improved build.xml for Android SDK r16

    <!--
        This build file is imported by the project build file. It contains
        all the targets and tasks necessary to build Android projects, be they
        regular projects, library projects, or test projects.

        At the beginning of the file is a list of properties that can be overridden
        by adding them to your ant.properties (properties are immutable, so their
        first definition sticks and is never changed).

        Follows:
        - custom task definitions,
        - more properties (do not override those unless the whole build system is modified).
        - macros used throughout the build,
        - base build targets,
        - debug-specific build targets,
        - release-specific build targets,
        - instrument-specific build targets,
        - test project-specific build targets,
        - install targets,
        - help target
