can you advice me a book or something else containing good practices about how to build/structure a web application in a way that will be easy to extend it with an Android/iPhone version later.I am currently trying to get into Django so it will be nice if the practices are related to it.

Are there any guidelines where should my app store resource files downloaded from Internet?
View 3 Replies View RelatedWhat are the best practices people have used to integrate help/tips in their application? One way I can think of is having html snippets in resources or assets - perhaps as html files - maybe as formatted strings. However, I think it would break down once an html file linked to another html file or an image or icon. I'm sure some of you have apps that are so wonderfully intuitive that they don't need any help. And I admire that. But I'm not making that assumption for my app.

- How to manage version conflicts?
- What to do with databases?
- Can you make appear a message with "what's new" if it's an update, but nothing it's a new installation?
- Should you backup old data before updating, and how?
- Did you run into any trouble and how did you solve it?
- Can update be partial (like, just a patch)?
What is the best way to release two versions of an application? E.g. a free version with limited features, and a paid version with the full feature set. #ifdef would be the ideal way to do this, but Java doesn't support it. Could I do something like: try {import com.foo.myapplication.ExtraFeatures; } catch (Exception e) { // ignore it, this must be the free version}? I could manage with this kind of construct, although #ifdef really would be ideal.

Necessary features include: support for multiple memos, quick access to view and edit multiple memos, ability to organize memos into categories or with tags, ability to search through all memos at once, ability to synchronize memos with desktop and/or the cloud. This poll is designed to show potential developers that there is a market for such an app.

We have a web application and we've built phone applications (iPhone, Android, BlackBerry) to be companions to the site. The usual workflow is that an existing user of the site gets a phone app and then plugs their existing credentials into the phone app and they are off and running, but more often now we are seeing folks who are downloading the app and then (and this should not surprise anyone) don't read the help screen that explains they need to go and get credentials at the web site and therefore cannot connect to the application which does require registration to manage their content. This is a giant usability fail condition.
So we know that we need to put user registration workflows on the phone app. Other than the obvious solution of duplicating our registration page on the mobile, does anyone know of a better identity solution for the phone? For example, on the desktop we also use Facebook Connect as an identity server and the users love it. I'm looking for something that simple that we can implement across the major smartphone platforms.
Clarifying note: I should add here that this registration mechanism is likely to; and it would be desirable if it did, go hand in hand with a general identity/authorization mechanism such as the Facebook mechanism mentioned below. One other place I'm poking around is to see whether there's an openId solution that does not require a browser to pop up.

I'm thinking of things like pushpins, scope sights, house, car, shop, and other small graphics you might overlay on a map or picture.
Most people just rip them off from the web, but I'm looking for an honest source.
A while ago, I found a website marketplace where you could commission stuff from graphic artists. Does anyone have any links for these? The sort of thing I mean is like this: http://www.graphicster.com/Default.aspx (But those guys haven't got critical mass yet). Or these guys http://www.crowdspring.com/how-it-works/ (but they seem a bit high end).
I'm making an ecommerce application on Android and, as it is my first serious project, I'm trying to figure out beforehand the best approach to do this.The application talks to a web service (magento api, meaning soap or xml rpc unfortunately) and gets all the content on the phone (product categories, product details, user credentials etc.). I think it should do lazy loading or something like that.
So, I was thinking to keep the user credentials in a custom Object which will be kept in a SharedPreferences so that every Activity cand easily access it. I'll use a couple of ListViews to show the content and AsyncTask to fetch the data needed. Should I keep all the data in memory in objects or should I use some sort of cache or a local database? Also, I'm planning to use a HashMap with SoftReferences to hold the bitmaps I am downloading. But wouldn't this eat a lot of memory?How cand all the activities have access to all these objects (ecommerce basket etc.)? I'm thinking of passing them using Intents but this doesn't seem right to me. Can SharedPreferences be used for a lot of objects and are there any concurrency issues?
Any pointers would be really appreciated. What are some good guidelines? What classes should I look into? Do you know of any resources on the Internet for me to check out?

View 1 Replies View RelatedI am trying to learn how to do stuff in Android, and I'm not sure of the best way to build the interface.I've been working on porting an iPhone app, which uses navigation controllers and table views for looking at the different sections: basically, someone touches a cell in the table, which drills down to another table. when they touch a cell on that table it drills down to a webview that displays the information.I want to do something similar for the android app, but I don't know how, or if there is a better way native to Android. I've figured out how to use the webview to my purposes, but moving forward and backward in the table tree is unclear.

My company is in the process of evaluating if we can add support for Android to our product. I am currently working on porting our existing J2ME library to the Android framework and I have a question regarding our UI component. Right now, we have a custom menu that we allow our developers to bring up on the device. On J2ME, we simply have a single call that the developer makes to enter into the menu and then we handle the rest. On Android, it seems the best way to handle this is an Activity. But I have a few questions regarding this approach including is the really the best way to do something like this? Second, if it is, if there are multiple applications on the device that are using our library, are there going to be conflicts with them all having the same Activity embedded in them? Is it possible to create an Actvity at runtime and use it directly? Would there be any side effects of going about it this way?
View 2 Replies View RelatedI have to create a number of tables for caching some amount of textual data, obtained by reading XMLs. These tables need to be created only once - on the initial run of the application. The data in the tables should be cleared after fixed time period. There should be a class exposed to other classes that would allow CRUD operations on this database. Googling found me some links to tutorials for creating databases and Data Access logic.
I have some questions, please help:
How many DataBaseHelper(DBAdapter) classes should I have, I am guessing only one? Is it okay to have all the SQL DDL and DML statements, DB name, Table Names as static strings of this class?
How do I ensure that the tables are created only once?
Is it possible to clear the DataBase after a fixed time interval?
Are there any best practices to be followed when designing the database?
The data in the database is to be displayed in Lists. I have data in ArrayLists(created when parsing XML) as well as Database(after these lists are persisted). What adapter should I use to back the list up? Should I use ListAdapter or CursorAdapter?

View 8 Replies View RelatedUnderstanding how to declare activities in the manifest file, how to set the appropriate flags when starting them through intents, is quite challenging in all but the default cases. The combination of all these settings and flags is daunting. I've been developing for Android for over a year now, have read the application fundamentals and the reference guide for 'Intent' quite a few times and still I don't have a good grasp of which manifest settings or intent-flags should be used for starting activities in many situations (workflows). Is there some source/document that can explain certain work-flows (ways of navigation through activities and tasks), that shows examples of how to configure and start activities?
