Version 1.3.0 aac-sdk
The Alexa Automotive Core (AAC) SDK is for automotive OEMs to integrate Alexa directly into vehicles. **v1.3.0** * v1.3.0 released on 2018-11-20 **Enhancements** Alexa Auto SDK now includes the following features and enhancements: * All changes from v1.1.1 and v1.2.0 * Android 8 and ARM v8a platform support. * Making calls to contacts from a locally paired mobile phone as long as the Alexa Auto SDK has a valid auth token. Read more about [Contact Uploader API](./modules/contact-uploader/README.md). * Redial, answer, terminate and decline calls using voice. End users can also send dual-tone multi-frequency (DTMF) via voice to interact with Interactive Voice Responders (IVRs). Read more here [Phone Call Controller](./modules/phone-control/README.md). * Switching to local media sources, generic controls and deep linking into 3rd party media applications compatible with the Amazon Media App Command and Control (MACC) specification using the External Media Player Interface 1.1. This allows customers to switch between a CD player, AM/ FM player and auxiliary input that is MACC compliant. Read more here [Handling External Media Adapter with MACCAndroidClient](./platforms/android/ALEXA.md#handlingexternalmediaadapterwithmaccandroidclient). * Enhancement for 3rd party wake word engine to enable cloud based verification. * Provides a way to override Template Runtime display card timeout values for RenderTemplate and RenderPlayerInfo by updating the [templateRuntimeCapabilityAgent Engine configuration](https://alexa.github.io/aac-sdk/modules/core/#configuring-the-engine) values. **Resolved Issues** No resolved issues. **Known Issues** * The Alexa Auto SDK does not re-discover Media Apps Command and Control (MACC) compliant apps if they are unresponsive after being idle for a long period (around 30 minutes). * The Alexa Auto SDK Engine becomes unresponsive if it receives PLAY directive during shutdown. However since shutdown is triggered when car ignition is turned off, there is not direct customer impact expected. * When a timer sounds during an Alexa to Alexa call, uttering "stop" ends the call not the timer. * Multiple automotive devices using the same account at the same time, can access contacts from phones paired across those devices.

## v1.3.0 released on 2018-11-20:
6+
7+
### Enhancements
8+
9+
Alexa Auto SDK now includes the following features and enhancements:
10+
11+
* Android 8 and ARM v8a platform support.
12+
* Making calls to contacts from a locally paired mobile phone as long as the Alexa Auto SDK has a valid auth token. Read more about [Contact Uploader API](./modules/contact-uploader/README.md).
13+
* Redial, answer, terminate and decline calls using voice. End users can also send dual-tone multi-frequency (DTMF) via voice to interact with Interactive Voice Responders (IVRs). Read more here [Phone Call Controller](./modules/phone-control/README.md).
14+
* Switching to local media sources, generic controls and deep linking into 3rd party media applications compatible with the Amazon Media App Command and Control (MACC) specification using the External Media Player Interface 1.1. This allows customers to switch between a CD player, AM/ FM player and auxiliary input that is MACC compliant. Read more here [Handling External Media Adapter with MACCAndroidClient](./platforms/android/ALEXA.md#handlingexternalmediaadapterwithmaccandroidclient).
15+
* Enhancement for 3rd party wake word engine to enable cloud based verification.
16+
* Provides a way to override Template Runtime display card timeout values for RenderTemplate and RenderPlayerInfo by updating the [templateRuntimeCapabilityAgent Engine configuration](https://alexa.github.io/aac-sdk/modules/core/#configuring-the-engine) values.
17+
18+
### Resolved Issues
19+
20+
No resolved issues.
21+
22+
### Known Issues
23+
24+
* The Alexa Auto SDK does not re-discover Media Apps Command and Control (MACC) compliant apps if they are unresponsive after being idle for a long period (around 30 minutes).
25+
* The Alexa Auto SDK Engine becomes unresponsive if it receives PLAY directive during shutdown. However since shutdown is triggered when car ignition is turned off, there is not direct customer impact expected.
26+
* When a timer sounds during an Alexa to Alexa call, uttering "stop" ends the call not the timer.
27+
* Multiple automotive devices using the same account at the same time, can access contacts from phones paired across those devices.
28+
29+
## v1.2.0 released on 2018-10-15:
30+
31+
### Enhancements
32+
33+
* Additional information related to the presentation of alerts is now available. The extended interface now includes Alert token, type, rendering time, and label if applicable when an alert is set and notification when an alert is deleted.
34+
* In the Navigation platform interface, ```SetDestination``` now provides business hours and contact information for a returned location when available.
35+
36+
### Resolved Issues
37+
38+
* If a location is not available, the location state is set to ```unavailable```. Previously it was treated as ```(0,0)``` which was a valid value for longitude and latitude.
39+
* Fixed an issue related to stopping an alert where there could be up to a 10 second delay before the alert completely stopped.
40+
* Fixed issue where the ```TemplateRuntime``` platform interface could not be registered before ```AudioPlayer```.

1. ```startAudioInput()``` is called when wake word detection is enabled. This occurs when the Engine is started if wake word is enabled by default, or when ```enabledWakewordDetection()``` is explicitly called by the application. When this happens, the application must start sending audio samples from the microphone to the Engine.

1. Audio is processed locally by the wake word engine until the wake word is detected. Once the wake word is detected, the Engine notifies the application that the dialog state has changed to "listening" and initiates a Recognize event with Alexa.
56+
57+
1. While in the listening state, audio data is sent to Alexa until the end of speech is detected. Once the end of speech is detected, Alexa sends a ```StopCapture``` directive to the Engine and the dialog state is changed to "thinking." Alexa then respond with additional directives in response to the speech request.
58+
59+
1. The application should continue to send audio to the Engine until ```stopAudioInput()``` is received. When wake word is enabled, this happens when the Engine is stopped, or when ```disableWakewordDetection()``` is explicitly called by the application.
