ya i googled but how to implement it in app inventor help please

where is jar files for these three which i can import in app inventor extensions

or any other files should i import?

or can some other ways

The android package is just part of Android and so it should be available. javax is a funny beast and the Android buildsystem tends to not like it unless it's already part of the subset of Java that Google has reimplemented. If those aren't supported by default on Android then things are going to get a lot harder for you.

Yes, the OpenGL support is provided standard in Android library and thus is available in extensions.

The android.jar file is already available to you as an extension developer. You don't need to download and include it in your extension. If you're using the extension template, the jar is found at lib/appinventor/android.jar and in the main repository it's located at lib/android/android-29/android.jar.

but should i add edit the `appinventor\components\build.xml for this jar as usuall or is it implemented alderedy i just need to use it ,how to implement it in my code

No, you don't need to change any of the build.xml files to use names from android.jar.

so what should i use in extension code @UsesLibraries(libraries = "WHAT.jar")

You don't have to do anything other than import the classes you need. The Android system provides the implementation of those classes and they're linked at runtime.
