Android - How to improve osmdroid offline map performance in term of reponse time

由 旧时模样 提交于 2019-12-11 14:38:23
问题 Now, I'm using my offline map osmdroid MapQuest (.zip file). However, the delay action time is not very good. Like: Map View Initialiation Time, Action Zoom Time ... Are there some solution to improve its performance? (like unzip .zip file or something else?) Thanks. 回答1: You stand a lot better chance with something like the GEMF format that is explicitly designed for the job at hand rather than ZIP. For big files it's way better. It is what I recommend for my users. 来源： https://stackoverflow

How to run or link an OnEdit standalone trigger in a google spreadsheet

由 ↘锁芯ラ 提交于 2019-12-11 10:11:23
问题 I'm developing new applications in google. I have a function that is running without any problem if it's bound in the spreadsheet but when it is offline it doesn't work. That's why I saved this script in google drive in order to be called from my google spreadsheet even if it's offline. I don't know how I link this function to my spreadsheet in order to run both offline. function onEdit(event) { var DistSheet = event.source.getActiveSheet(); ... } 回答1: If you want to use a simple trigger like

Check if offline application cache disabled by browser

由 我只是一个虾纸丫 提交于 2019-12-11 09:56:36
问题 So I've got an application that stores offline data using an ApplicationCache. Long story short, it's silently dying for users who don't have offline data enabled, most commonly because they've got history turned off or are using private browsing, and I'd like to catch this and give the user a clear error. It appears that this can be detected by checking the cache's state, which will return 0 UNCACHED when there is no cache... but I'm not sure if that means that there is no cache yet , or

How to write an offline version of an AJAX/ASP.NET web application

由 泄露秘密 提交于 2019-12-11 06:16:31
问题 We have a web application that uses AJAX to talk to an ASP.NET web service. We would like to write another version that can be used offline. We need to be able to re-use our existing code as much as possible. What approaches should we consider? The app is currently using XmlHttpRequest to get dynamic data from the server. Obviously the offline version will not be able to talk to the server, but it does need to talk to something! I'm sure installing IIS or Cassini on the client would work, but

using firebase on offline networks

由 痞子三分冷 提交于 2019-12-11 06:13:36
问题 I have a intranet network of 50 computers without an internet connection; is it possible to use firebase to share data across these computers - for example, a chat program? My limited knowledge in this field hints that this should be possible if the firebase api was downloaded to the local network and referenced with local expressions rather than web links - is this possible? Thank you Greg 回答1: Firebase is a cloud service where all data is loaded from and synced back to the cloud. Currently

Couchdb online offline synchronisation

由 南笙酒味 提交于 2019-12-11 04:53:49
问题 I'm building a .NET application which will have a local CouchDB instance where all data is written to, and a central CouchDB where the local CouchDB is synchronised to. The difficulty is that there will be multiple clients which will synchronise with the database at different points (and could edit existing data, creating conflicts). The internet connection will not be consistent, so consequently the majority of data will be created/ edited while offline. I believe that CouchDB handles this

Embedded HTML 5 video is stored in the cache but is not displayed on iPad 2

由 徘徊边缘 提交于 2019-12-10 18:45:10
问题 I am creating an offline webapp for the iPad 2, which includes video content. When the page first loads, the video displays fine. But when I reload the page, the video's play button becomes broken. I've gone into Settings > Safari > Advanced > Website Data and, sure enough, the video is in the cache... So the problem seems to be that it is not being retrieved from the cache. My HTML code snippet: <html manifest="cache.manifest"> ... <video width="320" height="240" controls="controls"> <source

web forms application storing data offline using sqlite

由 不打扰是莪最后的温柔 提交于 2019-12-10 10:14:31
问题 I have an asp.net web forms application that uses a sql server 2005 on a remote server. All controls are bound using linq to sql. I am trying to provide full offline functionality, so I was wondering if I could create an sqlite database just like the sql server db, install it on users device and then when connection is lost or user wants to work offline, I change binding to the sqlite database? I imagine I would download all user information to the sqlite db when the user first logs in and

Subversion Proxy for working offline?

由 痞子三分冷 提交于 2019-12-10 09:57:11
问题 What is the best approach for working at a customers site (with several people) where there maybe not internet access the whole time and using a subversion repository? (Migrating to Git or Mercurial is out of the question at the moment) But wouldn't it be possible to leverage something like, for instance the Git SVN Integration, to create a proxy which acts like a subversion repository for the clients and may be used at the end to synchronize the changes back to subversion? Is there already
