Thank u,J. I think the recompiled java code runs on Dalvik performance worse than native code, but I don't know the performance compare Dalvik with some other VM used Jazelle. And the memory required, how much is best balanced between cost and performance? Is there any open source Java ME VM use Jazelle?
