Osmdroid maps not loading on my device
I have an Alcatel One Touch 7040, when i test my sample of osmdroid on it, the maps don't render. I have tested on other devices, the maps are rendering in them properly, only on this device they are not. I thought my device memory was low so I deleted some apps from my device, still nothing improved, can someone please tell me what could be the reason?
Following is my logcat(some parts of it has been removed because word limit exceeded) :

Answer
What API level is the device? It could be a permissions issues. Sometimes android also mounts Environment.getExternalStorageDir() as read only, which is wrong. One of these days I'm going to fix this with a work around.
Does the example application provided by osmdroid work? Not only do you have to start it, you have to zoom in a bit. The sample app comes with a few cached tiles.
Looking at the stack trace, Environment.getExternalStorageDir() is returning a read only mount point. So the only reasonable solution would be to tell osmdroid to use a different location for the cache on that type of device. It can be done easily but it must be BEFORE the mapview is created. This link has the API calls to make with osmdroid
Using osmdroid without getting access to external storage
This answer https://stackoverflow.com/a/15612964/1203182 has some great code to return a list of mount points/paths that are writable. It might be a good idea to prompt the user to ask where to store the cache
Edit: Added in osmdroid 5.6, the workaround i discussed was added, along with a samples in the samples app "Open Map" that shows you how to use it. Default cache location with osmdroid 5.6 and up is the largest writable storage partition. This will then be saved as a preference (again see the sample app)
