AndroidPubSub Sample does not work!!!

[frankmuellr]

This issue was originally opened by @iwwork as a PR in the sample app repo:
awslabs/aws-sdk-android-samples#308

Which AWS Services are you utilizing?
AWS IoT

Provide code snippets (if applicable)
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

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 ,

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

If you have Regions.US_EAST_1 as the region value, please replace it with us-east-1 instead.

[iwwork]

@minbi this does not work.

[minbi]

Can you elaborate or potentially provide a stacktrace?

[desokroshan]

Sounds like this issue has been resolved as mentioned in #750. Closing this issue.

Hi @iwwork ,

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

If you have Regions.US_EAST_1 as the region value, please replace it with us-east-1 instead.

this work just write the region in lowercase with - instade of _ and Caused by: java.lang.IllegalArgumentException: Failed to read CognitoIdentity please check your setup or awsconfiguration.json file will be initialise
