Solution to error 41 during Android Compilation

I encountered this error. I saw the solution in a Foreign Forum and successfully solved the problem. I hope to help others.

Error:
Build/CORE/product_config.mk: 229: Warning: adding test OTA key
Host Java: clearsilver (Out/host/common/obj/java_libraries/
Clearsilver_intermediates/classes)
Unrecognized option: 9999999
Make: *** [out/host/common/obj/java_libraries/
Clearsilver_intermediates/javalib. jar] Error 41

Cause:
According to the error message, it is probably a Java Virtual Machine problem. Some people say that I have installed Java, but it cannot be used. "androidrequires at least java5 with update 12...", I installed Java 6, no problem.

Solution:
After installing Java 6
1. Configure the Java environment variable. I installed it with the new version in ubuntu8.04. The default path is/usr/lib/JVM/Java-6-sun.
Open the. bashrc file under the root user
# Vi ~ /. Bashrc
Add

Export java_home =/usr/lib/JVM/Java-6-sun
Export android_java_home = $ java_home

Save and exit

2. Use the update-alternatives command to change the correct path to the Java service. Because we may have installed several services that can provide Java, although Java 6 is installed, the path has not been changed, the system still uses the old path, so during Android editing, the version is incorrect.
Modification example (replace alternatives with update-alternatives in Ubuntu ):
[Root @ vostro ~] # Alternatives -- config Java
There are 3 programs which provide 'java '.
Selection command
-----------------------------------------------
* + 1/usr/lib/JVM/jre-1.6.0-openjdk/bin/Java
2/usr/lib/JVM/jre-1.5.0-gcj/bin/Java
3/usr/Java/jdk1.6.0 _ 07/bin/Java
Enter to keep the current selection [+], or type selection number: 3

[Root @ vostro ~] # Alternatives -- config javac

There is 1 program that provides 'javac '.
Selection command
-----------------------------------------------
* + 1/usr/lib/JVM/java-1.5.0-gcj/bin/javac
Enter to keep the current selection [+], or type selection Number:
[Root @ vostro ~] # Alternatives -- config javac
There are 2 programs which provide 'javac '.
Selection command
-----------------------------------------------
* + 1/usr/lib/JVM/java-1.5.0-gcj/bin/javac
2/usr/Java/jdk1.6.0 _ 07/bin/javac
Enter to keep the current selection [+], or type selection number: 2

[Root @ vostro ~] # Javac-version
Javac 1.6.0 _ 07

[Root @ vostro ~] # Alternatives -- config jar

There is 1 program that provides 'jar '.
Selection command
-----------------------------------------------
* + 1/usr/Java/jdk1.6.0 _ 07/bin/jar
Enter to keep the current selection [+], or type selection Number:

Provide Java, javac, change all program paths of the jar service to jdk1.6.0 _ 07 (my files are/usr/lib/JVM/Java-6-sun/JRE/bin/Java ), that is, * and + are all moved to that location. In my system, only default selection can be changed. Later, I deleted other paths using Update-alternatives -- remove, current selection [+] has been changed. How to delete it is helpful.

Finally, restart (logout/login may be required) to make the job. Enjoy it
