JAVA.IO.HWID : Use of Hardware ID (Java)

Summary

A hardware identifier is used.

This includes the following cases.

CodeSonar automatically applies this annotation to many standard Android methods. To specify additional methods to be treated as yielding a hardware identifier, apply this annotation directly.

Warnings of this class are not issued inside exception handlers that catch a GooglePlayServicesNotAvailableException, since a device identifier could be needed to handle this exception (e.g., to give feedback to the developer).
