+     * <p>Starting in {@link android.os.Build.VERSION_CODES#N}, this call initiates an asynchronous
+     * upload to the GPU on RenderThread, if the Bitmap is not already uploaded. With Hardware
+     * Acceleration, Bitmaps must be uploaded to the GPU in order to be rendered. This is done by
+     * default the first time a Bitmap is drawn, but the process can take several milliseconds,
+     * depending on the size of the Bitmap. Each time a Bitmap is modified and drawn again, it must
+     * be re-uploaded.</p>

+     * to be displayed. It is recommended to make any pre-draw modifications to the Bitmap before
+     * calling this method, so the cached, uploaded copy may be reused without re-uploading.</p>
