old dx.jar in AIR SDK

[myflashlab]

Problem Description

The dx.jar file located at /Users/user/Documents/AIR_30.107/lib/android/bin/dx.jar is too old and needs to be updated to at least V27.0.3. Some third party Android libraries like the tensorflow library will throw an error like below:

This will be a problem when developing ANEs like Firebase MLKIT which are using tensorflow library.

Steps to Reproduce:

Include the following ANE in your project and try to compile your AIR app. you will see the above error message.

<extensionID>com.myflashlab.air.extensions.dependency.tensorflow</extensionID>

Workarounds:

You could bypass the problem by overwritting the dx.jar file from the one in Android SDK /Users/user/Library/Android/sdk/build-tools/27.0.3/lib/dx.jar. This will solve the problem. but still, it makes sense if the AIR SDK has the latest version itself.

Seems Adobe need consistent reminders to update the Android build tools, I think we've already been through 2 or 3 requests for this. Hopefully they are quicker this time.
