Android update 17 seems incompatible with external Jars
android, java, macos
Solution
crash at run time with exceptions that look like this: `Could not find class 'javax.mail.internet.InternetAddress', referenced from method com.my.project.Main.isValidEmailAddress`
If you have problems with external jars, then:
- create a folder named `libs`.
- Copy and paste all needed external jar files into that folder.
It will automatically be included, as explained on this page: Dealing with dependencies in Android projects
Problem
I just allowed my Mac to do an update on its Java installation and now some of my old jars (like `javax.mail` and `apache.commons.httpclient`) are throwing "class not found" exceptions at run time! Meaning, they compile fine, but then crash at run time with exceptions that look like this: ``` E/dalvikvm(2414): Could not find class 'javax.mail.internet.InternetAddress', referenced from method com.my.project.Main.isValidEmailAddress ``` Do I need to get more recent versions of the jars that have those classes? Or do I need to revert to my previous version of Java? Or is this some totally unrelated problem that I'm just assuming has to do with the Java update (would be quite a coincidence, all of this worked perfectly prior to the update)?
