This is a duplicate to: b/170538201 and b/389707035

And b/389707035 seems to provide a workaround in the platform for this but haven't been reviewed yet. Filing this just to raise some awareness on this. Any workaround in the library/end-user level is appreciated

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')
}
}
