Phenomenon

After upgrading Flash Builder to version 4.7, I found that the previously created ActionScript project was used by default AIR SDK instead of using Flex SDK . This caused my previous project to be unusable. Because some classes rely on the TLF framework provided in the Flex SDK, or only the Spriteassets class such as the Flex SDK.

Viewing the project properties, you will find that the compiler defaults to air SDK 3.4 and cannot be modified:

Solution Solutions

Open the search in the project file with a text editor and .actionScriptProperties useFlashSDK replace its value with false .

Refresh the project once, review the project properties again, and find that the compiler has changed Flex SDK .
