shopping assistant didn't show in list.

i've been reading examples , questions on subject stackoverflow , other forums, , none of examples helped, suggestions particular conundrum highly appreciated.

thanks, mihai

it true created custom mime type called application/sal

no email client knows this, , hence not used sender. means not received on device.

<action android:name="android.intent.action.action_view" />

remove action_ value.

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.
