Android SDK versione 17: nuovo aggiornamento

Sicuramente questa notizia farà molto piacere a tutti i modder e i developer poiché l’Android SDK è stato aggiornato alla versione 17.

La versione 17 porta moltissime novità tra cui l’aggiunta del supporto nativo dell’emulatore sui sistemi x86. Da prove effettuate l’Android SDK versione 17 è molto più stabile ed è stato introdotto anche il supporto multitouch.

Sicuramente vi consiglio di provare questa nuovissima versione dell’Android SDK. Fateci sapere cosa ne pensate…

Ecco il changelog ufficiale:

ADT 17.0.0

General improvements:

• New build features
• Added feature to automatically setup JAR dependencies. Any .jar files in the /libs folder are added to the build configuration (similar to how the Ant build system works). Also, .jar files needed by library projects are also automatically added to projects that depend on those library projects.
• Added a feature that allows you to run some code only in debug mode. Builds now generate a class called BuildConfig containing a DEBUGconstant that is automatically set according to your build type. You can check the (BuildConfig.DEBUG) constant in your code to run debug-only functions.
• Added support for custom views with custom attributes in libraries. Layouts using custom attributes must use the namespace URIhttps://schemas.android.com/apk/res-auto instead of the URI that includes the app package name. This URI is replaced with the app specific one at build time.
• Improved Lint features. See the SDK Tools r17 release notes.
• Improved the Lint user interface
• Added Run Lint toolbar action with a dropdown menu for selecting specific (or all) projects, clearing results and other actions.
• Updated the results window to be organized as a tree rather than a flat list. Each issue type has a single top level item, which makes it easier to quickly scan through the reported issues and narrow down to the issues you are most interested in.
• Added many new toolbar actions to the results window, including expand/collapse, ignore in file, ignore in project, ignore everywhere, show options, and configure columns.
• Added new column options for the Lint Warnings tab, such as category, priority, project, file and line. The column selection (as well as the column sizes) are persisted. You can also click on columns to sort by those values.
• Added Enable All and Disable All buttons to the Lint Options dialog, and a search filter textbox to filter by issue id, summary and severity.
• Added Quick Outline for XML editors (Ctrl-O, Command-O). This feature shows the structure of the current file including icons and ids, lets you filter and quickly jump to specific ids.
• Updated the resource chooser to shows the resolved value for resources. For example, when selecting @string/hello the chooser displays a resolved value such as “Hello World”). The resource chooser also now allows you to edit the chosen value directly.
• Updated Layout Editor so that it does not assign default ids to layouts, includes and merge tags. This behavior tended to pollute the namespace with a lot of unused resources since layouts are not usually manipulated via code, or referenced from XML. (The RelativeLayout editor automatically assigns ids to views without ids when pointing to them.)
• Added ability to export screenshots from the Layout Editor

Bug fixes:

• Fixed problem using Layout Editor with SlidingDrawer
  which could not be dragged into the layout on some platforms.
• Fixed preview rendering for SlidingDrawer and TabHost. (Issue 23022).
• Fixed issues that could prevent layout rendering due to unresolvable resources. (Issue 21046, Issue 21051)
• Fixed a bug in resource chooser which made some types of framework resources impossible to select. (Issue 20589)
• Fixed a bug in the formatter where a certain whitespace pattern could result in a non-space character getting deleted. (Issue 23940)
• Fixed a locale bug affecting Turkish locales in particular. (Issue 23747)
• Fixed issue where dex complains about duplicate classes in cases where a Library Project depends on the same jar files or Java-only projects.
• Fixed issue where test projects had to independently reference the library projects used by an app project. Now referencing only the app project is enough

SDK Tools r17

General notes:

• Emulator
  • Added support for hardware accelerated graphics rendering. This feature requires an API Level 15, Revision 3 or later system image. (more info)Note: As of the SDK Tools Revision 17 release, the API Level 15, Revision 3 system image is not yet available.
  • Added support for running Android x86 system images in virtualization mode on Windows and Mac OS X. (more info)
  • Added experimental support for multi-touch input by enabing the emulator to receive touch input from a USB-tethered physical Android device. (more info)
• Added viewing of live detailed network usage of an app in DDMS. (more info)
• ProGuard
  • Updated the bundled ProGuard tool to version 4.7. In addition to many new features, this update fixes the Conversion to Dalvik format failed with error 1 error some users have experienced.
  • Updated the default proguard.cfg file with better default flags for Android.
  • Split the ProGuard configuration file has been in half, with project specific flags kept in project and the generic Android flags distributed (and updated) with the tools themselves.
• Build
  • Added a feature that allows you to run some code only in debug mode. Builds now generate a class called BuildConfig containing aDEBUG constant that is automatically set according to your build type. You can check the (BuildConfig.DEBUG) constant in your code to run debug-only functions.
  • Fixed issue when a project and its libraries include the same jar file in their libs folder.
  • Added support for custom views with custom attributes in libraries. Layouts using custom attributes must use the namespace URIhttps://schemas.android.com/apk/res-auto instead of the URI that includes the app package name. This URI is replaced with the app specific one at build time.
• Lint
  • Updated Lint to check Android application code. Lint rules which previously performed pattern based searches in the application code (such as the unused resource check) have been rewritten to use the more accurate Java-style parse trees.
  • Added support for checking library projects. This change means that rules such as the unused resource check properly handle resources declared in a library project and referenced in a downstream project.
  • Added ability to suppress Lint warnings in Java code with the new@SuppressLint annotation, and in XML files with the new tools: namespace and ignore attribute. (more info)
  • New Lint checks:
    • Added check for Android API calls that require a version of Android higher than the minimum supported version. You can use the new @TargetApi annotation to suppress warnings when the code is wrapped in a system version condition. (more info)
    • Added over 20 new Lint rules, including checks forperformance, XML layouts, manifest and file handling.
