In my android project, I use a external jar which will use the class
Here is the error information:
06-13 02:45:18.586: ERROR/dalvikvm(228): Could not find class 'javax.activation.MimetypesFileTypeMap', referenced from method weibo4j.http.HttpClient.multPartURL
Who can tell me why this happened?
The
javax.activationpackage is not part of the Android core (as you can see, it’s not in the package index), so you will not be able to use that Jar without a recompiledjavax.activationjar (if there is one at all). What does this external Jar do?
