I am very new to Plugin development. I have an existing NPAPI plugin that works fine on Firefox. I want to reuse it and load it in Safari as well. To get started I downloaded the sample plugin from http://mxr.mozilla.org/mozilla2.0/source/modules/plugin/sdk/samples/basic/mac/. Built it in XCode and added the plugin under /Library/Internet Plugins/. I see that browser notifies asking for permission to access the plugin but I don't see it actually getting loaded. I am doing the following.
var npPlugin = document.createElement("embed");
(npPlugin).type = "application/x-myPlugin";
(npPlugin).data = "data:application/x-myPlugin,";
npPlugin.setAttribute("style", "width:0;height:0");
window.document.body.appendChild(npPlugin);
Couldn't find a good way to debug it, so tried the raw way of creating a file and writing logs to it. I added this to both NP_GetEntryPoints & NP_Initialize with a hope that one of these functions will be invoked at the time of loading and will log for me. I didn't see any signs of my plugin getting loaded. Any ideas on how to make it to load or how to actually debug it?
I commented out any code that was other than the NPAPI required methods. It helped me get around this problem.

I've built a simple Android app, as a companion piece to a publication website, with the Ionic framework, and (after much head-banging), I managed to get the Disqus threads on the app to sync with those on the site. After trying a few different methods, I ended up going with this directive from Michael Bromley to implement the Disqus widget in the app, which is hiding behind a "Comments" button at the bottom of each article on the app's UI.
Running with Ionic Serve, everything works brilliantly. Outside of the local server: not so much. I don't get an error message from Disqus – it simply doesn't load the iframe at all. I'm refraining from posting code, because I'm wondering if this is simply a CORS issue, or maybe something simple that I'm overlooking.
One thing that might be of importance: I don't have the Crosswalk plugin installed on the app – I'm not sure if my thinking is correct, here, but could it be possible that Disqus is compatible with Chrome, which is why it runs fine when I'm testing it on my browser, but isn't compatible with Android's default browser? I'm not extremely well-read on Crosswalk, but I believe it tells the app to use a specific browser – if so, could installing it fix the problem? I'd go ahead and install it, and see if it helps, but I'd like to avoid tampering too much with an otherwise-working app if the issue is something completely unrelated to the plugins.
One weird caveat: The Disqus comments loaded on one article just fine when I tested the app on Genymotion. I deleted that article, and created a new Test article on my site (thus firing up a new Disqus thread), and that failed to render on Genymotion. It seems very... random, I guess, that it would work once. It would seem that it would either work all the time, or never work.
EDIT: While running on Genymotion, no errors appear in the console when debugging the app with WebView. The fact that I'm not getting a "Refused to load" error makes me think that Disqus is getting called and, for whatever reason, is refusing to answer the phone at all.
I can spend hours trying to figure something out, and then... well, as soon as I post a question, I end up figuring out the answer five minutes later.
I dug looked into the code for the directive I was using (which I highly recommend for anybody looking to easily implement Disqus into any AngularJS project), and I noticed that was calling for embed.js with the following string:
....
if (!$window.DISQUS) {
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
dsq.src = '//' + scope.config.disqus_shortname + '.disqus.com/embed.js';
(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
} else {
....
Amending dsq.src = '//' + scope.config.disqus_shortname + '.disqus.com/embed.js';to add a protocol, making it dsq.src = 'http://' + scope.config.disqus_shortname + '.disqus.com/embed.js';fixed the issue on Genymotion. I'll ship the updated APK to the Play Store, and comment on this answer to confirm whether or not it holds up there, as well.
Adobe AIR application which was working perfectly earlier; is not working now. No idea whether it is due to any recent change in Facebook or Adobe AIR.
I have added the component mx:HTML to display http://facebook.com content. In the development environment (Flash Builder 4.5) after logging in facebook successfully; I can see the TimeLine contents and updates properly. But after build when executed outside the IDE; I am able to login facebook but the timeline or updates are not being displayed properly.
Anybody facing similar issue and has a fix; please provide the solution.
uncaughtScriptException gives following two errors...
TypeError: Result of expression 'bigPipe' [undefined] is not an object.
ReferenceError: Can't find variable: console
I have similar issue, if you catch the javascript errors you will notice that facebook is using some library that fails in AIR, then if you google that exact error you will find similar issues. My solution was to use the FB API and reimplement the functionality(in my case share) , other alternatives is to fix that library or FB code to make it work. I don't remember the details but I fixed it a week ago.
Check the docs for catching the JS errors uncaughtScriptException
I am wondering if that library has code for each browser that it supports and on AIR it fails, maybe changing useragent will help, you need to check the javascript code to see where it fails
I've being trying to implement a native File picker on BlackBerry 10 today, I linked it against the required Library -lbbcascadespickers
Included <bb/cascades/pickers/FilePicker> that links to the FilePicker.hpp class and all seems fine, but when I try to create a new File picker it says "error: 'FilePicker' was not declared in this scope"
Code is as follows:
FilePicker* filePicker = new FilePicker();
filePicker->setType(FileType::Picture);
filePicker->setTitle("Select Picture");
filePicker->setMode(FilePickerMode::Picker);
filePicker->open();
// Connect the fileSelected() signal with the slot.
QObject::connect(filePicker,
SIGNAL(fileSelected(const QStringList&)),
this,
SLOT(onFileSelected(const QStringList&)));
// Connect the canceled() signal with the slot.
QObject::connect(filePicker,
SIGNAL(canceled()),
this,
SLOT(onCanceled()));
I'm brand new to BlackBerry development so don't really know what to do, I've cleaned the project and built it many times but it won't play.
I was going by the example on BlackBerry's website:
https://developer.blackberry.com/native/reference/cascades/bb_cascades_pickers__filepicker.html
I wanted to open it from QML (I'm using Qt Quick and not BB components)
If anyone can help it will be deeply appreciated
The compiler can't find FilePicker. So either use a using to tell the compiler where to look:
using namespace bb::cascades::pickers;
or fully qualify the name of the class:
bb::cascades::pickers::FilePicker* filePicker = new FilePicker();
I have a anchor tag with the url "itms://itunes.apple.com/us/app/movietickets-com-showtimes/id402114309?mt=8".If the client system doen't have the Itune software, then the browser is not opening the page.
Is there any way to know the whether the user installed Itune software or not.
Thanks in advance.
Note:
If you go to
https://itunes.apple.com/us/app/movietickets-com-showtimes/id402114309?mt=8
Here you can find or inspect "view in itune" button.There you can see
some javascript to detect that.But i dont know what there are doing!
Apple already has code to detect if iTunes is installed, you can find their code here: http://ax.itunes.apple.com/detection/itmsCheck.js
Finally i got a solution,
From the following site https://itunes.apple.com/us/app/movietickets.com-showtimes/id402114309?mt=8
You need to take two js files. (It contains some extra javascript and jquery - you can remove those if you know that it is no longer needed)
https://itunes.apple.com/htmlResources/99EF/web-storefront-base.js
https://itunes.apple.com/htmlResources/99EF/web-storefront-preview.js
And you need to add the below code to your page html,
""
Finally, Whenever you want to check the plugin, just call
if (its.detect.itunesDetected())
{
//Your code if plugin installed
}
else
{
//Your code if plugin not installed
}
Can any expert here please point me to some valid walkthrough on how to make the ChildBrowser work with Cordova 1.7 in iPhone? I have found lots of documents and blogs out there that tell you how to do it, but none of them have worked for me. It is not a whitelist issue for sure, as for the time being I have set it to the wildcard *, so whitelisting problems can be safely ruled out I guess. In some cases, ChildBrowser was successfully installed, but when I called the showwebpage function, it just would not show up (there wouldn't be any errors either!). Other times, it just won't even install. I have already spent 2 days on it, and am still clueless. Just hoping if you could help me out. Any help would be appreciated.
I could finally get the ChildBrowser to open up following what Dhawal has suggested below. But the onLocationChange event never seems to fire. Again, this seems to be a common problem with Cordova 1.7. Any workarounds apart from rolling back to some older Cordova version? Any help would be appreciated.
Here's what I am trying to do:
window.plugins.childBrowser.showWebPage(url, { showLocationBar: true });
window.plugins.childBrowser.onLocationChange = function(loc){ alert("In index.html new loc = " + loc); };
Ok, got it to work. Seems like ChildBrowser is still compatible with older versions of Cordova only. Had to delve into Objective-C and make changes in the plugin to make it work.
I have a basic application which has childbrowser integration with Cordova 1.7. I have put the steps also to generate build same application.
ios-cordova-childbrowser
Edit
Childbrowser events were not getting called properly so I added this fix in ChildBrowser.js file to resolve it.
if (cordovaRef && cordovaRef.addConstructor) {
cordovaRef.addConstructor(ChildBrowser.install);
// Make ChildBrowser global
window.ChildBrowser = ChildBrowser;
} else {
console.log("ChildBrowser Cordova Plugin could not be installed.");
return null;
}
