am getting error after i created amazon coginto in android

Question

Hi am doing a project which syncs the data to amazon coginto and its working fine, and successfully signed apk too.

Now the problem is am getting error after debug

"Unrecognized suffix for the AWS http client class name b"

Answer 1

You probably turn on Proguard and have class name obfuscated. The SDK does reflection based on the class name. Without it some feature may not work correctly. Please see the instruction https://github.com/aws/aws-sdk-android/blob/master/Proguard.md for configuration.

Answer 2

Girdhar G. Patel's solution works for version 1 of the aws sdk and the source for the answer is here: https://aws.amazon.com/blogs/mobile/using-proguard-with-the-aws-sdk-for-android/

If you're using version two you'll need a different proguard configuration to get it working: (source: https://github.com/krschultz/android-proguard-snippets/blob/master/libraries/proguard-aws-2.1.5.pro)

# These options are the minimal options for a functioning application
