-

i following tutorial code in-app billing items , manage make good, when want know if user purchased item o not, false, when test others devices have beta tester account.

this use item purchased:

mhelper = new iabhelper(mainactivity.this, base64encodedpublickey);      mhelper.startsetup(new iabhelper.oniabsetupfinishedlistener() {        public void oniabsetupfinished(iabresult result) {            iabhelper.queryinventoryfinishedlistener mgotinventorylistener                    = new iabhelper.queryinventoryfinishedlistener() {                public void onqueryinventoryfinished(iabresult result,                                                     inventory inventory) {                     if (result.isfailure()) {                        // handle error here                    }                    else {                        // user have premium upgrade?                        boolean mispremium = inventory.haspurchase(item_sku);                        // update ui accordingly                        toast.maketext(getapplicationcontext(), "" + mispremium, toast.length_long).show();                        if(mispremium){                            buy.setvisibility(view.invisible);                        }                    }                }            };            mhelper.queryinventoryasync(mgotinventorylistener);        }     });

and code purchase item:

buy.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             mhelper.launchpurchaseflow(mainactivity.this, item_sku, 10001,                     new iabhelper.oniabpurchasefinishedlistener() {                         public void oniabpurchasefinished(iabresult result, purchase purchase) {                             if (result.isfailure()) {                                 return;                             } else if (purchase.getsku().equals(item_sku)) {                                 mhelper.queryinventoryasync(new iabhelper.queryinventoryfinishedlistener() {                                     public void onqueryinventoryfinished(iabresult result, inventory inventory) {                                         if (result.isfailure()) {                                         } else {                                             mhelper.consumeasync(inventory.getpurchase(item_sku),                                                     new iabhelper.onconsumefinishedlistener() {                                                         public void onconsumefinished(purchase purchase, iabresult result) {                                                             if (result.issuccess()) {                                                                 buy.setvisibility(view.gone);                                                             } else {                                                             }                                                         }                                                     });                                         }                                     }                                 });                             }                         }                     }, "mypurchasetoken");         }     });

when test app in real device account on beta testers, code works fine when buy item, when close app , open again, first code sais account didnt buy item.

you're consuming product after purchase returns.

see here consumable / non-consumable products: https://developer.android.com/google/play/billing/api.html#consumetypes
