android - What type of operation I'm missing..? -


i read android studio documentation: https://developer.android.com/guide/practices/screens_support.html#declaringtabletlayouts

well documentation pretty obvious, support different screens. use match_parent, wrap_content, create layout-sw folders.. hmm, eazy task.. yep, made 5 layout-sw300dp-700dp folders, every layout owns match-parent , wrap content characteristic.. somehow image isn't getting scaled , want scale image in 1 of linearlayouts..

i know theres lot of answer out there on forum, can see not confusing me, i'm sure i'm missing important end screen support..

should create different size images , place them in drawable folder?

because whenever i'm reviewing layout file example sw600dp image isnt scaled there.. layouts aren't getting scaled..

should configure every layout-sw folders? mean place bigger image, resize layouts.

i need fill linearlayout image. there's white spaces on left , right side of linearlayout

the code belongs relativelayout, has match-parents aswell.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
