Provide mock location data from serial to usb ublox 7020 GPS
I wanted to get a more accurate GPS fix when using google maps navigation, so I brought this: http://www.aliexpress.com/item/Hot-Wholesale-GPS-engine-board-Module-with-Antenna-USB-interface-G-Mouse-LUY-VK-162-Replace/1675335518.html
And I built this!
It creates a background service once it picks up the device and you click on the device in the device list. It uses the CdcAcmSerialDriver and sets the custom vendor and product ids. It also handles being disconnected and if the queue fails it will attempt to start again.
plug your device in
adb tcpip 4455
unplug your device
adb connect 192.168.1.103:4455
then run adb commands as usual
adb logcat
Yes you can! Create a PR with your feature!
This is a driver library for communication with Arduinos and other USB serial hardware on Android, using the Android USB Host API available on Android 3.1+.
No root access, ADK, or special kernel drivers are required; all drivers are implemented in
Java. You get a raw serial port with read(), write(), and other basic
functions for use with your own protocols.

- Latest release: v0.1.0
1. Link your project to the library.
2. Copy device_filter.xml to your project's res/xml/ directory.
3. Configure your AndroidManifest.xml to notify your app when a device is attached (see Android USB Host documentation for help).
<activity
android:name="..."
...>
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
<meta-data
android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
android:resource="@xml/device_filter" />
</activity>5. Use it! Example code snippet:
// Find all available drivers from attached devices.
UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
List<UsbSerialDriver> availableDrivers = UsbSerialProber.getDefaultProber().findAllDrivers(manager);
if (availableDrivers.isEmpty()) {
return;
}
// Open a connection to the first available driver.
UsbSerialDriver driver = availableDrivers.get(0);
UsbDeviceConnection connection = manager.openDevice(driver.getDevice());
if (connection == null) {
// You probably need to call UsbManager.requestPermission(driver.getDevice(), ..)
return;
}
// Read some data! Most have just one port (port 0).
UsbSerialPort port = driver.getPort(0);
port.open(connection);
try {
port.setBaudRate(115200);
byte buffer[] = new byte[16];
int numBytesRead = port.read(buffer, 1000);
Log.d(TAG, "Read " + numBytesRead + " bytes.");
} catch (IOException e) {
// Deal with error.
} finally {
port.close();
}For a more complete example, see the UsbSerialExamples project in git, which is a simple application for reading and showing serial data.
A simple Arduino application is also available which can be used for testing.
Sometimes you may need to do a little extra work to support devices which usb-serial-for-android doesn't [yet] know about -- but which you know to be compatible with one of the built-in drivers. This may be the case for a brand new device or for one using a custom VID/PID pair.
UsbSerialProber is a class to help you find and instantiate compatible
UsbSerialDrivers from the tree of connected UsbDevices. Normally, you will use
the default prober returned by UsbSerialProber.getDefaultProber(), which
uses the built-in list of well-known VIDs and PIDs that are supported by our
drivers.
To use your own set of rules, create and use a custom prober:
// Probe for our custom CDC devices, which use VID 0x1234
// and PIDS 0x0001 and 0x0002.
ProbeTable customTable = new ProbeTable();
customTable.addProduct(0x1234, 0x0001, CdcAcmSerialDriver.class);
customTable.addProduct(0x1234, 0x0002, CdcAcmSerialDriver.class);
UsbSerialProber prober = new UsbSerialProber(customTable);
List<UsbSerialDriver> drivers = prober.findAllDrivers(usbManager);
// ...Of course, nothing requires you to use UsbSerialProber at all: you can instantiate driver classes directly if you know what you're doing; just supply a compatible UsbDevice.
