content://com.android.externalstorage.documents/document/primary%3A

选择文件 URI 又查不到真实路径了，特征如标题。

识别并替换

if (suri.startsWith("content://com.android.externalstorage.documents/document/primary%3A")) {
    filepath = suri.replace("content://com.android.externalstorage.documents/document/primary%3A", Environment.getExternalStorageDirectory().getPath() + File.separator);
}
