So client wants an android app that implements some legacy Epson printer SDK, works on a chinese Windows device with an android Emulator on it, connects to local Webservice that had to be configurated and ran (local Network) , sends and tracks data, if Server down then handle it on the Client and reconnect as soon as Server up, running own TCP Server on Android device that listens for specific http requests, which make the android connect to an Epson printer to start printing. The stuff that is being printed? A png file that has to be converted to a Bitmap, a QR Code that has to be generated by the bugged base64 encrypted stuff coming via http in (webserver-> Android TCP server)
Dont forget the Software Design (MVP), documentation, research etc.. Im about to finish the app , its my 5th day on this Project, the 6th day was planned to be full testing. Client Calls me and ask me how far I am, I reply, he says ok. 30 minutes later he tells me he wont pay me next time that much because this work should take 3 days, or even 2. "A senior Android developer could do this in 2 days"... When i sent him my notices he called me a liar, his webdev has alot of experience and told him it should take 2-3 days...ffs
