*** ** * ** ***

An exception indicating one of a variety of problems encountered when validating a certification path.

A `CertPathValidatorException` provides support for wrapping exceptions. The `https://developer.android.com/reference/java/lang/Throwable#getCause()` method returns the throwable, if any, that caused this exception to be thrown.

A `CertPathValidatorException` may also include the certification path that was being validated when the exception was thrown, the index of the certificate in the certification path that caused the exception to be thrown, and the reason that caused the failure. Use the `https://developer.android.com/reference/java/security/cert/CertPathValidatorException#getCertPath()`, `https://developer.android.com/reference/java/security/cert/CertPathValidatorException#getIndex()`, and `https://developer.android.com/reference/java/security/cert/CertPathValidatorException#getReason()` methods to retrieve this information.

**Concurrent Access**

Unless otherwise specified, the methods defined in this class are not thread-safe. Multiple threads that need to access a single object concurrently should synchronize amongst themselves and provide the necessary locking. Multiple threads each manipulating separate objects need not synchronize.

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public CertPathValidatorException (Throwable cause)
```

Creates a `CertPathValidatorException` that wraps the specified throwable. This allows any exception to be converted into a `CertPathValidatorException`, while retaining information about the wrapped exception, which may be useful for debugging. The detail message is set to (`cause==null ? null : cause.toString()`) (which typically contains the class and detail message of cause).

### getIndex

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getIndex ()
