Fixing errors in Android Java applications
This document discusses several Java programming topics including raw type parameters, working with the Java compiler, logging, and static analysis. It describes common Java problems like raw types and demonstrates how to address them. It also shows how to configure Java compiler preferences for tighter type checking and how logging and static analysis can help find bugs.
