Recently started getting a rather odd Catlog which doesn't describe what's going wrong very well.
I have it posted here: http://pastie.org/9415113
Line 55:
DebugCarTxt = (EditText) findViewById(R.id.DebugCar);
// you should instantiate 'DatabaseHandler' here
DatabaseHandler db = new DatabaseHandler(this); // "this" refer to the context
Car cars = db.getCurrentCar();
db.createCar(new Car(cars.get_id(),cars.get_address(),cars.get_postcode(),cars.get_image()));
//this is line 55 String rows= "id : "+ cars.get_id()+ " address : "+cars.get_address() + "postcode : "+cars.get_postcode()+" image : "+cars.get_image();
This is my getCurrentCar() {};
public Car getCurrentCar() {
SQLiteDatabase db = getWritableDatabase();
String sql = "SELECT " + KEY_ID + "," + KEY_IMAGE + " FROM " + TABLE_CARS + " ORDER BY RANDOM() LIMIT 1";
Cursor cursor = db.rawQuery(sql, new String[] {});
Car car = null;
try {
if (cursor.moveToFirst()) {
car = new Car(Integer.parseInt(cursor.getString(0)), cursor.getString(1), cursor.getString(2), cursor.getString(3));
}
}
finally {
if (cursor != null && !cursor.isClosed()) {
cursor.close();
}
db.close();
}
return car;
}
Am I right to assume it's calling a null because there isn't anything in the database?

One of the values you are getting is set as null.
Edit: MY fault, I believe that it is the Car that is null. You should check if there are any values set as null by:
if(car == null) { //and etc for other get method.
//Use Logs here to print error on logcat.
}
This should help identifying which value is null.
