9、使用Android ndk-stack tool --可参考

1)、adb logcat -v threadtime 先使用此命令设置logcat，具体含义，待查。

2)、然后把出错信息从ecplise中拷到一个文件如foo.txt，注意：

The tool looksfor the initial line containing starts in the logcat output,i.e. somethingthat looks like:

*** *** *** *** *** *** *** *** *** ****** *** *** *** *** ***

When copy/pastingtraces,don't forget this line from the traces,or ndk-stack won't workcorrectly.

3)、然后把文件放入cygwin64\tmp目录下

4）、 在cygwin中命令：

ndk-stack-sym cygdrive/e/project/trunk/client/Project/XXKaPai/proj.android/obj/local/armeabi-dump foo.txt

（$NDK/ndk-stack -sym $PROJECT_PATH/obj/local/armeabi -dump foo.txt）

注：此操作也可以在dos命令下操作

在cygwin下操作，必须要进入/tmp 目录。

在window下，直接拖动文件到dos命令行

10、javac命令使用：

例子：

E:\project\trunk\client\Project\XXKaPai\proj.android>javac-cp E:\project\trunk\client\Project\XXKaP

ai\proj.android\src;E:\soft\adt-bundle-windows\sdk\platforms\android-8\android.jar -encoding utf8 -

d . E:\project\trunk\client\Project\XXKaPai\proj.android\src\com\zhi\util\StringUtil.java

11、JNI

1、In theory you can have multiple JavaVMs perprocess,but Android only allows one.

12、LOCAL_LDLIBS isalways ignored for static libraries

You're right. LOCAL_STATIC_LIBRARIES is agood way to import the module you need in your project.
BTW,as far as I know,LOCAL_LDLIBS is OK when current .mk is made for sharedlibrary.You'll find that in .mk like this

include$(BUILD_SHARED_LIBRARY)

But not for astatic library as it shown

LOCAL_LDLIBS isalways ignored for static libraries
