android上存储的所有共享库在哪里？

Question

所有共享库 (.so) 存储在 Android 上的什么位置？我能够找到 /system/lib 目录，但我确信还有更多。无法使用 find 命令也无济于事。

Answer 1

在我分析的许多 AOSP 和供应商图像中，我观察到共享库的常规位置模式，如下所示（其中一些仅在较新版本中）：

• system/app/<name>/lib/<arch>
• system/priv-app/<name>/lib/<arch>
• system/lib
• system/lib64
• system/vendor/lib
• system/vendor/lib64

我偶尔也会看到非标准位置，例如运行 Android 5.1.1 的 Samsung Edge 上的system/csc/common/system/lib64/。

要查找特定设备上所有共享库的位置，最好的办法是使用find / -name \*.so 以root 身份递归搜索整个设备文件系统。如果您无法安装 find（通过 Busybox 等），您可以尝试提取系统映像，将其安装在 Linux 系统上并在已​​安装的文件系统上运行 find。

Answer 2

adb shell 'find / -iname "*.so" 2>/dev/null'

跑得惊人的快。

Answer 3

这是我的模拟器上 API 级别 23 的所有 .so 文件。请注意，这些是设备的实现细节，不保证在任何时候都保持不变。

这些都在/system下。
