edit:
when use android.test.purchased sku works fine , change sku product_id giving me error authentication required. need sign google account.
please make sure product id on playstore in app purchase "test_product" should use same sku in code. , if change sku application, possible sku names must exists on playstore in-app products. once run problem , reason sku item not exists on google playstore in-app products add on playstore , resolved.
