The decode option on Apktool can be invoked either from d or decode. In order to run a rebuilt application, you must resign the application. Android documentation can help with this.
As you probably know, Android apps utilize code and resources that are found on the Android OS itself. These are known as framework resources and Apktool relies on these to properly decode and build apks. Framework resources are stored in a file called framework 1.apk, which is located in the /system/framework/ directory on your device. Apktool needs this file to decode any app that depends on it.
How to install apktool on Windows
To install apktool on your Windows computer, you need to follow these steps:
Download the required files. You need to download two files: a Windows wrapper script (apktool.bat) and a jar file (apktool.jar). You can find the latest versions of these files on the official website or on the GitHub page. Make sure you rename the downloaded jar file to apktool.jar.
Move them to the Windows directory. You need to move both files (apktool.jar and apktool.bat ) to the Windows directory (Usually C:\Windows). This will allow you to access apktool from anywhere on your computer.
Test the installation. To test if apktool is installed correctly, open a command prompt (cmd.exe) and type apktool. You should see a list of available commands and options. If you see an error message, make sure you have followed the previous steps correctly and that you have Java installed on your computer.
Congratulations! You have successfully installed apktool on your Windows computer. Now you can use it to decode and rebuild apk files.
How to use apktool to decode and rebuild apk files
To use apktool to decode and rebuild apk files, you need to follow these steps:
Decode an apk file using apktool d command. To decode an apk file, you need to use the d or decode option followed by the name of the apk file. For example, if you want to decode an app called example.apk, you need to type apktool d example.apk. This will create a folder called example in the same directory as the apk file, containing the decoded resources and smali code.
Make some modifications to the decoded resources. Once you have decoded the apk file, you can make some changes to the resources and smali code according to your needs. For example, you can edit the strings, images, layouts, colors, etc. You can also add or remove features, fix bugs, or optimize performance. Be careful not to break the functionality or compatibility of the app.
Rebuild the apk file using apktool b command. To rebuild the apk file, you need to use the b or build option followed by the name of the folder containing the decoded resources. For example, if you want to rebuild the app called example, you need to type apktool b example. This will create a new apk file called example/dist/example.apk, containing the modified resources and smali code.
You have successfully used apktool to decode and rebuild an apk file. Now you can test it on your device or emulator. Remember that you need to resign the app before installing it.
How to solve some common problems with apktool
Sometimes, you might encounter some errors or problems while using apktool. Here are some of the most common ones and how to solve them:
Framework 1.apk not found error
This error occurs when you try to decode an app that depends on framework resources but you don't have framework 1.apk installed on your computer. To solve this problem, you need to copy framework 1.apk from your device or emulator to your computer and install it using apktool. To do this, follow these steps:
Copy framework 1.apk from your device or emulator to your computer. You can use adb (Android Debug Bridge) or any other method to copy framework 1.apk from your device or emulator to your computer. The file is located in the /system/framework/ directory on your device or emulator.
Install framework 1.apk using apktool. To install framework 1.apk using apktool, you need to use the if or install-framework option followed by the name of the file. For example, if you have copied framework 1.apk to your Windows directory, you need to type apktool if framework 1.apk. This will install framework 1.apk as framework-res.apk in your user home directory under .local/share/apktool/framework/1.apk.
Rerun the decode command. After installing framework 1.apk using apktool, you can rerun the decode command for the app that depends on it. For example, if you want to decode an app called example.apk, you need to type apktool d example.apk. This time, it should work without any errors.
You have successfully solved the framework 1.apk not found error. Now you can modify and rebuild the app as usual.
Dex overflow error
This error occurs when you try to rebuild an app that has too many classes or methods in the dex file. Dex files are executable files that contain compiled code and data for Android apps. There is a limit of 65536 classes or methods per dex file, which is known as the 64K reference limit. If you exceed this limit, you will get a dex overflow error while rebuilding the app.
To solve this problem, you need to enable multidex, which allows you to split your app into multiple dex files. To do this, follow these steps:
Edit the apktool.yml file. The apktool.yml file is a configuration file that contains information about the app, such as version, permissions, features, etc. You can find it in the folder that contains the decoded resources of the app. To enable multidex, you need to add a line that says useMultidex: true under the doNotCompress: section. For example, your apktool.yml file might look like this:
version: 2.0 apkFileName: example.apk isFrameworkApk: false usesFramework: ids: - 1 sdkInfo: minSdkVersion: '21' targetSdkVersion: '29' packageInfo: forced-package-id: '127' versionInfo: versionCode: '1' versionName: '1.0' sharedLibrary: false doNotCompress: - arsc - assets/secondary-dex-1 - assets/secondary-dex-2 - assets/secondary-dex-3 useMultidex: true
Rerun the build command. After editing the apktool.yml file, you can rerun the build command for the app. For example, if you want to rebuild the app called example, you need to type apktool b example. This time, it should work without any errors and create multiple dex files in the output apk.
You have successfully solved the dex overflow error. Now you can test and install the app as usual.
Signature verification error
This error occurs when you try to install an app that has been modified by apktool but has not been resigned properly. Android requires that all apps are signed with a digital certificate that identifies the developer and ensures the integrity of the app. If you modify an app using apktool, you need to resign it with a new certificate before installing it.
To solve this problem, you need to use a tool that can sign apk files, such as apksigner, jarsigner, or signapk. To do this, follow these steps:
Create a new certificate and key pair. You need to create a new certificate and key pair that will be used to sign the modified app. You can use any tool that can generate these files, such as keytool, which is included in Java Development Kit (JDK). For example, to create a new certificate and key pair called mykey.keystore, you need to type keytool -genkey -v -keystore mykey.keystore -alias mykey -keyalg RSA -keysize 2048 -validity 10000. You will be asked to enter some information and a password for the keystore.
Sign the modified app using apksigner. Apksigner is a tool that can sign apk files using certificates and keys. It is included in Android SDK Build Tools. For example, to sign a modified app called example.apk using apksigner and the certificate and key pair called mykey.keystore, you need to type apksigner sign --ks mykey.keystore --ks-key-alias mykey example.apk. You will be asked to enter the password for the keystore.
Install the signed app on your device or emulator. After signing the modified app using apksigner, you can install it on your device or emulator using adb or any other method. For example, to install an app called example.apk using adb, you need to type adb install example.apk.
You have successfully solved the signature verification error. Now you can enjoy your modified app.
