Android Question Cannot get B4A working from scratch.

[F800GT]

Fresh install of B4A 13.50 to C:\B4A.

Hi Gents.
This thing is not Basic IMHO as I have been trying to get it working for 3 days now and Mr C GTP cannot help so I am
appealing to the experts.

This is where I am at.

Configure Paths:

• javac.exe = C:\Program Files\Eclipse Adoptium\jdk-25.0.3.9-hotspot\bin\javac.exe
• android.jar = C:\Android\SDK\platforms\android-34\android.jar
• Additional Libraries = empty
• Shared Modules = empty

Android SDK:

• build-tools\34.0.0 exists
• platforms\android-34 exists

Created a brand-new B4XPages project.
Only Core and B4XPages are selected.

Build log:

B4A Version: 13.50
Parsing code.
Java Version: 8
Building folders structure.
Running custom action.
Compiling code.
Compiling layouts code.
Organizing libraries. Error
Maven artifact not found: com.android.support/multidex
Source: com.android.support

What puzzles me is that the build log reports Java Version: 8 even though javac.exe points to Java 25.

You are using wrong version of Android SDK and wrong version of Java. It shouldn't be 8 nor 25.
