Google Maps Displays Grey Tiles When Drawing Geopoints
Jul 20, 2012
I'm trying to create an app to plot our mountain bike trails on a Google map. I've got the Google map part working. However, once I try to plot a couple of geopoints and connect them it does displays the geopoints and connects them, but the Google map stops displaying. Only grey tiles show. Here is my code before I plot the points which works. import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Style;
import android.graphics.Point;
import android.os.Bundle;
[Code]....
Then I change my code to this to plot and connect a couple of geopoint and it turns map tiles grey.
import java.util.List;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
[Code]....

I followed this guide here perfectly and have gone through it again but when I run the program on my google avd the page loads but only Grey tiles appear and it doesn't show a map which it should.
Does anyone have any ideas?

I created a google maps app. I have been using the debug md5 fingerprint to test my app as I built it. It worked fine. Now that I'm ready to publish, I'm having a problem with the nondebug md5 fingerprint I need to publish with. I'll go step by step with what I've done. I right click my app in eclipse, then go down to android tools > export signed application package. It pops up a window. I see my app name i hit next.
keystore selection> create new> C:AndroidAppMapKey> create passwords for it hit next.
Key creation> create my alias name.
Lets say mapalias> give it the same password as the keystore. Give it a validity of 1000> insert my name. hit next. destination and key/certificate check> C:AndroidAppMyGoogleMaps.apk > hit finished. After that i open up cmd, I'm on windows 7.
I type> keytool -list -v -alias mapalias -keystore C:AndroidAppMapKey -storepass mypass -keypass mypass. It generates the md5 code i need. I go to the website to register the md5 code. get the code i need to use on my android: apiKey="ofhsjfjfjmmmmmdnjjffmmf". Run it on the emulator and my phones. I get a grey screen with no map coming up.

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.

Since the new my apps section on Google play I noticed it shows all the apps I've ever downloaded. Even if I didn't purchase it. Which I thought they always needed.

Is there any way to get the driving time between to geopoints? I want to create an algorithm that calculates the time from the users location to several destinations and then chooses the shortest (by time).

I am able to parse XML using SAX Parser and able to display the points in text view.
But now I want the points to be displayed on the map.The XML Contains tags for latitude and longitude.
I want to read the latitiudes and longitudes and display them on map .

I'm using the latest version of Google Maps on JB 4.2.2 [Nexus 4]..I noticed that I cannot edit the names of my locations in "My Places" in the phone app. So I used Google Bookmarks (google.com/bookmarks) from my PC to edit/rename My Places. However, the names do not sync or carry through to the Google Maps app on the phone. The names in the app are still the generic names, coordinates or street names.
Is there any way to change the names of My Places and get them to sync with the phone app? Really baffling!

Is Google Latitude available in the UK or not, because it doesn't seem to be working for me? I have received the RC9 update for G1 and have Google Maps 3.0. Is there an a Google Latitude application that I should have or do I access everything through Google Maps? When I go the www.google.com/latitude on my G1, it offers me the option of "launching" Latitude but it just takes me to Google Maps. From there, I cannot see the locations of my Google "friends" (who have agreed to show location), neither does my own location show up on the Latitude homepage on the web (I have settings turned to "detect my location automatically").

I have 2 calendars on calendar.google.com and a HTC Hero running android 2.1 with PureGrid calendar & the everybody all the time Agenda Widget. I've had both calendars synchronized to PureGrid & Agenda Widget but just this week the 2nd calendar no longer displays through them though it still exists if I go to calendar.google.com and both calendars can be selected on the list of available calendars for either widget. I'm running the latest version of each widget.

I'll start by saying that I'm REALLY new to OpenGL ES (I started yesterday =), but I do have some Java and other languages experience. I've looked a lot of tutorials, of course Nehe's ones and my work is mainly based on that. As a test, I started creating a "tile generator" in order to create a small Zelda-like game (just moving a dude in a textured square would be awesome So far, I have achieved a working tile generator, I define a char map[][] array to store which tile is on :Code...

In a feeble attempt to learn some Android development am I stuck at graphics. My aim here is pretty simple:Take n small images and build a random image, larger than the screen with possibility to scroll around.Have an animated object move around on it.I have looked at the SDK examples, Lunar Lander especially but there are a few things I utterly fail to wrap my head around. I've got a birds view plan (which in my head seems reasonably sane):How do I merge the tiles into one large image?t each onDraw redraw the background of the previous spot of the moving object, and the moving object at its new location
The problem is the hands on things. I load the small images with "Bitmap img1 = BitmapFactory.decodeResource (res, R.drawable.img1)", but then what? Should I make a canvas and draw the images on it with "canvas.drawBitmap (img1, x, y, null);"? If so how to get a Drawable/Bitmap from that?I'm totally lost here, and would really appreciate some hands on help (I would of course be grateful for general hints as well, but I'm primarily trying to understand the Graphics objects).

public class MapAct extends MapActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } }

I am having some issues getting tiles to load into my MapView in android development. I have searched and looked at similar problems on here but with no luck so far.
I have looked at the instructions here and have got hold of my debug API key. I have entered this into my MapView.
I have checked that my emulator and my debug device have got an internet connection.
I have move my Internet permission tag in my manifest file to be before the application tag.
I don't know what else to check.
I am also unsure of the best way to develop this. It seems that I can't debug with a properly signed app as the debug keystore needs the same password - android. This would imply that each time I go to do a release build I have to change the key - which seems very fragile!
Is there any way of developing and releasing builds with my own generated maps API key?
Some code for you to look at:
Main.xml:
CODE:.......................
AndroidManifest.xml:

I am using a gutted version of the Snake Android sample. Pretty much I am using the TileView class verbatim and am only trying to display a few tiles on the screen. Instead of the SnakeView class I am using a GameView class in which I only included the code I thought necessary to display a tile on the screen.
Here is the class
CODE:...............
Now what is happening is that when the updateWalls() method is called, the tiles are placed within the View and comes up like this:
Now when I uncomment out the updateCellularArray() method and comment out the updateWalls() the program force closes and throws a NullPointerException. After some debugging I figured out that when the updateCellular array method is called, the mTileGrid array in the TileView class is not initialized, but it is when updateWalls() is called. I am completely baffled as to why this is happening. It doesn't matter if i replace the for loop with a simple setTile(GREEN_STAR, 3, 3); it still force closes.
Here is the TileView class I am using (again this is the same one in the Snake sample that comes with the Android SDK):
CODE:.......
simplified GameView class
Alright after modifying the updateCellularArray() method to the following:
CODE:........
It finally placed the tile where I wanted it to...
I'm starting to wonder if it has something to do with the RefreshHandler. Possibly when the RedrawHandler's sleep method is called in the update method of the GameView class. I'm not quite sure how it works so I am going to try playing around with it and see what I can come up with.

Is it possible to determine the coordinates of the tiles that are visible in a MapView, relative to the first tile in the upper left corner of the entire map (including the invisible part)? I can't seem to find a way to get the tile coordinates.

I just bought my nexus 5 and its pretty awesome but i was wondering if i could change a couple of questions...
Do you know the menu which appears when you press the lock button(i think its called power menu), is there a way of changing what icons appear there?
Can the tiles also in quick settings panel be changed?
Finally, if you press the middle button you see the google logo to laung google search, can that be changed to show other apps?

The Maps API always had its issues... since updating my Nexus One to 2.2.1 FRG83D earlier today, I see a problem more serious than anything prior. This applies to both Google Maps and (any) app that uses the Maps API (that I have tested). It's pretty obvious and simple, and cannot be remedied by rebooting the device: When panning the map view (no zooming that would trigger a complete re-load), map tiles that were already loaded, are cleared and reloaded. This can occur multiple times until the map view settles down. Looks pretty wild.

I just got this samsung galaxy s relay 4g. I've gone and disabled the really nasty stuff. But i'm left with one real remaining problem.
most programs that have a single icon widget, end up taking up 2 tiles vertically. some 2x1's end up taking up 2x2. Here's some examples:
The task killer icon, and juice plotter should be taking up one tile, and they're taking up two.
The battery status icon is taking up four tiles, and should only take up two.
So how do I address this?
I suppose the next question, is it sane to try to get the vanilla launcher on here? Or should I just wait for a full cyanogen release for it?
