Not getting correct extension file

[Kita2345]

Downloaded not in .json but in .bin extension file. Tried it on android 9 and indeed the correct file format is not displayed. returned like this downloadfile.bin Link https://android.googlesource.com/?format=JSON

Thanks for reporting this issue, I'll fix it in future versions (if I figure out how to do so). Before this happens, you can just rename the download file name manually.

now the extension can be correctly got.
