Glide 4.10.0 : java.lang.IllegalStateException: GeneratedAppGlideModuleImpl is implemented incorrectly

First thing:

Have you changed annotationProcessor dependency:

implementation 'com.github.bumptech.glide:glide:4.10.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.10.0'

Also, it is critical that implementation & annotationProcessor version number is the same. Gradle will update the first automatically but not the second.

Second things:

Have you added proguard rules as follow:

-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep public enum com.bumptech.glide.load.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

Hope it will helps you. Thank you.

In my case, this bug happened when I tried to show a Google Map in my app. Specifically google-map-v3-beta SDK.

It looks like the SDK contains an obfuscated version of Glide that breaks when the app also uses Glide and the final AndroidManifest.xml contains a meta-data element called "GlideModule".

There is an issue for that in the google tracker: https://issuetracker.google.com/issues/132323222

Solution for me was to switch back to maps v2.

I faced similar issue with my apps. I upgraded Glide library from 4.9.0 to 4.11.0.

Before:

implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
implementation ('com.github.bumptech.glide:okhttp3-integration:4.9.0'){
    exclude group: 'glide-parent'
}

After:

implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'
implementation ('com.github.bumptech.glide:okhttp3-integration:4.11.0'){
    exclude group: 'glide-parent'
}

That fixed the problem.

I had this bug too. Probably you are using a library that used another Glide version, so you should use the same as the version of the Glide library that your library used it.

Just you need to put the version compiler the same version in glide implementation 'com.github.bumptech.glide:glide:4.11.0' kapt 'com.github.bumptech.glide:compiler:4.11.0'

Add this to android/build.gradle.

  buildscript {
   ext {
    excludeAppGlideModule = true
   }
