I'm trying to load image from Firebase using Glide. I start to meet error when I trying to implement Glide. During gradle sync, everything is fine. But, when i clean and rebuild the program, it will show following error.

`Program type already present: com.bumptech.glide.gifdecoder.GifDecoder$BitmapProvider Message{kind=ERROR, text=Program type already present: com.bumptech.glide.gifdecoder.GifDecoder$BitmapProvider, sources=[Unknown source file], tool name=Optional.of(D8)}`

I'm using sdk 26 as I met runtime error during use of sdk 27. I have made sure all the dependencies are not override sdk 27.

gradle:project

buildscript {



repositories {

    google()

    jcenter()

    maven

            {

                url "https://maven.google.com"

            }

}

dependencies {

    classpath 'com.android.tools.build:gradle:3.1.0'

    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()

    jcenter()

}

}



task clean(type: Delete) {

delete rootProject.buildDir

}

gradle: app

apply plugin: 'com.android.application'



android {

compileSdkVersion 26

defaultConfig {

    applicationId "com.example.user.uploadimage7"

    minSdkVersion 21

    targetSdkVersion 26

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

I have tried "exclude group: "com.android.support" but it doesn't work

I recommend you to update your SDK to version 27 and do the following changes. First, update your gradle to the latest version 3.2.1:

classpath 'com.android.tools.build:gradle:3.2.1'

Now change the following lines of code:

implementation 'com.google.firebase:firebase-core:16.0.1'

implementation 'com.google.firebase:firebase-storage:16.0.1'

implementation 'com.google.firebase:firebase-auth:16.0.1'

implementation 'com.firebaseui:firebase-ui-storage:3.1.0'

to

implementation 'com.google.firebase:firebase-core:16.0.5'

implementation 'com.google.firebase:firebase-storage:16.0.5'

implementation 'com.google.firebase:firebase-auth:16.0.5'

implementation 'com.firebaseui:firebase-ui-storage:4.2.1'

And for Glide, please change this line:

implementation "com.github.bumptech.glide:glide:4.3.1"

to

implementation "com.github.bumptech.glide:glide:4.7.1"

The error is solved by deleting the duplicate .jar in the libs folder
