Android :: Draw Path On MapView From Large Amount Of Longitude/latitude Points

Aug 2, 2010

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'v been busy for a long long long time finding out how to draw a line between two (gps) points on the map in HelloMapView but with no luck.Could anyone please tell me how to do so.Suppose I use the HelloMapView which extends MapView.

Android :: Catching Points With GPS - Geo Fix

May 5, 2009

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?

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?

Android :: Adding Labels To Points On Map?

Jan 6, 2010

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?

Android :: Displaying Route Between Two Points On Map

Dec 6, 2009

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?

Android :: Support For More Touch Points?

May 23, 2010

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.

Android :: Network Connections / Access Points

Jul 16, 2010

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?

Android : Physical Size Of Font In Points

Aug 3, 2010

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.

Android :: Signal Strength Of Each WiFi Access Points?

Aug 9, 2010

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.

Android :: No Automatic WiFi Handover Between Access Points

Nov 16, 2010

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.

Android :: Multiple Points On Map Changing Frequently On Location

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.
