Recently, after doing some Google mandated updates of MusicSync , my music player Android application, I received the following error in Android Studio during the build process.

AAPT2 aapt2-8.8.0-12006047-osx Daemon #1: Daemon startup failed

I tried to search for the error on Google, and got zero results .

A Google search result page includes a result for a query about an 'AAPT2 Daemon startup failed' error, explaining potential causes related to software configuration.

While Perplexity gave me 6 possible causes of this.

Possible Causes and Solutions

1. Gradle Version Incompatibility:
   Ensure that your Gradle version is compatible with your Android Studio version.
   You may need to update or downgrade your Gradle version 2.
2. System User Permissions: If you're using a CI/CD
   system like Jenkins, make sure the build is not running under the SYSTEM user.
   Running the build as a specific admin user can resolve this issue.
3. Corrupted Gradle Cache: Try clearing the Gradle cache by deleting the ~/.gradle/caches
   folder in your user home directory.
4. Insufficient System Resources:
   Ensure your system has enough memory and processing power available for the build process.
5. Antivirus Interference:
   Temporarily disable your antivirus software to check if it's interfering with
   the build process.
6. Outdated Android SDK Tools: Update your Android SDK
   tools to the latest version through the SDK Manager.

The third suggestion of the Gradle cache being corrupted looked promising answer. Especially because I was doing a Gradle version update. So, doing a clean build after deleting the Gradle cache ~/.gradle/caches resolved the issue.

I am definitely perplexed though.
Android comes from Google.
The error message came during Android build process.
The error message came from tools provided by Google.
It showed up in Android Studio, which is also from Google.
Yet, Google Search couldn’t find a single cause for the error message.

And this is not the only anecdotal evidence of Google Search failing to find relevant results. Something seems to be happening at Google which is making it less reliable.

Or, fairly frequently, I see nonsensical search results that are completely unrelated to the page contents.

There is a deterioration in the quality of search results. And these days, I frequently find myself using Perplexity as my primary search engine.
