android - Only one row can be inserted into SQLite database -


i tried extract data json , put database.

this inserted:

 (int = 0; < listarray.length(); i++) {              //extraction "time" , "weather_description"             //............              //insertion:              contentvalues values = new contentvalues();              //values.put(weatherentry._id,i);             values.put(weatherentry.date_column, time);             values.put(weatherentry.description_column, weather_description);              getcontentresolver().insert(weatherentry.content_uri, values); }

sqliteopenhelper:

public class weatherdb extends sqliteopenhelper {    private static final int database_version = 1;   static final string database_name = "weather.db";    public weatherdb(context context) {       super(context,database_name,null,database_version);   }    @override   public void oncreate(sqlitedatabase sqlitedatabase) {       string weather_query = "create table "+ weatherentry.weather_table_name+" ("+               weatherentry._id+" integer primary key autoincrement, "+               weatherentry.date_column+" text, "+               weatherentry.description_column+" text );";        sqlitedatabase.execsql(weather_query);   }    @override   public void onupgrade(sqlitedatabase sqlitedatabase, int i, int i1) {    } }

only first row (with _id=0) able go database.

i got error message: android.database.sqlite.sqliteconstraintexception: unique constraint failed: weather._id (code 1555)

try add autoincrement instead on inserting i : 

weatherentry._id+" integer primary key autoincrement"

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() .
