How to ship an Android application with a database? Android Programming: Pushing the Limits. Developers. Android Core API - Dropbox. The Core API is based on HTTP and OAuth and provides low-level calls to access and manipulate a user's Dropbox account.
If you want to follow along, first register a new app on the App Console. You'll need the app key and secret to access the Core API. Then install the Android SDK and you'll be ready to go. Authenticating your app The Core API uses OAuth v2, but the Android SDK will take care of most of it so you don't have to start from scratch. Android SQLite database and content provider. Getting Started with Data Binding in Android. Data Binding Guide. This document explains how to use the Data Binding Library to write declarative layouts and minimize the glue code necessary to bind your application logic and layouts.
The Data Binding Library offers both flexibility and broad compatibility — it's a support library, so you can use it with all Android platform versions back to Android 2.1 (API level 7+). To use data binding, Android Plugin for Gradle 1.3.0-beta4 or higher is required. Beta release Please note that the Data Binding library is a beta release.
While Data Binding is in beta, developers should be aware of the following caveats: This is a beta release of the feature intended to generate developer feedback. Build Environment. Google. Saving Data in SQL Databases. Saving data to a database is ideal for repeating or structured data, such as contact information.
This class assumes that you are familiar with SQL databases in general and helps you get started with SQLite databases on Android. The APIs you'll need to use a database on Android are available in the android.database.sqlite package. Define a Schema and Contract One of the main principles of SQL databases is the schema: a formal declaration of how the database is organized.

You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a "sub activity" that you can reuse in different activities).
This lesson shows how to extend the Fragment class using the Support Library so your app remains compatible with devices running system versions as low as Android 1.6. Note: If you decide that the minimum API level your app requires is 11 or higher, you don't need to use the Support Library and can instead use the framework's built in Fragment class and related APIs. Just be aware that this lesson is focused on using the APIs from the Support Library, which use a specific package signature and sometimes slightly different API names than the versions included in the platform. Getting Started. Action Bar. The action bar is a window feature that identifies the user location, and provides user actions and navigation modes.

The action bar provides several key functions: Provides a dedicated space for giving your app an identity and indicating the user's location in the app. For more information about the action bar's interaction patterns and design guidelines, see the Action Bar design guide.
