1. Create a keystore:
jarsigner -verbose -sigalg SHA256withRSA -digestalg SHA-256 -keystore your_keystore.jks modified_app.apk your_alias
APKTool M is a powerful tool for decompiling, modifying, and recompiling Android app packages. By following this tutorial, you should be able to successfully use APKTool M to modify and recompile an APK. However, please note that modifying APKs may infringe on copyright laws or violate the terms of service of the original app developers. Always ensure you have the necessary permissions and comply with applicable laws.
* `jarsigner` signs the APK. * `-verbose` enables verbose output. * `-sigalg SHA256withRSA` specifies the signature algorithm. * `-digestalg SHA-256` specifies the digest algorithm. * `-keystore your_keystore.jks` specifies the keystore file. * `modified_app.apk` is the APK file to sign. * `your_alias` is the alias.
**Step 4: Signing the APK (Optional)** -------------------------------------
* `b` stands for build. * `.` represents the current directory. * `-o modified_app.apk` specifies the output APK file.
If you want to install the recompiled APK on a device or distribute it, you'll need to sign it with a certificate.
