我正在使用 Eclipse IDE 开发 Android 开发工具，但无法正确运行我的应用程序。
当我调用运行配置时，我检索到以下空指针：
会话数据 - eclipse.buildId=v21.0.1-543035 java.version=1.7.0_13 java.vendor=Oracle Corporation BootLoader 常量：OS=win32, ARCH=x86, WS=win32, NL=en_US 框架参数：-product com. android.ide.eclipse.adt.package.product 命令行参数：-os win32 -ws win32 -arch x86 -product com.android.ide.eclipse。> adt.package.product-clean
