# MediaDrm.ErrorCodes

`public static final class MediaDrm.ErrorCodes`
`extends Object` ``

java.lang.Object
↳ | android.media.MediaDrm.ErrorCodes

Error codes that may be returned from `MediaDrm.MediaDrmStateException.getErrorCode()` and `MediaCodec.CryptoException.getErrorCode()`

The description of each error code includes steps that may be taken to resolve the error condition. For some errors however, a recovery action cannot be predetermined. The description of those codes refers to a general strategy for handling the error condition programmatically, which is to try the following in listed order until successful:

1. retry the operation
2. if the operation is related to a session, `close` the session, `open` a new session, and retry the operation
3. `close` the `MediaDrm` instance and any other related components such as the `codec` and retry playback, or
4. try using a different configuration of the `MediaDrm` plugin, such as a different `security level`.

If the problem still persists after all the aforementioned steps, please report the failure to the `MediaDrm` plugin vendor along with the `log messages` returned by `MediaDrm.getLogMessages()`, and a bugreport if possible.
