我尝试在我的应用程序之一中实现应用内更新功能。我集成了应用内代码片段，但是当我运行代码时，它会抛出一条错误消息。

代码 ：

 class MainActivity : AppCompatActivity() {
    private val REQUEST_CODE: Int = 123
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        initInAppUpdate()
    }

    private lateinit var appUpdateManager: AppUpdateManager
    private lateinit var listener: InstallStateUpdatedListener
    private fun initInAppUpdate() {
        // Create instance of the IAUs manager.
        appUpdateManager = AppUpdateManagerFactory.create(this)

        // Add state listener to app update info task.
        appUpdateManager.appUpdateInfo.addOnSuccessListener { appUpdateInfo ->
            // If there is an update available, prepare to promote it.
            Log.d("TAG","====>${appUpdateInfo.updateAvailability()}")
            if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE) {

                appUpdateManager.startUpdateFlowForResult(
                    // Pass the intent that is returned by 'getAppUpdateInfo()'.
                    appUpdateInfo,
                    // Or 'AppUpdateType.IMMEDIATE for immediate updates.
                    AppUpdateType.FLEXIBLE,
                    // The current activity.
                    this,
                    REQUEST_CODE
                )
            }

            // If the process of downloading is finished, start the completion flow.
            if (appUpdateInfo.installStatus() == InstallStatus.DOWNLOADED) {
                Log.d("TAG","====> InstallStatus.DOWNLOADED")
            }
        }
            .addOnFailureListener { e ->
                Log.d("TAG","====> Failed : ${e.printStackTrace()}")
            }

        // Create a listener to track downloading state updates.
        listener = InstallStateUpdatedListener { state ->
            // Update progress indicator, request user to approve app reload, etc.
            Log.d("TAG","====> Current State : $state")
        }

        // At some point before starting an update, register a listener for updates.
        appUpdateManager.registerListener(listener)
    }

    override fun onDestroy() {
        super.onDestroy()
        // At some point when status updates are no longer needed, unregister the listener.
        appUpdateManager.unregisterListener(listener)
    }
}

错误 ：

您正在测试的应用程序的包名称似乎与您的生产应用程序不同，或者您正在使用调试版本。确保您使用相同的包名称和相同的签名密钥库。
