Getting started

Installing the SDK

On your build.gradle file add the following dependencies:

implementation('io.yesid.sdk.android:touchless:0.2.2-beta@aar'){
    transitive = true
}

On your settings.gradle file add the following urls:

maven {
    url 'https://gitlab.com/api/v4/projects/29462567/packages/maven'
}
jcenter()
maven {
    url 'https://jfrog.yesid.tech/artifactory/libs-release-local'
}

Permissions

On your AndroidManifest.xml file you need to add the following permissions:

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

On your Main Activity ensure permissions are granted for the above permissions.

private fun allRuntimePermissionsGranted(): Boolean {
    for (permission in REQUIRED_RUNTIME_PERMISSIONS) {
        permission.let {
            if (!isPermissionGranted(this, it)) {
                return false
            }
        }
    }
    return true
}

private fun getRuntimePermissions() {
    val permissionsToRequest = ArrayList<String>()
    for (permission in REQUIRED_RUNTIME_PERMISSIONS) {
        permission.let {
            if (!isPermissionGranted(this, it)) {
                permissionsToRequest.add(permission)
            }
        }
    }

    if (permissionsToRequest.isNotEmpty()) {
        ActivityCompat.requestPermissions(
            this,
            permissionsToRequest.toTypedArray(),
            PERMISSION_REQUESTS
        )
    }
}

private fun isPermissionGranted(context: Context, permission: String): Boolean {
    if (ContextCompat.checkSelfPermission(
            context,
            permission
        ) == PackageManager.PERMISSION_GRANTED
    ) {
        Log.i(TAG, "Permission granted: $permission")
        return true
    }
    Log.i(TAG, "Permission NOT granted: $permission")
    return false
}

companion object {
    private const val TAG = "EntryChoiceActivity"
    private const val PERMISSION_REQUESTS = 1

    private val REQUIRED_RUNTIME_PERMISSIONS =
        arrayOf(
            Manifest.permission.CAMERA
        )
}

Then onCreate you can check if the permission are available or not

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    // Your other code here
    if (!allRuntimePermissionsGranted()) {
        getRuntimePermissions()
    }
}
