Android 2.1 is a minor platform release deployable to Android-powered handsets starting in January 2010. This release includes new API changes and bug fixes.
The sections below provide information about changes made to the application framework API provided by the Android 2.1 platform.
The Android 2.1 platform delivers an updated version of the framework API. The Android 2.1 API is assigned an integer identifier — 7 — that is stored in the system itself. This identifier, called the “API Level”, allows the system to correctly determine whether an application is compatible with the system, prior to installing the application.
To use APIs introduced in Android 2.1 in your application, you need to set the proper value, “7″, in the attributes of the <uses-sdk> element in your application’s manifest.
For more information about how to use API Level, see the API Levels document.
The following is a summary of some notable changes to the framework APIs.
The following additions provide APIs for you to develop animated wallpapers:
android.service.wallpaper package.WallpaperInfo class.WallpaperManager.SignalStrength class provides information about the device’s current network signal. This can be acquired from the new onSignalStrengthsChanged(SignalStrength) callback.onDataConnectionStateChanged(int, int) callback.View methods isOpaque() and onDrawScrollBars(Canvas).RemoteViews methods addView(int, RemoteViews) and removeAllViews(int).ViewGroup methods isChildrenDrawingOrderEnabled() and setChildrenDrawingOrderEnabled(boolean).WebStorage methods to manipulate web storage databases.GeolocationPermissions methods to get Geolocation permissions from, and set them on the WebView.WebSettings methods to manage settings for app cache, web storage, and zooming based on screen density.WebChromeClient methods for handling video, browsing history, custom Views, app cache limits, and more.
I Wish you Merry Christmas and Happy 2010!
