Unzip the apk
Put all tool files in one folder
Open your command prompt in current directory
Decompile the apk through apktool.jar
execute below command in command line
java -jar apktool_2.5.0.jar d test.apk -s -o decompile_apk -f
Compile the resource
Compile the resources using aapt2
aapt2.exe compile --dir decompile_apk\res -o res.zip
After that you will see a res.zip will generate in your current directory
Link the resources
execute below command in command line
aapt2.exe link --proto-format -o base.zip -I android.jar --manifest decompile_apk\AndroidManifest.xml --min-sdk-version $version --target-sdk-version $version --version-code $version --version-name $version -R res.zip --auto-add-overlay
$version should be replace with your apk version for example my apk have min-sdk is 7 , target-sdk is 30 , version-code is 1 , verison-name is 1.0 . So my command will be →
aapt2.exe link --proto-format -o base.zip -I android.jar --manifest decompile_apk\AndroidManifest.xml --min-sdk-version 7 --target-sdk-version 30 --version-code 1 --version-name 1.0 -R res.zip --auto-add-overlay
After that you will see a base.zip will generate in your current directory
Unzip the base.zip
Directory structure:
base/
/AndroidManifest.xml
/res
/resources.pb
Copy the files
Take base folder as your main folder for now !
Create a folder manifest name folder inside base folder and move your base/AndroidManifest.xml to manifest/AndroidManifest.xml
copy whole assets folder from decompile_apk/assets and paste to base/assets
copy lib folder from decompile_apk/lib and paste to base/lib
copy all files inside unknown folder from decompile_apk/unknown and paste to base/root

jar cMf base.zip manifest dex res root lib assets resources.pb
It will create base.zip in current directory now copy the base.zip and paste where you put all tool file (.jars , .exe)
Compile aab
Open your command prompt in /tools directory
execute below command in command line
java -jar bundletool.jar build-bundle --modules=base.zip --output=base.aab
base.aab file will generate in current folder
You need to sign the generated aab file with your keystore in order to publish the application in play store
