I have a weird error where it says:
java.lang.UnsatisfiedLinkError: dlopen failed: cannot find "./obj/local/armeabi-v7a/libsharedlibrary.so" from verneed[1] in DT_NEEDED list for "/data/data/com.my.app/cache/libnative.so"
I have tried a lot, but I don't understand it. I hope anyone out there can help me! Thanks in advance!
EDIT: It is not a diplicate of this question, as it is not the same error. The answer on that question does not help me...
libsharedlibrary.so is missing its SONAME entry. You probably currently see something like the following:
$ readelf -dW libnative.so | grep NEEDED | grep libsharedlibrary
0x0000000000000001 (NEEDED) Shared library: [./obj/local/armeabi-v7a/libsharedlibrary.so]
Note that if you don't have readelf on your system it is provided in the NDK as $NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-readelf (adjust the path as necessary for your OS). Note that the architecture here doesn't actually matter. readelf is a multi-arch tool. Any toolchain's readelf will work fine.
What you should see if libsharedlibrary.so was built with SONAME is:
$ readelf -dW libnative.so | grep NEEDED | grep libsharedlibrary
0x0000000000000001 (NEEDED) Shared library: [libsharedlibrary.so]
You should see the following on libsharedlibrary.so:
$ readelf -dW libsharedlibrary.so | grep SONAME
0x000000000000000e (SONAME) Library soname: [libsharedlibrary.so]
The problem is that libsharedlibrary.so was not built with the -Wl,-soname,libsharedlibrary.so ldflag. ndk-build and CMake will do that for you, but if you're using a standalone toolchain or a custom build system then you need to provide it yourself.
