Memory/Cache configuration

Some phones, especially with limited memory (e.g. Nokia S40) may require tuning of network cache, as default cache parameters could cause OutOfMemory exceptions.

Default network cache configuration for MapComponent and MapItem is set with following commands:

final MemoryCache memoryCache = new MemoryCache(128 * 1024);
final RmsCache rmsCache = new RmsCache("ML_NETWORK_CACHE", 64 * 1024, 5);
setNetworkCache(new CachingChain(new com.nutiteq.cache.Cache[] { memoryCache, rmsCache }));


You can override these settings if you call same commands with different parameters after creation of MapItem or MapComponent, and before call of StartMapping().

One strategy for troubleshooting of OutOfMemory you could remove rmsCache, memoryCache or both from the CachingChain, then no caching is used. If this helps, then optimal values for the cache should be found for the device and specifically for your application.

Take also look to Javadoc comments, especially http://www.nutiteq.com/javadoc/com/nutiteq/cache/RmsCache.html which has some hints how to estimate good cache size.
