java - How to parse this nested JSON array and JSON object View_ID in android -


how "view_id":"v1" , view array.
what create not generating proper response. thing doing wrong?

here response get:

{"success":true,"total":2,"view_id":"v1","view":[{"id":"1","button_id":"acc123_b1","publish_topic":"\/ziniks\/acc123\/sw1","subscribe_topic":"\/ziniks\/acc123\/sw1_status"},{"id":"2","button_id":"acc123_b2","publish_topic":"\/ziniks\/acc123\/sw2","subscribe_topic":"\/ziniks\/acc123\/sw2_status"}]}

what created response:

jsonobject mainobj = new jsonobject(response); if(mainobj != null){     jsonarray list = mainobj.getjsonarray("view");     if(list != null){         for(int j = 0; j < list.length();j++){             jsonobject innerelem = list.getjsonobject(j);             if(innerelem != null){                 string button_id = innerelem.getstring("button_id");                 toast.maketext(qrcode.this, button_id, toast.length_short).show();             }         }     } } 

    try bellow.   jsonobject mainobj = new jsonobject(response); if(mainobj != null){     string viewid = mainobj.getstring("view_id");  // here view_id.      jsonarray list = mainobj.getjsonarray("view");  // here view array.      if(list != null){ for(int j = 0; j < list.length();j++){ jsonobject innerelem = list.getjsonobject(j); if(innerelem != null){ string button_id = innerelem.getstring("button_id"); toast.maketext(qrcode.this, button_id, toast.length_short).show(); } } } }

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...

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() .
