Class WrongImportDetector

java.lang.Object

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

com.android.tools.lint.checks.WrongImportDetector

All Implemented Interfaces:

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

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

Checks for "import android.R", which seems to be a common source of confusion (see for example http://stackoverflow.com/questions/885009/r-cannot-be-resolved-android-error and many other forums).

The root cause is probably this (from http://source.android.com/source/using-eclipse.html) :

Note: Eclipse sometimes likes to add an import android.R statement at the top of your files that use resources, especially when you ask eclipse to sort or otherwise manage imports. This will cause your make to break. Look out for these erroneous import statements and delete them.
