Error codes that may be returned from[MediaDrm.MediaDrmStateException.getErrorCode()](https://developer.android.com/reference/android/media/MediaDrm.MediaDrmStateException#getErrorCode())and[MediaCodec.CryptoException.getErrorCode()](https://developer.android.com/reference/android/media/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](https://developer.android.com/reference/android/media/MediaDrm#closeSession(byte[]))the session,[open](https://developer.android.com/reference/android/media/MediaDrm#openSession())a new session, and retry the operation
3. [close](https://developer.android.com/reference/android/media/MediaDrm#close())the[MediaDrm](https://developer.android.com/reference/android/media/MediaDrm)instance and any other related components such as the[codec](https://developer.android.com/reference/android/media/MediaCodec)and retry playback, or
4. try using a different configuration of the[MediaDrm](https://developer.android.com/reference/android/media/MediaDrm)plugin, such as a different[security level](https://developer.android.com/reference/android/media/MediaDrm#openSession(int)).
If the problem still persists after all the aforementioned steps, please report the failure to the[MediaDrm](https://developer.android.com/reference/android/media/MediaDrm)plugin vendor along with the[log messages](https://developer.android.com/reference/android/media/MediaDrm.LogMessage)returned by[MediaDrm.getLogMessages()](https://developer.android.com/reference/android/media/MediaDrm#getLogMessages()), and a bugreport if possible.
