MapTileFileArchiveProvider eats lot of memory #337

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Copy few offline map zipped files to osmdroid folder 
2. Run mapviewer

When i used osmdroid-android in my project with offline maps, 
MapTileFileArchiveProvider eats a lot of memory for each zip archive, sometimes 
0,5 MB of memory for each zip file. When i cross 6MB of memory, application 
begin throwing a lot out of memory exceptions.

The main memory eater is at
org.osmdroid.tileprovider.modules.getZipFileArchive line 26;
return new ZipFileArchive(new ZipFile(pFile));
