Failed to find byte code for com/kount/api/DataCollector$CompletionHandler

I just clone the update to date code to local and want import into the android studio. first, the compile is successful, but when I run the demo, it gets an error as following:

Failed to find byte code for com/kount/api/DataCollector$CompletionHandler

I have found some solutions in websites, many of them say that is a proguard issue. but when I add the codes -dontwarn com.kount.** in the ‘proguard.pro’ file , it is still having this problem. Thank you.

android studio version is 3.1.3 classpath ‘com.android.tools.build:gradle:3.1.3’

update

When I check the gradle in the module of BraintreeDataCollector, it sees:

def deviceCollectorVersion = 'kount-data-collector-3.2.jar'

dependencies {
    // TODO `api` is the proper keyword for this dependency
    // Although when we try to add this to our releaseJar
    // We don't have access to configurations.(compile|api)
    // So this needs more investigation.
    // For now, revert back to `compile` keyword
    compile files('libs/' + deviceCollectorVersion)
}

I just follow the lib and see the package of com.kount.api.DataCollector . It has just one class BuildConfig,not has another one. it is saying that there is not a class called CompletionHandler in its source codes. I just guess that the version is wrong.

@nb312 we were able to reproduce this on another machine. The issue seems to stem from Instant Run being enabled. You can disable Instant Run as a temporary fix.

We’ll look more into the issue around Instant Run not working for BraintreeDataCollector.

@quinnjn thank you a lot for answer me.
