This happens when you don't have the correct provisioning profile on the device (added in iTunes), or you did not sign and package your ipa with the correct profile signature. Also, make sure the app name and id match what you entered when you generated the provisioning profile.
Run through the steps again. It took me a couple tries to get it right...
I use the same provisioning profile and -app.xml with adt and flash builder. My app is ok when i package it with flash builder, but doesn't with adt. Thanks
It works fine for me using ADT in an Ant build. If you post the steps/scripts you're using for the build, I would be happy to take a look at it.
In Flash Builder external tool :
-package -target ipa-test-interpreter -storetype pkcs12 -keystore D:/AMEE/certificats_amee/iphone_dev.p12 -provisioning-profile D:/AMEE/certificats_amee/Developpement_AMEE.mobileprovision ./bin-debug/AMEE.ipa ./bin-debug/AMEE-app.xml -C ./bin-debug/ AMEE.swf -C ./bin-debug/ ca/fujitsu/amee/assets/appicons -extdir "C:/Users/arnalpas/Adobe Flash Builder 4.6/AMEE/libs/"
The program is C:\Program Files\Adobe\Adobe Flash Builder 4.6\sdks\4.6.0\bin\adt.bat and the Working Directory is my project folder.
