Are you running it from B4J?

Which version of Java?

What is the SDK path?

Yes, I'm running from B4J, but the log show wrong Java Path. My computer have install java8 - C:\Pragram File\Java, but log show C:\java

It uses the same Java that B4J uses (when you run it from B4J). It is configurable under Tools - Configure Paths.

Error from SDK Manager v3.32. Error is start to appear after upgrade to B4A v9.01:

Error: Error: Could not find or load main class com.android.sdklib.tool.sdkmanager.SdkManagerCli

I have both Java 8 and OpenJDK 11. B4A use OpenJDK 11.
From B4J log:

DataFolder: C:\Users\XXXXX\AppData\Roaming\B4ASdkManager
Java Path: C:\Program Files\Java\jdk1.8.0_102\jre

Error when running v3.32 from B4A Tools -> SDK Manager:

Error: Error: Could not find or load main class com.android.sdklib.tool.sdkmanager.SdkManagerCli
Caused by: java.lang.ClassNotFoundException: com.android.sdklib.tool.sdkmanager.SdkManagerCli

If I debug SDK Manager in B4J error is triggered in the Main module on line 318:
Sucess = True, ErrorCode = 1

Your Java path under tools should point to the BIN folder not the jre folder
eg. C:\Program Files (x86)\Java\jdk1.8.0_201\bin\javac.exe

My path is OK, I will not be able to compile app.
Also change path to OpenJDK got similar error when starter from B4A described in my previous post.

Weird - I downloaded that last night setting up a new laptop & had no issues.

I see the problem. It should work properly if you are using the latest version of Android SDK (build tools 26.0.0)

I will make an update to B4A so it won't break older versions of the SDK. sdkmanager.bat and avdmanager.bat from version 25.3.1 are attached. You can use them if you want to keep the old version of Android SDK with Java 8.

Pendrush · Apr 18, 2019

SDK Manager v3.33 (B4A v9.0.1.1) work properly with path set to Java 8, but still get same error with OpenJDK 11.
How can I get the latest version of Android SDK (build tools 26.0.0)?

EDIT:
My latest installed build tools inside SDK Manager is Android SDK Build-Tools v27.0.1.

Erel · Apr 18, 2019

Open tools\source.properties
The version should be: Pkg.Revision=26.1.1
The older one I have here shows 26.0.1.

You need to download it from: https://dl.google.com/android/repository/sdk-tools-windows-4333796.zip
