How to get image file path from URI in Android Lollipop?

I want to create an image picker for Android Lollipop. I use Intent.ACTION_GET_CONTENTto select my image, but I cannot get the path to the selected image from the URI that returned the selection dialog.

I tried codes from these threads:

but they all return null. Can anyone help me?

and use:

private String uriToFilename(Uri uri) {
    String path = null;

    if (Build.VERSION.SDK_INT < 11) {
        path = RealPathUtil.getRealPathFromURI_BelowAPI11(mContext, uri);
    } else if (Build.VERSION.SDK_INT < 19) {
        path = RealPathUtil.getRealPathFromURI_API11to18(mContext, uri);
    } else {
        path = RealPathUtil.getRealPathFromURI_API19(mContext, uri);
    }

    return path;
}
