项目中添加.jar文件的问题

Question

添加了两个自定义 zxing 和 zbar 库，用于通过文件>新建>读取和生成条形码 Jar.file 添加它们之后在项目结构中也添加了它们并在所有已经打开的问题中选择了实现使用编译但在 android studio 它不再代替它实现 api 如何正确添加它们？

build.gradle（应用程序）

apply plugin: 'com.android.application'
check.dependsOn 'assembleDebugAndroidTest'

android {
compileSdkVersion 28
flavorDimensions "minSdkVersion"

defaultConfig {

    minSdkVersion 16
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
'android.support.test.runner.AndroidJUnitRunner'
}

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 
'proguard-rules.pro'
    }
}

compileOptions {
    sourceCompatibility 1.8
    targetCompatibility 1.8
}
}

configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:28.0.0'
}

dependencies {
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'

implementation project(':zbar')
implementation project(':zxing_core')
}

apply plugin: 'com.google.gms.google-services'

build.gradle（项目）

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

buildscript {
repositories {
    jcenter()
    mavenLocal()
    google()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.3.2'
    classpath 'com.google.gms:google-services:4.2.0'
}
  }

allprojects {
repositories {
    mavenLocal()
    jcenter()
    google()
    maven { url 'https://maven.fabric.io/public' }
}
  }

  task clean(type: Delete) {
delete rootProject.buildDir
 }

Answer 1

我建议使用此处 https://mvnrepository.com/artifact/com.google.zxing 的依赖项，但在您的情况下（只要您要添加 jar），您可以通过 implementation fileTree(include: ['*.jar'], dir: 'libs') 在 [=14= 中插入它们]（库将替换为它们进入的任何文件夹）。
