Well, I can also help you.

  1. Download Sources
  2. As you are extension dev, you may have most of required variables in ur path.
  3. Download Google Cloud Sdk and add it in your paths
    https://cloud.google.com/sdk/docs/install
  4. Run ant in appinventor folder ( It may take 15-30 mins)
  5. After Build Successfull, run this command git submodule update --init and then run this command
    java_dev_appserver --port=8888 --address=0.0.0.0 appengine/build/war/ in appinventor sources folder.
  6. Navigate to localhost:8888
  7. Login to it with test@example.com ( or any of your preference)
  8. You are done ! Now u can modify UI and Logo. You can also add new comps as mentioned in many guides.

If any doubt, feel free to ask
Regards

Make sure u ran ant MakeAuthKey

I don't think that's going to be enough. Typically we need at least 4 GB of RAM to compile the App Inventor frontend these days unless you disable collapsing all properties (which has the side effect of increasing the build times).

You mention extension development, so if that's what you're going for I would recommend using the extension template repository, which will build much faster than the main repo since most things are precompiled for you.

@HIFI_Apps mine compilation failed when I use Xmx1024M but succeeded when I used Xmx2048M, it compiled it means it needs atleast 2 gb of ram to compile and if ur pc is having 2 gb ram, then how will it do so

13

Ok my pc is going to die\burst so I will change the ram that time.

14

Yes now my ram is 4gb i am with ne hard disk so i setup my pc with environmental variable and now the app inventor sources can compile my extension.

so i started creating app inventor
now i am at this step the out put of ant MakeAuthKey

Yes, these are just warnings about the configuration of the build. They will not interfere with anything else.
