Android Update 17: Why Are My External JARs Causing Runtime Errors?

Android Update 17: Resolved Incompatibility with External Jars

Android users who recently installed update 17 may have encountered class not found exceptions at run time, affecting jars such as javax.mail and apache.commons.httpclient. Despite successful compilation, the apps crashed with exceptions like "Could not find class 'javax.mail.internet.InternetAddress'".

Confronted with this issue, one should not suspect the Java update as the sole culprit. Instead, the solution lies in managing external jar dependencies.

To resolve this incompatibility, follow these steps:

1. Create a folder named "libs" within your Android project directory.
2. Copy all required external jar files into the "libs" folder.

Upon this step, Android will automatically include the jars in your build, as detailed in Android's official guide to dealing with dependencies. Consequently, your applications will run without the aforementioned exceptions.
