android - Google Play 用户安装问题

Question

我的 Rhonna Designs 应用最近在 Google Play 上获得了很多一星评价。有没有其他人处理过用户安装错误？如果是这样，我该怎么做才能解决它？我希望这是我正在做的事情，并且 Google 的基础架构没有看起来那么糟糕。

以下是我获得的几颗星:

How on earth can it "not install in the place attempted" ??? Someone please help me install it :( I wasted my money :(

I purchased it and couldn't install it by the error called 961 I just don't get it what a waste of money

I paid for this app and was very excited, but it won't install and just says "error 918". Such a waste of money.

1. 评论“未在尝试的位置安装”和“error 961”指出内存不足的问题。我猜是内部存储器。

2. 您的应用程序非常大 - 44 MB。让它尽可能小，例如你可以compress PNG。如果你不能压缩更多，做一个真正的“瘦客户端”并下载内容。制作一个几 MB 的“安装程序”，其中将包含所有难以跳过的内容(代码、布局等)，并在第一次从 www.some 的服务启动时将其余内容下载到 SD 卡(图像等) .url.com/content/1142avrh34h34。向用户显示适当的进度条。

3. 看一下apk安装process .首先，apk 下载到/data/local，在内部存储。你无法改变这一点。因此，如果用户内存不足并且他下载并解压缩了您的 44 MB apk - 就会发生不好的事情。这就是导致您出现问题的原因。

4. 将 android:installLocation="auto" 更改为 android:installLocation="preferExternal"。下载后至少会在SD卡上存储一个apk，节省一些内存空间。通常外存的可用内存比内存大得多。来自 App Install Location :

   If you declare "preferExternal", you request that your application be installed on the external storage, but the system does not guarantee that your application will be installed on the external storage. If the external storage is full, the system will install it on the internal storage. The user can also move your application between the two locations.

   If you declare "auto", you indicate that your application may be installed on the external storage, but you don't have a preference of install location. The system will decide where to install your application based on several factors. The user can also move your application between the two locations.
