Class ShadowUsbDeviceConnection

java.lang.Object
org.robolectric.shadows.ShadowUsbDeviceConnection

@Implements(android.hardware.usb.UsbDeviceConnection.class) public class ShadowUsbDeviceConnection extends Object
Robolectric implementation of UsbDeviceConnection.

      public ShadowUsbDeviceConnection()
  • Method Details

    • claimInterface

      @Implementation protected boolean claimInterface(UsbInterface intf, boolean force)
    • releaseInterface

      @Implementation protected boolean releaseInterface(UsbInterface intf)
    • setInterface

      @Implementation protected boolean setInterface(UsbInterface intf)
      No-op on Robolectrict. The real implementation would return false on Robolectric and make it impossible to test callers that expect a successful result. Always returns true.
    • controlTransfer

      @Implementation protected int controlTransfer(int requestType, int request, int value, int index, byte[] buffer, int length, int timeout)
    • controlTransfer

      @Implementation protected int controlTransfer(int requestType, int request, int value, int index, byte[] buffer, int offset, int length, int timeout)
    • requestWait

      @Implementation protected UsbRequest requestWait()
    • requestWait

      @Implementation(minSdk=26) protected UsbRequest requestWait(long timeout) throws TimeoutException
      Throws:
      TimeoutException
    • bulkTransfer

      @Implementation protected int bulkTransfer(UsbEndpoint endpoint, byte[] buffer, int offset, int length, int timeout)
    • bulkTransfer

      @Implementation protected int bulkTransfer(UsbEndpoint endpoint, byte[] buffer, int length, int timeout)
    • readOutgoingData

      @Deprecated public void readOutgoingData(byte[] buffer) throws IOException
      Deprecated.
      prefer getOutgoingDataStream(), which allows callers to know how much data has been read and when the UsbDeviceConnection closes.
      Fills the buffer with data that was written by UsbDeviceConnection#bulkTransfer.
      Throws:
      IOException
    • getOutgoingDataStream

      public InputStream getOutgoingDataStream()
      Provides an InputStream that allows reading data written by UsbDeviceConnection#bulkTransfer. Closing this stream has no effect. It is effectively closed during UsbDeviceConnection.releaseInterface(UsbInterface).
    • writeIncomingData

      public void writeIncomingData(byte[] data)
      Passes data that can then be read by an initialized UsbRequest#queue(ByteBuffer).
