Errors in example App #7

Closed Pyreweb closed 9 years ago

Pyreweb commented 9 years ago

Hello,

I just copy-pasted parts of the example app (TiCrosswalk/xwtest/app/controllers/index.js) in mine, and it doesn't work well;

var test = require('com.universalavenue.ticrosswalk');
Ti.API.info("module is => " + test);
Ti.API.info("module example() method returns => " + test.example());
Ti.API.info("module exampleProp is => " + test.exampleProp);

On my Jelly Bean emulator, the output is : 

[INFO]  module is => [object Object]
[ERROR] TiExceptionHandler: (main) [5649,120556] ----- Titanium Javascript Runtime Error -----
[ERROR] TiExceptionHandler: (main) [1,120557] - In alloy/controllers/activite.js:135,66
[ERROR] TiExceptionHandler: (main) [2,120559] - Message: Uncaught TypeError: Object #<TiCrosswalk> has no method 'example'
[ERROR] TiExceptionHandler: (main) [3,120562] - Source:         Ti.API.info("module example() method returns => " + test.example());
[ERROR] V8Exception: Exception occurred at alloy/controllers/activite.js:135: Uncaught TypeError: Object #<TiCrosswalk> has no method 'example'

If I comment the test.example() call, the output is : 

[INFO]  module is => [object Object]
[INFO]  module exampleProp is => undefined

That's the basics; After, I have this, still from the example : 

test.exampleProp = "This is a test value";

var webView = test.createWebView({ html: 'http://universalavenue.com' });
$.actwin.add(webView);

Which gave : 

[INFO]  module is => [object Object]
[INFO]  module exampleProp is => undefined

And the webview is blank, and black.

I installed the module via Gittio only, it may had an impact ?

jonatansberg commented 9 years ago

Hi there, I think that test app is fairly outdated.. To use the WebView in an Alloy project:

<WebView id="webView" platform="ios" />
<WebView id="webView" platform="android" module="com.universalavenue.ticrosswalk" />

Otherwise just call the createWebView([props]) method on the module (when on Android) and use the evalAsync(code, [callback]) method to access the WebView JS context.

On iOS the module simply extends the existing WebView, meaning you can use the same APIs as on Android.

Cheers!

jonatansberg commented 9 years ago

I've added a simple usage section to the README now. If you'd like to fix up the test app as well, feel free to do so! I love pull requests. :smile:

Pyreweb commented 9 years ago

Oh, that's better and far easier :) I may look into updating the example app (if I can make mine work, priorities ;)), it'll help !

Still, not working directly, that'll be too easy

And still a blank and black screen.

And those in particular bugs me : 

[WARN]  BuiltinXWalkExtension: Failed to read JS API file: jsapi/presentation_api.js
[WARN]  BuiltinXWalkExtension: Failed to read JS API file: jsapi/launch_screen_api.js

[WARN]  BuiltinXWalkExtension: Failed to read JS API file: jsapi/device_capabilities_api.js
[WARN]  BuiltinXWalkExtension: Failed to read JS API file: jsapi/messaging_api.js

That's normal ?

jonatansberg commented 9 years ago

The BuiltinXWalkExtension warnings are "normal", or at least I get them too. The real issue seems to be that onCreate lifecycle method is not implemented, a bit further up in the log. What's even more interesting is that I am not getting that error.

Have you tried using the module on an actual device? Implementing a dummy onCreate method (like onStop) might also be a potential fix.

jonatansberg commented 9 years ago

@Pyreweb Here's a custom build with a dummy onCreate method: http://we.tl/ofzy4SofiB

Pyreweb commented 9 years ago

No, I'm using a simulator/emulator actually. Configuration is Android 4.2.2 (Google API's image on ARM), API Level 17.

I'll look on a real device whenever I can.

jonatansberg commented 9 years ago

Ok. Feel free to try the bulid I linked to above. It might fix things for you on the emulator.

Pyreweb commented 9 years ago

Your build indeed fixed the lifecycle bug.

The original issue is now closed ! :smile:
