Android Question Google OAuth2 - Error 400: redirect_uri_mismatch

[JOTHA]

Hello Forum,

I used the Example Google OAuth2 from Erel, but I get this Error 400: redirect_uri_mismatch

I've seen that this problem is dicussed in the forum, but there is no solution on this case.
I want to have access to Google Sheets, so I tried first the example with "Contacts" from Erel.

Can anyone point me out to a solution?

Thanks in advance.

All that I can say is that you probably misconfigured something.

Hi Erel,

after you told me that I had obviously made a mistake, I went through everything again step by step and possibly found the mistake.

But when I wanted to test the code, the following message suddenly came up:
"The developer of this app is not recognized by Play Protect. Apps from unknown developers may not be safe."

I ignored the hint and clicked on "Install anyway".

Then came the message: "App was not installed."
I repeated the process several times, but the same message always came up.

How can I solve this problem?

Are you using B4A-Bridge or USB debug mode? If you are able to use USB debug mode then try it, as it will provide more information.

Also try to uninstall the existing app from the device, clean the project (Ctrl + P) and run again.
