我已经阅读了All com.android.support libraries must use the exact same version specification上的线程以及许多其他此类线程,但是没有一个答案能解决我的问题。
错误:-
1。)对于实现'com.android.support:appcompat-v7:26.1.0'
所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃)。找到版本27.1.1、26.1.0。示例包括com.android.support:animated-vector-drawable:27.1.1和com.android.support:cardview-v7:26.1.0以下...(Ctrl + F1) 有一些库,工具或库的组合不兼容或可能导致错误。一种不兼容的情况是使用不是最新版本(或特别是低于targetSdkVersion的版本)的Android支持库版本进行编译。
2。)构建项目
错误:程序类型已存在: android.support.design.widget.CoordinatorLayout $ Behavior

如果要向项目中添加库,最好的方法是:
在android studio中:(从工具栏)文件 \ 项目结构... \(从左侧窗口的模块下) app \ 依赖关系 \ [使用绿色加号]
例如,如果您要使用 compileSdkVersion 27 ,则您的导入代码应如下所示:
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "your project"
minSdkVersion 16
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support:support-v4:27.1.0'
implementation 'com.android.support:design:27.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:support-vector-drawable:27.1.0'
implementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:cardview-v7:27.1.0'
implementation 'com.android.support:recyclerview-v7:27.1.0'
implementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
这对我来说很有效,如果您要使用 compileSdkVersion 28 ,则您的导入代码应如下所示:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "your project"
minSdkVersion 14
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'
}
}
buildToolsVersion '28.0.3'
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'junit:junit:4.12'
implementation 'com.android.support:support-v13:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support.test.espresso:espresso-contrib:3.0.2'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:mediarouter-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'com.android.support:support-annotations:28.0.0'
}
这对我也有用。 在新库的帮助下,许多此类问题将消失,您将拥有更高效的类。
我希望它对您有用。
此版本可以为您提供帮助,我已经对其进行了测试:
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:26.0.0-beta1'
implementation 'com.android.support:support-v4:26.0.0-beta1'
implementation 'com.android.support:design:26.0.0-beta1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:0.5'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
implementation 'com.android.support:gridlayout-v7:26.0.0-beta1'
implementation 'com.android.support:recyclerview-v7:26.0.0-beta1'
implementation 'com.android.support:cardview-v7:26.0.0-beta1'
}

好吧,我终于找到了您的解决方案,只需添加以下行:
repositories {
mavenCentral()
maven { url "https://maven.google.com" }
}
例如:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "your app id"
minSdkVersion 14
targetSdkVersion 26
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 fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:0.5'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
implementation 'com.android.support:gridlayout-v7:26.1.0'
implementation 'com.android.support:recyclerview-v7:26.1.0'
implementation 'com.android.support:cardview-v7:26.1.0'
}
repositories {
mavenCentral()
maven { url "https://maven.google.com" }
}

当您使用使用旧版本AppCompat的库时,通常会发生这种情况。当我使用switchButton库时,这总是发生在我身上。在过去的六个月中,它什么都没有影响,只是一个错误的警报。
