I'm a new chrome extension developer, and I was going through the Chrome tutorial on making a "Hello World" extension, here's my code:
{ "name": "My First Extension", "version": "1.0", "manifest_version": 2, "description": "The first extension that I made.", "browser_action": { "default_icon": "icon.png" }, "permissions": [ "http://api.flickr.com/" ] }
When I went to load the unpacked extension it said the manifest file was missing or unreadable. Yes I have the image in a folder with it and it is correctly named manifest.json
In the task manager, locate the extension and tap End Process. This will disable the extension from the browser. Now, go to More Tools > Extensions and give the extension a fresh start by tapping on Reload. Even after the fixes above, if the extension doesn't load correctly, uninstall it and reinstall it.
The first thing to test is clearing the cache of your browser and restarting your browser, this will normally fix the issue.
The web app manifest is a JSON file that tells the browser about your Progressive Web App and how it should behave when installed on the user's desktop or mobile device.
Something that commonly happens is that the manifest file isn't named properly. Double check the name (and extension) and be sure that it doesn't end with .txt (for example).
In order to determine this, make sure you aren't hiding file extensions:
Also, note that the naming of the manifest file is, in fact, case sensitive, i.e. manifest.json != MANIFEST.JSON.
