Hi

I am not new to the forum, but until now I did not have account.

Some time ago, i developed following program on C:
https://github.com/nmmmnu/Mandelbrot

and week ago I port it in Java for Android here:
https://github.com/nmmmnu/MandelDroid
so I can play with touch controls and export coordinates for the C version.

you can download directly from Google Play:
https://play.google.com/store/apps/details?id=nu.nmmm.android.mandeldroid

Any suggestions and criticism will be welcome!

Nice app! Darkbeam, the menu appears if you tap the back button.

@DarkBeam - if there is no hardware menu button, menu is "linked" to back button, but you need version 1.1

I did not know double click must zoom - will do it next release.
Is there any other "standard" things people expects?

Fast - I am using "normal" double and simulating complex with them:

https://github.com/nmmmnu/MandelDroid/blob/master/src/nu/nmmm/android/mandelbrot/FractalCalculatorMandelbrot.java#L68
Code:
double zx2 = zx * zx;
double zy2 = zy * zy;

if (zx2 + zy2 > ESCAPE2)
return i;

zy = 2 * zx * zy + y;
zx = zx2 - zy2 + x;

this does not allow me to do anything else than cube, but works quite fast... (x = real, y = imaginary)

I also did not used abs(), because in my C experience, it works slower than simple if's.
>>> correction - seems I lied about abs()

share currently is not implemented, but probanly in the future - depends how difficult it is to be implemented.

about sd card - i tried to do it as easy as possible, i probably need to change it to dedicated directory, because if I use pictures, it will get mixed with camera shots / uploads.

Fast and simple, nice. But the zooming makes the fractal  move too much, I think.
