+     * @param characteristics
+     *     The characteristics of internal camera contains a list of keys so that

+     *           - Including too many output streams of a certain format.
+     *           - Unsupported rotation configuration
+     *           - Stream sizes/formats don't satisfy the
+     *             StreamConfigurationMode requirements
+     *             for non-NORMAL mode, or the requested operation_mode is not
+     *             supported by the HAL.
+     *           - Unsupported usage flag
+     *         The camera service cannot filter out all possible illegal stream
+     *         configurations, since some devices may support more simultaneous
+     *         streams or larger stream resolutions than the minimum required
+     *         for a given camera device hardware level. The HAL must return an
+     *         ILLEGAL_ARGUMENT for any unsupported stream set, and then be
+     *         ready to accept a future valid stream configuration in a later
+     *         configureInjectionStreams call.
