I'm trying to do some simple FTP stuff in Android. After researching a little bit, I decided to go with the apache-commons-net. Here are the steps I took to get it working under Eclipse.
- Downloaded the package from here and unpacked it locally.
- In Eclipse, to add this new library, I go to (Window >) Preferences > Java > Build Path > User Libraries, click New, name it
apache-commons-net
, then Add JARs... to it by picking the .jar files that came in the download. - For each .jar, I add in the Source attachment as described here.
- Once this is done, I right-click my project and choose Properties > Java Build Path > Libraries, click Add Library... > User Library > (Next >) choose
apache-commons-net
> Finish. The library then shows up alongsideAndroid 2.2
in the Libraries tab.
I start programming, and code completion works fine for the classes/methods/etc. from this library. Import statements are included, etc. Everything seems to work as it should. The problem is, when I run the app, it force closes and my LogCat in Eclipse shows the following error:
Could not find class 'org.apache.commons.net.ftp.FTPClient', referenced from method <...>
...
Caused by: java.lang.NoClassDefFoundError: org.apache.commons.net.ftp.FTPClient
It seems like I've set everything up correctly, so why is the execution complaining that it can't find the class???
Any ideas or help is greatly appreciated.
