Function:
BOOL AndroidAppIsReadComplete_Pv1(void* handle, BYTE* errorCode, DWORD* size)
Summary:
Check to see if the last read to the Android device was completed
Description:
Check to see if the last read to the Android device was completed. If
complete, returns the amount of data that was sent and the corresponding
error code for the transmission.
Precondition:
Transfer has previously been requested from an Android device.
Parameters:
void* handle - the handle passed to the device in the EVENT_ANDROID_ATTACH event
BYTE* errorCode - a pointer to the location where the resulting error code should be written
DWORD* size - a pointer to the location where the resulting size information should be written
Return Values:
TRUE - Transfer is complete.
FALSE - Transfer is not complete.
Remarks:
Possible values for errorCode are:
* USB_SUCCESS - Transfer successful
* USB_UNKNOWN_DEVICE - Device not attached
* USB_ENDPOINT_STALLED - Endpoint STALL'd
* USB_ENDPOINT_ERROR_ILLEGAL_PID - Illegal PID returned
* USB_ENDPOINT_ERROR_BIT_STUFF
* USB_ENDPOINT_ERROR_DMA
* USB_ENDPOINT_ERROR_TIMEOUT
* USB_ENDPOINT_ERROR_DATA_FIELD
* USB_ENDPOINT_ERROR_CRC16
* USB_ENDPOINT_ERROR_END_OF_FRAME
* USB_ENDPOINT_ERROR_PID_CHECK
* USB_ENDPOINT_ERROR - Other error

Summary:
Checks to see if the last command request is complete.
Description:
Checks to see if the last command request is complete.
Precondition:
AndroidAppStart() function has been called before the first calling of this function
Parameters:
BYTE address - the address of the device that issued the command
BYTE* errorCode - pointer to the location where the error code should be stored
DWORD* byteCount - pointer to the location where the size of the resulting transfer should be written.
Return Values:
TRUE - command is complete
FALSE - command is still in progress
Remarks:
This function is implemented for polled transfer implementations but should
be deprecated once polled transfer requests are removed.
Internal API only. Should not be called by a user.
