如何访问Android应用程序的classes.dex？ [英] How to access classes.dex of an Android Application?

问题描述

启动活动时，系统将加载classes.dex文件并开始执行指令。我需要获得对当前活动正在执行的同一应用程序的classes.dex的只读访问权限。

When an activity is launched, the classes.dex file is loaded by the system and start executing the instructions. I need to get readonly access to the classes.dex of the same application under which the current activity is executing.

在网上搜索了几个小时之后，我只能推断出Android安全系统不允许访问应用程序沙箱。

After searching for hours on the net, I could only infer that the Android Security system does not allow access to the application sandbox.

但是，我需要对classes.dex文件具有只读访问权限才能完成任务。

However, i need readonly access to the classes.dex file in order to accomplish my task.

可以有人对此有见识吗？

Does anyone have a insight on this?

提前感谢！

推荐答案

取决于您要执行的操作，但是您可以访问DexFile：

Depends on what you are trying to do, but you can access the DexFile :

String sourceDir = context.getApplicationInfo().sourceDir;
DexFile dexFile = new DexFile(sourceDir);

它为您提供 http://developer.android.com/reference/dalvik/system/DexFile.html 您可以枚举并从中加载类。

it gives you a http://developer.android.com/reference/dalvik/system/DexFile.html which you can enumerate, and load classes from.
