google datastore gql query with limit and offset cursors? -


i'm trying use cursors large result sets. documentation indicates can use cursors gql query using php can't seem work.

has got working? if doesn't work gql query, show me example of how implement this?

    $query = $datastore->gqlquery('select * h_stats field1 = @parm1 , date >= @startdate , date < @enddate limit @limitby offset @cursor', [                                   'bindings' => [                                     'parm1' => '5700305828184064',                                     'startdate' => '1501545600',                                     'enddate' => '1501632000',                                     'limitby' => 10,                                     'cursor' => 'cursor_string_here'                                   ]     ]);

i figured out. couldn't find possible gql query. it's possible normal query.

hope helps out google docs bad examples.

$datastore = new google\cloud\datastore\datastoreclient([     'projectid' => $projectid, ]);        function cursor_paging($datastore, $querykind, $pagesize, $parm1, $startdate, $enddate, $pagecursor = '')     {          $query = $datastore->query()             ->kind($querykind)             ->filter('field1', '=', $parm1)             ->filter('date', '>=', $startdate)             ->filter('date', '<', $enddate)             ->limit($pagesize)             ->start($pagecursor);                 $result = $datastore->runquery($query);         $nextpagecursor = '';         $entities = [];          foreach ($result $entity) {             $nextpagecursor = $entity->cursor();             $entities[] = $entity;         }         return array(             'nextpagecursor' => $nextpagecursor,             'entities' => $entities         );      }

this how used function provided in google cloud datastore php docs.

    $pagesize = 500;     $querykind = "your_kind";     $result = cursor_paging($datastore, $querykind, $pagesize, $currentthermostat, $startdate, $enddate);      $countrows = 0;      ($x=0; $x < $pagesize; $x++) {          $counter = 0;          foreach ($result['entities'] $item) {             print($countrows . " " . $item['data']);             $countrows++;             $counter++;         }          $result = cursor_paging($datastore, $querykind, $pagesize, $currentthermostat, $startdate, $enddate, $result['nextpagecursor']);          if ($counter > 0) {             $x = 0;         } else {             $x = $pagesize;  //exit loop when no more results         }     }

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
