解决方案：ThelibraryyouaretryingtoloadwasmostlikelybuiltwithWl,hash-style=gnu.ThiswasnotsupportedonAndroiduntilrecently(afaikthisisn’teveninL).Youneedtobuildyourlibrarieswith-Wl,-hash-style=sysv.Howdidyoubuildcpplibrary.so?Ifyoudidn’tdoanythingtomanuallyswitchtothegnuhashstyle,itcouldbeabugintheNDK.
One option is to add "LOCAL_LDFLAGS := -Wl,–hash-style=sysv" at screenrecord Android.mk though I am sure there is a less hacky method of doing so..
总结了一下是需要在Android.mk中添加链接选项：
LOCAL_LDFLAGS := Wl,-hash-style=sysv
libsysv-hash-table-library_ldflags := Wl,-hash-style=sysv
于是在修改前后查看了一下so节的变化：

修改前后的节并没有什么变化，，然并卵啊！
