i tried many,
for instance todomvc sample gives me blank white screen

[drkemp]

I just verified that the todomvc at

https://github.com/GoogleChrome/chrome-app-samples.git

works on Android 4.4.2 on a Nexus 7.
I am using the latest cca installed via npm

Can you verify that you have the latest tools, and where you obtained the
sample app from?

The mobile supported chrome app samples are listed in a table at the bottom of the README.md: https://github.com/GoogleChrome/chrome-app-samples#mobile-support

If any of those apps are not working for you, that is not expected and we would be pleased for you to report the specific samples. Please also let us know more about your environment.

More generally -- whenever you see a blank white screen when running a chrome app on mobile via the cca tool, it is a sign of startup issues (and typically javascript syntax errors). It may be a bug in our environment startup code, since we do a bit of magic to simulate the chrome app runtime. More often it is because the application itself is relying on desktop chrome specific features that do not exist inside the mobile WebView.

The best way to find & resolve these issues is by attaching a remote web inspector, then restarting the app (while still having the inspector attached), to catch these startup issues in the console.

Here is a quick guide to do that:

1. Launch the cordova based mobile port of your Chrome App on Android / iOS using the cca tool
2. Attach a remote web inspector to the Android / iOS WebView by following one of these guides:
   1. Android: https://developers.google.com/chrome-developer-tools/docs/remote-debugging?hl=de
   2. iOS: http://phonegap-tips.com/articles/debugging-ios-phonegap-apps-with-safaris-web-inspector.html
3. If your app was stuck at a blank white screen at startup, and the remote inspector console shows no useful error messages, restart the app by manually typing chrome.runtime.reload() into the console.
4. Hopefully you will now see insightful error messages in the logs to help track down the startup issue.
5. Please, report back to us if the error was our fault!

Best of Luck.

@MrYogi I think that @drkemp has identified the root problem here -- you are trying the wrong samples! This is our fault, we should have made that repository less discoverable and offered warnings in the README. Sorry about that!

The correct place to look for samples is: https://github.com/GoogleChrome/chrome-app-samples.git

And again, you can find the list of valid working mobile samples at the bottom: https://github.com/GoogleChrome/chrome-app-samples#mobile-support

@MrYogi still interested to learn why you were seeing a white screen, but closing this as a not being an issue as currently described.
