Some notes specific to android, since you're on a tablet. USUALLY, your menu will auto-select the most obvious tool for whatever you're doing. But be careful, if you have a tool manually selected (especially the pickaxe!), it may take that action instead, and the pickaxe will un-till tilled soil and destroy planted seeds or plants.
You can plant seeds by hoeing on any of the light brown dirt after you clear weeds and rocks and fallen branches off it. Select the seed packet and click on the hoed spots to plant, and select the watering can then tap the spot to water it. You will need to water every day.
Walk to any farm exit to leave to another map. You can tap to auto-walk to a location, but I did notice that on the android version, some exits are stubborn or can even be covered by the menu if on the right side of the screen.
Your tools should be on the left, per below, as are your other backpack slots. They will end up numerous enough to run off the bottom of the screen, but you should be able to touch and scroll up/down on them. ON the right, the exclamation point box are your current quests (you have a couple right from the start) and the three lines below that is your menu, which includes a bigger inventory screen for your backpack plus any items you're wearing, maps, crafting (you start with a couple of recipes, including chests for storage), friendship data with villagers once you figure out how to leave the farm, collections (anything you caught, shipped, letters you received...) and other such data.
In the first bit, you'll run out of energy fast. Once it warns you that you're getting exhausted, stop chopping things or breaking rocks and be *really* careful how much forage you pick up (go too long and you will SLOOOOOW down, and walking slooooow is really annoying), but you can use the scythe to cut weeds, and you can go to town, shop or talk to folks. In the first couple of days I'd advise doing your shopping by buying salads at the saloon, not seeds; food restores your energy and salads are the most efficient for their cost at this early stage (Later, there will be LOTS of better food options).
So not necessary for me. Though they could most likely be useful for someone who's not played any farming game before.
