java - Amazon S3 - List ALL objects without hierarchy summaries -


for it's worth, amazon s3 library being used perform operations on hcp. perhaps limits version of amazon s3 can use or changes interpretation of folder. understanding is, both amazon s3 , hcp can acknowledge full paths objects , ignore folders, i'm having difficulty getting requests that.

say have:

  • something/over/here/object1
  • something/over/there/object2
  • somewhere/far/object3

and want every object under something/. here request attempt:

listobjectsrequest listsomeobjects= new listobjectsrequest() .withbucketname("bucket") .withdelimiter("/") .withprefix("something/") .withmaxkeys("100") // maybe not necessary since stops @ 1000 .withmarker(null); // used after first request, imagine objectlisting objectsreturned = this.hs3client.listobjects(listsomeobjects);

objectsreturned gives me few options:

  • getcommonprefixes() - if include delimiter, returns something/over. otherwise, appears empty.
  • getobjectsummaries() - delimiter, returns objects under something/ , itself. in case, has itself. without delimiter, returns list of object summaries something/, something/over/, something/over/here, something/over/there/, something/over/here/object1, something/over/there/object2.
  • getbucketname(), getmarker(), getmaxkeys(), getdelimiter(), getnextmarker(), getprefix() - these don't appear need

i need list of full object names: something/over/here/object1, something/over/there/object2

looping through of getobjectsummaries() filter results last resort. using incredible amount of small requests account subfolders may not viable our use case. there way list of full object names common prefix without going through keys in getobjectsummaries()?

which amazon library version using?

i can tell i've been using 

amazons3.listobjects(string bucketname, string prefix)

and received list of existing matching keys. actual objects, not "virtual folder" subpaths (using getobjectsummaries method do)

as far know equivalent code without delimiter (keeping aside maxkeys).

i used version 1.10.52 in case matters (would surprised).

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
