mongodb - Keyword item in monger vector is converted to string -


using monger, writing document contains vector keyword item collection like

(monger.collection/insert-and-return db                                      "test-coll" {:_id 1 :some-vector [:a-keyword]})

which returns expected

{:_id 1, :some-vector [:a-keyword]}

but if fetch particular document like

(monger.collection/find-map-by-id db "test-coll" 1)

the keyword has been changed string

{:_id 1, :some-vector ["a-keyword"]}

is expected behaviour , if why?

this expected behaviour mongo database store doesn't support keywords; json. http://clojuremongodb.info/articles/inserting.html#serialization_of_clojure_data_types_to_dbobject_and_dblist

you have manually convert values keywords using monger.conversion/from-db-object.

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
