Amazon Web Services(AWS) Lambda Canonicalization Error for Turkish Language
I am facing canonicalization problem while using aws-android-sdk-lambda from Android phone.While function call it somehow uses phone's language, btw it is Turkish, so I get SigningKeyDoesntMatchException. If I change phone language to English, it reaches aws correctly. As you can see "x-amz-ä±nvocation-type" string is corrupted, it should be like "x-amz-invocation-type".
As a solution I tried to change phone language to English before function call, but I need a permanent solution.It drives me crazy. Thank you for your time.
