如何在AAR文件中的共享库中使用ndk-stack [英] How to use ndk-stack with shared library in AAR file

问题描述

我在Android应用程序中使用共享库.这些共享库在.aar文件中.

I'm using shared object libraries in Android application. These shared object libraries are in .aar file.

一个库崩溃了.为了检查崩溃日志和确切的行号.我正在用ndk-stack接过.

One of library is crashing. In order to check crash logs and exact line no. I am using ndk-stack took.

ndk-stack的用法是

$ adb logcat |  ndk-stack -sym <Path to  your shared libraries>

现在如何在AAR文件中获取共享库的路径?

Now How can I get a path of shared libraries in AAR file?

推荐答案

您应该记住，并非每个.so文件都对ndk-stack有用. Android NDK生成两种.so文件:已剥离和未剥离.最大的不同是，最后一个包含调试信息，而ndk-stack则需要，而第一个则不需要. readelf可能有助于检查是否删除了特定文件:

You should keep in mind that not every .so file is useful for ndk-stack. Android NDK produces two kinds of .so files: stripped and non-stripped. The most difference is that last ones contain debug information, that is needed for ndk-stack and first ones don't. readelf may help to check if particular file is stripped or not:

$ readelf <non-stripped-lib> -S | grep debug
  [23] .debug_info       PROGBITS        00000000 00302c 0052d9 00      0   0  1
  [24] .debug_abbrev     PROGBITS        00000000 008305 000879 00      0   0  1
  [25] .debug_loc        PROGBITS        00000000 008b7e 001aa7 00      0   0  1
  [26] .debug_aranges    PROGBITS        00000000 00a628 000088 00      0   0  8
  [27] .debug_ranges     PROGBITS        00000000 00a6b0 0000d0 00      0   0  1
  [28] .debug_line       PROGBITS        00000000 00a780 0009de 00      0   0  1
  [29] .debug_str        PROGBITS        00000000 00b15e 002387 01  MS  0   0  1
  [30] .debug_frame      PROGBITS        00000000 00d4e8 0003d0 00      0   0  4
$

$ readelf <stripped-lib> -S | grep debug
$ 

如您所见，未剥离的ELF有很多.debug_*部分，的确包含行号，私有/静态函数名称等.

As you see not-stripped ELF has a lot of .debug_* sections, that indeed contain line numbers, private / static function names, etc.

接下来，.aar个文件(包括调试文件和发布文件)仅具有 stripped 二进制文件.因此它们对于ndk-stack毫无用处.

Next, .aar files, both debug and release ones, has only stripped binaries. So they are useless for ndk-stack.

AFAIK，唯一可以找到未剥离二进制文件的位置是obj/目录.它的位置在某种程度上取决于所使用的构建系统:

AFAIK, the only place where non-stripped binaries may be found is a obj/ dir. Its location depends slightly on used build system:

• 对于ndk-build，它位于<module_name>/build/intermediates/ndk
下 对于基于CMake的
• 位于<module_name>/build/intermediates/cmake
下

• for ndk-build it is under <module_name>/build/intermediates/ndk
• for CMake-based it is under <module_name>/build/intermediates/cmake

另外，似乎开箱即用的android gradle插件无法将未剥离的库打包到您的aar中，因此，唯一的方法是在build.gradle中执行一些自定义任务.

Also it looks like out-of-the-box android gradle plugin offers no way to pack unstripped libraries to your aar, so the only way here is some custom task in your build.gradle.
