404 on network_service.mojom.dart, url_loader.mojom.dart and service_registry.mojom.dart #27
Description
When I try to run a Hello World Sky app on Android, I only get a black screen. Looking at logs, I see it can't find bunch of files:
27.0.0.1 - - [05/Jul/2015 08:33:41] code 404, message File not found
127.0.0.1 - - [05/Jul/2015 08:33:41] "GET /packages/mojom/mojo/network_service.mojom.dart HTTP/1.1" 404 -

What I am doing is just creating a simple main.dart in a folder with a pubspec.yaml that looks like:
name: your_app_name
dependencies:
sky: any
and doing a pub get and ./packages/sky/sky_tool start
pub get seems to be getting the latests versions(0.13)
Resolving dependencies... (1.2s)
+ args 0.13.2
+ mojo 0.0.13
+ mojom 0.0.13
+ path 1.3.5
+ sky 0.0.13
+ vector_math 1.4.3
I have also tried uninstalling SkyDemo and running with ./packages/sky/sky_tool start --install, but same issue.

It sounds like pub run sky:init wasn't run (which calls pub run momom:generate). ./packages/sky/sky_tool should do that for you however.
I can attempt to reproduce when I'm in the office. I suspect I failed to publish the latest Sky package correctly. @johnmccutchan

On a clean sky_test project:

After attaching a device I see what's going on.

This should be fixed in https://codereview.chromium.org/1224623007/

@aghassemi Until the next revision of the Sky SDK a work around is:

Thanks @johnmccutchan Workaround fixed the 404s.
I still get a black screen on the Hello World example but that should not be related to this issue. I get the black screen on a fresh install of the SkyDemo from the App store too. (Nexus 7, Android 5.1.1), any thoughts on where to look for the root cause?

It probably is black text on a black background. When we moved from the old world (.sky) to the new world (.dart) we changed the default background color from white to black to avoid the flash-of-white problem that the Web had for years during the load of pages.
I suspect we need to update hello_world to set a text color:

I think that we changed the default text color to white last week. In the current world, though, hello_world draws its text under the status bar, which can make it hard to notice. Do you see that text when you run hello_world on your device?
aghassemi commentedon Jul 7, 2015
@eseidel @iansf Thanks for the hints. It was both a black-on-black and under-the-statusbar issue. Putting it in a container with light background, I can see the text just fine now. ( I was creating my own hello world based on the code in README rather than trying the examples/hello_world so the text is still black )
Use the NDK at API level 16 for backward compatibility with Jellybean (…
