android-resource-shrinker

[tiann]

used proguard to find unused class: usage.txt contains deleted files.

[tiann]

lint seems can not found cross-module referenced unused resource; the default proguard file of android keep all fields of R class; so we can not distinguish the unused resource correctly??

[tiann]

proguard to found unused class:

-dontoptimize
-dontobfuscate
-dontpreverify
-printusage

source code of shrinkResource

[tiann]

can not use shrinkReleaseResources directly, this task is added dynamicly, we can only access it after the gradle scripts are evaluated:

afterEvaluate { project ->
    project.tasks.shrinkReleaseResources << {
    doSomeThing()
}

[tiann]

we can debug gradle plugin, use remote debugger:

how to get all resource the project depends on?

[tiann]

get all project: project.rootProject.subprojects

and android is just a ext property of project, we can access like this:

module.extensions.findByName("android")
