Kotlin for Android App Development will help you rapidly understand Kotlins principles and techniques, apply Kotlin in production app development, integrate Kotlin with existing Java code, and plan a migration to Kotlin, if you choose.If you have at least basic programming experience (with any language), Peter Sommerhoffs well-crafted overview and examples will help you get quickly up-to-speed with the Kotlin language, its constructs, and its advanced functional and object-oriented capabilities.Once youve mastered these foundations, Sommerhoff walks you through two complete app development projects, introducing best practices and emerging patterns for writing code thats robust, concise, readable, and highly performant. Understand Kotlins goals, principles, advantages, design, and constructs Take full advantage of functional programming in the Kotlin environment Write more concise and reusable code using Kotlins object-oriented features Interoperate with existing Java code, and plan a migration to Kotlin Use coroutines to efficiently handle concurrency Capture data via third-party APIs, map it to internal data representations, and present it to users Master best practices for architecting Kotlin Android apps Improve productivity and readability creating simple domain-specific languages in Kotlin Register your book for convenient access to downloads, updates, and/or corrections as they become available.

Excellent can opener.
Color: Red/Battery
Love it! Works like a charm. I have arthritis which made opening cans with the type I’d used for years very hard. I didn’t want one on the counter, this fits perfectly in a drawer. I know a couple our friends have ordered one.

Worth the Money
Color: Red/Battery
I bought this thinking, "Will it really work the way it shows?". The answer is yes. Put it on the can, press the button, and then it does its thing hands off. It does leave a smooth edge too. Not too speedy, but better than having to fight with your manual to get it to catch the edge.

Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.

Three froth/blend options, rechargeable, comes with container
Color: Rechargeable with Storage Box - Silver, Color: Rechargeable with Storage Box - Silver
I watch a gentleman online who always talks about how in his 40 years he didn’t know x, y, z, and ends with “ain’t no way.” He made this 3-ingredient — 4 with ice— iced coffee, and used a handheld frother, so after shopping for ingredients, I went in search of a frother. What I liked about this one is that it’s not battery operated, but instead is rechargeable. It comes with three attachment, one of which I can use for cake batter, whipping up eggs, making homemade whipped cream, and also sauces and gravy. It also has a case so I am storing it with my coffee paraphernalia. It has three settings and I used the high setting. As you can see it really froths up the ingredients. I’m very pleased with my purchase and thought about all the times I need a slurry of water and cornstarch to thicken soups and stews. I don’t know the charge life yet, but so far, so good. What you see in the cup is 2 tablespoons of sweetened condensed milk, 3 teaspoons of instant espresso, and 2 ounces of water. Then you add the ice and your creamer, half-and-half, or barista lover’s oat milk, and you’re done. Not too bad, as my grandpa used to say.
