I am working in Eclipse Indigo + Flex Builder 4.5 + Maven + Flash player 11 debugger version in Firefox browser + Flex SDK 4.1, and while debugging in Eclipse the launcher sticks at 57% and then error dialog appears:
The Flash Builder debugger failed to connect to the running application. Ensure that:
- For in-browser applications, you are running the debugger version of Flash Player.
- For network debugging on a mobile device, you have a reliable network connection to the device, and port 7935 is open on your machine's firewall. Device connection help
Also, I have tried almost all the available solutions on the net (like reinstall player, html-template folder, project clean, mm.cfg n all), but nothing helps.
回答1:
Hanging at 57% means that it's failing to connect to the Flash player.
Is your Run/Debug configuration set up to automatically open a page that loads your Flash application? A custom Run/Debug configuration may require you to take whatever action launches the Flash player/plugin.
If that's not the case, have you tried uninstalling the Flash plugin before installing the debug version? Sometimes browsers just can't let go, or switch to the standard version after an update.
