NoClassDefFound Error on Android

[jamesdixon]

Some of my customers are seeing the app crash when trying to add a payment method on Android. This is the error I'm seeing:

Any idea what this might be?

Did you find a solution to this? Ran into a similar issue and played with a few things (updated the api version in build-extras.gradle) but that didn't help.

Thanks!

@adamfellon well, this issue has been a real killer for me because I haven't been able to reproduce it myself. That said, I added the following to build-gradles.extra and haven't seen any of these crashes in over a week.

dependencies {
    compile "com.google.android.gms:play-services-wallet:+"
}

[adamfellon]

That looks like it works for me! @Taracque Looks like they forgot an import or something over at Braintree. Think this commit ( https://github.com/braintree/braintree_android/commit/2c3d9ad9db68fa36e8290c979af6a809b451a865 ) fixes handling this error likely, so i'll hold off on a pr to add the dependcy.

@adamfellon glad to hear it and nice find!
