Cordova / Phonegap下载大量图像，尽可能最佳的解决方案 [英] Cordova / Phonegap downloading a lot of images, best possible solution

问题描述

我需要一些建议。
我有使用Ionic框架创建的Phonegap / Cordova内容应用程序。
这个应用程序可以在线和线上工作。

到目前为止，我设法实现了脱机数据库（SQLite），但是我对图像有些麻烦。

我选择的第一个策略是在应用程序第一次启动开始时安装所有图像（同时进度条可见）

它的工作原理，但我认为应用程序的第一次启动太慢了（超过800张图像）
需要超过7分钟，这对用户体验来说真的很糟糕。 / p>

以下是我的一些策略：

• 下载所有图片作为单个ZIP文件并将其解压缩到设备中




• 仅下载部分图像（25％？），然后在后台下载其余部分，而用户可以使用他的应用程序在某些地方使用某种图像占位符？

哪种策略是最好的？
也许有人有类似的经历？

I need some advice. I have Phonegap / Cordova content app created using Ionic Framework. This app is supose to work both offline and online.

So far I managed to implement offline database (SQLite), but I have some trouble with images.

The first strategy I chose was to "install" all the images at the beginning of first start of app (in meanwhile Progress Bar was visible)

It works, but I think that first start of app is simply too slow (it's over 800 images) It takes more than 7 minutes, which is really bad for user experience.

Here are some of my strategies:

• Download all the images as single ZIP file and extract it into device

• Download only some part of images (25% ?) and then download rest of them in the background, while user can use his app. Use some kind of images placeholder at some places ?

Which strategy is the best ? Maybe someone has similar experience ?
