Arduino 1.0.3 Errors

Using Arduino Programming Questions
1

Hi,

I bought an Arduino Mega ADK , and try to make simple sketch using the Arduino IDE.

But when I compile I get this message :

C:\Users\BipBip\Downloads\arduino-1.0.3-windows\arduino-1.0.3\libraries\UsbHost/AndroidAccessory.h: In function 'void setup()':
C:\Users\BipBip\Downloads\arduino-1.0.3-windows\arduino-1.0.3\libraries\UsbHost/AndroidAccessory.h:68: error: 'void AndroidAccessory::powerOn()' is private
sketch_jan11a:16: error: within this context
C:\Users\BipBip\Downloads\arduino-1.0.3-windows\arduino-1.0.3\libraries\UsbHost/AndroidAccessory.h: In function 'void loop()':
C:\Users\BipBip\Downloads\arduino-1.0.3-windows\arduino-1.0.3\libraries\UsbHost/AndroidAccessory.h:66: error: 'int AndroidAccessory::read(void*, int, unsigned int)' is private
sketch_jan11a:23: error: within this context

I don't know what I can do to resolve this problem.

There is my AndroidAccessory.cpp :

}

boolean AndroidAccessory::begin(void) {
  powerOn();
  return true; // For forward compatibility with v2.x of the library
}

void AndroidAccessory::powerOn(void)
{
    max.powerOn();
    delay(200);
}

There is more code , but nothing important...

Can you give me a way to clear these problems ?

try to make simple sketch using the Arduino IDE.

But when I compile I get this message :

There is my AndroidAccessory.cpp :

Which .cpp file is compiling when the errors occur? It may not be the AndroidAccessory.cpp library implementation - perhaps it's a problem in the sketch itself. Which we can't see yet, by the way.

There is the sketch :

#include <Max3421e.h>
#include <Usb.h>
#include <AndroidAccessory.h>
#define  LED_PIN  13
AndroidAccessory acc("Manufacturer",
		"Model",
		"Description",
		"1.0",
		"http://yoursite.com",
                "0000000012345678");
void setup()
{
  // set communiation speed
  Serial.begin(115200);
  pinMode(LED_PIN, OUTPUT);
  acc.powerOn();
}

void loop()
{
  byte msg[0];
  if (acc.isConnected()) {
    int len = acc.read(msg, sizeof(msg), 1); // read data into msg variable
    if (len > 0) {
      if (msg[0] == 1) // compare received data
        digitalWrite(LED_PIN,HIGH); // turn on light
      else
        digitalWrite(LED_PIN,LOW); // turn off light
    }
  } 
  else
    digitalWrite(LED_PIN , LOW); // turn off light
}

I think the AndroidAccesory.h included at the top uses the .cpp , no ?

What you can do is not use those private functions.
