Happens here too.

• press play with no cells selected
• touch and hold on screen while snackbar is showing to make FAB disappear
• release touch once snackbar has disappeared

FAB will appear in the raised position as if snackbar still on screen

once cells can be selected by swiping. Start button should move off screen while finger is being swiped so that grid is not obscured, then move back on screen when finger is raised

consider different approach than new AsyncTasks looping

Extra space is left at the right and bottom where there is some room, but not enough for a cell

FAB hides while cells are being drawn and reappears when finger lifted.
This works for longer touches, but a quick tap causes FAB to hide and another tap is needed to redisplay

Currently grid expands beyond screen limits. Cells at screen edge are half visible, others are off screen

after a while of play, rotating device or reopening game after doing other things may show full live grid.
This is an animated vector drawable issue. may be fixed by setting cells drawable with just plain vectordrawable initially rather than the animated version, then just use animated during gameplay

Rules need to be broken down and more engaging/visual.
Initial card screen could be shorter with the option to either see the rules, or just play.
Playing transitions straight to the game grid.
option to see rules brings up full screen viewpager breaking rules out into separate pages with diagrams.
style viewpager similar to Google Docs or Twitter, bold background colour which transitions as page changes.

Intro screen to include feature image (matching playstore) and App Logo in large toolbar.
When transitioning to game, Toolbar should collapse up with image fading into solid toolbar.

May require change in structure to use fragments and single Activity so there is only one Toolbar

When blank grid first appears use icon to hint at the user drawing cells

use Thread for game loop
put this in model, and remove async task loop from Presenter

when all cells on screen are permanently alive or where there is a constant loop of the same living/dying cells; do something

Shared element transition should use cardview and FloatingActionButton as two separate shared elements, but will only work with one at a time. Has slight illusion of both as CardView in intro activity contains fab, but won't work if FAB is moved out of cardview.

If app is exited during game screen and Activity is destroyed by system, app will crash upon resume.
This error can be forced by enabling 'Don't keep activities' in developer options

Currently 'touch app' icon will fade in and out on first entering the game screen to encourage users to draw cells. users don't always realise they can swipe the screen to draw multiple cells and will instead only use finger taps. Make icon move across screen at same time as fading in/out to encourage swiping

Start button should turn into a reset button once game started, then change back to start button once reset has been pressed.

currently initial grid state is set by tapping one cell at a time, should be able to select multiple by swiping finger

For people who don't read the instructions click ok to go to game then hit play

turn play/reset button into a Floating Action Button at bottom right

What do?
Rotating during a game resets the grid.
Grid size adapts to fit screen so landscape and portrait have different column and row count.
Possibilities:

• No rotation at all.
• rotation allowed, but disabled during a running game
• try to use same grid (probably messy)

• open app
• hit FAB to go to game
• change phone orientation
• press back button while phone is in changed orientation

Likely to do with timing of Async Task.
Reset button kills all cells, but Async Task already running, subsequently returns output causing live cells.

See this StackOverflow answer

stop async loop when activity is left

currently you can choose your living cells, but once one has been selected it can't be deselected

delay in shared element transition.
Can grid setup be done after transition? Or moved off main thread?
