On Android: java.lang.OutOfMemoryError: Java heap space

[Former user]

I had an earlier version of symja used in one of my android applications. and it works fine. the one of symja-2014-01-19.jar gives me this error no matter i increase the memory size for the compiler's sake.

The error:

I'm using these settings. Could you please try if it works for you?

--launcher.XXMaxPermSize

256M

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

256m

--launcher.defaultAction

openFile

-vmargs

-Dosgi.requiredJavaVersion=1.6

-Dhelp.lucene.tokenizer=standard

-Xms256m

-Xmx1024m

I copied it verbatim. It did not work. I and I have 4GB of RAM and Intel i7 CPU.

With the ANT script

/symja_android_library/build.xml

you can compress the library with proguard and use the created JAR

symja_android_library\symja_android_library\build\jar\symja-mini-2014-xx-xx.jar

Problem is that at the moment some method names are obfuscated by this script.
