Develop an app that has: - Ability to read USB OTG data and parse / decode data - Create a graphical GUI that would display some of this data in realtime - Log all data from USB OTG - Email capable - Colour selections for interface, etc - Write to USB OTG (maybe, not sure of this) I am a SW engineer by trade so I will provide a detailed description, graphics, etc. before we start. This will provide a very easy requirement base to work from. Additionally I will need some "proof of concept code" as we go along to ensure that proper progress is being made and that we are in sync for the cost to deliverable schedule. A non-disclosure agreement needs to be signed. I will need to have more details about ownership, how to sell my app, etc.

Hi, I am new freelancer here, but I worked in android for 5 years. This app need following key tech: 1) USB device detection: Register filter by android.hardware.usb.action.USB_DEVICE_ATTACHED to launch app when an USB device is attached. Of course, we can use vid/pid to filter USB devices who is desire to communicate with. Then can use UsbManager/UsbDevice get the device instance to communicate. In one words, this app only can work in android device which support USB OTG. Am I right? I suppose this app work on a USB OTG android device as a host. 2) data transfer: Use UsbDeviceConnection to read/write data. Also, this part need you to provide a detail spec to define the data format. 3) graphical GUI to display in realtime: need custom a view to draw the graphical GUI in realtime. Maybe need to extend from View depending on what effect you want. 4) Log all data: Write raw data to storage or store data in SQLite database depending on the data format. 5) Email capable: Suppose to send Email by using some stock email client. And it's easy. if need to build-in a SMTP in our app also is fine. But this need user to register an email account in our app. This project is my first project, and I want to gain confidence here. Hope to work for you. I can provide a demo in two days if you required.
