What's New in MoSync Reload Beta (Previous Release Notes)

Support for Remote Logging

Android, iOS and Windows Phone 7

Debugging your apps can be difficult without the proper tools. That's why we have introduced a remote logging feature, remote log, in MoSync Reload. Just add your rlog statements in your HTML5 and JavaScript code and whenever the application hits that line your logging information will be displayed in the Reload Server.

Note: The debugging features would only work on iOS 5.0 and above, to use reload client with older versions of iOS please get it from the App Store.
