Java Question Creating my First Library

[aaronk]

Hello,

I am trying to learn how to create my first library and I have followed the video on how to do it (Basic4android Tutorial - Creating a library - YouTube).

I seem to get to the point to test it on my device but the app hangs and closes and the Log says:

LogCat connected to: B4A-Bridge: samsung GT-I9210T-359629040192745

I can't seem to work out what I have done wrong?
(think it has something to do with some class missing?)

I have attached my example to this post hoping someone might know why it's not working.
(this is my first time using eclipse, so hope I have included the correct files.)

(Whops, noticed that there is a 'Libraries developers questions' forum, maybe I should of posted this in there)

Can you upload the XML and Jar files?

 

[aaronk]

Attached are the missing XML and Jar files.

You are probably compiling with Java 7 instead of Java 6 (Android is based on Java 6).

Go to project properties -> Java Compiler -> Compiler compliance level should be set to 1.6.

Hello,

Just changed it to 1.6 and it did the job. (I was using Java 7 and not 6)

Thanks heaps.
