I'm very, very new to Android and am currently trying to develop an app dealing with location. I want to start off on a map activity but after the first few times of rendering it correctly, it started giving me unrendered frangments and a rendering error. Pls Help.
Use the MapActivity provided by google in android studios.
Also make sure you have entered correct API key.
You can use this default activity on Android Studio.
Then, make sure you have an API key from google. Here's the link:
https://developers.google.com/maps/documentation/android-api/signup
After that:
Note: Always make sure that you are connected to the internet for the maps to render. Hope this helps!
I am facing a strange issue with my app - if I specify a wrong API Key, I get an authentication error as expected but when I specify the right key, I don't get any error message but just a blank screen. What is even more strange is that when I use the same Google Play Services project in a test project, the map loads and is displayed properly.
I have set the Build Target as 21 for both my app as well as the Test project. Please let me know if you might know the reason. Appreciate your help.
Check you've put the API key into the correct google_maps_api.xml. It me a couple of hours to notice there are two. One for Debug and one for Release.
Finally figured out the reason - all the processing was done on the UI thread, and my phone being slower, was dropping the UI processing. Moved most of the logic to a separate thread and the map started to get displayed.
I tried a lot of examples but still can't get it to work!
I have a grid with no maps and " couldn't get connection factory client".
I tried here and here and here and many others.
I tried to run it and on device but still the same.
Any ideas here?Any other good tutorial?
Thank you!
I see that you have tried my tutorial. The problem you describe usually happens when there is a problem with your key.
Please go over the next tutorial as well for getting your key:
Google Map API V2 Key
it this doesn't help you, try to delete the debug.keystore folder and run any android project to recreate a new key, and perform all the process of associating your key to your project using the console all over again.
And check again that you are adding all the permissions from the first tutorial in you manifest file.
this occurs when you use different key for the app in the manifest than the actual google project key. Try rechecking the key. I had the same problem, and figured it out the same way. It has nothing to deal with the code. Good Luck!
We are a team of three people working together. Right now it is hard to distribute work properly since the debug apiKey was generated on my machine. MapView stop working when running on my friends' Mac/PC. What's the best way to get around this? Should I just replace my friends' debug.keystore with mine and put the key on svn too?
Due to different debug.keystore mapview is not working...
Either create new map-apikey or create new map-api key in your Mac/PC.
I am new to Android software development and new to this site. I am hoping someone might have some experience with the problem I am having.
I've been following the Hello, MapView tutorial in order to not only learn the Android framework, but also the Google Maps library. I've tried my best to implement things exactly as the tutorial has instructed. My problem is that the application does load in my emulator (or even on my phone for that matter), but the map tiles do not load.
Searching Google I found a post by someone else on another site having the same issue, but his/her problem was that the important elements added to the AndroidManifest.xml file were not in the right order. I double-checked this in mine, but everything seems to be right.
So, I am not sure what the issue is and was hoping others have seen this before. I can provide any snippets of code, if that would help.
Thank you.
Non-loading tiles are usually the result of not having the API key set up correctly. Obtaining a Maps API key
To answer the response you left to d.: If you want to have it "just work" when you run from Eclipse you'll need to get an API key for your debug certificate. There's instructions on the same page as before. Do note that you'll have to swap back to your other key before publishing though.
I am guessing the issue is not that you have an incorrect map key, but that you do not have the proper keystore setup. The application needs to be signed by the same keystore you used to generate the map key. You've noted that you can get it to work when you sign the application yourself, but you need to setup a debug keystore in order to use the Maps API with regular Eclipse builds.
All Eclipse builds require a debug keystore; you just normally don't notice it because ADT generates one for you automatically. You should either follow the directions here and create your own debug keystore, or you should take the debug key that ADT automatically created for you (it'll show you where it created it in Windows > Preferences > Android > Build) and sign up for another Maps API key. That key will work with Eclipse.
(P.S., this does make it a hassle to compile for release, as you need to switch your key back and forth depending on the signing keystore.)
I had the issue of tiles not loading as well. As you mentioned your original post, one possibility is with the ordering of elements in the AndroidManifest.xml file. Specifically, I originally had the line:
<uses-permission android:name="android.permission.INTERNET" />
after the application element. Once I moved this line before the application element, my map tiles started loading again.
The tiles not loading is almost always a result of using an inaccurate API-key, i think. Have you checked yours?

I had the same problem... my error was in the manifest file puting INTERNET permissions inside application. After moveing it out (upside) everying was working good.
Make sure you have 3g on the top panel. If you don't then there is no internet connection. Sometimes I have to turn the emulator on and off a couple of times to get 3g to come up.
d. is probably correct. However, Internet problems will also cause similar symptoms. Be sure that your INTERNET permission is properly positioned and that there are no proxy servers/firewalls impeding access to the Internet.
Another problem could be a proxy that you are behind. The proxy slows things down a lot and it will effect your app even though the maps app and internet browser in the emulator work fine.
This is old question, but here is one more answer: if you are as hasty as me, you might accidentally copy the finger print code instead of API key from the web page :)
The Hello, MapView tutorial your were talking about is no longer valid. New V1 map applications can no longer be done.
