Who This Book Is For

If you are a C# developer who wants to develop Android apps and enhance your existing skill set, then this book is ideal for you. Good working knowledge of C#, .NET, and object-oriented software development is assumed.

What You Will Learn

• Build a multi-view, orientation-aware Android application with navigation
• Lay out content using the LinearLayout, RelativeLayout, and TableLayout layout managers
• Use a ListView (AdapterView) and Adapter to build a view that is populated from server data
• Consume REST web service to perform GET, UPDATE, DELETE operation
• Use Android SQLite for data persistence and caching
• Capture the current location of a device, determine the street address, and integrate with the map app
• Test, debug, and deploy an Android app

In Detail

Technology trends come and go, but few have generated the excitement, momentum, or long-term impact that mobile computing has. Mobile computing impacts people's lives at work and at home on a daily basis. Many companies and individual developers are looking to become a part of the movement but are unsure how to best utilize their existing skills and assets. The Xamarin suite of products provides new opportunities to those who already have a significant investment in C# development skills and .NET code bases, and would like to enter into this new, exciting world.

This example-oriented guide provides a practical approach to quickly learn the fundamentals of Android app development using C# and Xamarin.Android. It will lead you through building an Android app step-by-step with steadily increasing complexity.

Beginning with an overview of the Android and Xamarin platforms to provide you with a solid understanding of the underlying platform, we gradually walk through building and testing a Points of Interest Android app using C# and the Xamarin.Android product. You will learn to create ListView and add detail view to your Android application. You will handle application behaviors on orientation changes, before learning the different techniques to manage resources and layouts to support multiple screen sizes. You will then access a SQLite database in a cross-platform way and add location features to your application. Finally, you will add camera integration to your application and deploy your app to the various Android app stores.

Style and approach

An example-oriented, comprehensive guide to gain an understanding of both the Android and Xamarin platforms.

詳細內容

科技趨勢來來去去，但很少有像移動計算這樣引起興奮、動力和長期影響的。移動計算每天都在工作和家庭中影響著人們的生活。許多公司和個人開發人員希望成為這一浪潮的一部分，但不確定如何最好地利用他們現有的技能和資產。Xamarin 套件為那些已經在 C# 開發技能和 .NET 代碼庫上投入了大量資源的人提供了新的機會，並希望進入這個新的、令人興奮的世界。

這本以實例為導向的指南以 C# 和 Xamarin.Android 為基礎，提供了一種快速學習 Android 應用程式開發基礎的實用方法。我們將逐步引導您透過使用 C# 和 Xamarin.Android 產品進行建立和測試興趣點 Android 應用程式的過程，並逐漸增加其複雜性。

從 Android 和 Xamarin 平台的概述開始，以便讓您對底層平台有扎實的理解，我們逐步介紹使用 C# 和 Xamarin.Android 產品建立和測試興趣點 Android 應用程式的過程。您將學習創建 ListView 並將詳細視圖添加到 Android 應用程式中。在學習支援多個屏幕尺寸的資源和佈局技術之前，您將處理應用程式在方向變化時的行為。然後，您將以跨平台方式訪問 SQLite 數據庫並為應用程式添加位置功能。最後，您將為應用程式添加相機整合並將其部署到各種 Android 應用程式商店。
