i have made an android application and in it , there is one scenario when the user clicks on an address and that address shows up on google maps.
Now when i tested the application on the emulator, the google maps did load properly, but now that i am trying the same on my htc desire z, the maps is not loading.
Although the maps application which came built-in in my phone is loading google maps correctly.
what could be the problem? why is my application not able to load the map view?
thank you in advance.
EDIT: i have obtained a google map api key and have included it in the mapview that i am using.i have added overlays and etc. It is all showing fine on the emulator , but on my device it is not showing any maps. The overlays are visible.
There is a difference between a debug maps API key and a release maps API key. With the first it will only run on the emulator.
Unless you have visited the Google site twice (once to get a key which matches the debug keystore and once to get a key which matches your release keystore) then you haven't got a release key and your app won't run on real device.
Our Android developers were also facing this problem. We solved the problem like this:
We generated API keys from each machine and added the Key to their respective main.xml file. So each developer had a separate api key.
We started the emulator from the command line using the android "emulator" command which is located in the tools directory and started with the proxy option instead of starting it from eclipse, eg :
E:>emulator -avd New_Device -http-proxy http://202.0.0.203:808
Most probably, you didn't register your application into the system. This is the link.

If this is not the case, please provide the error details from Logcat.
You need to get an API key from Google.
Here is a good article that explain how to obtain API key.

I have done an application for android , and I used Android Studio , in this app I need to use Google maps, so while I was working i did all that stuff about the API key to use google maps, i was proving my app on my own movile, and there everything works fine, even googlemaps, but when I put my app on the store, i downloaded it from another device, and there google maps does not work. =(
Do you have any idea why does this happen ?
There might be an issue with your API key for map. (ie. Either there is issue in defining package name or SHA key)
Try to re-generate API key with all proper info. and re-build your project.
Need help , tired of following the tutorials but still no results. I am using android studio and trying to make map app. Tried using the map template in studio as it is just by entering my key bt no matter what i do , i get the same results, blank screen with google log. Google maps console shows zero request from my key to accces maps.
you must add api key, for this need register your application in the Google Developers Console
https://developers.google.com/maps/documentation/android/start
For starters, you need to create a project on Google Devlopers Console.
See this tutorial.
Thank you devs for support but I solved my problem myself by digging whole day , after implementing maps layout activity and manifest and other required files , the app should be build with the keystore provided in android sdk itself instead of our own keystore. keystore path - C/user/{username}/.android/debug.keystore with alias as "androiddebugkey" and password as "android".
I need to update an Android app that was developed by someone else. Update by itself is simple, it's simple changes to XML layouts.
So I have a following plan:
update an app (done)
test it on emulator (- maps don't work) stuck here!
test it on devices
release updated version to the store.
Unfortunately I am having mulitple problems with the app.
At first, it doesn't compile because the Project Build Target API was set to Android 2.3.3.
Is there any reason why it wasn't set to Google APIs 2.3.3 ?
When I change it to Google APIs it compiles and runs but I my maps don't display correctly.
All I can see is gray rectangle and annotations on top of it. I am getting following error message associated with it.
05-11 20:45:42.554: W/System.err(598): java.io.IOException: Server returned: 3

As far as I understood from searching with Google and Stack Overflow that might be related to signing up the application. Currently app is using v1 of Google Maps.
Deleting debug.keystore and key set doesn't help.
I am not sure how to proceed with it. Any help will be appreciated.
In order to make maps display you need a signing key that is associated with the API key application was using. Android API v1 is now deprecated, so your options are limited:
contact previous developer and ask them for debug.keystore, which is stored in ~/.android/ or C:/Users/user.name/.android/ directory or
use release signing key for testing (this might be cumbersome)
Depending on what application is that it might also be a good or bad idea to switch to API v2. New API still has some ugly impl bugs, but you won't notice them if maps usage is simple. The API or v2 is pretty good.
I try with google maps application in developer site.
Generate api key and runs it in emulator smooth.
The problem is when I deploy it in real device it shows only grid checks.
I also generate release key and pasted the key in layout mapview.
Whats wrong with that.
Kindly help me with brief explanation.
The only thing I can think of is the data connection. Has the phone got a good reception? Does the Google Maps app work on the phone?
I am able to see Map in emulator but once I load app on device map does not show up.
Emulator have target as google api 1.6 and device have android 1.6 loaded.
Is this diffrence causing issue?
please help and thanks in advance.
Are you just seeing gray tiles? In that case it's almost definitely the API key that's wrong. The Emulator uses the debug keystore, with androiddebugkey, so you should create an API key for that. Remember to change it when you publish the app to the market =)
Obtaining an API Key
While the problem is most likely the one that Mr. Hedlund suggested...if the built-in Google Maps application also does not work, it is likely to be a problem accessing the Google Maps tile server from the emulator over the Internet. You would need to discuss this with your IT department.
sorry i know its a dead topic but just wanted to add my experience with this;
u need the maps api key to be based off of the current keystore you are using
i had exported my project using a new keystore but a maps key generated from my old keystore. once i used the new keystore to generate a new maps key everything worked
I had the same problem with gray tiles, even though I had created/verified the API key, and had previously had the map working for some time. Turns out at some point, I edited the manifest file and moved the permissions lines. They apparently need to go BEFORE the application element. Thanks to Alan LaMielle (link) for that solution!
