Implementation

To enable the retrieval of Trust Technologies hosted packages via Gradle, the first step is to add your repository to the build.gradle file (project level).

To do add the following, at any location, to your build.gradle file:

repositories {

maven { url" https://dl.cloudsmith.io/q5Eobaq15KV0Rlk3/trusttechnologies/bioidentityv3/maven/" }

}

After the repository is added to the build.gradle file, all that is left is to specify the dependency in the dependencies section of the project build.gradle file (app level).

To do this add the below to your build.gradle file (app level):

dependencies {

implementation 'com.trust.bioidentity:Bioidentity:1.0.1'

}

See the actual version here.

Permissions

For the correct use of the SDK camera permissions are needed.

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