App crashes

[dattasaurabh82]

So it is normal that first time the app crashes as it is not able to find the usb, but then when I plug in my Arduino over USB OTG and then it asks to select the app but then it crashes.

I'm running the code on Motorola Nexus
Android version: 5.1.1
processing version: 3.0.2

My Library structure:

Documents/Processing/libraries/ArduinoSerial/README.md, library.properties, library/ slf4j-android.license.txt, usb-serial-for-android.license.txt, AndroidSerial.jar, slf4j-android-1.6.1-RC1.jar, usb-serial-for-android-v010.jar

My Arduino Code:

#define NUMBER_OF_CHANNELS 8
#define PINLED1 13

volatile char lastReceivedCharFromSerialIn = '\0';

void setup() {

  pinMode(PINLED1, OUTPUT);
  Serial.begin(9600);

}

void loop() {
  digitalWrite( PINLED1, lastReceivedCharFromSerialIn == '1');
}

void serialEvent() {
  while (Serial.available()) {
    // get the new byte:
    lastReceivedCharFromSerialIn = (char)Serial.read(); 
  }
}

My Processing Code:

import com.yourinventit.processing.android.serial.*;

Serial SerialPort;
boolean Toggle;

void setup()    
{
  println(Serial.list(this));

  // this simple initialisation works only when one Serial consumer (e.g. an Arduino)
  // is connected. Serial.list provides a list with all Usb Serial devices attached
  // to this machine.
  SerialPort = new Serial(this, Serial.list(this)[0], 9600);
}

void draw()
{

}

void mousePressed() {
  Toggle = !Toggle;
  SerialPort.write( Toggle?"1":"0");
}

Device filter location:

.. projectFolder/res/xml/device_filter.xml

device_filter.xml:
