Change in MapComponent?

[kevin....@gmail.com]

I have been using a MapComponent with the GoogleMapsProvider as the source of the map data.  This has been working well for my needs.  The last build I did, I find that the map never draws on my phone.  My location pins show up as expected, and they move across the screen as I'm driving around, but no map!

It works fine in the simulator (although I wish the coordinates didn't change so fast there: I get nullpointerexceptions because the map moves faster than the interface can draw it), but it hasn't worked on the phone (android 2.3.5; I will check a 4.X device later).

Anyone know if there has been a very recent change to the MapComponent that would cause this behavior?

Thanks.

[Steve Hannah]

Can you estimate some bounds on when the change would have occurred?

Sorry, I can't really be precise, but the new build I did yesterday (2/27/14) showed the problem behavior, and a prior build that showed the map correctly was probably at least 2 months ago.

Can you post a stack trace for the null pointers?

To be clear, the null pointer exceptions only happen in the simulator, and like I said, I think it's only because the simulated position updates happen too fast for the simulator to draw them quickly enough.  The simulator has me flying over Manhattan at about 200 mph, I would guess.  If that's what you want to see, I can supply it.

It might be helpful.  Especially since, at this point, that sounds like all we have to go on.

That's a strange place to get a null pointer.  It looks like it failed to create the buffer mutable image.  But it seems like this should never happen.  Are there any other warnings or errors leading up to this?

Ran it one more time and here's what I got.  After I get this error, the display no longer updates, but the location listener continues to spit out the coordinates.

I don't know.  Maybe Shai or Chen have some ideas.  If you can provide some errors from the android log it might shed some light.

Okay, I just updated my CodenameOne libraries, and everything is different now.  Different from the standpoint that I now no longer get a map in the simulator.  The location listener is working correctly, I get all of the POI's that I'm expecting, I just don't get a map!  And the simulator no longer throws NullPointerExceptions.  I'm sure things are working much better now that I've got current libraries, but I can't explain why I'm not seeing a map.  When I look at the map in the debugger, I see 9 tiles loaded, so I know (I think) that I'm getting map data, it just isn't being displayed.

If you don't use google provider does that work?
Its possible you ran out of quota to the map API.

[kevin....@gmail.com]

It does!  I see the OpenSteetMap map just fine.  Off to the GoogleApps dashboard!

[kevin....@gmail.com]

Okay, checked my Google APIs and the following are turned on: Geocoding, Google Maps Android, Google Maps Geolocation, and Google Places.  I get responses from the Google places API with no problems, and I haven't any quota problems at all.

Still stuck...

Turn on "static maps" on the Google console.

Thanks Chen, that fixed it.  However, I'm not sure I understand why.  I had never turned on that API previously, and it has always just worked...

Thanks again.

Google has the habit of changing stuff all the time without proper QA e.g. see our recent App Engine issue.

I can confirm these same null pointers, I just spent a month trying to fix it, only happens on bb/android for me. Im about to update the libraries so I hope its gone :D

Make sure you are not violating the EDT, I am guessing you are changing the text of the TextArea not from the EDT thread
