Amplify-android: What is the pro-guard rules for AWS S3 ?

Created on 28 Oct 2020 · 2Comments · Source: aws-amplify/amplify-android

I have using below library in my application to upload data to Amazon S3.

implementation 'com.amplifyframework:aws-storage-s3:1.4.2'
implementation 'com.amplifyframework:aws-auth-cognito:1.4.2'

It's working fine in debug mode. Now I have generated a signed APK using below the Proguard configuration, with minifyEnabled true.

-keepnames class com.amazonaws.**
-keepnames class com.amazon.**
-keep class com.amazonaws.services.**.*Handler
-dontwarn com.fasterxml.jackson.**
-dontwarn org.apache.commons.logging.**
-dontwarn org.apache.http.**
-dontwarn com.amazonaws.http.**
-dontwarn com.amazonaws.metrics.**

Now my app keeps on crashing when I upload upload videos to S3.

Error log:

Please let me know of any solutions. Please don't advise to set minifyEnabled false.
