Android Question Layout variants

[padvou]

I 've spend some time developing some app which, among others things, displays some metric charts which are in fact jpgs made especially for 1020x600@160 dpi.Device is 1024x720@160 dpi. The jpgs are 1:1 displayed on the device. I mean 1cm on the jpg is in fact 1cm when you measure it on screen.
Is there some way I can display this app correctly to another device which is [email protected]?
I would prefer to avoid re-writing stuff and having to order new jpgs to match the new device.

A workaround just for my case which worked was to change screen density in \system\build.prop
So my next question would be if some coding would accomplist this so I don't have to do it manually.
How could I execute a textreader on a file residing in \system ?

You cannot access system files on unrooted devices. I guess that your device is rooted. It is still not simple. You will need to run a shell script to do it.
Running shell commands as SuperUser

See this code: http://www.b4x.com/android/forum/threads/how-to-draw-circles-in-real-sizes-mm.19071
It allows you to get the device exact scale.

Yes target device is rooted. I 've implemented the code referenced in http://www.b4x.com/android/forum/threads/6886/#content
However since I 'm not really into linux/android shell commands, I 'd appreciate if someone assisted me with this.

I'm checking the second link out. Looks really interesting!
