crashes when you rotate the device #9

Closed hayksaakian closed 9 years ago

hayksaakian commented 10 years ago

i've got it working, albeit sluggishly, and it seems to crash now whenever the screen rotation changes.

see logcat:

Exactly the same problem - any suggestions?

hayksaakian commented 10 years ago

My solution was to avoid this library for now.

Find whatever features you need from chromium web view as standalone libraries and hook into the normal web view with JavaScript interface.

VeeruPV commented 10 years ago

That does'nt really sound like a solution :) Chromium works fine for what i need to do (load a html 5 page with sockets) - any other alternatives? i cannot really change the html 5 page.

hayksaakian commented 10 years ago

Essentially what you would do is implement the API you need in Java and then write a wrapper for it in JavaScript.

Android has a way to hook into java from JavaScript. Look into @JavascriptInterface annotation.

I personally did this for implementing websockets in an app of mine. On Mar 3, 2014 8:25 PM, "VeeruPV" notifications@github.com wrote:

Thanks for the headup, but that sounds greek to. Any direction that you can recommend? The websockets are already a part of the html5 page, and all i need is to get it working inside a webview

hayksaakian commented 10 years ago

the easiest way (assuming your whole android app is a webview) is to use cordova/phonegap

they have a custom webview that includes things like websockets

No, that is not the case, it is a native app, with one screen showing a webview, with the mentioned sockets in it.

hayksaakian commented 10 years ago

i had to solve the same exact problem in one of my apps

look at this class, and follow the bread crumbs

https://github.com/destinygg/android/blob/destinyapp/src/gg/destiny/app/support/WebViewClientWithWebSockets.java

it comes down to what i said

1) java webview client that implements websocket functionality in java 2) javascript file that implements the websocket API client (with hooks into java) 3) inject the JS file into the webview on page load with a custom webviewclient

it's a pretty hot mess

if i had to do it again, i would simply include cordova into my project, and use a cordova webview instead
