Monkey April 2024 #2

Closed baltpeter closed 4 months ago

baltpeter commented 5 months ago

Since it's been almost a year since our last collection (#1), I think it's time to do another run to get a sense of whether there've been any significant changes since then (especially new endpoints).

The goal is once again to gather as many requests to many different endpoints as possible, so I'll do another monkey test run.

baltpeter commented 5 months ago

To get this done quickly, I'll only do Android for now and reuse the existing code from #1.

google/googleplay didn't end up working for me this time, so I used apkeep, cf.: https://github.com/tweaselORG/meta/issues/46#issuecomment-2079016960

baltpeter commented 5 months ago

Oh no. None of the apps I downloaded using apkeep seem to want to start. I've tested both an Android 11 x86_64 emulator and Android 13 arm64 physical device. They either crash immediately after launching or show an error like this:

I thought that maybe the fact that I was using -o device=px_7a was the problem, since I'm not actually trying to run the apps on a Pixel 7a. But that doesn't seem to be the case, either.

Both apkeep (https://github.com/EFForg/rs-google-play/blob/31342793e3aab28e9c24ef00372e350e406884e1/gpapi/device.properties) and the Android emulator support Pixel 3a, so I tried that. Same problem.

Was the app downloaded for the wrong architecture?

baltpeter commented 5 months ago

If I'm seeing this correctly, the APK doesn't include any native code at all. o.o

❯ aapt dump badging org.telegram.messenger.apk | grep native-code

Whereas, if I download the same APK from APKMirror, there are native binaries:

❯ aapt dump badging org.telegram.messenger_10.12.0-47101_minAPI19\(armeabi-v7a\)\(nodpi\)_apkmirror.com.apk | grep native-code
native-code: 'armeabi-v7a'

Oh wow, looks like I misinterpreted the documentation for the split_apk option:

split_apk: when set to 1 or true, attempts to download a split APK

I thought that meant that it would merge the splits into a single APK when the option is not provided (like google/googleplay does, for example). But, no. Looks like it just downloads the main APKs and completely ignores the splits in that case.

If I download the app with splits and install that, it works fine.

❯ apkeep -d google-play -o device=px_3a,locale=en_DE,include_additional_files=1,split_apk=1 -a org.telegram.messenger .
❯ ls org.telegram.messenger
org.telegram.messenger.apk                   org.telegram.messenger.config.en.apk
org.telegram.messenger.config.arm64_v8a.apk  org.telegram.messenger.config.xxhdpi.apk
❯ adb install-multiple org.telegram.messenger/*.apk
Success
