I am new to Android development and am currently creating a Space Invaders game to help me familiarise myself with surfaceview's, bitmaps, canvases, threads etc etc.
So far so good. What I currently have runs in a real tablet quite nicely.
However, on an emulator for a low dpi resolution it looks awful.
I realise that Android screens come in many different resolutions and I might need to scale my sprites down if the resolution is lower than I expect.
I just can't quite get to grips with the best way to ensure everything "fits": that is to say all sprites are on screen, in proportion, and when they move, they move proportionally. On a PC I'd use a back-buffer of a fixed size that never grows or shrinks, blit to that, then scale the back buffer up/down to the extents required, but on Android??
I know somewhat about screen densities and have created mdpi and hdpi sprites (48 x 24 and 48 x 32 pixels width and height respectively) and I'm wondering if these sprites are in proportion for the dpi settings?
Any help is appreciated.
Do you also have created ldpi sprites?
