Android中“无法合并dex错误” _Android

人生处万类,知识最为贤。这篇文章主要讲述Android中“无法合并dex错误”相关的知识，希望能为你提供帮助。
Gradle文件和android Manifest如下所示。我尝试了Stack Overflow上的所有解决方案。
获得此例外：

com.android.builder.dexing.DexArchiveMergerException：无法合并dex

App Gradle

apply plugin: 'com.android.application'android { compileSdkVersion 26 defaultConfig { applicationId "com.bharat.photoblog" minSdkVersion 21 targetSdkVersion 26 versionCode 1 versionName "1.0" multiDexEnabled true 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.constraint:constraint-layout:1.0.2' implementation 'com.google.firebase:firebase-auth:11.8.0' implementation 'com.google.firebase:firebase-storage:11.8.0' testImplementation 'junit:junit:4.12' implementation 'com.google.firebase:firebase-firestore:11.8.0' implementation 'com.theartofdev.edmodo:android-image-cropper:2.6.+' implementation 'de.hdodenhof:circleimageview:2.2.0' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' implementation 'com.github.bumptech.glide:glide:4.6.1' annotationProcessor 'com.github.bumptech.glide:compiler:4.6.1' implementation 'com.android.support:design:26.1.0' }apply plugin: 'com.google.gms.google-services'

Project Gradle

buildscript {repositories { google() mavenCentral() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1'// NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files classpath 'com.google.gms:google-services:3.1.0' } }allprojects { repositories { google() jcenter() } }task clean(type: Delete) { delete rootProject.buildDir }

清单文件

< ?xml version="1.0" encoding="utf-8"?> < manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.bharat.photoblog"> < uses-permission android:name="android.permission.INTERNET" /> < uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> < uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> < 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> < activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity" android:theme="@style/Base.Theme.AppCompat" /> < activity android:name=".LoginActivity" /> < meta-data android:name="preloaded_fonts" android:resource="@array/preloaded_fonts" /> < activity android:name=".RegisterActivity" /> < activity android:name=".SettingActivity" /> < /application> < /manifest>

答案我认为appcompat-v7:26.1.0与Firebase 11.8.0不完全兼容尝试更新到appcompat-v7:27.0.2 ..我曾经遇到过这个问题，那就是解决方案
另一答案请更新： -
com.google.android.gms:play-services:11.2.2
至
com.google.android.gms:play-services:11.4.0。
然后：-
【Android中“无法合并dex错误”】清理并重建项目。
