摘要： http://bbs.pediy.com/showthread.php?t=129004最快的学习,莫过于对着代码找,那么,从google上下载了os_monitor的apk和源代码 把apk改zip解压,然后到\lib\armeabi找到libosmonitor.so,用IDA打开呗. 打开源代码的jni文件夹,随便找一个函数,我找的是JNI_OnUnload:void JNI_OnUnload(JavaVM* vm, void* reserved){ JNIEnv *env; jclass cls; if ((*vm)->GetEnv(vm, (void **) &env, 阅读全文

摘要： http://blog.claudxiao.net/2012/01/smali_syntax_for_latex/smali是对Dalvik虚拟机指令集的一种汇编语法，基于jasmin语法修改而来。在LaTeX中引用代码，一般使用listings宏包，最后一定修订于1999年的listings显然不会支持smali高亮，所以我写了这样一个文件，下载地址：http://code.google.com/p/amatutor/source/browse/smali.sty效果如下：其中关键词和配色方案参考了lohan+在其博客http://androidcracking.blogspot.com中提 阅读全文

摘要： Service的生命周期方法比Activity少一些，只有onCreate, onStart, onDestroy我们有两种方式启动一个Service,他们对Service生命周期的影响是不一样的。1 通过startService Service会经历 onCreate --> onStart stopService的时候直接onDestroy 如果是 调用者 直接退出而没有调用stopService的话，Service会一直在后台运行。 下次调用者再起来仍然可以stopService。2 通过bindService Service只会运行onCreate， 这个时候 调用者和Servi 阅读全文

摘要： http://blog.claudxiao.net/2011/12/arm-disassemblers/最近在为androguard实现ARM反汇编和ARM漏洞利用代码检测的功能。Anthony告诉我三种方案：smiasm、radare、IDAPython。前段时间尝试了这些方法，各有优劣。归纳如下：方案开源支持Thumb递归反汇编提供指令详情smiasm是否是是radare是是否否IDAPython否是是是下面是详细情况：smiasmsmiasm是一个纯Python的反汇编框架。它由三个子项目构成，其中elfesteem实现ELF和PE格式解析，miasm实现反汇编。smiasm的代码使用了 阅读全文

摘要： http://blog.csdn.net/fontlose/article/details/6686161assets目录底下的文件会被打包到一个apk文件里，这些资源在安装时他们并没被解压,使用时是直接从apk中读取的。这里介绍下怎么在jni内使用 ndk自带api的接口函数读取assets资源文件，和libzip库函数的使用，可以用来读创建修改压缩文档，这里也是以读取apk安装包内的资源文 件为例。1 用ndk自带的接口函数读apk包，从2.3开始提供这些接口函数，具体看头文件assert.h android/asset_manager.h android/asset_manager_jn 阅读全文
