I’m trying to use glide in Android Studio to add images. But when I added It, It showing me this error: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve 'com.github.bumptech.glide:glide:4.13.2'

app:gradll

dependencies
{
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation 'com.android.support:appcompat-v7:26.+'
  implementation 'com.android.support.constraint:constraint-layout:1.0.2'
  testImplementation 'junit:junit:4.12'
  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:4.13.2'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.13.2'
}

>Solution :

Please check that you added this code in:

app:gradle

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.13.2'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.13.2'
}

build:gradle

repositories {
      google()
      mavenCentral()
}

Also try Invalidate -> Cache Restart.
