Android :: Loading Google Maps Data Into Searchable Data Structure

Mar 2, 2010

For my CS bachelors I am doing a Senior project using android and google maps.My vision was to do a (relatively) simple Dijkstra shortest path using google maps road data. I was going to add elevation change along with 2D distance. I am doing well playing with maps in android but I am completely stumped trying to access google maps data in any sort of searchable form.How would I go about accessing the data for say intersections of roads (lat/long) in a particular area?There has to be a way to pull that data in some sort of tree form. It seems like it may be possible with kml?Any pointers would be awesome.I want my paths to follow roads but If i cant this is going to turn into an orienteering application fairly fast.

Android :: Advice On First Application (loading Data / Populating Data)

Jun 23, 2010

to start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.

But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.

Android :: Google Maps Navigation Without Data Connection

Sep 20, 2010

I use HTC Desire (updated to Froyo) and at home Google Maps Navigation works great and I never worry about the data connection because I have a large data allowance each month. But I'm now in Germany for a few days and I don't really want to pay roaming rates. So, I find that I can of course use the hotel wifi to plot the route.

This can work but most of the time it doesn't. The problem is that the route is not downloaded (at least not completely) until the phone has a GPS fix. Usually this happens after I'm out of range of the wifi signal and so I have no route to navigate. Is there a way of downloading the route without needing the satellite fix to validate it? This would make life so much simpler!

Android :: Building Outline Data In Google Maps

Jun 10, 2010

I'm working on an Android project that focuses on knowing how close you are to buildings. I wanted to know if there is some way to extract the geographic information about the outlines of buildings out of the Google Maps API. The functionality I'm looking for is similar to what's going on in this app. (Click the link near the top of the page that says "View Live Sample".)

Android :: Searchable Calendar That Import 10 Years Of Outlook Data

Sep 25, 2010

I recently bought a DroidX and am looking to import 10 years of Outlook calendar info. I don't need to do a two-way synch as I am using Touchdown for Exchange synchronization and it works great (but it is not good with large calendar history files). I just need a stand-alone calendar app that has it's own data file and can import my Outlook calendar history and allow me to search.

HTC Desire :: Google Maps 3G Data Usage

Jun 1, 2010

My phone seemed to be using a lot of my months quota of data without me actually doing anything. I thought it may have something to do with google collecting location data in the background so turned off 'use wireless networks' in location settings. This seems to have fixed the problem but is there a way of having this setting enabled so the phone only uses 3G when in an application rather than using my data usage without being in any particular program?

HTC Aria :: Google Maps / Navigation Data Usage Rate?

Jul 4, 2010

Does anyone know how much data Google Maps & Navigation uses? Obviously this can change depending on how far you are going and what type of map detail you are using, but I was just wondering. Is it hundreds of MBs for each trip around the block, or something much smaller? With AT&T's tiered data plans, this is important to know.

Android :: Creating Static Data Structure On Application Startup For Android

Oct 27, 2010

In my application, I am going to create a few listviews that are dependent on the listview before it. For example,Then, depending on user choice, will go next screen, let's say, it contains a submenu of each type of school,that may be different or may be the same to other states.What I want to know, is how to populate these different lists dynamically as the user goes on? I don't know what the best of doing this is, and I seem to be looking in the all the wrong places because I keep getting stuck. Once all the data is added into whatever structure is used, it will be static. I basically just need help as to how to code information into some sort of hashtable or anything of the sort that can be easily referenced, and later when the Application is updated, be able to add more schools/states/submenus etc.

Android :: Google Maps Application - Tiles Not Loading

Jun 29, 2009

For some reason I cannot get my first maps application to work. I have gone though the full process of getting the MD5 fingerprint for the debug.keystore, registered for the key on the website, put it into the xml file. Even had changed my computer's locale to US English. I also signed the application with my private key and pushed it via ADB to the emulator. All attempts so far resulted only in the grey Google Maps background with the tiles not loading. JAVA_HOME environment variable points to my JDK file. Not sure what else I can do. Even upgraded from SDK 1.1 to 1.5. No improvement. I am really stuck here. I am running WIN XP, Eclipse ganymede, SDK 1.5 r2, with the latest ADT. Here is my class file code: package com.mellagio.maps; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import android.app.Activity; import android.os.

Android :: Data Structure Used For SMS Messages In Android

Does anybody know what data structures are used to the store messages in an SMS client app, and whether there is an existing API for this.I was perhaps looking at implementing a link list for the purpose but if the work has already been done in an API then perhaps it would be unnecessary to commit time to the task that could be spent programming other parts.

Android :: Loading Route Directions In Google Maps From PC To Phone

Aug 7, 2010

Is it possible to move routes/directions from Google maps on your PC web browser to maps and navigation on your phone?

I have worked out how to export kml files from Google Maps on the PC.

It would have been nice to be able to save routes in My Maps (maybe you can, but I don't see how).

Also, is it possible to build a route with multiple destinations in Google Maps/Navigation on the phone?

Android :: Best Way To Store Application Data / When Data Stored / Data Format Could Change In Future Versions?

Mar 4, 2010

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

Android :: Way Of Loading Data / Notifying An Activity?

Oct 8, 2009

I just tried a stupid approach and it crashed my app... Basically I have an activity that has three tabs (containing three activities). Each of the tabs gets its input from an xml file downloaded off the net. Everything is fine but when I start my app, it has download the xml file and there's a "wait" time for this.I managed to get around this by adding a splash screen. It looks beautiful but the problem is when I click on the second tab, it still has to get the list off the net, so it looks ugly now... It waits before displaying the list. So what I did was design an AsyncTask that just downloads the xml file. In my main activity, I spawn two tasks initially and send the URL and Intent as parameters. And inside the activities that start inside the tabs, I use a wait(). Inside the AsyncTask, after it is done with the download, I notify the Intent using notify(). This crashed! Of course, I didn't expect it to work but just wanted to try :) Writing it so that I can either get a feedback as to why this failed or to prevent others from wasting their time on this...Now, I am sure many face the problem of a "wait" time inside the tabs. How do I solve this? I am thinking of either dimming the screen and then displaying a series of toasts or display a progress indicator inside the tabs or pre-fetching the xml files... I don't have a clue on how these can be achieved.

Android :: Loading New Data With Back Button

Apr 10, 2009

I have a message application so that on view 1 is displayed a list of messages and when you go to view 2 (subactivity) you can send a message. I want the program to work so that when you hit the android back button, you can go back to view 1 and see the list of messages including the new message. Right now only the old data is displayed, and I noticed that displayContent() is not called when going back which I assumed it would. Is there any way to specify that when the back button is hit, to call displayContent() again on the previous activity?

Android :: Loading - Row At The End Of The List - During Data Download

Aug 1, 2010

I have got list that is filled with data from internet.

Datas are downloaded in chunks. At the end of the list next portion of data is downloaded and added to the list.

I'm detecting list end with help of onScrollListner:

CODE:........

I would like to addLoading... row when datas are being downloaded. Something similar to Gmail loading row at the end of the list.

I know that I can hack adapter.getCount() to return size + 1 and force adapter.getView to display loading... at the end of the list.

How can I do that in more elegant way?

Android :: Loading Data Asynchronously While Displaying GUI

Jan 20, 2009

My application needs to load and process some data at the startup which delays the displaying of the GUI quite a bit. I addressed that problem by starting a new thread to load and process the data. It solves the problem nicely, but is there a better way to do asynchronous processing in Android applications that I missed?

Android :: ActivityList - Loading Data From Network Best Practice

Sep 29, 2010

I have multiple ListActivity(s) with a custom ArrayAdapter. I have to load an XML file from the Web, and the user moves to a new activity by selecting a list item.

What is best practice for:

Displaying a loading indication to the user.
Threading the networking stuff so that the user can cancel the loading of the data if need be / move to the previous activity.

Example/source code would be greatly appreciated - I've used http://www.helloandroid.com/tutorials/newsdroid-rss-reader as an introduction, however it doesn't display a loading indication.
