Native Map object does not work on Android

@agramonte: I was using version 8.0 when testing. If you want, I could send you the sample app that I sent to Corona support. You could then insert your google maps key instead of mine and see if that works or at least if you get the same error as I do. Let me know, and I can then send it as a private message to you here in your Corona account.

Yes please send it to me. I’ll test it out.

Ok, I’ve sent it. Thanks!

I couldn’t get your code to work but I don’t really understand it. I think you didn’t send me all of it and if this is the same thing you sent to Corona they won’t be able to help you.

local maptest = require("sampleUI.maptest") -- I am missing this file. Maptest is null.

then further down you call this:

maptest.create() -- this is null and you are calling this function from that file I don't have.

I erased everything you had except the first line and put my key in the config:

display.setStatusBar(display.HiddenStatusBar) --local maptest = require("sampleUI.maptest") local mapView = native.newMapView( display.contentCenterX, display.actualContentHeight/2, display.actualContentWidth, display.actualContentHeight ) mapView:setCenter( 37.331692, -122.030456 )

And here is the picture from my device:

The zip file submitted to support was complete. Once I added my license key, I was able to build with your mapsKey and the native.newMapView() came up and complained about an issue. I replaced the key with a key I use in a maps based app (I’m doing a Google JavaScript map in a webView because I’m overlaying weather radar on top), rebuilt and re-run your app and I got a map centered on where I live with no error.

So based on my results and Agramonte’s results, this seems to be related to your key and not native.newMapView()

@agramonte: there must be some kind of misunderstanding. The zip file I sent to Corona was exactly the same I sent to you but with my mapsKey removed. The file maptest.lue is in the folder SampleUI.  

@Rob: what was the issue that the Map view complained about? When I run it, I get no map at all. What Android version were you using? I don’t get this… 

@Rob: could you please try one more time with the zip file I sent (with my map key)? I have removed all restrictions from it in the Google dashboard, just curious if that changes anything for you.

UPDATE: I just found this in the Android logfile:

01-05 20:46:38.290 31943 31943 I chromium: [INFO:CONSOLE(50)] "Google Maps JavaScript API error: RefererNotAllowedMapError

01-05 20:46:38.290 31943 31943 I chromium: https://developers.google.com/maps/documentation/javascript/error-messages#referer-not-allowed-map-error

12-30 20:46:38.290 31943 31943 I chromium: Your site URL to be authorized: __file_url__//data/user/0/[my package name]/cache/.system/resources/corona_map_view2.html", source: https://maps.googleapis.com/maps/api/js?v=3.9&sensor=false&key=[my map key] (50)

On the credentials page of the Google Cloud Platform, you can apply restrictions. I had my restrictions set to “Android apps”, but I now understand that a Corona app is not an “Android app” in this sense since it uses a web view for displaying the map. Therefore, I must instead apply restrictions for “HTTP referrers (website)”.

Since your key worked in my app you either have no restrictions on your key, or you have entered a “HTTP referrers (website)” restriction. Can you please confirm that? If so, is the URL that you entered really " __file_url__//data/user/0/[my package name]/cache/.system/resources/corona_map_view2.html"?

It now works with your Maps API key

Rob

Ok, great, then it was the applied restrictions…

One last question: what did you enter under “HTTP referrers (website)”? Was it " __file_url__//data/user/0/[my package name]/cache/.system/resources/corona_map_view2.html" like it said in the logfile I quoted or was on some other format?

I don’t remember entering anything.

If so, your key is “unrestricted” and could potentially be used by someone else. At least according to the instructions at the google cloud platform website where the keys are handled. Since Corona apps do not have a url request per se even though the request comes from a web view, I will have to let google support help me on what url to enter “HTTP referrers (website)”.

@Rob & agramonte: thank you so much for your help, I really appreciate it!  :slight_smile:

@Rob:

Just got this from google support regarding the logfile I sent them:

The “RetiredVersion” means that the application is making a request to a version of Google Maps JavaScript API that is already retired. A way to fix this is to replace the version in the request URL. The request URL can also be found in the logs that you have sent:

https://maps.googleapis.com/maps/api/js?v=3.9&sensor=false&key=[your_map_key]

The v=3.9 is not an updated version. But, this has to be fixed by the Corona team, since they are the ones who set that up.

Another error says “SensorNotRequired”. This means that the request URL is also using a deprecated parameter which is “sensor”. This parameter is no longer working and should no longer be used. This can also be fixed only by the the Corona Team.

In other words: the request that Corona is making to Google Maps uses partly deprecated or non-supported parameters. This has got nothing to do with my error, this is the same for everyone using Corona.

Could you please forward this to your engineers?

UPDATE:

In case anyone wonders, this is the url that should be filled out with the “HTTP referrers (web sites)” choice:

__file_url__//data/user/0/[your package name]/cache/.system/resources/corona_map_view2.html

This could be a bit tricky if Corona ever decides to change the name of the html file. In that case, the request will not be valid and no map will be displayed…

I would suggest trying https://marketplace.coronalabs.com/corona-plugins/map-plugin , it’s easy to develop using Corona Simulator.

Thanks or the tip! Just curious: is the map displayed in a web view? Who is the content provider, Google, Apple or someone else?

@Divergent Monkey, I don’t believe either of those URL parameters are causing an error. I agree that they are old and not doing anything, but they shouldn’t be causing any harm either.

I’ve raised it with engineering, but I’m not sure what the priority will be on fixing it. Since we’ve gone to an open source model, we also are now using GitHub issues to track these types of bugs. Can I get you to visit:  https://github.com/coronalabs/corona/issues

And file an issue for this. Perhaps if we can’t get to it in a timely fashion, a community developer who wants to contribute to Corona can look into it.

Rob

@Rob:

True, they don’t cause any problems (confirmed by Google support) but if possible, they should be fixed just for the sake of keeping Corona up-to-date. I have creted an issue at the GitHub page. Thanks!

FYI: https://github.com/coronalabs/corona/issues/8

Did you put the string in quotes? It should be a string.

I didn’t actually test it but I traced that key all the way to the URL. This is the URL being used:

'https://maps.googleapis.com/maps/api/js?v=3.9&sensor=false&key=' + googleApiKey

Yes I put it in quotes in config.lua. Can you make the NativeDisplayObjects sample app work? Even if you have a google iap key in config.lua as well?

I looked at the source and we are certainly using “mapsKey” in config.lua in the application.license.google table.

If you’re uncomfortable sharing your api key here, you can put together a simple sample project that adds a native.newMapView() to a simple app with your build.settings and config.lua and package that up and a zip file and email it to support@coronalabs.com and we can take a look at it.
