Android Question Error while compiling with android.jar

[Yayou49]

Hi,

Today I've updated all stuff about Java on my computer.
Remove all and reinstall the last version of Java and SDK (jdk-8u72-windows-x64 and installer_r23.0.2-windows)
I didn't do anything on B4A stuff.
The only different thing is the path where SDK has been installed.
It has been install in C:\Program Files (x86)\Business Objects\javasdk\bin\
(I've ran the install without changing anything)

Now, while compiling, I've got this error:

B4A version: 5.50
Parsing code.  (0.04s)
Compiling code.  (0.21s)
Compiling layouts code.  (0.05s)
Generating R file.  (0.04s)
Compiling debugger engine code.  Error

bad class file: C:\Users\Me\AppData\Local\Android\android-sdk\platforms\android-23\android.jar(java/io/IOException.class)
class file has wrong version 51.0, should be 49.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import java.io.IOException;
  ^
1 error

What to do with this ???

PS: My path are well set
Javac.exe:
C:\Program Files (x86)\Business Objects\javasdk\bin\javac.exe
android.jar:
C:\Users\Me\AppData\Local\Android\android-sdk\platforms\android-23\android.jar

Android SDK Tools: Rev.24.4.1
Android SDK Platform-Tools Rev.23.1
Android SDK Build Tools Rev.23.0.2

Hello,
Unsure but from what I can read on the error message, it could be that the SDK is not the one you have installed in "C:\Program Files (x86)\Business Objects\javasdk\bin\" ? Perhaps could you take a look to your Windows system globals ?

You are using Java 5. You should switch to Java 7 or 8 (Tools - Configure Paths).

 

[Yayou49]

I agree, but after the install of the last Java, I cannot find javaC.exe ... (the one needed by b4A)
I can see only java.exe or javacpl.exe
(java.exe is a version 8)
Do you have a link to be sure to download the good version of java ?

 

[Erel]

This means that you have installed Java JRE (runtime) instead of Java JDK.

All the links you need are available here: https://www.b4x.com/b4a.html

I'm in a big mess ....

Well, I've removed everything about java once again.

I've done step by step what is in your link:
- download jdk-8u72-windows-x64
- run it in a specific folder
First problem:
javac.exe is not in this folder ....

- run the installer_r23.0.2-Windows
and set the appropriate things whith API23

The only way for me to retreive javac.exe is to run JavaSetup8u71.exe and then I found it in path C:\Program Files\Java\jdk1.8.0_72\bin

If I try to compile my project, now I've got a new error:

B4A version: 5.50

What's wrong with my install ????

 

[Yayou49]

Well, I've uninstall B4A and then reinstall and now IT WORKS !!!!
However, I need to know why javac.exe is not in SDK folder ???
Because without using JavaSetup8u71.exe, I was not able to set the correct path in B4A for the javac.exe ....

Now it works, so it's not a big problem, but it's just for me to understand

Anyway, thanks Erel for your help, you were still MASTER of MASTER

javac is part of Java JDK, not Android SDK.
