Here is your problem:
Code:
java.lang.NoClassDefFoundError: java.lang.StringBuilder
You are obviously building the project with the wrong settings. The Kindle is Java 1.4, and that class doesn't exist in 1.4. Fix your project settings to compile with a target version of 1.4.
Some more background: this is a classic actually (and it happened to me too, more than once
). The problem here is String concatenation. String s = "x"+"y"; is internally "resolved" by instantiating a StringBuilder (>= Java 5), or a StringBuffer ( <= Java 1.4).
StringBuilder was introduced in Java 1.5 as a more performant drop-in replacement for the (Thread-safe, and thus less performant) StringBuffer class.
