NDK:如何在 AndroidStudio 中包含 *.so 文件 [英] NDK: how include *.so files in AndroidStudio

问题描述

我有 libs jar 和 *.so.我在教程中创建了 Eclipse 项目(对于这个库).我现在在 Android Studio 中做项目，但系统找不到 *.so 文件.我如何在这个 - 在 android studio 的 apk 中包含 .so 库 .我的应用程序在 so libs 中找不到函数.如何找到它们?日志:

I have libs jar and *.so. I created Eclipse project as in tutorial (for this libs). I am now doing project in Android Studio, but system can't find *.so files. I make how in this - Include .so library in apk in android studio . My app does not find function in so libs. How to find them? Log:

使用 JAR 库创建对象时发生错误.她反过来戳 *.so 文件，但要找到她需要的东西.谁应该受到指责，该怎么做?

An error occurs when creating an object using a JAR library. She in turn poked *.so files, but to find what she needs. Who is to blame and what to do?

推荐答案

三个选项:

一个

将您的 *.SO 库复制到您的 libs 文件夹中并将其放在 Build.gradle 上:

Copy yours *.SO libraries on your libs folder and put that on Build.gradle:

dependencies
        {
    compile fileTree(include: ['*.jar'], dir: 'libs')
}

两个

在 src/main/jniLibs 上创建一个新文件夹并将其写入您的 Build.gradle:

Make a new folder on src/main/jniLibs and write that on your Build.gradle:

android {
    //Another code 
    sourceSets {
        main {         
            jniLibs.srcDirs = ['src/main/jnilibs']          
        }
        //Another code 
    }//sourceSets tag close
}//Android tag close

那里

在 src/main/jniLibs 上创建一个新文件夹并将其写入您的 Build.gradle:

Make a new folder on src/main/jniLibs and write that on your Build.gradle:

//Another code....

    dependencies
    {
          compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')
    }//end dependencies


    task nativeLibsToJar(type: Jar, description: 'create a jar archive of the native libs') {
        destinationDir file("$buildDir/native-libs")
        baseName 'native-libs'
        from fileTree(dir: 'src/main/jnilibs', include: '**/*.so')
        into 'lib/'
    }

    tasks.withType(JavaCompile)
     {
          compileTask -> compileTask.dependsOn(nativeLibsToJar)
     }
