Android Q上手机连接电脑，电脑端打开SD卡，文件或文件夹不能重命名

问题现象：手机连接电脑–电脑端打卡SD卡–新建文件夹–重命名之后会弹出一个对话框提示错误，重新链接usb之后查看文件夹其实已经重命名成功

问题分析：

从log中看到 /mnt/media_rw/E0CE-13E7/asdfasas doesn’t appear under [/storage/E0CE-13E7] 两个路径不匹配导致无法出错，原因应该是在

frameworks/base/core/java/android/os/storage/VolumeInfo.java 中路径给改了
public File getInternalPathForUser(int userId) {
    if (path == null) {
        return null;
    } else if (type == TYPE_PUBLIC || type == TYPE_STUB) {
        // TODO: plumb through cleaner path from vold
        return new File(path.replace("/storage/", "/mnt/media_rw/"));   // 这里把路径改了
    } else {
        return getPathForUser(userId);
    }
}

修改方法如下，不确定是否会有其他问题:

packages/providers/MediaProvider/src/com/android/providers/media/MediaProvider.java
private static void assertFileColumnsSane(int match, Uri uri, ContentValues values)
        throws VolumeArgumentException {
    if (!values.containsKey(MediaColumns.DATA)) return;
    try {
        // Sanity check that the requested path actually lives on volume
        final String volumeName = resolveVolumeName(uri);
        final Collection<File> allowed = getVolumeScanPaths(volumeName);
-        final File actual = new File(values.getAsString(MediaColumns.DATA))
+        final File actual = new File(values.getAsString(MediaColumns.DATA).replaceAll("/mnt/media_rw/", "/storage/"))
                .getCanonicalFile();
        if (!FileUtils.contains(allowed, actual)) {
            throw new VolumeArgumentException(actual, allowed);
        }
    } catch (IOException e) {
        throw new IllegalArgumentException(e);
    }
}
