从SD卡动态加载共享库
[英]Dynamically load shared library from sd card
问题描述
I want to dynamically load library from SD card, with dlopen, but when I do it, get error: dlopen failed: couldn't map "/storage/emulated/0/Documents/Tests/armeabi-v7a/libtest.so" segment 2: Operation not permitted 
我想使用dlopen从SD卡动态加载库，但执行此操作时出现错误：dlopen失败：无法映射“ /storage/emulated/0/Documents/Tests/armeabi-v7a/libtest.so”段2：不允许操作
When i use it for internal storage it's work. 当我将其用于内部存储时，它可以工作。 What can i do to solve this problem? 我该怎么做才能解决这个问题？

This is disallowed by Android's security policy. Android的安全策略不允许这样做。 Anyone can write to that location, so loading code from it is an easily exploitable attack vector. 任何人都可以写入该位置，因此从该位置加载代码是容易利用的攻击媒介。
