{"text": "<|im_start|>user\nYou are a Singularity-Level AI. Analyze this file from the 'APKTOOL' repository. Explain the technical logic, security implications (offensive/defensive), or financial algorithm involved.\nFile: INTERNAL.md\n<|im_end|>\n<|im_start|>assistant\nREPO: APKTOOL\nCODE:\n# Releasing a new version.\n\nThe steps taken for slicing an official release of Apktool.\n\n### Ensuring proper license headers\n\n_Currently broken after movement to kotlin dsl._\n\n### Tagging the release.\n\nInside `build.gradle` there are two lines.\n\n    version\n    suffix\n\nThe version variable should be left unchanged. If done correctly, it will already be the version\nyou are about to release. In this case `2.2.2`. The suffix variable should read `SNAPSHOT` as\nthe `2.2.2` release up until this point was `SNAPSHOT` releases (Unofficial).\n\nWe need to remove the `SNAPSHOT` portion and leave the minor version blank. An example can be\nfound [here](https://github.com/iBotPeaches/Apktool/commit/96b70d0be7513c5a1e5d3a3b9a75e4e2b076ad79).\n\nAfter we remove `SNAPSHOT` we need to make the version commit. Organization and following patterns\nis crucial here. This commit should have 1 change only - the change above. Now commit this change\nwith the commit message - `version bump (x.x.x)`.\n\nAt this point we now have the commit of the release, but we need to tag it using the following message.\n\n    git tag -a vx.x.x -m \"changed version to vx.x.x\" -s\n\nFor example for the `2.2.1` release.\n\n    git tag -a v2.2.1 -m \"changed version to v2.2.1\" -s\n\n### Prepare for publishing.\n\nNew to Apktool is publishing releases to Maven, so plugin authors can directly integrate. You\nneed a `gradle.properties` file in root with the structure:\n\n```\nsigning.keyId={gpgKeyId}\nsigning.password={gpgPassphrase}\nsigning.secretKeyRingFile={gpgSecretKingRingLocation}\n\nossrhUsername={sonatypeUsername}\nossrhPassword={sonatypePassword}\n```\n\nRelease with maven with `./gradlew build shadowJar release publish`.\n\n### Building the binary.\n\n> [!IMPORTANT]\n> In order to publish Maven artifacts you need JDK 11+.\n\nIn order to maintain a clean slate. Run `gradlew clean` to start from a clean slate. Now lets build\nthe new binary version. We should not have any new commits since the tagged commit.\n\n    ./gradlew build shadowJar proguard release\n\nThe build should tell you what version you are building, and it should match the commits you made previously.\n\n    \u279c Apktool git:(main) ./gradlew build shadowJar proguard release\n    Building RELEASE (main): 2.2.2\n\n### Testing the binary.\n\nNow the release binary is built in the same location as all other builds. Run this version against\nsome of the fixed bugs in this release. This is a simple test to ensure the build had no errors.\n\nCopy the jar to any location to prep for uploading. The pattern we name the jars is\n\n    apktool_x.x.x.jar\n\nOr in the case of the last release - `apktool_2.2.1.jar`\n\nOnce you have the jar in this form. Record the md5 hash & sha256 hash of it. This can be done using `md5sum`\nand `sha256sum` on unix systems.\n\nThis can be shown for the `2.2.2` release like so\n\n    \u279c  Desktop md5sum apktool_2.2.2.jar\n    1e6be08d3f9bb4b442bb85cf4e21f1c1  apktool_2.2.2.jar\n\n    \u279c  Desktop sha256sum apktool-2.2.2.jar\n    1f1f186edcc09b8677bc1037f3f812dff89077187b24c8558ca2a89186ea3251  apktool-2.2.2.jar\n\nRemember these hashes. These are the local hashes. These are our main hashes. All others (Bitbucket, Backup)\nmust match these. If they do not - they are invalid.\n\n### Lets get uploading.\n\nLets make sure we actually pushed these release changes to the repo (Both Github & Bitbucket)\n\n    git push origin main\n    git push origin vx.x.x\n\n    git push bitbucket master\n    git push bitbucket vx.x.x\n\nWe upload the binaries into 3 places.\n\n1. [Bitbucket Downloads](https://bitbucket.org/iBotPeaches/apktool/downloads)\n2. [Github Releases](https://github.com/iBotPeaches/Apktool/releases) - Since `2.2.1`.\n3. [Backup Mirror](https://connortumbleson.com/apktool/)\n4. [Sonatype (Maven)](https://oss.sonatype.org)\n\n#### Bitbucket\n\nThis one is pretty easy. Head to the URL attached to the hyperlink #1 above. There will be a \"Add Files\"\nbutton on the top right of the page. Upload the `apktool_x.x.x.jar` file.\n\nAfter it is uploaded. Immediately visit the page and download it. Check the `md5` for a match.\n\n#### GitHub\n\nThis option will not work until the tag is pushed. You can head to this [page](https://github.com/iBotPeaches/Apktool/releases/new)\nto draft a new release. The `Tag version` dropdown will have the new tag. In this case `v2.2.2`.\n\nSelect that option and make the title `Apktool vx.x.x`. There will be a description field on this release.\nHold tight, we link the release blog post in this field, but we can edit the release after the fact to add this.\n\nUpload the binary `apktool_x.x.x.jar` and submit the release.\n\n#### Backup Server\n\nAccess to this server is probably limited so this option may not be possible. SSH into the\n`connortumbleson.com` server with username `connor`. Head to `public_html/apktool` and upload\nthe `apktool_x.x.x.jar` to it.\n\nNow re-generate the md5/sha256 hashes for these files.\n\n    md5sum *.jar > md5.md5sum\n    sha256 *.jar > sha256.shasum\n\nCheck the `md5.md5sum` file for the hashes. The file will look something like this.\n\n    6de3e097943c553da5db2e604bced332  apktool_1.4.10.jar\n    ...\n    1e6be08d3f9bb4b442bb85cf4e21f1c1  apktool_2.2.2.jar\n\nAdditionally check the `sha256.shasum` file for the hashes. This file will look almost identical to the above\nexcept for containing sha256 hashes.\n\nThe hashes match so we are good with the backup server.\n\n#### Sonatype\n\nYou'll want to log in and view the Staging repositories and confirm you see the recently made build. You'll want to:\n\n * Close it (Wait for audit report email)\n * Release it (Drop the staging repository)\n * Wait 20min - 2 hours for it to appear [here](https://mvnrepository.com/artifact/org.apktool/apktool-lib)\n\nWith those done, time to get writing the release post.\n\nWe currently blog the releases on the [Connor Tumbleson personal blog](https://connortumbleson.com/).\nThis may change and the formatting of these release posts change over time.\n\nSome recent releases for understanding the pattern can be found below.\n\n1. [2.2.1](https://connortumbleson.com/2016/10/18/apktool-v2-2-1-released/)\n2. [2.2.0](https://connortumbleson.com/2016/08/07/apktool-v2-2-0-released/)\n3. [2.0.2](https://connortumbleson.com/2015/10/12/apktool-v2-0-2-released/)\n4. [2.0.0](https://connortumbleson.com/2015/04/20/apktool-v2-0-0-released/)\n\nFor obtaining commit authors and counts. The following command does the legwork:\n\n    git shortlog -s -n --all --no-merges --since=\"05 Sept 2018\"\n\nObviously replacing the date with the release date of the last version.\n\nSo write the post. I tend to always include the following:\n\n1. Image of release for featured image when reshared on socials.\n2. Quick sentence or two for SEO to describe the meat of this release.\n3. Commit count and total for this release with author names.\n4. Changelog linking to the bugs that were fixed.\n5. Download including the md5/sha256 hash.\n6. Link dump to Project Site, GitHub, Bug Tracker and XDA Thread.\n\nNow that you've written this post. We need to go post it in places and update places where\nApktool is released.\n\n### XDA Thread\n\nWe have a [thread](https://forum.xda-developers.com/showthread.php?t=1755243) on XDA Developers.\nThis thread follows the same pattern for all releases.\n\nWhen writing a response to the XDA thread we follow another pattern of release notes. These examples\ncan be found below:\n\n1. [2.2.2](https://forum.xda-developers.com/showpost.php?p=70687935&postcount=4635)\n2. [2.2.1](http://forum.xda-developers.com/showpost.php?p=69188139&postcount=4478)\n3. [2.0.0](http://forum.xda-developers.com/showpost.php?p=60255972&postcount=3063)\n\n### Apktool Website\n\nThe Apktool project website has a few locations to update:\n\n1. The homepage intro\n2. The download link in header\n3. Migrating `unreleased.mx` to a new blog post.\n\nThe easiest way to describe this is to just link to a [previous release](https://github.com/iBotPeaches/Apktool/pull/3146/files).\n\n### Update Milestones\n\nNow that we've released a version, we should hopefully have no more tickets in the release just published.\nIf there are, move those tickets to the next milestone.\n\nYou can head to [milestones](https://github.com/iBotPeaches/Apktool/milestones) to close the just\nreleased version and create another.\n\nI tend to create the next release (In this case `2.2.3`) with an ETA of 3 months in the future. This\nis just a guideline but helps me to release a new version every 3 months.\n\n### Social Spam\n\nThe final step is to send this release into the wild via some social posting. Head to the blog\nwhere the release post was and send that link to Twitter, Google and whatever else you use.\n\nRelax and watch the bug tracker.\n\n# Building aapt2 binaries.\n\nThe steps taken for building our modified aapt2 binaries for apktool.\n\n### Getting the modified `frameworks/base` repo.\nFirst step is using the [platform_frameworks_base](https://github.com/iBotPeaches/platform_frameworks_base) repo.\n\nWhile previously unorganized, the repo now follows the branch naming convention depending on the current Android version.\nSo `apktool_7.1` corresponds to the 7.1 Android release. This branch should work for all `android-7.1.x` tags for AOSP.\n\nWe didn't follow this naming convention until Android 7.1. So don't go looking for older versions. The current version\nis `apktool-9.0.0`, which corresponds to the Android 9.0 (Pie) release.\n\nThis repo has a variety of changes applied. These changes range from disabling optimizations to lessening the rules\nthat aapt regularly has. We do this because apktool's job is to not fix apks, but rather keep them as close to the\noriginal as they were.\n\n### First we need the AOSP source\n\nAs cheesy as it is, just follow this [downloading](https://source.android.com/source/downloading.html) link in order\nto get the source downloaded. This is no small download, expect to use 150-250GB.\n\nSome optimization techniques for a smaller clone:\n\n * `~/bin/repo init -u https://android.googlesource.com/platform/manifest -b android16-release --partial-clone` - Partial clone\n * `repo sync -c` - Only current branch\n\nAfter that, you need to build AOSP via this [documentation](https://source.android.com/source/building.html) guide. Now\nwe aren't building the entire AOSP package, the initial build is to just see if you are capable of building it.\n\nWe check out a certain tag or branch. Currently, we use\n\n * aapt2 - `android-16-release`\n\n### Including our modified `frameworks/base` package.\n\nThere is probably a more automated way to do this, but for now:\n\n1. `cd frameworks/base`\n2. `git remote add origin git@github.com:iBotPeaches/platform_frameworks_base.git`\n3. `git fetch origin -v`\n4. `git checkout origin/apktool-{x}`\n\n#### Mac Patch\n\nNormally you'll be building this on a recent macOS that isn't supported. You'll want to follow these steps:\n\n1. `vim build/soong/cc/config/darwin_host.go`\n2. Find `darwinSupportedSdkVersions` array.\n3. Add number that corresponds to output of: `find /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs -iname \"*.sdk\"`\n\n### Building the aapt2 binary.\n\nThe steps below are different per flavor and operating system.\n\n#### Linux / Windows\n1. `source build/envsetup.sh`\n1. `lunch aosp_cf_x86_64_only_phone-aosp_current-eng`\n1. `m aapt2`\n1. `strip out/host/linux-x86/bin/aapt2`\n1. `strip out/host/linux-x86/bin/aapt2_64`\n1. `strip out/host/windows-x86/bin/aapt2.exe`\n1. `strip out/host/windows-x86/bin/aapt2_64.exe`\n\n#### Mac\n1. `export ANDROID_JAVA_HOME=/Path/To/Jdk`\n1. `source build/envsetup.sh`\n1. `lunch aosp_cf_x86_64_only_phone-aosp_current-eng`\n1. `m aapt2`\n1. `strip out/host/darwin-x86/bin/aapt2_64`\n\n#### Confirming aapt/aapt2 builds are static\n\nThere are some issues with some dependencies (namely `libc++`) in which they are built in the shared state. This is\nalright in the scope and context of AOSP/Android Studio, but once you leave those two behind and start using aapt on\nits own, you encounter some issues. The key is to force `libc++` to be built statically which takes some tweaks with the\nAOSP build systems as that dependency isn't standard like `libz` and others.\n\nYou can test the finalized project using tools like `ldd` (unix) and `otool -L` (mac) for testing the binaries looking\nfor shared dependencies.\n\n# Gradle Tips n Tricks\n\n    ./gradlew build shadowJar proguard -x test\n\nThis skips the testing suite (which currently takes 2-4 minutes). Use this when making quick builds and save the testing\nsuite before pushing to GitHub.\n\n    ./gradlew test --debug-jvm\n\nThis enables debugging on the test suite. This starts the debugger on port 5005 which you can connect with IntelliJ.\n\n    ./gradlew :brut.apktool:apktool-lib:test ---tests \"*BuildAndDecodeTest\"\n\nThis runs the library project of Apktool, selecting a specific test to run. Comes in handy when writing a new test and\nonly wanting to run that one. The asterisk is used to the full path to the test can be ignored. You can additionally\nmatch this with the debugging parameter to debug a specific test. This command can be found below.\n\n    ./gradlew :brut.apktool:apktool-lib:test --tests \"*BuildAndDecodeTest\" --debug-jvm\n\n<|im_end|>"}

It can decode resources to nearly original form and rebuild them after making some modifications; it makes it possible to debug smali code step-by-step. It also makes working with apps easier thanks to project-like file structure and automation of some repetitive tasks such as building apk, etc.\n\nApktool is **NOT** intended for piracy and other non-legal uses. It could be used for localizing and adding features, adding support for custom platforms, and other GOOD purposes. Just try to be fair with the authors of an app, that you use and probably like.\n\n### Branches\n- `main` - In-development Apktool 3.x branch\n- `2.x` - Maintenance branch for Apktool 2.x releases\n\n#### Support\n- [Project Page](https://apktool.org)\n- [#apktool on libera.chat](https://web.libera.chat)\n\n#### Security Vulnerabilities\n\nIf you discover a security vulnerability within Apktool, please send an e-mail to Connor Tumbleson at connor.tumbleson(at)gmail.com.

{"text": "<|im_start|>user\nYou are a Singularity-Level AI. Analyze this file from the 'APKTOOL' repository. Explain the technical logic, security implications (offensive/defensive), or financial algorithm involved.\nFile: ROADMAP.md\n<|im_end|>\n<|im_start|>assistant\nREPO: APKTOOL\nCODE:\n## Automatic Remapping of ResourceId\nWe currently prevent resourceIds from changing, by utilizing the `public.xml` file which makes the resources public, but\nthen prevents them to be used in some locations (`android:scheme`). The correct fix would be to record the resourceIds\nand use dexlib2 (no regular expressions) to rewrite them to the new resourceId after the `resources.arsc` is built.\n\nThis would be a lookup table of old->new resourceIds leveraging the API of dexlib2 to do the replacement. Doing this\nproperly would nullify the need to do [#191](https://github.com/iBotPeaches/Apktool/issues/191)\n\nSuggestions: [#244](https://github.com/iBotPeaches/Apktool/issues/244)\nDiscussions: [#2062](https://github.com/iBotPeaches/Apktool/issues/2062)\n\n## Implicit Qualifiers Cleanup\nCurrently we have a mismatch between reading the folders and reading the qualifiers which leads to a mismatch between\nimplicit qualifiers like version (-v4, v13, etc).\n\nThis was first spotted in bug [#1272](https://github.com/iBotPeaches/Apktool/issues/1272).\n\nThis was attempted to be fixed in [!1758](https://github.com/iBotPeaches/Apktool/pull/1758/files), but had to be\nreverted due to [this](https://github.com/iBotPeaches/Apktool/issues/1272#issuecomment-379345005).\n\nSuggestions: [#2237](https://github.com/iBotPeaches/Apktool/issues/2237)\n\n## Qualifier Plugin System\nFor some OEMs, past and present. They re-use qualifiers that AOSP ends up using. This with CTS is becoming very\nrare and pretty much a problem of the past, but now custom modifications and more \"off the cuff\" OEMs are doing\nit.\n\nApktool can't do anything because it stays true to AOSP. It would need a plugin system that controls how to\nread the qualifiers. Or even an override file.\n\nSuggestions: [#1420](https://github.com/iBotPeaches/Apktool/issues/1420), [#2474](https://github.com/iBotPeaches/Apktool/issues/2474)\n\n## Non-reference Resources\nSome applications may shove resources into the /res folder, but have no references to them. Apktool follows\nthe resource table, so these files are effectively abandoned.\n\nCrawling the filesystem for non-checked files would be slow especially having to cross check with already\nparsed files.\n\nSuggestions: [#1366](https://github.com/iBotPeaches/Apktool/issues/1366)\n\n## Android Support\nFolks have requested running Apktool on device itself. This has been a challenge due to the arch requirements\nthat would be placed on the aapt2/aapt binaries.\n\nSuggestions: [#2811](https://github.com/iBotPeaches/Apktool/issues/2811)\n\n## Split APK Support\nApplications are further getting split on qualifiers. Apktool has been built on the assumption of one apk.\n\nSuggestions: [#2283](https://github.com/iBotPeaches/Apktool/issues/2283), [#2218](https://github.com/iBotPeaches/Apktool/issues/2218), [#2880](https://github.com/iBotPeaches/Apktool/issues/2880)\n\n## Version relevant framework files\nApplications are built against a specific framework version. Apktool ships with the latest framework file at that\ntime of release. So an application built with API 33 may be recompiled with API 36 which leads to issues.\n\nApktool packing 15+ older framework files would bloat the distribution. A better solution would be to have a\ncentral repository of framework files that Apktool can download on demand, but that would require hosting\nand maintenance.\n\nSuggestions: [#3946](https://github.com/iBotPeaches/Apktool/issues/3946)\n\n<|im_end|>"}
