最近我添加了Google Play Integrity。我已经将Google服务json文件添加到项目中，启用了Google云控制台上的API，并更新了移动的上的Google Play商店，但我仍然得到错误代码-1 [Integrity Api not found]
我的代码是

val nonce: String = generateNonce() //generated nonce at my side

        // Create an instance of a manager.
        val integrityManager: IntegrityManager = IntegrityManagerFactory.create(context.applicationContext)

        // Request the integrity token by providing a nonce.
        val integrityTokenResponse: Task<IntegrityTokenResponse> = integrityManager.requestIntegrityToken(
                IntegrityTokenRequest.builder()
                        .setNonce(nonce)
                        .build())
        integrityTokenResponse.addOnSuccessListener { response ->
            val integrityToken: String = response.token()
            println("integrityToken:="+integrityToken)
        }
        integrityTokenResponse.addOnFailureListener { e ->
            println("integrityToken Error:="+e)
        }

任何帮助都将不胜感激。
