Description

The customer is facing this issue on using *onlink* property of webview. On SDK 8.0.2.GA when webview is created though xml file using onlink property of webview, it provides run time error(android) and the app is crashing on iOS device. *Note:* The customer noticed that *onlink* is working properly only if the webview is created inside the controller. We also tested this. On iOS,it worked properly but on android,it provides run time error. *Test Steps:* 1. Open Studio 2. Copy the sample code and paste via studio 3. Run on android and ios both. The app is crashing on iOS. On android, we got run time error in console. *Test code:* *index.js*

var handleBeforeLoadListener = function(evt) {
	console.log(JSON.stringify(evt));
};


$.webComponent.url = 'webpage.html';

$.index.open();

index.xml

<Alloy>
	<Window class="container">
		<WebView id="webComponent" onlink="handleBeforeLoadListener" />
	</Window>
</Alloy>

*Test Output:* *iOS Crashlog:*

Hello [~gmathews], [~jquick], Can you please look into this issue. We are able to reproduce the issue. Thanks.
Joshua Quick 2019-07-11

[~sdarda], regarding the Android issue, it has nothing to do with "onlink". The "FileNotFoundException" is telling you exactly what's wrong. It's failing to find the HTML file. The issue is the WebView was given a "relative path" to the HTML file. The relative path handling between Android and iOS are different. On Android, file paths are relative to the JavaScript file (or XML file in Alloy) that invoked it. On iOS, file paths are relative to the app's "Resources" directory. The best solution is to give it an "absolute path" to the HTML file. So, the solution is to change this... $.webComponent.url = 'webpage.html'; ...to the below... // Add a leading slash '/' in front of the HTML file path. $.webComponent.url = '/webpage.html'; Using an absolute path as shown above will work on both Android and iOS.

Hello [~jquick], The issue in the iOS is still there after making the above change. App still crashes in open

Can you please try the attached project. Using the absolute path the error in endroid is solved. The iOS crash is still occuring with the 8.0.2.GA SDK. Thanks.

This seems to be a limitation in Alloy. You can't assign functions directly to properties like it is required for onlink. *EDIT:* The workaround i provided before did not work. [~jquick] is currently trying out another solution.

The following will work on both Android and iOS. You should set the onlink callback to empty string in the XML file and then set the onlink property directly in your JavaScript. Also, don't forget the leading slash for the HTML file to reference it by absolute path since relative path handling is different between Android and iOS. index.xml <Alloy> <Window class="container"> <WebView id="webComponent" onlink=""/> </Window> </Alloy> index.js $.webComponent.onlink = function(e) { alert('The onlink callback was successfully invoked.'); return true; // <- Return true to allow link to load. Return false to override. }; $.webComponent.url = '/webpage.html'; $.index.open();

[~sdarda], Jan has deleted his code from his comment in favor of mine. My change will work. Try it out.
Sharif AbuDarda 2019-07-12

Hello [~jquick], your code worked. I have deleted my other reply. Can you confirm what was wrong on the previous code and also in the customer code? If this is a limitation in Alloy as Jan said, any plan on fixing this in the future or maybe document the way of handling onlink in iOS? Thanks for the guide.
