In my android application I use this method in "draw" Overlay class for draw route on map. Can someone tell me if this method is good (in terms of performance) for route draw on map or I must to put code in Thread ??
I'm new to android.
public synchronized void draw(Canvas canvas, MapView mapView, boolean shadow) {
if (pointsAndTimes.isEmpty()) {
return;
}
Projection projection = mapView.getProjection();
Paint paint = new Paint();
paint.setARGB(250, 255, 0, 0);.............

I'm working on a project to display a route in a MapView based on current location from GPS Provider. I'm able to draw the path between two points but the problem starts when the location changes to a new point causing the draw path to erase. Basically my Location Listener saves the current Geopoint and sets the new Geopoint location and after that it starts the overlay to draw a path based on those two points. I think an option could be saving the coordinates to a database and then pulling the information from there to draw the path.
private class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
Toast.makeText(getBaseContext(), "Tracking device..",
Toast.LENGTH_SHORT).show();
[code]....

I made the switch to Google Navigation after using Sprint's Navigation application for a few years on my previous BlackBerry and love it! It's my primary GPS application. So, here's my query. While I was tinkering with it today, I noticed the option to choose an alternate route. We are going to be driving to LA a little later this evening and the default route Google Navigation chose was longer in both time and distance compared to one of the alternate routes (total of three routes). The default route gave said it is 332 miles and 6hr/9min. When I pulled up alternate routes, the second option was 325 miles and 5hr/49min. The third route was over 7 hours long. Do you guys know what methodology Google Navigation uses to pick the default route? Why the longer route?

I'm just writing an App for displaying the route between two coords (lat, long) in google maps view. Displaying an single coord (even with a marker) works fine, but how to do this with 2 ones and the route between them? I must admit that I'm quite new to Android and the maps-API.

Is there anyway to store a route or track using the google maps on the g1. I have a garmin that when on automatically stores your route and it can be saved and uploaded to the computer. It seems logical that this would be available on the g1, as it has all the capabilities already available, ie gps and maps. I can't find any mention of it or a way of doing this with existing software. It seems this would make for a very powerful tool if enabled. What about being able to sync routes and tracks with google earth? I have seen the new application "my maps editor" , but it only enables you to manually place lines or shapes.

Been searching for the life of me for an app (or some way in Google Maps) to go to a spot on the map and draw a line down the street along a certain route and store the run to My Maps. Am I missing something?

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?

I was wondering how people navigate with multiple destinations. It seems that Google Navigation doesn't nativity support it. Ultimately, I want to take a route different than the default quickest route to avoid an intersection, and on other GPS's, I would add the detour as a way-point. If this feature isn't available, has anybody found a workaround?

Simple question, did anyone figure out how to program Google Navigation to take quickest, not shortest route? I love Google navigation, but it always trying to push me to drive through the streets instead of freeway even if freeway is nearby.

Looking through the searches I can't seem to find anyone who has asked this question before and maybe this is being addressed with the 2.1 update. When I'm in the Google Maps application and I've entered my start and end point the route it give me is on a toll road or a highway I know to be very slow because of traffic. I know that when I'm using my computer for directions I can drag the line to add a via point / alternate route. Is there a way to do this in the current Google Maps on the HTC Droid Eris?

I was playing with Google Maps after the 2.1 update and on one occasion for a trip a screen came up that listed (3) different routes with the total miles and time for each route. One was for I295, one for I95, and one was for US202. Since then I can't seem to replicate that screen. Any answers? Suggestions? UPDATE: Found the answer. After selecting Navigate for a route, click Menu and a screen will come up with (3) symbols on the bottom. Left most one is the Symbol for Navigate, the symbol with a couple of arrows is the one to PRESS. This will give alternate route info that you can select. UPDATE AGAIN When I tried again, the option I mentioned above was grayed out and no longer works. I'm not sure what is going on.

Most rides I do I can find these maps but cant do anything with them.

Can you make a route on google map on desktop, then send it to the android phone? It is alot easier to do it, rather on the map.

Before I updated to android 2.2 and updated to latest Googlemaps the navigation was perfect. It calculated the route in seconds and was a joy to use. Since the updates, it is taking ages to calculate route, so long in fact that I exit the programme and start again, and then I just give up and dig out my atlas.

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. Do I need to use overlays? If so do I have to override the onDraw() method of the overlay and draw a line here? I actually tried these things but with no result.

Dear Android community, i've a license/legal question regarding asking Google directions to be drawn directly into the MapView. Some of you know that asking google http://maps.google.com/maps/nav will give directions in Json + a Polyline encoded form.What i would like to know is, where is the Terms of Service regarding this functionality? It is for Google internal use or not? There's also the KML which gives similar informations. Please note that it is NOT for real time driving directions but a path to be drawn from a point to another and your position NOT refreshed in real time and of course it is for an app downloadable free of charge.

Frustrating - but apparently the capability is I can customize a route online with Google Maps, save it to my maps and send it to the phone but it sends the static map.Ridiculously, all this power and I can't take those directions from the PC and turn them into turn by turn directions on the phone.

I'm writing an app that shows in google maps pipes and valves(lines and points). For that i've two classes.
One extends from ItemizedOverlay, and i add to map overlay one for each category of valve, and each one can have more than one item.
The second extends from Overlay, and in the draw method y draw the line with the method drawline of the canvas.
The problem i've is that the lines are drawn over the ItemizedOverlay items, no matter the order i add them to the mapView.getOverlays().
I want the lines on the bottom of all overlays. is there a way to do that.

right so the bottom buttons were working fine, but the next day, the back button takes me to the home screen :S so if im on facebook, press the back button, instead of going to the previous page. and i also set up the draw thing to unlock it, but as it was raining a little it said i entered it wrong too many times and asked for the google mail thing... but i really have no rememberence of making one, which is so ******* annyoying.
the only way ive found out to solve this problem is doin a phone software update, however as my bottom right button is working properly, everytime i hold it down to plug the phones usb, the phone just starts normally, so basically i cannot do the system update.

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?

I'm trying to play a music (using MediaPlayer) during a call and want the caller to hear the music I'm playing. Unluckily it doesn't seem work at all, the caller hear nothing even I set the music volumn to MAX ( of course, the speaker and the mic on Android are far away from each other). Is there any ways to route Android's audio output to its Mic? Or something like "Stereo Mix" in Windows?

I currently have a moto droid, and am thinking about getting a android tablet when they mature a bit. My concern is i want to use this at work, but for this to be completly functional i need to put a static route into the system. We have a wireless network which is seperate from our wired by a router. It is all static IP based and so on to keep employess off the internet, but if you know what static route to put in you can access the systems on the wired network. Does anyone know if this is posible, i have tried looking at the system files via Astro and i havent found anything.
