How to run the sketch in Android mode.

Hello,

i made the following sketch to communicate with my arduino. The sketch is running fine in java mode but my goal is to run the sketch on my phone:

import processing.serial.*;
Serial myPort; // Objekt der Serial-Klasse
char HEADER = 'H'; // Zeichen zur Identifikation des Anfangs einer Nachricht
short LF = 10; // ASCII-Linefeed
float kmhArduino;
int distArduino;
int siebenArduino;
PFont font;
short portIndex = 0; // com-Port wa¨hlen, 0 ist der erste Port

void setup() {
  size(480, 800);
  font = loadFont ("Arial-BoldMT-48.vlw");
  println(Serial.list());
  println(" Verbinde mit -> " + Serial.list()[portIndex]);
  myPort = new Serial(this, Serial.list()[portIndex], 9600);
}
void draw() {
  background(0, 0, 50);
  fill(255, 0, 0);
  textFont(font, 48);
  text("Sk8tacho V1.0", 50, 100);
  textFont(font, 40);
  fill(255, 255, 0);
  text(kmhArduino + "kmh", 100, 300);
  text("Distance: " + distArduino + "m", 50, 400);
  fill(255, 0, 0);
  textFont(font, 30);
  text("made by inventED 2015", 50, 700);
  }
void serialEvent(Serial p)
{
  String message = myPort.readStringUntil(LF); // Serielle Daten einlesen
  if (message != null)
  {
    print(message);
    String [] data = message.split(","); // Kommaseparierte Nachricht zerlegen
    if (data[0].charAt(0) == HEADER && data.length > 3) // check validity
    {
      kmhArduino = float(data[1]);
      distArduino = int(data[2]);
      //siebenArduino = int(data[7]); // falls mehr werte gebraucht werden
    }
  }
}

i already tried to convert it to android mode. but when i switch to android mode i get this errors in the console:

Exception in thread "Thread-126" java.lang.NullPointerException
    at processing.mode.android.AndroidBuild.setSdkTarget(AndroidBuild.java:76)
    at processing.mode.android.AndroidEditor.updateSdkMenu(AndroidEditor.java:347)
    at processing.mode.android.AndroidEditor.access$300(AndroidEditor.java:50)
    at processing.mode.android.AndroidEditor$7.run(AndroidEditor.java:249)

Here is my converted android mode code:

//import processing.serial.*;
//Serial myPort;
import android.os.Bundle;
import ketai.net.bluetooth.*;
KetaiBluetooth bt;

char HEADER = 'H'; // Zeichen zur Identifikation des Anfangs einer Nachricht
short LF = 10; // ASCII-Linefeed
float kmhArduino;
int distArduino;
int siebenArduino;
PFont font;
short portIndex = 0; // com-Port wa¨hlen, 0 ist der erste Port

void setup() {
  size(480, 800);
  font = loadFont ("Arial-BoldMT-48.vlw");
  /*println(Serial.list());
  println(" Verbinde mit -> " + Serial.list()[portIndex]);*/
  //myPort = new Serial(this, Serial.list()[portIndex], 9600);
  bt.start(); // BT Service starten.
  //***************************************************************
  // Hier muss die individuelle Adresse deines BT Moduls eingegeben werden.
  bt.connectDevice("98:D3:31:30:2C:04"); // HC-05 BT-Modul
  //bt.connectDevice("00:13:01:06:20:83"); // HC-05 BT-Modul
  //bt.connectDevice("00:11:12:11:04:73"); // BT-Shield Arduino

      distArduino = int(data[2]);
      //siebenArduino = int(data[7]); // falls mehr werte gebraucht werden
    }
  }
}

when i try to run the sketch i get this error in the console:

BUILD FAILED
C:\Users\ED\Documents\Processing\modes\AndroidMode\sdk\tools\ant\build.xml:538: Unable to resolve project target 'android-15'

Total time: 0 seconds

Would be really cool if anybody can help me out!! I´m pretty new to coding and processing, sorry if something is not clear.

I´m using Windows 7 64-bit, tried Processing 3.0.2 windows 64-bit version and 32-bit version.

Thank you!
