array parsing in resources #1994
Comments

Can you please give me a quick link to the location where the Snapshot builds can be obtained from @azt59? I had recently lost the link and had just remembered about asking around for it again. Thanks a bunch! :-) ~Ibuprophen |

I build it by this instructions https://ibotpeaches.github.io/Apktool/build/ |
|
This case is present too in 2.3.4 version, arrays is parsed as styles tags |
|
Confirmed. |

Hi! I have just ran into the same issue, I spent some times trying to implement a fix and found this solution: diff --git a/brut.apktool/apktool-lib/src/main/java/brut/androlib/res/data/ResTypeSpec.java b/brut.apktool/apktool-lib/src/main/java/brut/androlib/res/data/ResTypeSpec.java

Instead of using the id of the first item within the bag, I use the name of the res type spec to choose the res bag value to create. The "names" have been found from the aapt2 source code: I kept the previous checks, but we might remove them and use only the check on the names. Please, feel free to tell me what you think of the solution :) I might submit an MR in the coming days if it's OK for you! |

@vbarthel-fr That sounds excellent! Thanks for digging into that. I always knew trusting the first value inside the bag was a bad idea. Your solution looks good. Feel free to put it up for review |
|
@iBotPeaches Thanks :) Before I submit a pull request, have you any preferences regarding keeping the previous checks? I might not have enough hindsight and experience with the arsc format to fully understand the consequences of those changes! |

Here is my first attempt: #2000 :) |
