java.lang.UnsatisfiedLinkError:dlopen失败: [英] java.lang.UnsatisfiedLinkError: dlopen failed:

问题描述

在我将.so文件添加到项目中时，我正面临另一个问题，我尝试了不同的解决方案，但没有任何解决方案可以帮助我.

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.

情况:1 我试图将.so放入src/main/jniLibs和gradle文件中，我在下面几行中添加了内容，但出现相同的错误.

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 = []
}

情况:2 我已经使用native-lib.cpp添加了cpp文件夹，并在gradle中添加了以下代码:

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"
  }
   }

情况:3 我创建了一个新的具有c/c ++支持的新项目，并在cpp文件夹下的gradle中添加了一个.so文件:

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"

        }
    }
}

我正在使用android studio 3.0.1，gradle:3.0.1

I am using android studio 3.0.1, gradle: 3.0.1

推荐答案

尝试将其添加到build.gradle:

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

或在android块中添加以下内容:

or add following into android block:

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

读取默认的jniLibs路径时，Gradle可能会出现问题，只需使其隐式即可.

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

sourceSets.main.jni.srcDirs不起作用，因为它定义了jni source，例如cpp源文件文件夹.

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

异常堆栈 nativeLibraryDirectories = [/vendor/lib，/system/lib]]] 显示系统根本没有检测到您的lib.要进行验证，请精确检查您的apk，以查看是否有/lib文件夹和您的*.so.

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.
