AndroidPubSub Sample does not work!!!

[iwwork]

Followed the instruction https://github.com/awslabs/aws-sdk-android-samples/tree/master/AndroidPubSub to set the parameter on the AWS cloud

Downloaded the whole code from https://github.com/awslabs/aws-sdk-android-samples

Used Android Studio 3.3.1 to open the folder AndroidPubSub

Changed the following part
PubSubActivity.java
// IoT endpoint
// AWS Iot CLI describe-endpoint call returns: XXXXXXXXXX.iot..amazonaws.com
private static final String CUSTOMER_SPECIFIC_ENDPOINT = "REPLACE_ME";
// Name of the AWS IoT policy to attach to a newly created certificate
private static final String AWS_IOT_POLICY_NAME = "REPLACE_ME";

awsconfiguration.json
"PoolId": "REPLACE_ME",
"Region": "Regions.US_EAST_1"

Sync, Build and Run App on emulator9.0 or Mobile Phone8.0, the result in Logcat is

com.amazonaws.demo.androidpubsub W/o.androidpubsu: Verification of com.amazonaws.logging.Log com.amazonaws.logging.LogFactory.getLog(java.lang.String) took 100.996ms

Seems that the AWS modules do not work in the App.

How to deal with this problem?
Should there some other code be added?

Hi @iwwork@, sorry you are running into issues using our PubSub sample app. I've opened the following issue in the AWS Android SDK repo, and will close this PR, since it's really just an issue.
aws-amplify/aws-sdk-android#719

Please watch the issue for updates.
