Extension Template Repository

I’ve updated the template to include the version of Kawa from appinventor-sources. That should fix the issue.

I tried to import this:

import android.support.v4.content.FileProvider;

and get this error:

I didn't pull in all of the android-support libraries from App Inventor, but if you also have the appinventor-sources checked out you can copy them from lib/android/support/ so everything is available to your extension.

Because the support libraries are baked into every app, doing this will cause dx to fail compilation due to duplicate classes since it will come once from the buildserver and once from the extension.

Thanks, I deleted my post as to not create confusion/issues.

No worries. Adding the library is usually the right behavior. I don't know why Android/Google chose not to handle copies of the exact same class during compilation, but it causes many headaches.

Thank you, successfully done.

@ewpatton Can you please update the Extension Template Respository (→ AndroidX).

I got this error:

Just replace android lib with androidx lib.

That's not the only thing that needs to be changed. In fact the android.jar present in lib directory is very different from AndroidX, and there exists no such thing as a single AndroidX library. It is a collection of different libraries, altogether known as AndroidX libraries.

In addition to that, there were quite a lot changes done in nb184 release, so, other files needs to be updated as well to reflect these changes.

Someone can explain me what's the difference between building an extension with this and building with app Inventor source code? What are the pros and cons?

Thanks in advance.

See e.g. here:

Is there still hope for an update to the AndroidX lib (in the near future)? @ewpatton

@yusufcihan also extension templete compiles extension in 10 to 15 seconds

The extension template repository has been updated to support the latest version of App Inventor (v185). With this change I've split the repository into two parts. All of the App Inventor dependencies are now published in a separate repository at https://github.com/mit-cml/extension-deps. The template repository stores a reference to that repository through a git submodule dependency.

  • If you merge from this repo to get an update, you should run git submodule update --init after merging to get the dependencies.
  • If you're cloning a fresh template, GitHub seems to drop the submodule. In this case, run the upgrade-appinventor.sh script included in the repository to get the dependencies.

As we release new versions of the App Inventor companion, developers should run upgrade-appinventor.sh to ensure they compile their extensions against the latest version of App Inventor.
