• 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 upgrade new features, this update fixes
    Conversion to Dalvik format failed with error 1Error some users have experienced.
  • Updated the defaultproguard.cfgFile 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
    BuildConfigContainingDEBUGConstant that is automatically set according to your build type. You can check (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. (More Info)

    http://schemas.android.com/apk/res-autoInstead of the URI that includes des 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 previusly specified med 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@SuppressLintAnnotation, and in XML files with the new tools: namespace and ignore attribute. (More Info)
  • New lint checks:
    • Added check for Android api cils that require a version of Android higher than the minimum supported version. You can use the new
      @TargetApiAnnotation to suppress warnings when the code is wrapped in a system version condition. (More Info)
    • Added over 20 new lint rules, including checks
      Performance, XML layouts, manifest and file handling.
