java - list 合并失败 : Attribute application@appComponentFactory updating Firebase libraries

Question

我正在尝试在我的项目中添加 Firebase，但是当我实现 'com.google.firebase:firebase-messaging:19.0.0'和 'com.google.firebase:firebase-core:17.0.0' .
build.gradle (这里是错误)

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

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

 dexOptions {
    javaMaxHeapSize "2g"
 }
}

dependencies {
 implementation 'com.roughike:bottom-bar:2.0'
 implementation 'com.android.support:support-v4:28.0.0'
 implementation 'com.android.support:exifinterface:28.0.0'
 implementation 'com.android.support:animated-vector-drawable:28.0.0'
 implementation 'com.flaviofaria:kenburnsview:1.0.7'
 implementation fileTree(include: ['*.jar'], dir: 'libs')
 implementation 'com.android.support:appcompat-v7:28.0.0'
 implementation 'com.android.support.constraint:constraint-layout:1.1.3'
 implementation 'com.android.support:design:28.0.0'
 implementation 'com.github.chrisbanes:PhotoView:2.1.4'
 implementation 'com.google.firebase:firebase-messaging:19.0.0'
 implementation 'com.google.firebase:firebase-core:17.0.0'
 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'
 implementation 'com.android.support:recyclerview-v7:28.0.0'
 implementation 'com.android.support:cardview-v7:28.0.0'
 implementation "com.google.android.gms:play-services-location:17.0.0"
 implementation 'com.google.android.gms:play-services-maps:17.0.0'
 implementation 'com.google.android.gms:play-services-base:17.0.0'
 implementation 'com.github.ahmedshaban1:EasySlider:1.0.0'
 implementation 'com.liangfeizc:SlidePageIndicator:1.1.0@aar'
 implementation 'me.relex:circleindicator:1.2.2@aar'
 implementation 'com.github.bumptech.glide:glide:4.8.0'
 annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'

}

另一个gradle文件:

buildscript {

 repositories {
    google()
    jcenter()
 }
 dependencies {
    classpath 'com.android.tools.build:gradle:3.4.1'
    classpath 'com.google.gms:google-services:4.2.0'


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

  allprojects {
    repositories {
     google()
     mavenCentral()
     jcenter()
     maven {
        url "https://maven.google.com"
        }
     maven { url "https://jitpack.io" }
   }
  }

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

显示关于 com.android.support:support-v4:28.0.0 的错误:

Dependencies using groupId com.android.support and androidx.* can not be combined but found IdeMavenCoordinates{myGroupId='com.android.support', myArtifactId='cardview-v7', myVersion='28.0.0', myPacking='aar', myClassifier='null'} and IdeMavenCoordinates{myGroupId='androidx.coordinatorlayout', myArtifactId='coordinatorlayout', myVersion='1.0.0', myPacking='aar', myClassifier='null'} incompatible dependencies

Inspection info:There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion).

还有当我构建 apk 时，它显示此错误:

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:13:5-354:19 to override.

adding tools:replace="android:appComponentFactory" doesn't work though

Answer 1

在新版本中，库从 Android 支持库迁移到 Jetpack (AndroidX) 库。

除非您在应用程序中进行以下更改，否则更新的库将不起作用:

将 com.android.tools.build:gradle 升级到 v3.2.1 或更高版本。

将 compileSdkVersion 升级到 28 或更高版本。

更新您的应用以使用 Jetpack (AndroidX)；按照 Migrating to AndroidX 中的说明进行操作.

方法一:

在你的 gradle.properties 文件中添加这两个，而不更新任何东西

android.useAndroidX=true
android.enableJetifier=true

方法二

如果 Method-1 不能解决您的问题
做一件事
如果您使用的是 android studio 3.2 或更高版本
转至重构>迁移到 AndroidX...
