高德地图报Native method not found: com.autonavi.amap.mapcore.MapCore.nativeNewInstance:

在集成高德地图demo时候遇到一个奇怪的问题，我是按照官网上的demo完全集成的， 却死活加载不出地图详情，并且抛出如下异常；

百度发现一哥门也跟我遇到同样的问题，他的解决办法是:

对比了一下高德提供的demo 发现少了x86的文件夹，将x86文件夹粘贴到lib目录下运行就好了

可是我在官网提供的demo上死活找不到X86文件夹~~~于是尴尬症又犯了~~只好接着找

果然功夫不负有心人，还真被我找到了这篇文章点击查看 ，错误原因是SO文件导入错了

正确的解决办法是：打开在APP下的build.gradle文件，在android下加入

   task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") {        destinationDir file("$projectDir/libs")        baseName "Native_Libs2"        extension "jar"        from fileTree(dir: "libs", include: "**/*.so")        into "lib"    }    tasks.withType(JavaCompile) {        compileTask -> compileTask.dependsOn(nativeLibsToJar)    }

完整的build.gradle文件如下：

android {    compileSdkVersion 23    buildToolsVersion "23.0.2"    defaultConfig {        applicationId "duck.mapdemo"        minSdkVersion 9        targetSdkVersion 23        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"        externalNativeBuild {            cmake {                cppFlags "-frtti -fexceptions"            }        }    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    externalNativeBuild {        cmake {            path "CMakeLists.txt"        }    }    task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") {        destinationDir file("$projectDir/libs")        baseName "Native_Libs2"        extension "jar"        from fileTree(dir: "libs", include: "**/*.so")        into "lib"    }    tasks.withType(JavaCompile) {        compileTask -> compileTask.dependsOn(nativeLibsToJar)    }}
