When I draw a arrow on the Demo app, the arrows is too small.
How can make arrows to a bigger one ?
It looks like the dpi resolution is incorrect.
Can you tell me which resolution you send to the renderer ?
I got the device dpi by "displayMetrics = context.getResources().getDisplayMetrics();" as follows
I don't know why the devices dpi is so small.
However, can I improve it with a bigger arrows? Or does have any way to get a bigger arrows?
It looks like advertised dpi does not match actual dpi on your device.
What is your device ? Which version of Android do you use ?
A bad dpi will lead to bad recognition results, so you should set the correct dpi.
To find out the actual dpi of a screen you must measure the screen size :
xdpi = 25.4 * (screen width in pixels) / (screen width in mm) ydpi = 25.4 * (screen height in pixels) / (screen height in mm)
Dear Maël ,
Thanks for your quickly replay.
I just set dpi an fixed value 160 with screen resolution in 1920 x 1080 pixels.
It's look like bigger.
int _fixedDPI = 160; engine.createRenderer(_fixedDPI, _fixedDPI, this);
