Please help me.I am stuck in this problem for a few days.

回答1:

I had exactly the same problem. I solve this issue with updating every Google support library to the latest version (27.1.0 in time of writing this solution). Also I updated compileSdkVersion to version 27 and buildToolsVersion to version 27.0.3. I hope that this will solve you problem.

回答2:

My issue was related due to the using of different version of same library. One of my sub dependencies was referring to a different version of com.android.support:design, so I forced the version in build.gradle with

configurations.all {     resolutionStrategy {         force 'com.android.support:support-v4:27.1.0'         force 'com.android.support:design:27.1.0'     } } 

回答3:

just you have to add multidex true and add one dependency to it. check code:

defaultConfig {     ...     multiDexEnabled true } 

add dependency:

dependencies {  compile 'com.android.support:multidex:1.0.1' } 

and if you want to know multidex in details please lokk into below link : https://developer.android.com/studio/build/multidex.html

Happy Coding...

回答4:

You should enable multidex property in your build.gradle file

android {      compileSdkVersion ..     buildToolsVersion '...'      defaultConfig {        ...        targetSdkVersion ..        multiDexEnabled true  // this line will solve this problem    } }

Try this ...

apply plugin: 'com.android.application'  android { compileSdkVersion 27 buildToolsVersion "27.0.2" defaultConfig {     applicationId "com.example.invinciblesourav.flacom"     minSdkVersion 18     targetSdkVersion 27     versionCode 1     versionName "1.0"      testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"  } buildTypes {     release {         minifyEnabled false         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'     } } sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/'] } } }  dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {     exclude group: 'com.android.support', module: 'support-annotations' })  compile ('com.android.support:appcompat-v7:27.+') compile 'com.android.support.constraint:constraint-layout:1.0.2' compile 'com.google.firebase:firebase-auth:11.0.4' compile 'de.hdodenhof:circleimageview:2.1.0' compile 'com.theartofdev.edmodo:android-image-cropper:2.3.+' compile 'com.google.firebase:firebase-core:11.0.4' compile 'com.google.firebase:firebase-database:11.0.2' compile 'com.google.firebase:firebase-storage:11.0.4' compile 'com.android.support:design:25.3.1' compile 'com.squareup.picasso:picasso:2.4.0' testCompile 'junit:junit:4.12' }   apply plugin: 'com.google.gms.google-services'
