Arbitrary resource names with periods cause failure to reassemble

[gizmaniac]

Information

1. Apktool Version (apktool -version) - 2.3.4
2. Operating System (Mac, Linux, Windows) - Linux
3. APK From? (Playstore, ROM, Other) - Sample app demonstrating problems in other apps

Stacktrace/Logcat

I: Building resources...
W: /root/Desktop/test/dottednametest/res/values/arrays.xml:3: error: Error retrieving parent for item: No resource found that matches the given name 'com.sampleapp.arrays.init'.

Steps to Reproduce

1. Create a dummy sample app that includes a resource using periods in the name, as such: One.1 Two.2 Three.3 Four.4 Five.5
2. Disassemble the app with apktool d and try to reassemble with apktool b, and it will fail.

It appears the reassembly presumes that because the resource name contains periods in the string, that it is part of some hierarchy (i.e. has a parent), when in fact it is nothing more than an arbitrary name. This name IS allowed when building in Android Studio.

APK

Sorry, initial post didn't properly demonstrate the resource name:

<string-array name="com.sampleapp.arrays.init.values">

testapp-orig/res/values-mcc001/arrays.xml:38: error: Error retrieving parent for item: No resource found that matches the given name 'values.issue'.

Confirmed with new test example. What a weird bug.

Hi all, just a small note, that this nasty issue is still reproducible.

Yes, I confirm this bug is still present

As a workaround, assuming you don't need to mess around with resources, when decompiling use -r option: apktool d -r some.apk It won't touch them and leave in raw state.
