Android，当我使用应用内更新时发生 InstallException

Android, InstallException occurs when I use in-app updates(Android，当我使用应用内更新时发生 InstallException)

问题描述

在 Google I/O 2019 中，新增了应用内更新.

In Google I/O 2019, In-app update is added newly.

所以我尝试按照文档使用它:https://developer.android.com/guide/app-bundle/in-app-updates

So I am trying to use it following the document: https://developer.android.com/guide/app-bundle/in-app-updates

但它发送了一个类似的 InstallException:

But it sent an InstallException like:

com.google.android.play.core.tasks.RuntimeExecutionException: com.google.android.play.core.install.InstallException: Install Error: -6
    at com.google.android.play.core.tasks.k.getResult(Unknown Source:18)
    at com.eastriver.workingtimer.ui.MainActivity$onCreate$1.onComplete(MainActivity.kt:35)

我的代码在这里:

val appUpdateManager = AppUpdateManagerFactory.create(this)
val appUpdateInfo = appUpdateManager.appUpdateInfo
appUpdateInfo.addOnCompleteListener {
    val result = it.result
    if (result.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                    && result.isUpdateTypeAllowed(AppUpdateType.FLEXIBLE)) {

        info("should show update")
        appUpdateManager.startUpdateFlowForResult(
            result,
            AppUpdateType.FLEXIBLE,
            this,
            1)
    } else {
        info("This is already latest version!")
    }
}

我知道，它就在今天发布.但是有人知道吗?

I know, it is released just nowadays. But somebody knows this?

推荐答案

错误代码记录在 javadoc.

这说:

int ERROR_INSTALL_NOT_ALLOWED

int ERROR_INSTALL_NOT_ALLOWED

由于当前设备状态(例如低电池，磁盘空间不足，...).

The download/install is not allowed, due to the current device state (e.g. low battery, low disk space, ...).

常数值:-6 (0xfffffffa)

Constant Value: -6 (0xfffffffa)

所以我怀疑您的设备没有空间或没有插入电源，并且此设备上的更新首选项需要电源和 WiFi.

So I suspect your device either does not have space or is not plugged in to power, and the update preferences on this device require power and WiFi.
