According the article "Android - Invoke JNI based methods (Bridging C/C
++ and Java)", I change the steps of building library
first, copy and modify the linker script armelf_linux_eabi.xsc by the
article,
second, build library as follows:
arm-none-linux-gnueabi-gcc -I/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/
include/linux/ -I/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/include -fpic -c
project_testjni_TestJNI.c
arm-none-linux-gnueabi-ld -T armelf_linux_eabi.xsc -shared -o
libNativeAdd.so project_testjni_TestJNI.o
But while running loadLibrary("libNativeAdd"), the same as before, it
throw a "UnsatisfiedLinkError" exception.
I search keyword "JNI" & "Android" , most of archives are useless...
BTW, We must install strace, busybox in our emulator and copy system
image to PC? I havn't install it right now.
