Some time ago, there were still Chrome-packaged legacy apps which could make options-pages. I want to use the option-page in my Chrome app, but when I try to use it, the extension page shows:
''options_page' is only allowed for extensions, hosted apps, and legacy packaged apps, but this is a packaged app'.
How can I use an options-page or something of the kind to store and read settings for my app?
As the message above, you need to create an "option page" by yourself for the Chrome Apps. Also, you can use following features to store each value for the "option page":
That is, you should implement the feature for providing the "option page" by yourself, including a page creation, each event handling and storing each setting value.
