david,
i have modified my project according to your suggestion.
<1> remove the following
//#include <stdio.h>
//printf("hello testjni\n");
<2> add simple calculation function
but the problem exist yet.
ps:
HelloAndroid.apk is build in android-sdk with eclipse under windows.
libtestjni.so is build under linux.
i don't think there is trouble thus.
