无法解决：com.android.support:appcompat-v7:28.+，错误：多个库的包名称为“android.support.graphics.drawable”

Question

我是 Android Studio 的新手，我尝试了一切来解决这个问题“无法解决：com.android.support:appcompat-v7:28.+”

我尝试清理项目，使现金/重启无效并删除 .idea，但还是一样

出于学习原因，我正在使用 android studio 2.2.1，我将其更新为 android studio 3，但出现多个渲染问题，因此我返回到 2.2.1 版本

我尝试添加

行家{
网址'https://maven.google.com/' 名称“谷歌” }

所以，它遇到了另一个问题

"Error:Execution failed for task ':app:processDebugResources'.
> Error: more than one library with package name 'android.support.graphics.drawable'"

Error Photo

最后我尝试将“appcompat-v7:28.+”更改为“appcompat-v7:27”并且它有效但仍然告诉我应该使用相同的库以避免错误

这是我的 Gradle 代码：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.1"
    defaultConfig {
        applicationId "com.example.aimlive.myapplication"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:28.+'
    testCompile 'junit:junit:4.12'
}

Answer 1

将'com.android.support:appcompat-v7:28+' 替换为'com.android.support:appcompat-v7:28.0.0'

并在下面添加依赖项

implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'

Answer 2

尝试将此添加到您的代码中：

repositories {
    jcenter()
    maven {                                  // <-- Add this
        url 'https://maven.google.com/'
    }
}

更新：现在你又犯了另一个错误：

错误：多个库的包名称为 'android.support.graphics.drawable ...

要解决此问题，您需要将 dependencies 部分中的 compile 更改为 implementation。

Answer 3

如果你正在使用

    compileSdkVersion 28

在代码下方添加你的依赖项

    implementation 'com.android.support:appcompat-v7:28.0.0-alpha'

这是link

Answer 4

试试这个，希望它有效

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

依赖

  classpath 'com.android.tools.build:gradle:3.1.4'

安卓

  compileSdkVersion 28
  minSdkVersion 21
  targetSdkVersion 28

Answer 5

试试这个代码，希望它能工作。谢谢

build.gradle（项目）

 dependencies {
    classpath 'com.android.tools.build:gradle:3.1.4'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

build.gradle（应用程序）

android {
compileSdkVersion 28
buildToolsVersion '28.0.3'

defaultConfig {
    applicationId "YOUR_PACKAGE_NAME"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    renderscriptTargetApi 19
    renderscriptSupportModeEnabled true

    // Enabling multidex support.
    multiDexEnabled true
}

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

lintOptions {
    abortOnError false
}

}

依赖项检查实现

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

}

Answer 6

我发现 'com.android.support:animated-vector-drawable' 和 'com.android.support:support-vector-drawable' 在支持库版本 28.0.0 中具有相同的包名称。通常这不会造成问题。

但如果你在 gradle.properties 中有以下行

android.uniquePackageNames = true

你会看到错误

more than one library with package name 'android.support.graphics.drawable'"

如果您应该使用 uniquePackageNames 选项，请使用 androidx 而不是支持库 28.0.0。

Answer 7

        In case someone like me stuck for hours and find out the you have to check the maven dependency "com.android.support:appcompat-v7:28.0.0". remove the "+" sign as gradle does not like it for unpredictable versions. so i had to check the maven repository and found that i was compiling with 29 and 29 does not exist. please check below link
[""][1]

        apply plugin: 'com.android.application'

        android {
            compileSdkVersion 28
            defaultConfig {
                applicationId "com.example.amirkhan.birthday"
                minSdkVersion 15
                targetSdkVersion 28
                versionCode 1
                versionName "1.0"
                testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
            }
            buildTypes {
                release {
                    minifyEnabled false
                    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
                }
            }
        }

        dependencies {

            implementation 'com.android.support:appcompat-v7:28.0.0'

        }

    2)) Maven should be included.
    allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
            google()
        }
    }


    Wallah the problem is solved
