so库打包成功，最后运行报错：Build command failed. about ffmpegaudioplayer

[lxq666]

对了我的CmakeLists.txt在app/src/main/cpp的文件夹下面，但是我把这个文件挪到app/下面，结果报了更多的错误：

看下app/bulid.gradle的配置,你对比一下

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "io.github.iamyours.ffmpegaudioplayer"
        minSdkVersion 14
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++11"
            }
            ndk{
                abiFilters "armeabi", "x86","x86_64"
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

我的build.gradle文件：

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.ffmpegdemo"
        minSdkVersion 14
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++11"
            }
            ndk{
                abiFilters "armeabi"
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            version "3.6.0"
        }
    }
}

abiFilters改成： "armeabi", "x86","x86_64"
注释version:"3.6.0"
还是报原来的错误。

[iamyours]

CMakeLists.txt放到app目录下，里面的配置是以app为根目录的

[lxq666]

报了这样的错：

你先试试用我这边到so文件编译，看看是不是so文件有问题

[lxq666]

确实是so库的问题，可能是我项目中使用的ndk版本和bash_profile中配置的版本不同导致的。我又重新编译了一遍so库，可以运行了。
