android如何[dependency] API <= 15：将注解.jar添加到类路径

Question

I compile android project through "ant debug" .( http://developer.android.com/training/basics/firstapp/starting-activity.html )**

...
-build-setup:
     [echo] Resolving Build Target for MyFirstApp...
[gettarget] Project Target:   Android 2.3.3
[gettarget] API level:        10
     [echo] ----------
     [echo] Creating output directories if needed...
    [mkdir] Created dir: D:\myproj\android\MyFirstApp\bin
    [mkdir] Created dir: D:\myproj\android\MyFirstApp\bin\res
    [mkdir] Created dir: D:\myproj\android\MyFirstApp\gen
    [mkdir] Created dir: D:\myproj\android\MyFirstApp\bin\classes
    [mkdir] Created dir: D:\myproj\android\MyFirstApp\bin\dexedLibs
     [echo] ----------
     [echo] Resolving Dependencies for MyFirstApp...
[dependency] Library dependencies:
[dependency] No Libraries
[dependency]
[dependency] ------------------
[dependency] API<=15: Adding annotations.jar to the classpath.
     [echo] ----------
     [echo] Building Libraries with 'debug'...
   [subant] No sub-builds to iterate on

I found the annotations.jar under ${sdk}\\tools\\support and trace the build.xml under ${sdk}\\tools\\ant\\build.xml hereunder

<echo level="info">Resolving Dependencies for ${ant.project.name}...</echo>
        <dependency
                libraryFolderPathOut="project.library.folder.path"
                libraryPackagesOut="project.library.packages"
                libraryManifestFilePathOut="project.library.manifest.file.path"
                libraryResFolderPathOut="project.library.res.folder.path"
                libraryBinAidlFolderPathOut="project.library.bin.aidl.folder.path"
                libraryRFilePathOut="project.library.bin.r.file.path"
                libraryNativeFolderPathOut="project.library.native.folder.path"
                jarLibraryPathOut="project.all.jars.path"
                targetApi="${project.target.apilevel}"
                verbose="${verbose}" />

HOW TO ADD annotation.jar TO THE CLASSPATH? PS:I have added annontation.jar under D:\\myproj\\android\\MyFirstApp\\libs ,But still report that message.

Answer 1

In your Android manifest xml change the minimum SDK Version it requires API Level 15

<uses-sdk
        android:minSdkVersion="10"
 />

to

<uses-sdk
        android:minSdkVersion="15"
/>

Because the dependecy is API level 15
