Class ServiceCastDetector

java.lang.Object

com.android.tools.lint.detector.api.Detector

com.android.tools.lint.checks.ServiceCastDetector

All Implemented Interfaces:

com.android.tools.lint.detector.api.FileScanner, com.android.tools.lint.detector.api.SourceCodeScanner

public class ServiceCastDetector
extends com.android.tools.lint.detector.api.Detector
implements com.android.tools.lint.detector.api.SourceCodeScanner

Detector looking for casts on the result of context.getSystemService which are suspect.

TODO: As of O we can start looking for the @SystemService annotation on the target interface class, and the value attribute will map back to the expected constant. This should let us get rid of the hardcoded lookup table below.
