Android Question SDK Manager Does Not Launch

[DavidTheGeek]

Hello

When I click in the SDK Manager option in Tools (or in the Configure Paths window) nothing happens.

I need it because I'm trying,

https://www.b4x.com/android/forum/t...n-very-simple-to-use-barcode-scanning.160725/

and the instructions say to use it.

My B4A version is 12.80 installed according to the instructions.

My B4A version is 12.80 installed according to the instructions.

when did you installed the SDK exactly? Or: when did you installed the SDK the last time
You are member since a few years...

Can you post a screenshot of the Paths configuration in your IDE?

A couple of weeks ago, on a new PC...

Probably not related to this problem, but the Java path should not be inside Program Files when using OpenJDK.
Better something like
C:\Java

You are not using the correct Java.

Carefully follow the installation instructions: https://www.b4x.com/b4a.html

Hi

I'm using the Java suggested as the (successful) solution to this problem:

Finding libraries that need to be dexed. (0.00s)
Dex code Error
Error in C:\Users\David\Documents\B4A\Projects\Tester\B4A\Objects\bin\classes\b4a\example\main$B4AMenuItemsClickListener.class:
java.lang.NullPointerException: Cannot invoke "String.length()" because "<parameter1>" is null
Compilation failed with an internal error.

The solution is in this post: https://www.b4x.com/android/forum/threads/project-for-today.158941/post-976314

If there is an alternative solution to the compile error using the correct Java, of course I'd happily adopt it.

The correct instructions are here: https://www.b4x.com/b4a.html

Thank you for your patience. I did that and SDK Manager now launches, but a search for "mlkit" yields no results:

Do I have to configure something else?

Do I have to configure something else?

you forgot to set the path to the sdkmanager.bat
See at top of the SDKManager and set the path.

Select the one from the sdk path you just installed.
