question

I'm trying to modify the SampleLoginWithAmazonAppForAndroid project (from: https://images-na.ssl-images-amazon.com/images/G/01/lwa/samples/SampleLoginWithAmazonAppForAndroid-src._TTH_.zip) to generate an authorization code that I can send to my embedded device, but I consistently get the following error message: "Error=invalid_scope_data error_description=lwa-invalid-parameter-bad-scope-data" If I use the mAuthManager.authorize call that comes with the sample project, it works fine. Here's my mAuthManager.authorize call (pulled from this guide: https://developer.amazon.com/public/solutions/alexa/alexa-voice-service/docs/authorizing-your-alexa-enabled-product-from-an-android-or-ios-mobile-app): private static final String PRODUCT_ID = "BLUMOO_V2_D21_EVK"; private static final String PRODUCT_DSN = "123456"; private static final String CODE_CHALLENGE = "OWQpS2ZGE3mNGkd-uK0CEYtI0MVzjEJ2EyAvLtEjtfE"; Bundle options = new Bundle(); String scope_data = "{\"alexa:all\":{\"productID\":\"" + PRODUCT_ID + "\", \"productInstanceAttributes\":{\"deviceSerialNumber\":\"" + PRODUCT_DSN + "\"}}}"; options.putString(AuthzConstants.BUNDLE_KEY.SCOPE_DATA.val, scope_data); options.putBoolean(AuthzConstants.BUNDLE_KEY.GET_AUTH_CODE.val, true); options.putString(AuthzConstants.BUNDLE_KEY.CODE_CHALLENGE.val, CODE_CHALLENGE); options.putString(AuthzConstants.BUNDLE_KEY.CODE_CHALLENGE_METHOD.val, "S256"); mAuthManager.authorize(APP_SCOPES, options, new AuthListener()); According to the debugger, the scope_data string is: {"alexa:all":{"productID":"BLUMOO_V2_D21_EVK", "productInstanceAttributes":{"deviceSerialNumber":"123456"}}} I've registered the product with AVS.

If it looks like I'm missing something so stupid that it's not worth pointing out, please point it out anyways. I'm an firmware developer by trade, so this is my first foray into this sort of stuff.
