If you need help with understanding how to implement something in particular then we suggest that you first look into our developer guide. You can also simplify your process of creating an application by using Mobile Hub.

AWS China confirms it as a bug..

[mutablealligator]

Sorry for the inconvenience caused. We released 2.6.6 that fixes this issue. Can you check it out?

Hi,

I tried 2.6.6 recently, the Exception does not exist anymore, but still can't connect to AWS IoT.

The sample program I run was https://github.com/awslabs/aws-sdk-android-samples/tree/master/AndroidPubSub. with similar configuration, I can connect to AWS IoT us-west-2 region, but for cn-north-1， it always failure.

I tried use manual build keystore to access, I can't connect to AWS IoT cn-north-1 region also.
The way I do is: store private key and certificate to 2 strings, then create keystore, then use it to connect. but failed always.

 try {
        if (AWSIotKeystoreHelper.isKeystorePresent(keystorePath,keystoreName)){
            if(AWSIotKeystoreHelper.keystoreContainsAlias(certificateId,keystorePath,keystoreName,keystorePassword)){
                AWSIotKeystoreHelper.deleteKeystoreAlias(certificateId,keystorePath,keystoreName,keystorePassword);
            }
        }
    } catch (Exception e) {
        Log.e(LOG_TAG, "An error occurred delete alias from keystore.", e);
    }
    AWSIotKeystoreHelper.saveCertificateAndPrivateKey(certificateId, certPem, keyPem,keystorePath,keystoreName,keystorePassword);

Could you please help have a check?

Best regard
Philip
