Avoid duplicated XML attrs

[bagipro]

Hey!

I noticed that some very obfuscated apps contain duplicated XML attributes in resources. That's why parsing of such XML documents fails.

I didn't check how Android internally handles such cases, but the code in PR only dumps only the first entry

@bagipro looks good, thanks!
Although, it will be nice if you share link to app to test this issue 🙂

Hey @skylot,

Do you want me to share it here? You can download the com.ss.android.ugc.trill app with the 33.4.1 version (https://apkcombo.com/tiktok-asia/com.ss.android.ugc.trill/download/phone-33.4.1-apk). If you open the res/layout/q6.xml. You will observe the following XML:

<p003X.C87522XaW layout_width="match_parent" layout_height="match_parent" fillViewport="true" layout_height="match_parent" layout_width="match parent">

@bagipro thank you for the sample 👍
It is really helpful sometimes to be able to check old samples for regressions, also I plan to start adding tests for resources decoder, maybe I will start with this one 🤣

Great, but there's also another bug :) You can use the same sample to reproduce it because all attributes miss the android: namespace prefix. I've reported this bug to Apktool (in case they find a solution and they did iBotPeaches/Apktool#2420), but I still didn't have enough of time to move it to Jadx :(

Oh. Ok, I will check this. I will make a new issue for that.
