Есть один пример по этому поводу, правда сам делать не пробовал:

private String   mediaTypes[];
private final    String GIF_MIME_TYPE = "image/gif";
private boolean  gifSupported;    

// Get the media types to check for support of GIF file display
        mediaTypes = Manager.getSupportedContentTypes(null);
        int count = mediaTypes.length;

// Check list for GIF MIME type; set support flag if present
        gifSupported = false;
        for (int i = 0; i < count; i++) {
            if (mediaTypes[i] == GIF_MIME_TYPE)
                gifSupported = true;
        } // end for
