构建gradle时出错 - com.google.android.gms(各种其他库正在请求play-services-basement)

盛年不重来,一日难再晨,及时当勉励,岁月不待人。这篇文章主要讲述构建gradle时出错 - com.google.android.gms:各种其他库正在请求play-services-basement相关的知识,希望能为你提供帮助。
【构建gradle时出错 - com.google.android.gms(各种其他库正在请求play-services-basement)】我正在尝试使用Firebase-UI库将Facebook登录功能集成到我的android应用程序中。我正在关注本教程 -https://firebase.google.com/docs/auth/android/firebaseui?authuser=0
但是在尝试构建gradle时我遇到了以下错误:

com.google.android.gms库:play-services-basement正在[[15.0.1,15.0.1]]的各个其他图书馆请求,但已解析为16.0.1。禁用插件并使用./gradlew:app:dependencies检查依赖关系树。
下面是我的应用级别build.gradle文件
apply plugin: 'com.android.application'android { compileSdkVersion 28 defaultConfig { applicationId "company.com.mygame" 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 fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:28.0.0' implementation 'com.android.support.constraint:constraint-layout:1.1.3'implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.0'implementation 'com.facebook.android:facebook-android-sdk:4.37.0'implementation 'com.google.firebase:firebase-core:16.0.4' implementation 'com.firebaseui:firebase-ui-auth:4.2.0'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' }apply plugin: 'com.google.gms.google-services'

我看到下面的链接 -
com.google.android.gms:play-services-measurement-base is being requested by various other libraries
https://github.com/OneSignal/OneSignal-Gradle-Plugin/issues/37
但后来我得到了这个错误 -
Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.firebaseui:firebase-ui-auth:4.2.0] C:Usersme.gradlecaches ransforms-1files-1.1firebase-ui-auth-4.2.0.aarxxxAndroidManifest.xml as the library might be using APIs not available in 15 Suggestion: use a compatible library with a minSdk of at most 15, or increase this project's minSdk version to at least 16, or use tools:overrideLibrary="com.firebase.ui.auth" to force usage (may lead to runtime failures)

但问题仍然没有解决。我刚刚开始学习android,不知道我错过了什么。
答案我遇到过同样的问题
只需确保您拥有所有依赖项的最新版本。我使用Firebase核心和auth的当前版本。
您可以从here获取最新版本。在当前时间点使用最新版本:
在app / build.gradle中:
dependencies { ... // Add these code implementation 'com.google.firebase:firebase-core:16.0.8' implementation 'com.google.firebase:firebase-auth:16.2.0' }

在android / build.gradle中:
buildscript { ext { ... minSdkVersion = 16 ... } }

另一答案你的错误说:uses-sdk:minSdkVersion 15 cannot be smaller than version 16和你的build.gradleminSdkVersion 15。尝试将其更改为16,看看它是否适合您。
学习android的最好的。愿原力与你同在。
完了,走吧,
