> How to proceed from here? Where is the sdk (created by the sdkUpdater bat) located?

The Android SDK ends up in your _sketchbook folder_.

References:  
[Environment / Processing.org](https://processing.org/environment)

_ **After the SDK is installed…** _  
I had to _Locate SDK path manually_ before running a sketch.

_ **Try this:** _  
Run a sketch. Close Processing. Run a sketch… repeat.  
This seemed to work on W11 after a few passes and was save to the _Preferences_ and I did not have to select any more.

\*\*\* **IMPORTANT** \*\*\*

Using the _sdkUpdater.bat_ is for advanced users.

The _sdkUpdater.bat_ was a workaround only!

Important distinction:

- You downloaded the SDK.
- The _sdkUpdater.bat_ _ **workaround** _ updates the SDK so that it can be used to compile without errors.
