Processing et Android

Bonjour,
j'ai un petit soucis avec le mode android de processing, j'ai bien installé les sdk demandés. Cependant j'ai effectué un test, avec très peu de commande, mais j'ai une erreur lors du démarrage de l'application. Si quelqu'un sait à quoi ça correspond.
Mon code :

void setup()
{
  size(displayWidth, displayHeight);
  background(0);
}

void draw()
{
  fill(204, 102, 0);
  rect(30, 20, 55, 55);
  text("hello Android + Processing", 100, 100);
}

L'erreur affichée :
