【问题描述】:
我是 android studio 的新手,我正在尝试学习 firebase 并在我的虚拟应用程序中实现 google 登录。
我继续按照谷歌的文档在 build.gradle 文件中包含某些行
在我添加的项目/gradle
classpath 'com.google.gms:google-services:4.3.3'
在 app/gradle 我检查了apply plugin: 'com.android.application' 和
apply plugin: 'com.google.gms.google-services'
因为它已经存在,我补充说:
implementation 'com.google.firebase:firebase-analytics:17.2.2'
我同步了我的项目,当我尝试运行应用程序时,我收到以下错误:
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 <application> element at AndroidManifest.xml:5:5-19:19 to override.
请告诉我我做错了什么? 我在 Windows 10 上使用 android studio
编辑:这是用户建议的我的清单 xml 文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.MyName.TestApp">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
我的应用程序 gradle 文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.MyName.TestApp"
minSdkVersion 23
targetSdkVersion 28
versionCode 1

implementation 'com.google.firebase:firebase-analytics:17.2.3'
}
apply plugin: 'com.google.gms.google-services'
打包 gradle 文件
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3.1'
classpath 'com.google.gms:google-services:4.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
【问题讨论】:
-
您的问题出在您的 AndroidManifest.xml 中,错误提示在您的 Manifest 的应用程序标签中添加
tools:replace="android:appComponentFactory",这是因为重复尝试添加您的 Manifest,以便有人可以提供更好的帮助跨度>
