android studio with Java compiler error: string too large to encode using UTF-8 written instead as 'STRING_TOO_LARGE'

I had encountered the same and fixed by clear the build cache .

For the time being, you can downgrade Gradle version to resolve this issue. Use gradle 3.1 version like 3.1.3 below.

  classpath 'com.android.tools.build:gradle:3.1.3'

I was stuck on this problem and read through this topic and no one provided a future solution. I did NOT want to revert back my Gradle. Therefore, here is the link to the updated dependencies https://github.com/stripe/stripe-android. Look for the "Android Studio (or Gradle)" section and you should see this "implementation 'com.stripe:stripe-android:8.1.0'" also you might need to add "-keep class com.stripe.android.** { *; }" if you are enabling minification in your build.gradle file.

Overall Stripe has stopped updating their own "Stripe docs" which can be found here. To give them credit their docs are helpful and should be read at least once, but be mindful that most of the docs are out date when I wrote this...

Hope this helps :)
