android - 无法编译Android测试应用

Question

我决定尝试为 Android 编程。我开始了他们的教程，但无法运行第一个项目自动创建的应用程序。我怀疑我的电脑设置有误，但不知道在哪里搜索错误。

教程说到新建项目的目录运行ant debug。这会为我抛出一个错误:java.lang.NoClassDefFoundError: com.android.sdklib.internal.build.DebugKeyProvider。我怀疑 SDK 安装不正确，但不知道出了什么问题或如何修复它。

我的电脑运行 openSUSE 12.1 64 位。我安装了 Oracte JDK 版本 1.7.0_04，以及包括工具和平台 Android 4.0 和 4.0.3 的 Android SDK。安装后，我将android tools文件夹添加到我的路径环境中，并为我的手机添加了一个udev规则，但没有做进一步的定制。亚行看到我的手机，我可以用 ddms 截屏。我不使用 Eclipse。

我是否遗漏了设置的某些部分？我该如何解决这个问题？

更新 我找到一个mailing list discussion关于有同样问题的人。他通过在/usr/bin 中更新一个名为“keytool”的符号链接(symbolic link)来指向正确的文件来解决这个问题。我没有这样的链接，所以我创建了它。问题仍然存在。回答该主题的人建议 SDK 中可能缺少一个名为“jarutil.jar”的文件。我的 SDK 中没有这样的文件，即使从头开始重新安装也是如此。由于讨论已经超过一年，我什至不知道这样的文件是否应该出现在当前版本中。

这是 ant debug 命令的完整输出:

Oracle JDK rpm 不以 SuSE 的方式配置 Java。特别是，您的 JAVA_HOME 可能设置不正确。

试试 JAVA_HOME=/usr/java/default ant debug。

还要确保 readlink -f `which java` 指向您的 Oracle JDK

看来您可以在 /etc/java/java.conf 中永久设置 JAVA_HOME

Apache Ant 手册建议使用以下方式设置 ant 需要的环境变量:

export ANT_HOME=/usr/local/ant
export JAVA_HOME=/usr/local/jdk-1.5.0.05
export PATH=${PATH}:${ANT_HOME}/bin 

其中jdk号应该指向电脑上安装的JDK号。这也永久设置变量。
