Android :: Sync And Map - Show Map Path Only Between Two Points - Src - Dest
Nov 24, 2010
I have just started with android ...
I have to develop an android application which should sync with data on webserver..
User adds some data using website, then data should be pulled and synced with data on android device...
I am not sure how to implement this...
Also I have to show map path only between two points (src,dest).. I have googled and it lloks like there is no built-in... only way is to use overlays and draw method.. is my understanding correct?

Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

Do anybody know how to draw path between two points on Map?
I need to draw a line, from one point to other...
I found one link (http://csie-tw.blogspot.com/2009/06/android-driving- direction-route-path.html) about this, but itīs not works well.

I am writing a application that needs to draw a "route" comprised of lots of GPS points (long+lat). The points are close together and don't follow roads, simply drawing a line between each point is ideal.
The current implementation I have is very slow as I am looping over all the GPS coordinates and creating a new Point and overlayitem in an itemized overlay. This takes around 20 seconds for it to load all of these points and draw them to the mapview. Is there a way in which I can construct a series of lines or point from the GPS coordinates and draw them onto the mapview?
Example of current implementation:
CODE:...................

I moved from Galaxy S4 to Galaxy Note 2.
Everytime I take a new phone, during initial setup it gives me to restore my settings from Google which when I enable I get all my saved wifi-access points.
This time however by mistake I didn't allow Google to restore that data in my Note 2 so now I haven't got any saved WiFi passwords.
I had backup of all user and system data from S4 via titanium backup and I tried to restore WiFi access points in Note2 which wont work (maybe compatibility or something, I don't know)
how can i re-enable or force a re-sync that Google to restore my WiFi access points to my mobile or what can i do to get all my saved WiFi profiles back.

I use Contacts GroupU to allow me to send a group email, but I notice that changes I make on the desktop to the groups don't show up on the app. Is there a way to sync the two together after the initial setup?

HTC One, gCal synced to iCal (OSX Lion) with no issues. All dates show on either calendar.
However, neither gCal nor aCalendar on the HTC show dates before August when I bought the phone.
I removed my google acct completely. Restarted the phone and re-entered the google acct. No change.
It seems out of the 5 calendars I use, only one shows all older dates prior to Aug '13. 3 Other calendars show all older dates Oct '11 to present. And the primary calendar doesn't show prior to Aug '13.

This is a picture of my Gmail account on my phone. It doesn't show me anything about contacts, mail, calendar etc.
I made an account on my wife's phone and everything shows up. I made an account for my wife on my phone and it shows no syncs available. So I know it's not an account problem, rather a software problem?
Below is a picture I downloaded online and it shows all the options:
Android 4.2.2
Generic china phone (so is Wife's)

For some reason lately if I delete or show a email as read it doesn't sync that to my online gmail. There has been times when it shows 4 unread emails on the phone (even though everything is read) and when I log into gmail it shows the 4 unread emails even if it was ones I deleted. I tried clearing data from settings>Applications>manage applications>gmail. I have tried refreshing it and manually syncing it and it

I understand the notion of overlays and all, but what if I want to display thousands of points on a map?The map becomes unresponsive after a few hundred OverlayItems are added.What's the best approach for doing this?

I am trying to write a code about catch lat. and long. points with the GPS, actually I am using the shell with the commands "geo fix" because the DDMS doesn't work in linux apparently, I am using this scripts:
getBestProvider(criteria, true); getLastKnownLocation(provider); requestLocationUpdates(provider, 2000, 10, locationListener);
The questions is: the program is working right now in the emulator, but what about if I move the program to the real cellphone? Is the same? I need think in something else?

I want to make a apps that check what's the nearest place from where the user is. I can easily get the location of the user and I have a list of places with latitude and longitude. What would be the best way to know the nearest place of the list against the current position. I could not find anything in the google APIs. I am worried I need to resort to my calculate and have to do math to calculate it.

I am just a beginner in the Android and was experimenting with HTTP.I have published the result of my experimentation through the following link http://kausikdas.webs.com/apps/blog/show/1489440-http-in-android. I am yet to get a device but working with the Simulator.I need feedbacks on the possible network problems I should handle. e.g.: 1. Do I need to discover the access points and dial one before connecting? 2. How can I know which services (Data/Data & Voice/Voice/No/Emergency etc.) current network is supporting? 3. Anything more to take care of?

I'm trying to add a label to each of the points on a map that I've created. Setting the "title" and "snippet" values of the OverlayItem don't seem to automatically cause these labels to appear however. I would've thought this would be a pretty simple and common requirement. Am I missing something? Can someone tell me if there's a function that does this?

I'm trying to develop an application which display the locations of contacts on a map (a Msn-like but for geo-localisation). I search to display a route between my own location and a contact location I want to join but I find yet no solution to do this. In the Android API and Maps add-on API I just find classes to display and listen Location, Distance, GeoPoint, etc., but no possibility to display a route between two points. Is it possible or not provided by the API?

Has anyone checked to see if 3 or more points will show up on an Incredible? I'm trying to see if there's hardware/driver/android support for more touch points. Why more touch points? I dunno. It could be cool for something. I read that the physical screen supports 10 but my first tests printing MotionEvent.getPointerCount() only give me 2.

I have some code that uses a network connection. I create a connection by calling openConnection() on a URL object. Is there any documentation that explains how this process works? Which access point is being used? When that access point becomes invalid, will it automatically switch to another accespoint? etc. I would like to use only WiFi access points and otherwise fail even tho 3G or GPRS could be available, is that possible?

I am developing an application on the android platform. The app performs continues WiFi scan and sends information about the list of visible access points to server. However, I need to remove all the Ad Hoc points. The android.net.wifi.ScanResult api does not seem to have any information on "mode" of the network. Is there anyway I can distinguish a given point is Ad Hoc or Master?

I'm making a game for android where I need to draw a lot of points that change position every frame. I use the ndk to get faster processing performance of the math/physics section of the game, so I need to use OpenGL to get the fastest performance. Right now, I make a texture every frame out of an array that holds the colors of every pixel. I am only able to get ~10 frames per second with this method. Is there anyway I could speed this up? ...

I have two devices - HTC Tattoo and Sony Ericsson Xperia X10. One has 145 DPI, the other 245 DPI.
When I specify font size for a TextView in points, like this:
CODE:...................
I get different physical size of text on these two devices. On 245 DPI, the text is barely readable.
Now, "pt" size is supposed to be physical. I.e., in my test, both text blocks should have letters of the same physical height. Which is not the case.

I am building an application reading the signal strength of each available WiFi access point. I've written code like:
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
// Get WiFi status
WifiInfo info = wifi.getConnectionInfo();
textStatus.append(" WiFi Status: " + info.toString());
// List available networks
List<WifiConfiguration> configs = wifi.getConfiguredNetworks();
However, I have two problems:
In debugging, configs only contains one connection. However, I can see that there are several APs available in the system's wifi setting. i.e. configs is an incomplete list. I don't know how to get the signal strength in Wifi Configuration. I am using HTC Hero and Android 1.5.

I have a Samsung Galaxy S, running Froyo. I have an issue with WiFi handover, so I am posting here (in addition to the SGS section) in case this is an Android issue rather than an SGS-specific issue. I have two WiFi Access Points (APs) at home, both using the same SSID, but on different channels.
I expected the SGS to automatically move (handover) from one AP to another based on signal strengths that vary depending on where I am. However, this does not happen. It stays on the AP that it is connected to, even when moving to very poor signal levels. I need to manually trigger this (e.g by disconnecting from the AP). Any configuration or Android app. By the way, I also tried configuring the APs with different SSIDs, but this didn't work either.

I need advice/pointers on how to display on a map multiple points that change somewhat infrequently based on the device's location. Currently, my application already displays in real-time the device's changing location on a map. I can also easily display the location of one of the other points of interest. However, I have not figured out a way to have both displayed on a map at the same time.

If I use getScanResult() I will be able to get the information about different networks but for example if I am in a school where all access points are under network (SSID) "The school". Will getScanResult() filter out other access points than the one it's closest to and only return 1 BSSID for that network?
