[Simond]

The Android 1.5 platform will include many improvements and new features for users and developers. Additionally, the SDK itself introduces several new capabilities that enable you to develop applications more efficiently for multiple platform versions and locales.Android SDK 1.5. this is just a early look at SDK where is final release of Android SDK 1.5 will be at the end of this month.

The new SDK has a different component structure than earlier SDK releases. This means:

• The new SDK does not work with older Eclipse plugins (ADT 0.8)
• The old SDKs (1.1 and earlier) do NOT work with this new Eclipse plugin (ADT 0.9)

There's no word on exactly how 1.5 will come to existing Android handsets in the field, but as far as we can tell, there's nothing listed in the changelog that would prevent current hardware from taking full advantage -- and the OHA is going to be releasing a series of articles about new-to-1.5 features in the coming weeks to help devs "prepare your applications for the release of Android 1.5 on phones."

Because the 0.9 ADT is not compatible with older SDKs, you cannot build against your existing 1.1 (or earlier) SDK while using the 0.9 ADT. If you already have a pre-0.9 ADT plugin installed and would like to continue developing for 1.0 and 1.1 devices, you should install a new copy of Eclipse to run the 0.9 ADT (and the new SDK). Otherwise, if you're ready to upgrade your Eclipse IDE to develop for Android 1.5, you can continue by uninstalling the old ADT and installing the new one.

The "New Android Project" wizard has been expanded to use the multi-platform capabilities of the new SDK.There is now a "New XML File" wizard that lets you create skeleton XML resource files for your Android projects. This makes it easier to create a new layout, a new menu, a new strings file, etc.Both wizards are available via File > New and new icons in the main Eclipse toolbar (located to the left of the Debug and Run icons). If you do not see the new icons, you may need to select Window > Reset Perspective from the Java perspective.

Installation Steps

First, download one of the SDK packages
Unzip the SDK. A new SDK directory is created that contains the uncompressed SDK contents.
If you use Eclipse, download the new ADT Eclipse plugin (0.9) zip file from the table at the top of this page. Do not unzip it.

Note that the command-line samples that follow assume that you're working from your SDK package's tools/ directory.

APIs provided in this SDK are subject to change until the final Android 1.5 SDK is released. You should not compile any applications for distribution using this version of the SDK. If you do so, your applications may not function properly when deployed to Android-powered devices running the final Android 1.5 platform. Please wait for the final Android 1.5 SDK before distributing applications built on the Android 1.5 system image.
