IllegalStateException parsing APKs with no resource table. In AGP 7, android-test APKs will have no resource table if androidTest/res is empty

[autonomousapps]

In AGP 7, if you execute (e.g.)

./gradlew lib:assembleDebugAndroidTest

on an Android library project that doesn't have any resources (no androidTest/res directory), and then attempt to compare that APK with one built with AGP 4, you'll get an error like this:

$ diffuse diff --apk test4.apk test7.apk
Exception in thread "main" java.lang.IllegalStateException: ResourceTableChunk package count was < 1.

Note that this issue arises regardless of whether the library project uses

android.buildFeatures.androidResources = false

That value appears to be ignored, at least in AGP 7.0.3. The mere presence of a resource in androidrTest/res can workaround this issue.

apktool has a similar issue when executing apktool d path/to/apk -o foo, but there's a CLI option, -r, that solves the problem: apktool -r d path/to/apk -o foo.

I don't think this is related to diffuse... are you sure you've submitted an issue on the repository you wanted?

[autonomousapps]

oh dear god this is the wrong diffuse. I am SO sorry. (hope you get a laugh, though)

[MightyCreak]

Hahaha no worries :wink: You got me puzzled though :sweat_smile:
