I encountered a bug in Android version on Motorola Defy (2.2.2). In this device there are 3 modes of work based on docking station existence: standalone, car and multimedia (just 'on desk' mode in dock). In versions up to 1.0.18 (included), TB just shuts down itself during mode changes (puting or removing Defy from docking station). It was little annoyed (especialy in car, with track logging enabled). But from 1.0.19 it simply hangs in such situation with black screen. I must kill TB to run it again and it's really painful to do during car driving.
Of course another bug (java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 2) also occurs, but only after screen unlock, and I think that it's not so critical as above.

Regards
Marek

[quote="guest"]As a result TrekBuddy always starts without a map selected, in the configuration menu the default map string is empty. The other configuration settings however are saved correctly so it seems.

Confirmed on both SE C702 and N C05. Very anoying. Also, after upgrade from previous version scrolling got noticeably slower on C702. I use somewhat bigger 512x512 tiles to get better compression, and now its about .5s, previously it was .1-.2s (On C05 its >10s, probably due to broken Java, still have to try with older TB versions to confirm this).

PostPosted: Sun Jan 29, 2012 7:45 pm    Post subject: too fine screen resolution Reply with quote

Hi!

I`ve been using TrekBuddy for a while. Now moved to a new Android pone with screen resolution of 854x480 on a 3.7" screen. TB runs like a charm, but the pixels of my good old maps are too small on it to see without a magnigier glass. Well, I would like to beg for an option to use the same maps in a - say - four times bigger mode.

Or is there any way to obtain such an effect? Includimg any trick during map creation...

Marcus, I have a Defy too. You can see the little map details? Are`nt they too small for you?
On my old Nokia E52 the pixels were about four times bigger, that was perfect to see.

And I have to say, my Defy handles default atlas settings with no errors (2.3.5)

Defy's screen ppi is near 250, so it means E52 should have ppi near 60 ? Wink
Not true Smile
There is not good way to have map adapted for too different density screens.
Map zooming can eat battery faster (transformations), having natural scale of map may be not possible (for simple transformations), etc.
We have info about screen resolution in wiki's devices section, but ppi not.
The best way is to have map prepared for screen density of used device. Not easy game.

I plan to (try to) implement simple "magnifier", I know it is not easy to read maps on high ppi screens.

In all raster apps map is shown in natural scale first, and next "magnified".
If map have different ppi in production, 100% scale means what on such screen ?
Map can be still unreadable on high ppi screen if is rasterized in much lower ppi.
And probably will never be in natural scale for simple magnification factors like x2, etc (if map & screen ppi are different).

Ranger: well, I've made the actual calculation: the E52 has a 2,4" scrren of 320x240 pixel, versus the Defy, having a 3,7" screen of 854x480.

This means, the E52 displays 166PPI and the Defy shows 264PPI

The rate of the two PPI-s is around 1.5, which means that the AREA of a pixel on the E52 in 2.5 times bigger than on the Defy. That makes a difference.

Even though, maybe we are on the wrong way requesting zoom option in TrekBuddy, maybe it would be better to ask for a new feature in MobAC, to generate the magnified maps with any convenient magnifying factor.

Right. As I wrote game is not easy Wink
Rescaling maps on PC is possible, but files are more heavy Sad
Second way is to choose next phone with similar ppi (or smaller), when changing device. It works Smile

Well, I do not plan to change device for a while. The main purpose of my Defy would be the potential of remote server maintenance over SSH, and for that, the big screen resolution is a bliss.

Yep. There are many reasons to choose device. And ... suitable maps.
