暂存应用程序.... 解析包时出现问题 [英] Staging app.... There was a problem parsing the package

问题描述

我制作了一个应用 Ave，它通过我的网站下载 ave.apk 包进行更新.该应用程序允许从未知来源安装.多年来，它一直运行良好.

I made an app Ave that updates through my website downloading a ave.apk package. Install from unknown sources is allowed for the app. It has been working great for years.

更新过程在 Android 4.4 和 Andoid 9 中仍然可以完美运行.但在 Android 11 中，在下载新的 ave.apk 后，我收到一个错误，并有两个弹出窗口.下面有一个进度条:

The update process still work perfectly in Android 4.4 and Andoid 9. But in Android 11, after downloading the new ave.apk, I get an error, with two popups. One below with a progress saying:

**Unknown**
Staging app...
____________________________

并为它干杯说:

   There was a problem parsing the package.

                    OK.

但是，我可以通过 Android Studio 和 adb install ave.apk 正常安装 ave.apk.即使是应用本身，只要我不将apk保存在应用文件夹中即可！

Yet, I can install the ave.apk normally through Android Studio and also by adb install ave.apk. Even with the app itself, as long as I don't save the apk in the app folder!

我在 Android Studio 控制台中看到此错误:

I see this error in Android Studio console:

所以好像有些文件消失了??哪一个?显示两个弹出窗口后，我仍然可以执行

So it seems some file has vanished?? Which one? With the two popups being shown, I can still do a

ls /storage/58ED-1620/Android/data/com.floritfoto.apps.ave/ornitologia/Downloads/ave.apk

和 ave.apk 就在那里.因此，丢失的不是 ave.apk.不幸的是，Android 没有告诉我找不到哪个文件...

and ave.apk is there. So it is not the ave.apk that is missing. Unfortunately, Android does not tell me WHICH file is not found...

这是我从文件提供者那里得到的 URI:

This is the URI that I get from the file provider:

content://com.floritfoto.apps.ave.provider/root/storage/58ED-1620/Android/data/com.floritfoto.apps.ave/ornitologia/Downloads/ave.apk

这是我的xml路径文件的内容:

This is the content of my xml path file:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external_files"
        path="." />
    <root-path
        name="root"
        path="." />
</paths>

如果我将 apk 保存到内部存储器或 SD 卡中的任何其他位置，我可以更新.所以这与应用程序文件夹有关.

If I save the apk into the internal memory, or anywhere else in the sdcard, I can update. So this is something related to the app folder.

推荐答案

似乎在 Android 11 中我们无法通过 FileProvider 共享外部可移动 micro sdcard 存储中应用程序自己的文件中的文件:技巧 中的提供程序路径 .xml 文件不再适用于自己的应用程序文件夹.但是，它仍然适用于可移动存储中的其他文件夹(除了 Android/data 和 Android/obb 中的文件夹).如果您认为这是无稽之谈，那就怪 Google.

It seems that in Android 11 we cannot share files from the app own files in the external removable micro sdcard storage through FileProvider: the trick <root-path name="root" path="." /> in the provider paths .xml file does not work anymore for the own app folder. Yet, it still works for the other folders in the removable storage (besides the ones in Android/data and Android/obb). If you think this is nonsense, blame Google.

所以我的懦夫解决方案是将 .apk 下载到公共 Download 文件夹 Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) 中，然后从那里安装.这当然有效.

So my coward solution was to download the .apk into the public Download folder Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), and install from there. Of course this works.
