android - 错误 :org. gradle.internal.UncheckedException: 构建命令失败

Question

我正在尝试扩展 this project ，但它是使用 ANT 构建的，这些天我们在实践中使用 Android Studio 和 Gradle。我想将它移动到 Android Studio 上以进一步实现。所以这是我的项目结构...

app/build.gradle

apply plugin: 'com.android.application'
android {
    compileSdkVersion 25
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "tum.andrive"

        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi", "armeabi-v7a"
        }
        sourceSets {
            main {
                jniLibs.srcDirs = ['src/main/cpp']
            }
        }
        externalNativeBuild {
            cmake {
                cppFlags "-frtti -fexceptions"
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile project(':opencv')

但是在构建项目时出错，看看这个...

任何人请帮助我设置这个项目!

Answer 1

经过大量搜索，我找到了 this项目。非常感谢Adrien Lescourt .此演示项目描述了我们如何将 OpenCV 与 Android Studio 和 Gradle 结合使用。问题出在 jniLibs 目录和 CMakeLists.txt 文件上。这是正确的版本...

app/build.gradle

apply plugin: 'com.android.application'
android {
    compileSdkVersion 25
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "tum.andrive"
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a"
        }
        sourceSets {
            main {
                jniLibs.srcDirs = ['src/main/jniLibs']
            }
        }
        externalNativeBuild {
            cmake {
                cppFlags "-frtti -fexceptions"
                abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'arm64-v8a', 'mips', 'mips64'
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile project(':opencv')
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.4.1)

# OpenCV stuff
include_directories(D:\\Android\\OpenCV-2.4.10-android-sdk\\sdk\\native\\jni\\include)
add_library( lib_opencv SHARED IMPORTED )
set_target_properties(lib_opencv PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/src/main/jniLibs/${ANDROID_ABI}/libopencv_java.so)

add_library( native-lib             
             SHARED                          
             src/main/cpp/native-lib.cpp )

find_library( log-lib
              log )

target_link_libraries( native-lib                       
                       lib_opencv
                       ${log-lib} )

最后，我将 jniLibs 文件夹添加到应用程序并将所有 .so 文件复制到存储在 OpenCV-2.4.10-android-sdk/sdk/native/libs 中的该文件夹中.

我希望这个解决方案能帮助人们使用 gradle 设置 OpenCV。如果需要任何其他信息，请发表评论。

谢谢
