I have an app on the android market, which uses the mapview to display some locations. This works fine on all the devices i have tested it on. After having it on the market for a while, i see several people reporting a problem.
The mapview does not seam to display/load the tiles on the map, and only displays the gray grid. All the people reporting this, are using a HTC Desire/Desire Z/Desire HD.
I have searched for this problem, and seen many having problems with their mapview, and they often have a HTC desire, but i have not found any mention of it being caused by the Desire phone.
Does anyone have a clue to why people with Desire phones are having problems with the mapview, when it works fine for others?
I have made an update to the application, where i created a new maps api key, and it is working now.
I am not sure what caused the problem before, but i think they may have changed the type of key you have to submit for the maps key.
I have an old file where i had written a SHA1 Certificate fingerprint of the application and i am quite sure that it is the one i used to get the old maps api key. Maybe they changed something along the way, that caused it to fail on most phones?
Anyway, creating a new maps key from an MD5 Certificate fingerprint fixed it on every phone i have tested with.
