Flash Builder 4.7 fails on debugging on android device

StackOverflow https://stackoverflow.com/questions/17831511

Question

I'm creating an app including native extensions (.ane)

At the moment it's already working on iOS, but I want to add an extension for android as well.

Now, i've done all necessary steps to do so and want to debug on a device. But whenever I try to start the Debugger, I get the following error, and I don't know how to fix this.

I am able to create a 'release build', though. Unfortunately, after startup, the app hangs.

I do not know, however, if it's a building or a coding issue causing the crash, therefore I need the Debugger.

An internal error occurred during: "Launching MyAppWithExtension".

Many Thanks in advance, Timm

EDIT: This is what I've done so far, but no luck :(

  • Created new workspace

  • Run Flash Builder with -clean parameter at startup

  • Reinistalled Flash Builder using Adobe Clean Tool

  • cleaned all bin-debug bin-release-temp and other project related temp folders I'm aware of.

Was it helpful?

Solution 2

After weeks of experimenting, I finally found the reason for the problem. It seems Flash Builder had problems with the structure of my project, namely I had 2 executable applications in it.

Removing one, either by deleting or by deactivating over the Project->Settings->Applications dialog, finally fixed it.

I hope this helps anybody facing the same annoying Flash Builder issue.

OTHER TIPS

  • How does you appName-app.xml looks like? Look at the end of the file, does the <extensionID> match the ANE/extension.xml <extension>/<id>?
  • Did you build your ANE with the same sdk than your main project?
  • Are the files referenced by <nativeLibrary> really included in the ANE (open it with an archiver)?
  • Did you well implement functions referenced in extension.xml's <initializer> & <finalizer>?

In case you have this exception when using an ANE AND a Coldfusion Server, change the Output folder in the Project Properties > Flex Server > Output folder to something like "temp" instead of "C:..." generated by Flex Builder. The Android device gets confused by a "C:" reference but still can understand a "temp" local folder
