you need maintain persistent storage (e.g. sqlite database) store pending operations takes longer time , depends upon many circumstances (e.g. network availability, whether activity killed etc). can maintain flag there upload status is, example, set "pending" when user clicked photo , changed "done" on upload success (or can erased) in onsuccesslistener.

using dedicated service whole process reliable.
