[Orekit Developers] [SOCIS] problem converting a jar to android

[MAISONOBE Luc <luc.maisonobe@c-s.fr>]

Hello,

I tried to use the "easy way" instructions here:  
<https://www.orekit.org/forge/projects/socis-2011/wiki/HowToBuildToAndroid> to  
convert a simple standalone jar file to check loading performances  
(see <https://issues.apache.org/jira/browse/MATH-650>).

I created the initial jar, checked it worked well in a Java  
environment under Linux, converted it to android using the dx program  
and tried to run it on the tablet. I did it on the tablet using a  
terminal application, not adb shell because I have some USB problems  
with my tablet.

the command:
 dalvikvm -classpath test.jar org.apache.commons.math.LucTestPerformance

produced the following error:

Dalvik VM unable to locate class 'org/apache/commons/math/LucTestPerformance'
java.lang.NoClassDefFoundError: org.apache.commons.math.LucTestPerformance
        at dalvik.system.NativeStart.main(Native Method)
Caused by: java.lang.ClassNotFoundException:  
org.apache.commons.math.LucTestPerformance in loader  
dalvik.system.PathClassLoader[test.jar]
        at: dalvik.system.PathClassLoader.fincClass(PathClassLoader.java:251)
        at: java.lang.ClassLoader.loadClass(ClassLoader.java:548)
        at: java.lang.ClassLoader.loadClass(ClassLoader.java:508)
        ... 1 more

I have looked inside the converted jar. It contains several html files  
and a large classes.dex file. I was not able to open this dex file bu  
running the "strings" unix command on it shows all the class names I  
expected, including the main one. The manifest file also specifies the  
main class is the one I pass on the command line (it seems I must  
provide this name despite it is already in the manifest).

Any idea about what I am doing wrong ?

My tablet is running Android 3.0 and DalvikVM is version 1.5.0.
