Android :: Way To Change Map Data For Droid Google Map API
Mar 30, 2010
I need to use a different datasource inside a map in Android than the google provided data. Is there a way to change the datasource to a tile based service (openstreetmap.org for example)?
Or are there other Android map APIs which are OpenSource and can be adapted (except Ericcson Mobile Maps - this doesn't work for me because of the licence)?
It doesn't have to have a server side part - a rich function library would be enough.

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.

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

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.

As many news sources have indicated Verizon is set to eliminate the unlimited data plan in the next month or so.Will this change allow current Verizon customers to get out of their contract without a penalty?Source: http://www.huffingtonpost.com/2010/07/21/verizon-data-plan-changes_n_654481.htmlVia Verizon (Customer Agreement)Can Verizon Wireless Change This Agreement or My Service? We may change prices or any other term of your Service or this agreement at any time,but we'll provide notice first, including written notice if you have Postpay Service. If you use your Service after the change takes effect, that means you're accepting the change. If you're a Postpay customer and a change to your Plan or this agreement has a material adverse effect on you, you can cancel the line of Service that has been affected within 60 days of receiving the notice with no early termination fee.

I cannot for the life of me find any settings for this. I swear I've read about people setting theres to only do it every couple of hours or so to help with battery life but I can't find anything for this. The only thing I've managed to find is an option to set it to only sync over WiFi. Forgive me if this has already been asked but I couldn't find any answers to this dilemma.Oh and also, what exactly is considered "Background Data"? There's an option for enabling/disabling it and I wondered what the term encompasses.

My question is regarding the data sync option, specifically syncing with Google. What exactly (specifically) do background data and auto sync do? I mean if your turn off one and leave the other on, what effect would that have? If they are both off, do the google apps only sync when you open them? Do you have to manually sync the google apps if they are both off? If I was to leave auto sync on, and background data off, would everything still sync in some way? Just looking for some clarification on those 2 options.

My documents show up in the goggle docs app, however when I click it to open the document is blank. This is the case for every document I have. I just checked on my home computer and it's still there, however why doesn't it appear on my phone? I even went to the Google doc website on my phone and every document was blank. I tried restoring w/ titanium and didn't have any luck with that. I tried opening the application and clearing data, however after reassigning my accounts I still had blank documents. The title of all 15 documents shows up, but it's all blank

My husband's Droid was factory-reset by Verizon yesterday, and he lost all of his apps and also forgot his Google login for Marketplace. We set up a new account, but then realized that he can't get his apps back. I figured out his original login, but cannot figure out how to log him out so we can log him back in using his original account.

I am having a weird issue. I have an ArrayAdapter which I am sorting. This displays properly on my screen, however when I check the actual data source, the contents have not been sorted. How can I ensure that sorting my ListAdapter will also sort my data source?
CODE:....
This shows that my data source hasn't been updated, even though my ListAdapter presents my ListView in the correctly sorted order.
For example:
If my data source is [10,9,1,20] after sorting my ListView will show [1,9,10,20] but the data source will still be [10,9,1,20]

I have a program I used on my Hero (Android 1.5) that worked great.. All it did, was the following:
Settings.System.putString(getContentResolver(), Settings.System.DATE_FORMAT, "dd.MM.yyyy");
This does not work on my Nexus One, why? If I call Settings.System.getString(getContentResolver(), Settings.System.DATE_FORMAT); it tells me that the format is "dd.MM.yyyy" but none of the programs displays the date format like that...
What am I missing? Is this not possible with Android 2.1? Or is there a different way?

I am a new to developing for Android and have been reading up and researching in order to become more familiar with the platform. My programming knowledge is moderate I have experience with C++ and a fairly proficient with Actionscript 3.0. I picked up programming primary to work on game development but come from a more artistic/design background.
I have a relatively simple idea for an app that I want to approach from the most practical way possible seeing how it's my first attempt. Essentially the core functionality of the app will be drawing information I will be getting from an ephemeris chart. At a certain time in the day which is based on the data from the chart I want to change an image/display information based on that day. I am trying to wrap my head around the best possible way to do this. Also I would like to give the user an option of having a notification of some kind when the change occurs, but that is something I have come across in terms of basic implementation.
So my question is if you were to approach setting something like this up how would you? What I am not sure about is setting up a time element so the application knows when to change the image/data to display.

I'm using this kind of code for my TCP/IP connection:
sock = new Socket(host, port);
sock.setKeepAlive(true);
din = new DataInputStream(sock.getInputStream());
dout = new DataOutputStream(sock.getOutputStream());
Then, in separate thread I'm checking din.available() bytes to see if there are some incoming packets to read. The problem is, that if a packet bigger than 2048 bytes arrives, the din.available() returns 2048 anyway. Just like there was a 2048 internal buffer. I can't read those 2048 bytes when I know it's not the full packet my application is waiting for. If I don't read it however - it'll all stuck at 2048 bytes and never receive more. Can I enlarge the buffer size of DataInputStream somehow? Socket receive buffer is 16384 as returned by sock.getReceiveBufferSize() so it's not the socket limiting me to 2048 bytes. If there is no way to increase the DataInputStream buffer size - I guess the only way is to declare my own buffer and read everything from DataInputStream to that buffer?

When adding new contacts to the droid x, it added it as both a goggle contact and phone contact. (i only have one goggle account setup). I went into contacts -> menu -> more -> settings. I am UNABLE to check/unchecked the "Phone Contacts" (it is always checked). The goggle one i am able to check/unchecked. WHY and HOW can i toggle the phone contact? Also, backup assistant only takes PHONE contacts and not GOOGLE contacts...while g mail contact sync only takes goggle contacts and NOT PHONE contacts. How can one change phone contact to goggle contact? (i have seen posts all over but no answers...and just replies saying "i have the same problem") I am trying NOT to have two (2) different types of contacts. PHONE and GOOGLE. I just want goggle contacts ( or phone contacts. so i can at least use verizon's backup assistant.

The backup/restore function in android says that the data is saved to your Google account.
I know where the contacts are stored they can be found from accounts.
What I want to know is how to access everything else?
It says app data and wifi passwords etc etc. If I wanted to delete all of this data and start again is the point I'm trying to achieve.
