Introducing the SD-Caching

Written by Nicolas Gramlich

Tuesday, 02 December 2008 01:41

Hello Community,

today we want to introduce you the updated Caching-feature. This updated caching-mechanism allows you to enable storing the downloaded map-tiles to the SD-card instead of to the internal-ROM.

Pros:

No Internal ROM is used (you can habe more applications installed!)
You can store many more(!) - tons of maptiles, just as big as your SD-Card is!
You can preload much more images, so you can have detailed maps even without coverage!
Internal-ROM is used as a fallback, if no SD-Card is inserted.

Cons:

Its a little bit slower than storing to the internal ROM (at least with my SD-Card)

This is how it looks like:

If I find no bugs, I'll send out a version to all covered+registered users, tonight.

_{Note: You currently can set sizes, bigger than the actual free space on the SD-Card is. AndNav will probably crash then}

Best Regards,
Nicolas

Leave me a not with your mail and I'll send it to you.

Thanks! I've sent a message to plusminus on the forums. I'm not sure how useful I'd be as I'm in the U.S., though. Quote

Ah, I was wondering where I could get a copy. No worries! I'll just check out the next version when it's ready ^^

usually you receive the

Quoting worry:

Thanks, Nikolas.
I've registered and put myself on the map, but still does not understand how to get a copy of andnav2 to test (no email).

Is there any chance you (or somebody) can send me a copy on email?

yes its working already.
The photos from the previous link are live ones from my G1.

Currently you can only preload the tiles along a route. I'll add a feature that you can preload complete rectangle-areas, like "I want the complete maps of D.C. preloaded"

Best Regards,
Nicolas

Quoting Tim Fedders:

Nicolas,

Yes I was thinking of "Preloading". Do you have that working yet on AndNav2?

Caching is transparent to the user. You only can set the max-sizes.

What you maybe were thinking of is what I'm calling 'Preloading'. See:

Quoting Tim Fedders:

Nicolas,

Can you make a video of how you do the caching. I would like to see how you let AndNav2 know what to cache.

Thanks,
Tim
