***THE INSTANT New York Times, Wall Street Journal, USA Today, and IndieBound BESTSELLER*** An NPR Book of the Day Picking up where the New York Times bestselling Front Row at the Trump Show left off, this is the explosive look at the aftermath of the election—and the events that followed Donald Trump’s leaving the White House all the way to January 6—from ABC News' chief Washington correspondent. Nobody is in a better position to tell the story of the shocking final chapter of the Trump show than Jonathan Karl. As the reporter who has known Donald Trump longer than any other White House correspondent, Karl told the story of Trump’s rise in the New York Times bestseller Front Row at the Trump Show. Now he tells the story of Trump’s downfall, complete with riveting behind-the-scenes accounts of some of the darkest days in the history of the American presidency and packed with original reporting and on-the-record interviews with central figures in this drama who are telling their stories for the first time. This is a definitive account of what was really going on during the final weeks and months of the Trump presidency and what it means for the future of the Republican Party, by a reporter who was there for it all. He has been taunted, praised, and vilified by Donald Trump, and now Jonathan Karl finds himself in a singular position to deliver the truth.

Google Android dominates the mobile market, and by targeting Android, your apps can run on most of the phones and tablets in the world. This new fourth edition of the #1 book for learning Android covers all modern Android versions from Android 4.1 through Android 5.0. Freshly added material covers new Android features such as Fragments and Google Play Services. Android is a platform you can't afford not to learn, and this book gets you started. Android is a software toolkit for mobile phones and tablets, created by Google. It's inside more than a billion devices, making Android the number one platform for application developers. Your own app could be running on all those devices! Getting started developing with Android is easy. You don't even need access to an Android phone, just a computer where you can install the Android SDK and the emulator that comes with it. Within minutes, Hello, Android gets you creating your first working application: Android's version of "Hello, World." From there, you'll build up a more substantial example: an Ultimate Tic-Tac-Toe game. By gradually adding features to the game, you'll learn about many aspects of Android programming, such as creating animated user interfaces, playing music and sound effects, building location-based services (including GPS and cell-tower triangulation), and accessing web services. You'll also learn how to publish your applications to the Google Play Store. This fourth edition of the bestselling Android classic has been revised for Android 4.1-4.3 (Jelly Bean), 4.4 (KitKat), and Android 5.0 (Lollipop). Topics have been streamlined and simplified based on reader feedback, and every page and example has been reviewed and updated for compatibility with the latest versions of Android. If you'd rather be coding than reading about coding, this book is for you.
