 ====== Android JNI相关 ======
 收集一些Android JNI的使用方法。
+====== JNA ======
+<code>
+JNA provides Java programs easy access to native shared libraries without writing anything but Java code - no JNI or native code is required. This functionality is comparable to Windows' Platform/Invoke and Python's ctypes.
+JNA allows you to call directly into native functions using natural Java method invocation. The Java call looks just like the call does in native code. Most calls require no special handling or configuration; no boilerplate or generated code is required.

-android-ndk-stacktrace-analyzer用法
-<code>
-android-ndk/android-ndk-1.6_r1/build/prebuilt/linux-x86/arm-eabi-4.2.1/bin/arm-eabi-objdump -S mylib.so > mylib.asm
-python parse_stack.py mylib.asm logcat.txt
-</code>
-stack用法:
-<code>
-python stack.py logcat.txt
-</code>
-说明:stack看起来是google内部使用的工具，在windows上跑不起来，需要在Linux环境下，还有使用的时候会提示so文件的位置不存在，按照它的要求，建立相应的目录，并放入so文件就可以了。
