The KeenASR SDK for Android includes support for the armeabi-v7a and arm64-v8a architectures.

Tip: The minimum Android SDK API level currently supported is API 21 (Android 5.0, Lollipop)

To install the SDK, follow the steps below:

Prerequisite: Download the KeenASR SDK file and the ASR Bundle

• Download the SDK and ASR Bundle.

1. Add the KeenASR AAR file to your project

1. In Android Studio choose File > New > New Module > Import JAR/AAR Package and select the KeenASR.aar file; this creates the KeenASR module in your project.

2. Add build dependency: Choose File > Project Structure > Dependencies, then click the plus sign (+) at the bottom and choose Module Dependency > KeenASR. Click OK to finish.

2. Update the AndroidManifest.xml file

Add the following lines within the manifest element

<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.WAKE_LOCK" />

3. Add the ASR Bundle to the app

1. Unpack the ASR Bundle you download on your local disk.

2. Choose File > New > Folder > Assets Folder > Finish to create the assets folder.

3. Copy the ASR Bundle you downloaded (e.g., keenB2mQT-nnet3chain-en-us) to the app/src/main/assets/ folder. You should end up with a app/src/main/assets/keenB2mQT-nnet3chain-en-us folder. Android studio will recognize the new folder and you should be able to see the assets/keenB2mQT-nnet3chain-en-us listed in the left-side navigation tree.

Warning: The text files in the ASR Bundle are using LF line break characters. By default, Git on Windows modifies line break characters from LF to CRLF, which will prevent The KeenASR SDK from properly initializing (the app will just crash). Check the Github page on how to deal with line endings for instructions on how you can configure your global or repository Github settings to avoid this problem. For the SDK to function correctly, all text files in the ASR Bundle (e.g. app/src/main/assets/keenB2mQT-nnet3chain-en-us) need to be checked out with LF line break characters. The problem with line endings can also occur if you manually edit the text file in a Windows editor.
