java.lang.UnsatisfiedLinkError: dlopen failed:

Question

I am facing the issue while I am adding the .so file in my project, from the other ans, I have tried with different solutions but not any solution help me out.

case: 1 I had tried to put my .so in src/main/jniLibs and in the gradle file I had added below lines, but getting the same error.

 android { sourceSets.main.jni.srcDirs = [] }

case:2 I had added cpp folder with native-lib.cpp and in gradle added below code:

defaultConfig { ndk { abiFilters "armeabi", "armeabi-v7a", "x86", "mips" } }

case:3 I had created new fresh project with c/c++ support and add a .so file under cpp folder and in the gradle added below code:

defaultConfig { externalNativeBuild { cmake { cppFlags "-std=c++11" } } }

My project architecture

error code:

I am using android studio 3.0.1, gradle: 3.0.1

To which library you are getting this error and which architecture your getting this error, this information helps to answer. — Raviprakash

I have edited my question, I had added the image. I am trying to add the .so file in armeabi and armeabi-v7a. — Khyati Chitroda

If you are copying manually then it is not right, the library binary file for each architecture is different. — Raviprakash

Please upload the whole UnsatisfiedLinkError: dlopen failed log. There are many info in the end message indicated what happened actually. — sakiM

Try add this in build.gradle:

sourceSets.main.jniLibs.srcDirs = ['src/main/jniLibs']

or add following into android block:

sourceSets { main { jniLibs.srcDirs = ['src/main/jniLibs'] } }

Gradle may have problem when read default jniLibs path, just make it implicit.

sourceSets.main.jni.srcDirs not work because it defines jni source, like cpp source files folder.

Exception stacks nativeLibraryDirectories=[/vendor/lib, /system/lib]]] shows that system didn't detect your lib at all. To verify it, exact your apk to see whether there is a /lib folder and your *.so.

@KhyatiChitroda Notice that this is jniLibs.srcDirs, nor jni.srcDirs. Have you unzip your apk to see whether there are so files in /lib?
@KhyatiChitroda It may be in a wrong path because sourceSet starts on module folder... Answer updated.
You could accept the answer and vote up if it solves your problem really. :)

-1

Or make your main library a SHARED library.

add_library(libname SHARED //files.cpp )
