为什么应用内更新没有按预期更新应用？

Question

以下是我的SplashActivity.kt 中的代码。每当有可用更新时，大多数情况下它根本不会显示，但我认为这不是因为我的代码中有任何错误，而是因为我了解到需要一些时间来向用户展示新更新。我现在担心的是，当它显示应用内更新屏幕时，它会关闭并且应用程序会继续下一个屏幕，并且不会要求用户更新应用程序以继续使用该应用程序。我是不是搞错了？

    @Suppress("DEPRECATION")
class SplashActivity : AppCompatActivity() {

    private lateinit var binding: ActivitySplashBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        binding = ActivitySplashBinding.inflate(layoutInflater)
        setContentView(binding.root)

        callInAppUpdate()
        window.setFlags(
            WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN
        )
        Handler().postDelayed(
            {
                val currentUserID = FirestoreClass().getCurrentUserID()

                if (currentUserID.isNotEmpty()) {
                    startActivity(Intent(this@SplashActivity, HomeActivity::class.java))
                } else {
                    startActivity(
                        Intent(
                            this@SplashActivity,
                            LoginActivity::class.java
                        )
                    )
                }
                finish()
            },
            2500
        )
    }

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

        if (data == null) return

        if (requestCode == updateRequestCode) {
            Toast.makeText(this, "Downloading", Toast.LENGTH_SHORT).show()

            if (resultCode != RESULT_OK) {
                Log.d("TAG", "update flow failed $resultCode")
            }
        }
    }

    private val updateRequestCode = 1612

    private fun callInAppUpdate() {

        val appUpdateManager = AppUpdateManagerFactory.create(this)
        val appUpdateInfoTask = appUpdateManager.appUpdateInfo
        appUpdateInfoTask.addOnSuccessListener { appUpdateInfo ->
            if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)
            ) {
                appUpdateManager.startUpdateFlowForResult(
                    appUpdateInfo, AppUpdateType.IMMEDIATE, this, updateRequestCode
                )
            }
        }

    }

}

编辑：

我将postDelayed 移至addOnSuccessListener，fun callInAppUpdate() 现在如下所示。

    private fun callInAppUpdate() {

    val appUpdateManager = AppUpdateManagerFactory.create(this)
    val appUpdateInfoTask = appUpdateManager.appUpdateInfo
    appUpdateInfoTask.addOnSuccessListener { appUpdateInfo ->
        if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
            && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)
        ) {
            appUpdateManager.startUpdateFlowForResult(
                appUpdateInfo, AppUpdateType.IMMEDIATE, this, updateRequestCode
            )
        }else{
            Handler().postDelayed(
                {
                    val currentUserID = FirestoreClass().getCurrentUserID()

                    if (currentUserID.isNotEmpty()) {
                        startActivity(Intent(this@SplashActivity, DashboardActivity::class.java))
                    } else {
                        startActivity(
                            Intent(
                                this@SplashActivity,
                                LoginWithPhoneNumberActivity::class.java
                            )
                        )
                    }
                    finish()
                },
                2500
            )
        }
    }

}

您可以实现如下行为：

class SplashActivity : AppCompatActivity() {

private val updateRequestCode = 1612

private lateinit var binding: ActivitySplashBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    binding = ActivitySplashBinding.inflate(layoutInflater)
    setContentView(binding.root)

    callInAppUpdate()
    window.setFlags(
        WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN
    )

}

public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (data == null) return

    if (requestCode == updateRequestCode) {
        Toast.makeText(this, "Downloading", Toast.LENGTH_SHORT).show()
        if (resultCode != RESULT_OK) {
            Log.d("TAG", "update flow failed $resultCode")
            navigate()
        }
    }
}

private fun navigate(){
    Handler().postDelayed(
        {
            val currentUserID = FirestoreClass().getCurrentUserID()

            if (currentUserID.isNotEmpty()) {
                startActivity(Intent(this@SplashActivity, DashboardActivity::class.java))
            } else {
                startActivity(
                    Intent(
                        this@SplashActivity,
                        LoginWithPhoneNumberActivity::class.java
                    )
                )
            }
            finish()
        },
        2500
    )
}



private fun callInAppUpdate() {

    val appUpdateManager = AppUpdateManagerFactory.create(this)
    val appUpdateInfoTask = appUpdateManager.appUpdateInfo
    appUpdateInfoTask.addOnSuccessListener { appUpdateInfo ->
        if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
            && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
            appUpdateManager.startUpdateFlowForResult(
                appUpdateInfo, AppUpdateType.IMMEDIATE, this, updateRequestCode
            )
        }
        else {
            navigate()
        }
    }

  }
}

postDelayed 中有导航逻辑。您在 2500 毫秒后明确导航到新活动。所以代码完全按照你写的那样做。

如果您想在检查更新后进行导航，那么您可能应该将导航逻辑移至 addOnSuccessListener，尽管它看起来也像是一个 hack。无论哪种方式，我都不会在启动屏幕中进行此检查，而是在一些没有设置计时器导航的“静态”屏幕中进行检查
