As we promised we are back with a tutorial on how to build Flex applications for Astro flash player. This will be a step by step tutorial which is intended to help you install the last Flex SDK from daily builds. So let’s start…

1) Get the Flex SDK Daily build.

2) Create a new folder: “3.0.1.1739“.

3) And put everything in it.

4) Open Flex Builder 3 and open Window/Preferences, then select expand Flex and choose Installed SDKs. Press Add.

5) Browse to the folder we created at 2) and give a name to the new SDK: “Flex 3.0.1.1739“.

6) Select it as default SDK.

7) Make all compiles target player 10.

- Modify FLEX_SDK/frameworks/flex-config.xml. Edit , replacing 9.0.115 with 10.0.0:

<target-player>10.0.0</target-player>

- In <external-library-path>, edit the path-element for playerglobal.swc, replacing 9 with 10:

<external-library-path>
    <path-element>libs/player/10/playerglobal.swc</path-element>
</external-library-path>

- Do the same with <library-path>:

<library-path>
    <path-element>libs</path-element>
    <path-element>libs/player/10</path-element>
    <path-element>locale/{locale}</path-element>
</library-path>

At this moment you should be able to have code hints and every project should compile for Astro.

Now create a new Flex Project. Right click on it and open its properties. Change values as in the image bellow.

To see it work you should have Flash Player 10 installed.

There is a undocumented standalone Flash Player 10 version with debug. Check it here.
