Hi,

I downloaded project and build it (as I'm using Ubuntu 14.04 Kernel 3.13 x86_64) and tried to create the hello world application. It seems to work fine in my computer (no error in the terminal) but when I open the app in my phone it just shows a black screen. Below the output from the commands:

Thanks for the report. We'll probably need to add more diagnostics to figure out what's going on...

is there any thing that I could help to solve the issue?

In http://flutter.io/getting-started/ mentioned that I could also use http://localhost:8181/ to get some debug information but the page generated seems broken, I got the following error from my js console:
webcomponents.min.js:13 Uncaught TypeError: Math.random is not a function(anonymous function) @ webcomponents.min.js:13(anonymous function) @ webcomponents.min.js:13

@luan-cestari, the web app there (Dart's Observatory) might need to be viewed in Chrome. cc'ing @johnmccutchan

@luan-cestari You could try putting a print statement in your main function

void main() {
  print('hello');
}

If that shows up in the logs, that means you're getting all the way to code execution and there's something wrong on the graphics side.

@abarth I changed to just ran that and after redirecting the output of flutter logs I saw that it failed to open a file and create a cache which seems to be used by gpu. I saved the logs in
http://pastebin.com/6YWCmCqb but I think the meaningful lines are the following:

android: E/chromium: [ERROR:browser_gpu_channel_host_factory.cc(258)] Failed to init browser shader disk cache.
android: E/chromium: [ERROR:data_pipe_file_utils.cc(233)] Opening file '/data/data/org.domokit.sky.shell/dev.flx' failed in CopyFromFileHandler::OpenFile

The dev.flx is the file that contains all your code. It looks like we're failing to open that file for some reason. What does adb shell ls /data/data/org.domokit.sky.shell/dev.flx say?

The file isn't there:

○ →  adb shell ls /data/data/org.domokit.sky.shell/dev.flx
/data/data/org.domokit.sky.shell/dev.flx: No such file or directory


○ →  adb shell ls /data/data/org.domokit.sky.shell/
opendir failed, Permission denied


○ →  adb shell ls /data/data/org.domokit.sky.shell
opendir failed, Permission denied

The problem also occurs during the app installation but it wasn't logged with default "flutter start --checked" command, I got this with the following:

Interesting.

adb shell run-as org.domokit.sky.shell chmod 777 /data/data/org.domokit.sky.shell run-as: Package 'org.domokit.sky.shell' is unknown

That's the core of the problem. This command is intended to make the shell's directory writable so that adb shell mv /data/local/tmp/dev.flx /data/data/org.domokit.sky.shell/dev.flx can succeed.

It might be worth trying adb install -r packages/sky_tools/cache/sky_engine/bc1953b81099ad9d14789daa9b6c3426a4278dd3/Release/android-arm/SkyShell.apk manually to reinstall the APK and then seeing if you can use adb shell run-as org.domokit.sky.shell ... to run commands as SkyShell.

I tried few more folders just trying to figure out where I had ACL to read (and its structure) but I got permission denied on all them. I also thought that maybe the app name generated was changed from demo or renamed, as the user doesn't exist from adb command output but I think we tried the reasonable possibilities (I can put the project into the github if you want to see the project, but it is the default demo app) . I got almost the same logs from flutter http://pastebin.com/g3R5aFLt

Thank you for helping me =) I appreciate your help and I'm sorry to depending on you to do each next step but I'm not an expert on adb, android system and flutter =/

I ran all the same commands on OSX 10.11.1 with the same results. I am also on the Samsung Galaxy S6 Edge.

I'm not sure why it thinks the org.domokit.sky.shell package is unknown... That should be the name of the SkyShell.apk package. I think the next step is for me to find an S5 or S6 and try experimenting with it locally. Thanks for helping debug the issue this far.

IMHO, this page describes the problem: http://visualgdb.com/KB/?ProblemID=nopkg

https://code.google.com/p/android/issues/detail?id=58373#c44 describes a workaround, have not tried it yet

I suppose it will have to be good enough for sky_tools to detect this error message and stop with a pointer to issue 58373.

Oh, interesting. Maybe we should fiddle around until we find a package ID with an early-alphabet hash...

The workarounds to make run-as work right are too invasive to reasonably ask people to do.

Why can't SkyShell load the .flx directly from /data/local/tmp/dev.flx?

I have a Xiaomi phone running Android 5.1.1. The hello world app crashes on it too. When I install the app, I get to see the hello world label for just a second and after that it immediately crashes. Re-opening the app only shows a black screen. If I re-install the app, I again get to see the app for a second before it crashes.

See the flutter-dev mailing list where there's a workaround that worked for me. YMMV.

Nice =) So in flutter 0.0.19 will have the fix , right? Thank you guys =D

[Hixie]

(comment stream got truncated in migration, apologies)

[luan-cestari]

Thanks @Hixie . I upgraded flutter to 0.0.18 , I notice in the process that some dependencies have some a newer version but couldn't be upgraded as they have other dependencies and those doesn't have the newer version available.

I think that problem with hash and no ACL to write the app have been solved with the newer version but there still something wrong in the S5 generated app, in the logs mention something about GPU that might be the root cause. I paste the logs in the following gist (so it would be easier to comment something on the file as well) https://gist.github.com/luan-cestari/771cc153faf9f0b885a2

The list of the dependencies that have a newer version:

+ fixnum 0.9.1+2 (0.10.2 available)
+ shelf_route 0.13.5 (0.14.0 available)
+ sky_engine 0.0.49 (0.0.50 available)
+ sky_services 0.0.50 (0.0.51 available)
...
○ → pub upgrade sky_services
Resolving dependencies... (4.2s) 
Package mojo_sdk has no versions that match 0.2.1 derived from:
- sky_services 0.0.51 depends on version 0.2.1

THank you in advance for the help =)

[abarth]

I believe the original issue reported here is fixed. If you're still having trouble with the S5, please open a new issue describing the problem. Thanks!
