应用内更新提供InstallException(ERROR_API_NOT_AVAILABLE) [英] In-App Update gives InstallException (ERROR_API_NOT_AVAILABLE)

问题描述

使用以下代码段实现了应用内更新功能:

Implemented in-app update feature, using the following code snippet:

private void showInAppUpdateDialog(boolean isMandatoryUpdate) {
    Task<AppUpdateInfo> appUpdateInfoTask = appUpdateManager.getAppUpdateInfo();

    appUpdateInfoTask.addOnSuccessListener(appUpdateInfo -> {
        if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                || appUpdateInfo.updateAvailability() == UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {

            int appUpdateType = isMandatoryUpdate ? IMMEDIATE : AppUpdateType.FLEXIBLE;
            int requestCode = isMandatoryUpdate ? REQUEST_APP_UPDATE_IMMEDIATE : REQUEST_APP_UPDATE_FLEXIBLE;

            if (appUpdateInfo.isUpdateTypeAllowed(appUpdateType)) {
                // start the app update
                try {
                    appUpdateManager.startUpdateFlowForResult(appUpdateInfo, appUpdateType, targetActivity, requestCode);
                } catch (IntentSender.SendIntentException e) {
                    e.printStackTrace();
                }
            }
        }
    }).addOnFailureListener(e -> {
        e.printStackTrace();
    });
}

我正在具有Android 9的设备上测试应用程序内更新.不过，它仍然给我以下错误消息(ERROR_API_NOT_AVAILABLE):

I am testing in-app update on the device which has Android 9. Still, it is giving me following an error (ERROR_API_NOT_AVAILABLE):

com.google.android.play.core.install.InstallException: Install Error(-3): The API is not available on this device. (https://developer.android.com/reference/com/google/android/play/core/install/model/InstallErrorCode#ERROR_API_NOT_AVAILABLE)
        at com.google.android.play.core.appupdate.i.a(Unknown Source:24)
        at com.google.android.play.core.internal.o.a(Unknown Source:13)
        at com.google.android.play.core.internal.j.onTransact(Unknown Source:22)
        at android.os.Binder.execTransact(Binder.java:731)

是说，请检查以下链接: https://developer.android.com/reference/com/google/android/play/core/install/model/InstallErrorCode#ERROR_API_NOT_AVAILABLE )

It is saying that check the following link: https://developer.android.com/reference/com/google/android/play/core/install/model/InstallErrorCode#ERROR_API_NOT_AVAILABLE)

使用Play核心库版本:1.6.5

Using Play core library version: 1.6.5

最新的核心库版本:

implementation 'com.google.android.play:core:1.7.0'

但是，我不知道为什么说ERROR_API_NOT_AVAILABLE.任何帮助将不胜感激！

However, I am not able to get why it is saying that ERROR_API_NOT_AVAILABLE. Any help would be appreciated!

推荐答案

首先，请检查您是否正在使用最新版本的播放库.

Firstly, please check that you are using the latest version of the play library.

其次，轻描淡写的事实:请检查您要测试的应用具有与Play商店中可用的包名称相同的包名称.

Secondly, understated fact: Please check the app you are testing has the same package name which is available on the play store.

示例:

您在Play商店中有一个应用程序，其程序包名为 com.example.app ，但是您正在测试该应用程序的程序包名为 com.example.app.debug .您将收到以下错误: ERROR_API_NOT_AVAILABLE

You have an app on the play store with package name com.example.app but you are testing your app with package name com.example.app.debug. You will get this error: ERROR_API_NOT_AVAILABLE

注意:测试时，您需要在Play商店上拥有至少一个版本的应用.

Note: You need to have at least one version of your app on the play store when you are testing.
