Android - Activity uses or overrides a deprecated API

Question

I have literally created a brand new Android Project on the latest Android Studio. The first thing I did was to add the `Realm' library to the project by adding the following to the gradle file:

compile 'io.realm:realm-android:0.80.3'

If I try to compile, I get the following error:

Note: C:\....\MainActivity.java uses or overrides a deprecated API.

Origin 2: C:\Users\Usmaan.gradle\caches\modules-2\files-2.1\io.realm\realm-android\0.80.3\7979d05ba7b919c53766bf98e31aaf0e9feb0590\realm-android-0.80.3.jar Error:duplicate files during packaging of APK C:...\app\build\outputs\apk\app-debug-unaligned.apk Path in archive: META-INF/services/javax.annotation.processing.Processor Origin 1: C:\Users\Usmaan.gradle\caches\modules-2\files-2.1\com.jakewharton\butterknife\6.1.0\63735f48b82bcd24cdd33821342428252eb1ca5a\butterknife-6.1.0.jar You can ignore those files in your build.gradle: android {
packagingOptions { exclude 'META-INF/services/javax.annotation.processing.Processor' } Error:Execution failed for task ':app:packageDebug'.

Any ideas?

It looks like you are also using Butterknife? Have you tried adding the below to your build.gradle:

android {
  ...

  packagingOptions {
    exclude 'META-INF/services/javax.annotation.processing.Processor'
  }
}
