Question

我在github https://github.com/joaopedronardari/OpenCV-AndroidSamples中克隆项目时遇到问题，并且出错。我不知道该项目可能已过期或发生了什么。但它是3年前上传的。请协助解决我的问题，感谢所有回答我问题的人（回答并修正我的说法）这是gradle

构建gradle（应用程序）：

apply plugin: 'com.android.application'

model {

android {
    compileSdkVersion = 22
    buildToolsVersion = "23.0.0"

    defaultConfig.with {
        applicationId = "com.jnardari.opencv_androidsamples"
        minSdkVersion.apiLevel = 10
        targetSdkVersion.apiLevel = 22
        versionCode = 1
        versionName = "1.0"
    }
}

android.buildTypes {
    release {
        minifyEnabled = false
        proguardFiles += file('proguard-rules.pro')
    }
}

/*
 * native build settings
 */
android.ndk {
    moduleName = "ndklibrarysample"
    cppFlags += ["-std=c++11", "-fexceptions", "-frtti"]
    cppFlags  += "-I${file("C:/Users/jnardari/Desktop/OpenCV-android-sdk/sdk/native/jni/include")}".toString()
    ldLibs += ["android", "EGL", "GLESv2", "dl", "log", "z"]
    stl = "gnustl_static"
}

android.productFlavors {
    create("arm") {
        ndk.with {
            abiFilters += "armeabi"

            File curDir = file('./')
            curDir = file(curDir.absolutePath)
            String libsDir = curDir.absolutePath + "\\src\\main\\jniLibs\\armeabi\\"

            ldLibs += libsDir + "libopencv_java3.so"
        }
    }
    create("armv7") {
        ndk.with {
            abiFilters += "armeabi-v7a"

            File curDir = file('./')
            curDir = file(curDir.absolutePath)
            String libsDir = curDir.absolutePath + "\\src\\main\\jniLibs\\armeabi-v7a\\"

            ldLibs += libsDir + "libopencv_java3.so"
        }
    }
    create("x86") {
        ndk.with {
            abiFilters += "x86"

            File curDir = file('./')
            curDir = file(curDir.absolutePath)
            String libsDir = curDir.absolutePath + "\\src\\main\\jniLibs\\x86\\"

            ldLibs += libsDir + "libopencv_java3.so"
        }
    }
    create("mips") {
        ndk.with {
            abiFilters += "mips"

            File curDir = file('./')
            curDir = file(curDir.absolutePath)
            String libsDir = curDir.absolutePath + "\\src\\main\\jniLibs\\mips\\"

            ldLibs += libsDir + "libopencv_java3.so"
        }
    }
    create("fat") {

    }
}
}

dependencies {

    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile project(':libraries:opencv')
}

构建gradle（项目）：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
    jcenter()
    mavenCentral()
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.3'
}

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}


allprojects {
repositories {
    jcenter()
}
}

这是gradle-wrapper：

distributionPath=wrapper/dists

Answer 1

进行以下代码更改：

compileSdkVersion 27
minSdkVersion 19
targetSdkVersion 27
implementation 'com.android.support:appcompat-v7:27.1.1'

还有另一件事，您正在尝试在Android Studio 3.0中打开与Android Studio 2.0中开发的项目相同的项目。而不是打开项目。尝试导入项目。我不确定android studio的迁移，但肯定会造成问题。我没有任何相关文章，但尝试找出一些问题。

Answer 2

嗯...这个项目似乎已经过时，要么要求维护者更新该项目，要么找到另一个项目。我不是gradle的专家，但是我知道您会浪费时间来修复gradle文件。

编辑：我尝试了@Mbuodile Obiosio的解决方案，但是没有用。

错误：原因：未指定compileSdkVersion
