      * <p>Configuring a session with an empty or null list will close the current session, if

      *
+     * <p>While any of the sizes from {@link StreamConfigurationMap#getOutputSizes} can be used when
+     * a single output stream is configured, a given camera device may not be able to support all
+     * combination of sizes, formats, and targets when multiple outputs are configured at once.  The
+     * tables below list the maximum guaranteed resolutions for combinations of streams and targets,
+     * given the capabilities of the camera device.</p>
+     *
+     * <p>If an application tries to create a session using a set of targets that exceed the limits
+     * described in the below tables, one of three possibilities may occur. First, the session may
+     * be successfully created and work normally. Second, the session may be successfully created,
+     * but the camera device won't meet the frame rate guarantees as described in
+     * {@link StreamConfigurationMap#getOutputMinFrameDuration}. Or third, if the output set
+     * cannot be used at all, session creation will fail entirely, with
+     * {@link CameraCaptureSession.StateListener#onConfigureFailed} being invoked.</p>
+     *
+     * <p>For the type column, {@code PRIV} refers to any target whose available sizes are found
+     * using {@link StreamConfigurationMap#getOutputSizes(Class)} with no direct application-visible
+     * format, {@code YUV} refers to a target Surface using the
+     * {@link android.graphics.ImageFormat#YUV_420_888} format, {@code JPEG} refers to the
+     * {@link android.graphics.ImageFormat#JPEG} format, and {@code RAW} refers to the
+     * {@link android.graphics.ImageFormat#RAW_SENSOR} format.</p>
+     *
+     * <p>For the maximum size column, {@code PREVIEW} refers to the best size match to the
+     * device's screen resolution, or to 1080p ({@code 1920x1080}), whichever is
+     * smaller. {@code RECORD} refers to the camera device's maximum supported recording resolution,
+     * as determined by {@link android.media.CamcorderProfile}. And {@code MAXIMUM} refers to the
+     * camera device's maximum output resolution for that format or target from
+     * {@link StreamConfigurationMap#getOutputSizes}.</p>
+     *
+     * <p>To use these tables, determine the number and the formats/targets of outputs needed, and
+     * find the row(s) of the table with those targets. The sizes indicate the maximum set of sizes
+     * that can be used; it is guaranteed that for those targets, the listed sizes and anything
+     * smaller from the list given by {@link StreamConfigurationMap#getOutputSizes} can be
+     * successfully used to create a session.  For example, if a row indicates that a 8 megapixel
+     * (MP) YUV_420_888 output can be used together with a 2 MP {@code PRIV} output, then a session
+     * can be created with targets {@code [8 MP YUV, 2 MP PRIV]} or targets {@code [2 MP YUV, 2 MP
+     * PRIV]}; but a session with targets {@code [8 MP YUV, 4 MP PRIV]}, targets {@code [4 MP YUV, 4
+     * MP PRIV]}, or targets {@code [8 MP PRIV, 2 MP YUV]} would not be guaranteed to work, unless
