I’ve been stuck on the PLACES_API_KEY_INVALID error for days now, and I’ve gone through every related issue and solution I could find online—nothing seems to fix it. Here’s what I’ve already tried:

• I’ve double-checked that my credentials are properly configured in the Google Cloud Console
• The API key in my AndroidManifest.xml is definitely the correct one linked to my project, with no typos or copy-paste errors
• I’ve scoured developer forums, official docs, and troubleshooting guides, but none of the suggested fixes work for my case
• I tried switching to Google Play Services version 11.2 (which the docs mention introduces a new implementation approach for Places), but I can’t download this version. Right now, I’m using Google Play Places version 9.2.

Below is a screenshot of my Google Cloud Console interface:
