Merge "Update WebView.loadData docs for Q targetSdk quirk."

     * <p>

     * The {@code encoding} parameter specifies whether the data is base64 or URL

     * encoded. If the data is base64 encoded, the value of the encoding

     * parameter must be 'base64'. HTML can be encoded with {@link

     * parameter must be {@code "base64"}. HTML can be encoded with {@link

     * android.util.Base64#encodeToString(byte[],int)} like so:

     * <pre>

     * String unencodedHtml =

     * String encodedHtml = Base64.encodeToString(unencodedHtml.getBytes(), Base64.NO_PADDING);

     * webView.loadData(encodedHtml, "text/html", "base64");

     * </pre>

     * <p>

     * <p class="note">

     * For all other values of {@code encoding} (including {@code null}) it is assumed that the

     * data uses ASCII encoding for octets inside the range of safe URL characters and use the

     * standard %xx hex encoding of URLs for octets outside that range. See <a

     * href="https://tools.ietf.org/html/rfc3986#section-2.2">RFC 3986</a> for more information.

     * Applications targeting {@link android.os.Build.VERSION_CODES#Q} or later must either use

     * base64 or encode any {@code #} characters in the content as {@code %23}, otherwise they

     * will be treated as the end of the content and the remaining text used as a document

     * fragment identifier.

     * <p>

     * The {@code mimeType} parameter specifies the format of the data.

     * If WebView can't handle the specified MIME type, it will download the data.

     * <p>

     * If the base URL uses the data scheme, this method is equivalent to

     * calling {@link #loadData(String,String,String) loadData()} and the

     * historyUrl is ignored, and the data will be treated as part of a data: URL.

     * historyUrl is ignored, and the data will be treated as part of a data: URL,

     * including the requirement that the content be URL-encoded or base64 encoded.

     * If the base URL uses any other scheme, then the data will be loaded into

     * the WebView as a plain string (i.e. not part of a data URL) and any URL-encoded

     * entities in the string will not be decoded.
