I'd like to pass the host's /dev/urandom device through to a qemu/kvm virtual machine.
Note that /dev/urandom is not seekable, so it's not possible to pass it through as a block device using -hda, -fda, or -sda.
I would expect that I should be able to pass it through as a serial device, but I can't see to get that working.
I have a server that receives a continuous stream of data. As opposed to reading multiple times from a socket, I would like to read the entire data in socket receive buffer with one system call to read().
Of course I can pass a large buffer and read() will try to fill it with all available data.
Can anyone explain what exactly the Android Backup API is used for?
I have read Using the Backup API and Data Backup from the Developer Docs, but it is still unclear to me.
When is data backed up & restored?
Specifically in these situations:
A user installs my app on Device 1, data is backed up, and the user then installs my app on Device 2.
I am working on USB communication between an Android Galaxy S III smartphone and a device which does not conform to Android Open Accessory device definition. I want to transfer asynchronously bulk data from the device to the host. The connection between the host and device works correctly, what has been verified by sending control commands to the device.
I'am trying to implement a program to be installed in two PCs that allow raw packet data transfer using 802.11.
Well, I want to communicate with external device via Wifi interface. The device has a RS232-wlan module. And to command the device from may PC, I have to send commands and messages according to the device communication protocol.
Any ideas to start ?
I am working on a project where we are developing an Android app to read data from an RFID chip through USB. The Android app works fine, reads the RFID data when the USB(with the RFID chip) connected to the Android device. But I want to test the app when the Android device is connected to the PC, and mock the RFID data from the PC. Is it possible? Has anyone tried this?
Thank you
Evening! The device's display broke and I can't connect to the device through wifi. Does anyone have any idea how data rescue could be performed? I don't see a usb port on it either; should there be a dock present together with the device? I haven't it. Any ideas? Any specifics concerning wifi connection that I'm overlooking?
I want to upload a photo from the phone with some data like name and email.
From an Android device I know how to upload a photo and I know how to send data between the phone and the server but how do you do both at the same time?
Should I do them separately?
I am trying to develop an App that can communicate with the Bluetooth device.
As soon as I'm connecting it, its getting disconnected. I don't want it that way. I want disconnection to happen only if the device moves out of range.
I even tried sending data to the device so that the connection is still open.
