APK2AAB With DistractionOptimized Changes

This repository has a script in it that will convert a .apk file and turn it into a .aab file with a couple of modifications to make driving while using the app possible. Unlike the other apk2aab repositories, this repository actually has source code to look trough to ensure it's not a virus.

Installation

Before running the script you will need a couple of tools:

Tool Name	Description	Download Link	Version
apktool.jar	Used to decompile the apk	Official website	Latest version
aapt2.exe	Used to compile resources and link proto buff	Dexpatcher apktool-aapt2 Repo	Match version as above
bundletool.jar	Used to bundle everything back to aab file	Google bundletool Repo	Latest version
android.jar	Android jar of correct SDK version	Sable Android Releases Repo	Play around with this

NOTE: To get a aap2.exe file, you should extract the jar, go to windows and copy out the aapt2.exe file.

Execution

To run this script. You should run following command: .\apk2aab.ps1 -ApkPath "app.apk" -ApktoolJarPath "apktool.jar" -Aapt2ExePath "aapt2.exe" -AndroidJarPath "android-33.jar" -BundletoolJarPath "bundletool.jar" -KeystorePath "keystore.jks" -KeyAlias "alias"

Description

This script will:

• Decompile the apk
• Modify the Android Manifest to make using the app while driving possible
• Compile the resources
• Link resources with manifest
• Create structure for .aab file
• Convert to .aab file
• Sign .aab

Detail steps

Make sure the .apk file is in a empty directory, this will make the cleanup easier.

Decompile APK

java -jar apktool_2.11.1.jar d app.apk -o decompile_apk -f -s

Edit Android Manifest

Go into decompiled folder, and edit AndroidManifest.xml: • Delete 'com.android.vending.derived.apk.id' meta data • Add 2 permissions: • Add distractionOptimized to all activities wanted • Update package name to match parameter

Compile resources

aapt2.exe compile --dir decompile_apk\res -o res.zip'

Link resources

aapt2.exe link --proto-format -o base.zip -I ..\android-33.jar --manifest .\decompile_apk\AndroidManifest.xml --min-sdk-version 31 --target-sdk-version {LATEST SDK VERSION} --version-code 1 --version-name 1.0 -R res.zip --auto-add-overlay

The script will check if we get following error:

• For resource x is private => Go to the xml and make all @android: occurences equal @\*android => Return to previous step

If you get any other erros from resource not found, make sure to play around with the android.jar versions. This only worked for me with android-33.

Create new bundle zip

Unzip base.zip Copy AndroidManifest.xml to manifest/AndroidManifest.xml Copy assets and lib folder from original decompile Copy contents of unknown to root/_ Copy all .dex files to dex/_ Final base directory structure should resemble:

├── assets/
├── dex/
├── lib/
├── manifest/
│ └── AndroidManifest.xml
├── res/
├── root/
│ └── (unknown files, kotlin folder)
└── resources.pb

Zip contents

jar cMf base.zip manifest dex res root lib assets resources.pb

Bundle to aab

java -jar bundletool.jar build-bundle --modules=base.zip --output=unsigned.aab

Sign the bundle

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore <path_to_your_keystore>.jks -storepass <keystore_password> -keypass <key_password> <your_app_name>.aab <your_key_alias>
