Same here. I have links in a local html file referencing file:///android_res/drawable/ and on all gradle build flavors using another applicationId (added suffix) the Webview only shows broken links.

This behaviour seems not to be connected solely to Android 5.0 since it occurs on Android 4.4.4 too (tested with current cyanogenmod 11 build).

As a hotfix I added the following code to the gradle buildscript, which generates an additional R.java with changed java package for every flavor. I don't like this solution though.

android.applicationVariants.all{ variant ->
  variant.javaCompile.doFirst{
   copy {
        from "${buildDir}/generated/source/r/${variant.dirName}/com/example/application/R.java"
        into "${buildDir}/generated/source/r/${variant.dirName}/com/example/application/${variant.buildType.name}/"
    }
    File rFile = file("${buildDir}/generated/source/r/${variant.dirName}/com/example/application/${variant.buildType.name}/R.java")
    String content = rFile.getText('UTF-8')
    String newPackageName = "com.example.application.${variant.buildType.name}";
    content = content.replaceAll(/com.example.application/, newPackageName)
    rFile.write(content, 'UTF-8')
  }
}

I've recenly encountered this issue and I must say it's quite a nuisance. Searched half of the Internet just to find out that the problem lies in Gradle's applicationIdSuffix :). I think this bug should be reported to Android SDK Build Tools devs, because only they can do something about it.

IMHO it's the case of Android platform problem. Resources are packed, WebView tries to load them from wrong place. It's not build tools that put them in wrong place.

And by the way it's very frustrating bug.
