I want to use some android apps that gives you bitcoin for small jobs or any thing like that , can you suggest an app for me my friends ?
just search on google play,and you will found some good bitcoin applications bitcoin aliens and some other bitcoin faucet,so far we just found bitcoin faucet for earn bitcoin from android applications,and almost all popuular bitcoin applcations just bitcoin wallet like blockchain or caoinbase.
From my experience and after hearing and reading stories of people who tested some of 'bitcoin apps' it is not worth the risk, some of them are camouflaged malware, wallet stealers and keyloggers.
If you are seeking wallet go to bitcoin.org and pick some tested wallet from their list. And having faucet running on your mobile is just waste of internet bandwidth imo.
