Caused by: java.lang.NumberFormatException: For input string: "simple_response" about dialogflow-android-client HOT 19 CLOSED

My team encountered the exact same crash as of yesterday.

This problem appears to occur on Android when an agent uses an intent with a default text response (no webhook). We fixed it by using a webhook to fulfill all of our intents.

Same issue. wondering if someone knows the fix...

Hi @vishalkharat ,

We didn't really fix it. We avoided the crash by only using webhooks to generate responses to intents.

When creating an intent in API.AI you have the option to check "use webhook" instead of using text responses. My team found that the crash only occurs when we used the local API.AI text responses. We modified all of our intents to use webhooks so that our fulfillment server would generate text responses. I don't know why this works; we discovered it through trial and error.

If you don't have a fulfillment server (e.g. your agent lives entirely in API.AI) then this solution won't work for you.

@johnflynn90 Thanks for reply.

I think this can be fixed by updating libai sdk. As api.ai is sending messages object in two formats as part of response. Because of this android app fails to map these objects, and results in a crash.
Following is the sample response.
"messages":[
{
"type":"simple_response",
"platform":"google",
"textToSpeech":"sample text to convert"
},
{
"type":0,
"speech":"sample text to convert"
}
]

Updating libai sdk how ? I am using the latest 1.4.8 in my build gradle , still this issue.
I think the issue lies in the onResult method
I may be wrong though

Hello friends!

Please no worries, we are working on problem!

Thank you for your patience

from dialogflow-android-client.

The issue was fixed in Java SDK and will be available on next release.

from dialogflow-android-client.

When is the next release coming for android because I am now frequently getting this issue in my android app. And if you can tell me any workaround please let me know.
Thanks

from dialogflow-android-client.

There is a kind of workaround. You may manually build and install Java SDK from GitHub repository:

git clone https://github.com/api-ai/apiai-java-client.git
cd apiai-java-client/
mvn install

This commands will checkout the code, build it and install library of version 1.4.9 into your local maven repository.

Next step is to change dependency version in your build.gradle file:

find line

compile 'ai.api:libai:1.4.8'

and replace it with

compile 'ai.api:libai:1.4.9'

rebuild your project.

I've build apiAISampleApp application and everything was fine.
Would you be so kind to provide the call stack traces?

Fixed.
