I made a chrome web store application and i lost the manifest.json file of the last version. Is there any way to get this file from the Developer Dashboard?
Solution
From the Developer Dashboard, click More Info for the app.
In the popup there is a link labeled Download: main.crx
Click the link to download your app's crx file.
Open the crx file in any zip file manager. It will include the manifest.json for the app.
