Tutorial Rebranding smarters apk
Offline
Renaming a package in a hard-coded APK can indeed be more challenging than modifying a regular Android project.
Here's an alternative approach that involves using the APKTool to manually decompile, modify, and recompile the APK.
Before proceeding, make sure you have Java JDK and APKTool installed on your system.
apktool d /path/to/your-apk-file.apk
This will decompile the APK, and you'll see a new directory with the same name as your APK file (without the .apk extension) containing the decompiled resources and code.
If you encounter issues during the smali modification or APK recompilation, you may need to troubleshoot and debug the code to ensure everything works as expected.

Before proceeding, make sure you have Java JDK and APKTool installed on your system.
- Decompile the APK using APKTool:
Open a command prompt (or terminal) and navigate to the directory where APKTool is installed. Then run the following command:
bash or windows shell , (windows shell will need you to set environmental values )
apktool d /path/to/your-apk-file.apk
This will decompile the APK, and you'll see a new directory with the same name as your APK file (without the .apk extension) containing the decompiled resources and code.
- Change the Package Name:
Navigate into the decompiled directory, and you should find a folder named smali or smali_classes2 (depending on the APK version). Inside this folder, you'll see the directory structure reflecting the original package name.
Use a text editor or IDE that supports smali code (which is like assembly language for Android) to change the package name. Find and replace all occurrences of the old package name with the new one. Be careful during this step, as smali code is low-level and can be easy to break if not modified correctly. - Change the Manifest:
Open the AndroidManifest.xml file in the decompiled directory. Change the package attribute in the <manifest> tag to the new package name. - Recompile the APK using APKTool:
After making the necessary changes, it's time to recompile the APK. Run the following command from the command prompt:
apktool b /path/to/decompiled-directory
This will recompile the modified code and resources back into a new APK. - Sign the APK:
Once the recompilation is successful, you'll find the new APK in the dist folder inside the decompiled directory. Before installing the APK on a device, you'll need to sign it with your keystore.

You can use also the Android Studio's Build > Generate Signed Bundle/APK option or the command-line tools like jarsigner to sign the APK.
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore your-keystore.keystore /path/to/new-apk-file.apk alias_name
- Test the APK:
After signing the APK, you should be able to install and test the renamed app on a device or emulator.
If you encounter issues during the smali modification or APK recompilation, you may need to troubleshoot and debug the code to ensure everything works as expected.
