Hi Matthew, we could successfully build a Java extension-enabled app using Crosswalk 5 on ARM, with the Crosswalk app template version you are using, by following the instructions on the wiki.
>From the error message, based on the information provided it would seem that >the class file for your extension is not in the jar file (even though the jar >file is there). If you have any more details you can share to help reproduce the issue that would be great. Kind regards, Francesco From: Crosswalk-help [mailto:[email protected]] On Behalf Of Matthew Sun Sent: Sunday, February 02, 2014 5:44 PM To: [email protected] Subject: [Crosswalk-help] Extensions Hi I have been developing using crosswalk-5.32.81.0-arm and find it quite good. Except now I need to write some extensions, so I followed the instructions here https://crosswalk-project.org/#wiki/Writing-a-Crosswalk-Java-Extension-on-Android I followed them exactly, and built my apk with the additional --extensions="/path/to/myextension/". There was no build errors, and the xwalk-extensions folder even showed up in the created folder, along with the appropriate jar file inside. Problem is, once running the app on a device the following error is generated by XWalkExtensionManager and the extension never fires "Error in calling methods of external extensions. java.lang.ClassNotFoundException: Didn't find class "com.example.extension.MyExtension" on path: DexPathList[[zip file "/data/app/sunnyappz.coolmathsalgebragame-1.apk"],nativeLibraryDirectories=[/data/app-lib/sunnyappz.coolmathsalgebragame-1, /vendor/lib, /system/lib]]" Any guidance would be much appreciated. Does anyone else have extensions working using the instructions given? Is there something I need to watch out for.
