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 23buildToolsVersion "23.0.2"defaultConfig {applicationId "duck.mapdemo"minSdkVersion 9targetSdkVersion 23versionCode 1versionName "1.0"testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"externalNativeBuild {cmake {cppFlags "-frtti -fexceptions"}}}buildTypes {release {minifyEnabled falseproguardFiles 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)}
}
