Pre-Dexing Android Build error

Troubleshooting android
1

Hi, I’m new in jmonkey, I created a scene with a rotating 3D object, and now i want to compile for android.

Everything is perfect untill this:

Pre-Dexing E:\Games\ANDROIDSDK\New\BasicGame\mobile\libs\jME3-jogg.jar -> jME3-jogg-05260a7b23146c2959eb41e7e8cc33ff.jar
reg is not recognized as an internal or external command, operable program or batch file.
E:\Games\ANDROIDSDK\New\BasicGame\nbproject\mobile-impl.xml:21: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:892: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:894: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:906: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:283: null returned: 255
BUILD FAILED (total time: 5 seconds)

What’s wrong with my project?

mobile-impl.xml line 21 looks like this: <ant dir=“mobile” target=“release” inheritall=“false”/>
The build.xml lines are in a function that “Converts this project’s .class files into .dex files”

I installed the 64 version of Jmonkey and java… But I only found the x86 version for Android SDK. I’m using Windows 7 64.

Thanks a lot.

Can you post your manifest.xml?

and the entire mobile-impl.xml

Well… used this build.xml: http://hub.jmonkeyengine.org/forum/topic/android-and-proguard/

Nearly got it… The last error I hope is this:

Custom Target -copy-project-libs
E:\Games\ANDROIDSDK\Test\BasicGame\build.xml:20: The following error occurred while executing this line:
E:\Games\ANDROIDSDK\Test\BasicGame\build.xml:32: Warning: Could not find resource file "E:\Games\ANDROIDSDK\Test\BasicGame\{run.classpath.without.build.classes.dir}" to copy.
BUILD FAILED (total time: 2 seconds)

Tried everything, and different projects… no luck.
