The occurrence referenced by the search query signals a failure in establishing a secure connection between an Android device and a server. This arises when the device does not trust the Certificate Authority (CA) that issued the server’s security certificate. A common scenario is encountering a self-signed certificate, a certificate issued by an internal CA that is not recognized by default by Android’s trusted root certificate store. This prevents the secure exchange of data, as the device cannot verify the server’s identity.
This issue is significant because it directly impacts user security and privacy. Without proper certificate validation, data transmitted between the device and the server becomes vulnerable to interception and manipulation. Historically, such errors were more prevalent with custom or internal applications using less common certificate authorities. Resolving this issue is crucial for maintaining data integrity, building user trust in the application, and complying with security best practices.
