链接Android NDK中的版本化共享库

我试图通过loadLibrary调用在我的 Android应用程序中加载两个共享库：

System.loadLibrary("mywrapper");
System.loadLibrary("crypto");

我一直在追赶’UnsatisfiedLinkError’.这是错误的更详细版本.

Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1969]:
  130 Could not load needed library 'libcrypto.so.1.0.0' for 
  'libmywrapper.so' (load_library[1111]: Library 'libcrypto.so.1.0.0' not found)

有任何想法吗？

花了一些时间后,我发现Android不支持版本化库.有谁遇到过同样的问题？

解决方法

我在为Android构建libwebsockets时遇到了同样的问题,需要与OpenSSL链接.我以libssl.so为例.您应该对相关的.so 文件执行相同的操作.

Before:
huiying@huiying-PORTEGE-R835:~$objdump -p libssl.so | grep so
libssl.so:     file format elf32-little
  NEEDED               libcrypto.so.1.0.0
  NEEDED               libdl.so
  NEEDED               libc.so
  SONAME               libssl.so.1.0.0

After 
huiying@huiying-PORTEGE-R835:~$rpl -R -e .so.1.0.0 "_1_0_0.so" libssl.so 
Replacing ".so.1.0.0" with "_1_0_0.so" (case sensitive) (partial words matched)
.
A Total of 2 matches replaced in 1 file searched.
huiying@huiying-PORTEGE-R835:~$objdump -p libssl.so | grep so
libssl.so:     file format elf32-little
  NEEDED               libcrypto_1_0_0.so
  NEEDED               libdl.so
  NEEDED               libc.so
  SONAME               libssl_1_0_0.so

And don't forget to change file name "libssl.so" to "libssl_1_0_0.so".

黑客工作.我已经运行Android应用来证明这一点.在http://computervisionandjava.blogspot.com/2015/05/trouble-with-versioned-shared-libraries.html看到我的咆哮.
