Java help needed please

[Guest Navie]

Does anyone know how to fix this please? I downloaded SDK and then used Eclipse for app development

The error is caused by something I use, if that's important I can state what it is but don't feel it is at the moment.

Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger

Hi Navie,

This error means the code you use needs Log4J library - link

Anyway I do not think it is a common practice to use it in mobile development, it's created for Java SE/EE
