Andriod app to read USB OTG in realtime, parse data, display some, log all.

Hi, I am developing a data collection system on Android. Including connecting to USB. My last development of multichannel seismic data acquisition system. External device is connected to USB OTG, data is displayed in the form of graphs.

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.
