Yamba app not working.

Well i am using Gingerbread to create the yamba app. The problem is coming in "Try and Catch"

if i run this code without the try and catch it works perfectly.

This shows some problem in jtwitter.. somehow it cant detect the jwitter classes
although i did import all:


CAN YOU HELP ME ON THIS?

Have you tried to re-build your app (Project -> Clean) and re-run it?

Yes i did try the (Project -> clean) it still gives me the same error.

Hmm... try removing all org.json.* classes from the twitter.jar file, re-add it to your Eclipse project and try again.

I have the same problem,It wouldnt detect the com.winterwell.jtwitter and forces the DVM to close immediately.(As seen in logcat) My Yamba was worjing well before the jtwitter was imported..Also at the
textCount=(Edittext) findViewbyId(R.id.textCount) There is always an error saying textcount cant be resolved...I use the latest adt for eclipse and I downloaded the new "jtwitter-yamba.jar"

while running yamba app i got this error

If you are using ADT r17 (android 4.2) then you should no longer add library files to your project like this. This is now handled automatically by ADT.

In order to add an external library to your project you have to create a folder called libs in the root folder of your project (the folder where your src folder is located). The next step is to copy all jar libraries like jtwitter-yamba.jar to that folder. The rest is done automatically for you. No need to edit build path, etc.

Moving jtwitter-yamba.jar file to libs folder resolve Fatal Error for me.
