Understanding the Exception
The SSLHandshakeException is a common exception in Android applications that communicate over HTTPS. It indicates a failure in the SSL/TLS handshake process, which is responsible for establishing a secure connection between the client (your Android app) and the server. The CertPathValidatorException within this context usually points to a problem with the SSL certificate validation.
Causes of SSLHandshakeException with CertPathValidatorException
Several factors can lead to the SSLHandshakeException with CertPathValidatorException in Android. Some common causes include:
Expired or Invalid SSL Certificate: The server's SSL certificate might be expired or invalid, causing the validation process to fail.
Mismatched Hostname: The hostname in the SSL certificate doesn't match the hostname of the server to which the Android app is trying to connect.
Incomplete Certificate Chain: The certificate chain presented by the server is incomplete, and the device cannot verify the complete path to a trusted root certificate.
Addressing the Issue
To resolve the SSLHandshakeException, consider the following steps:
Check SSL Certificate Validity
Ensure that the SSL certificate on the server is valid and has not expired. If needed, update or renew the SSL certificate.
Verify Hostname
Confirm that the hostname in the SSL certificate matches the hostname of the server. Mismatched hostnames can trigger the SSLHandshakeException.
Complete Certificate Chain
Ensure that the server provides a complete certificate chain during the SSL handshake. All intermediate certificates up to the trusted root certificate should be included.
TrustManager Implementation
Implement a custom TrustManager to handle the SSL certificate validation. This allows you to customize the certificate validation process according to your requirements.
