尽管有更新,但应用程序更新仍不起作用

Ibr*_*zin 8 android kotlin google-play android-studio

我正在尝试在我的应用程序中实现应用程序内更新,以便当有新的更新时,用户可以看到它。

我已仔细遵循此处列出的所有步骤 - https://developer.android.com/guide/playcore/in-app-updates/kotlin-java

但由于某些原因,更新对话框没有显示......

活动.kt

override fun onCreate(savedInstanceState: Bundle?) {

    setTheme(R.style.Theme_DirectMusicPlayer)
    super.onCreate(savedInstanceState)
    initViews()
    setContentView(binding.root)
}


private fun initViews(){
    checkForUpdate()
}

 private fun checkForUpdate(){

    appUpdateManager = AppUpdateManagerFactory.create(this)

    // Returns an intent object that you use to check for an update.
    val appUpdateInfoTask = appUpdateManager.appUpdateInfo

    // Checks that the platform will allow the specified type of update.

    appUpdateInfoTask.addOnSuccessListener { appUpdateInfo ->

        if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE

           {

            // Request the update.
            appUpdateManager.startUpdateFlowForResult(
                // Pass the intent that is returned by 'getAppUpdateInfo()'.
                appUpdateInfo,
                // Or 'AppUpdateType.FLEXIBLE' for flexible updates.
                AppUpdateType.FLEXIBLE,
                // The current activity making the update request.
                this,
                // Include a request code to later monitor this update request.
                Constants.MY_REQUEST_CODE
            )
        }
        else{
            Toast.makeText(this, "No update yet", Toast.LENGTH_LONG).show()
        }
    }
    //Create a listener to track request state updates.
    installStateUpdatedListener = InstallStateUpdatedListener { state ->

        when (state.installStatus()) {

            InstallStatus.DOWNLOADING -> {
                val bytesDownloaded = state.bytesDownloaded()
                val totalBytesToDownload = state.totalBytesToDownload()

                //show download progress
            }

            InstallStatus.DOWNLOADED -> {
                //show SnackBar
                showInstallSnackBar()
            }
            InstallStatus.INSTALLED -> {
                appUpdateManager.unregisterListener(installStateUpdatedListener)
            }

            else -> {
                //do something
            }
        }
    }

    // Before starting an update, register a listener for updates.
    appUpdateManager.registerListener(installStateUpdatedListener)


}


private fun showInstallSnackBar(){

    Snackbar.make(
        findViewById(android.R.id.content),
        "An update has just been downloaded.",
        Snackbar.LENGTH_INDEFINITE
    ).apply {
        setAction("RESTART") { appUpdateManager.completeUpdate() }
        setActionTextColor(ContextCompat.getColor(this@PermissionActivity, R.color.app_name_color))
        show()
    }

}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

    super.onActivityResult(requestCode, resultCode, data)

    if (requestCode == Constants.MY_REQUEST_CODE) {
        if (resultCode != AppCompatActivity.RESULT_OK) {
            // If the update is cancelled or fails,
            // you can request to start the update again
            checkForUpdate()
        }
    }
}

override fun onResume() {
    super.onResume()

    appUpdateManager
        .appUpdateInfo
        .addOnSuccessListener { appUpdateInfo ->
            // If the update is downloaded but not installed,
            // notify the user to complete the update.
            if (appUpdateInfo.installStatus() == InstallStatus.DOWNLOADED) {
                showInstallSnackBar()
            }
        }
  }
}

去测试:

  1. 我上传到测试轨道(使用应用内更新代码)
  2. 然后我使用可共享链接下载了上面相同的应用程序包
  3. 然后在我的代码中,我将版本代码增加到比步骤 1中的版本代码更高的版本代码
  4. 然后,我生成了另一个签名包并上传到相同的内部测试轨道。
  5. 现在,我复制了步骤 4中应用程序的 URL并访问了...在那里我看到了“更新”——这意味着有可用的更新。(我没有点击Playstore上的更新)
  6. 我关闭了 PlayStore 并打开了我的应用程序...以为会显示应用程序内更新对话框,但没有显示任何内容...但在 PlayStore 上,它显示“更新”。

我还清除了缓存,等了几个小时但什么也没发生。

当没有更新时,我也没有收到设置为“无更新”的 Toast 消息...这表明肯定有更新...但来自 Google 的更新对话框未显示。
