What does this actually means: Warning: The signer's certificate is self-signed. POSIX file permission and/or symlink attributes detected. These attributes are ignored when signing and are not protected by the signature.

on after your local Android APK build for release version, basically it means, as learned from AI source to understand it real cause of the warning, so no need to worry much, you can continue reading the details for more understandings.

It indicates that the certificate used to sign the file is self-signed, meaning it was generated by the developer rather than being issued by a trusted certificate authority.

Additionally, the warning mentions POSIX file permission and/or symlink attributes. POSIX refers to the Portable Operating System Interface, which defines a standard set of APIs for compatibility between different Unix-like operating systems. The warning suggests that the file permissions and symbolic links present in the file are ignored during the signing process and are not protected by the digital signature.

This warning is informational and does not necessarily indicate an error or problem. Self-signed certificates are commonly used during development or testing stages, but for production or public distribution, it is recommended to use certificates issued by trusted certificate authorities.

If you are encountering this warning while signing an APK file, you can consider obtaining a certificate from a trusted certificate authority to replace the self-signed certificate. This will provide users with more confidence in the authenticity and integrity of the application. However, if you are using a self-signed certificate for personal or internal use, you can generally ignore this warning as long as you trust the source of the file and its contents.

It’s important to note that the warning regarding POSIX file permission and symlink attributes being ignored during signing does not have a significant impact on the functionality of the signed file. The signature primarily ensures the integrity of the file contents and detects any modifications made after signing.
