I've never programmed in Java before and I'm new to Kindle development, so I was wondering if this was something with my code or the JAR files? (My Kindle 3G stopped receiving updates long ago).
Thank you so much! |
I'm guessing you just tried to compile it with whatever java version you are using on your desktop, which won't work. I believe the version you want to target is java 1.4 for K3, though if you have jailbreak access you can try checking the java version by running
Code:
/usr/java/bin/cvm -version
For example on my PW2 at the end of the output:
Code:
java version "1.8.0_211-ea"
Java(TM) SE Embedded Runtime Environment (build 1.8.0_211-ea-b00, profile compact1, headless)
Java HotSpot(TM) Embedded Minimal VM (build 25.211-b00, mixed mode)
It looks like you are using ant to build the project so add these properties to tell it to compile for java 1.4
Code:
<property name="ant.build.javac.source" value="1.4"/>
<property name="ant.build.javac.target" value="1.4"/>
Also in your manifest file, you have the line
Code:
SDK-Specification-Version: 2.1
but this needs to be <= whatever Kindlet-x.x.jar version is on your kindle (So change it to 1.0 or 1.2)
