Pre-releaseVersion: 0.1.0
Release date: November 13, 2012
Notes: First public release of usb-serial-for-android.
Quick Start
1. Download usb-serial-for-android-v010.jar
2. Copy the jar to your Android project's libs/
directory. (See Android's FAQ for help).
3. Copy device_filter.xml to your project's res/xml/
directory.
4. 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:
// Get UsbManager from Android.
UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
// Find the first available driver.
UsbSerialDriver driver = UsbSerialProber.acquire(manager);
if (driver != null) {
driver.open();
try {
driver.setBaudRate(115200);
byte buffer[] = new byte[16];
int numBytesRead = driver.read(buffer, 1000);
Log.d(TAG, "Read " + numBytesRead + " bytes.");
} catch (IOException e) {
// Deal with error.
} finally {
driver.close();
}
}
For a more complete example, see the UsbSerialExamples/
project, which is a simple application for reading and showing serial data.
A simple Arduino application is also available (in arduino/
), which can be used for testing.
