background
I'm learning how to build a chrome extension app, and I'm following the instructions in this tutorial (you can see my code here).
The instructions in the copy key to your manifest section states that it's important to keep their application id constant and in order to do that, they must copy the key in the installed manifest.json to the source manifest.
The instructions state that this manifest.json file must exist in the user data directory, in my case (mac):
~/Library/Application\ Support/Google/Chrome/Default/Extensions
a folder corresponding to my chrome extension app id should show up there
problem
I couldn't find my folder in that directory. By failing to include they key in the manifest file as they did in the chrome identity example then evey time I click on the sign in button, it simply opens a new tab and prompts the user to enter their email/password, but then the extension never gets the token.
what I have tried
I realized that there are many app id folders that exist on the said directory, but they are only for the apps I installed from google chrome webstore (ie google docs etc).. but not any of the apps I loaded by checking the developer mode checkbox then clicking on the Load unpacked extension.. button.
consider this (my app is documentivly, and the tutorial app is identity api sample):
If I go to
~/Library/Application Support/Google/Chrome
and search for the folder containing my app's id:
find . | grep cmfbnommmmeccnkbochkfakncgnebckn
I get

so none of the folders appear in the Default/Extensions directory as instructed by the tutorial.
If I search for the app id of google drive (lmjegmlicamnimmfhcmpkclmigmmcbeh), I find the folder in the Default/Extensions

What's interesting is that there is no manifest.json to be found anywhere in any of the directories of my installed app.. consider this:
~/Library/Application Support/Google/Chrome$ find . grep manifest.json | grep cmfbnommmmeccnkbochkfakncgnebckn
returns nothing!
ideas?
回答1:
While working on unpacked version you can skip the step for adding the key to your manifest file, but be sure to add the oAuth key to the manifest file and also use the extension key while creating Credentials for the oAuth.
You can test your extension without uploading it on a webstore.
