解决方案

我有此相同的问题，昨晚终于找到了方法让仿真器开始工作：

与列出可用的目标：机器人列表的目标

Android的创建AVD -n（名称）-t {}目标ID （关于{名}我选择了平板电脑 - 相信其任意）

==仍然没有工作，但后来我发现=>

  

我右键单击上面的manifest.xml文件，选中的选项运行方式 - >   运行配置 - >上的标签目标，并选择AVD创建

Getting NullPointerException when trying to start avd. I just downloaded the ADT bundle for Mac and ran android avd. Anyone know why it would fail?

解决方案

I had this exact same problem last night and finally found the ways to get the emulator to start working:

List the available targets with: android list targets

android create avd -n {name} -t {targetID} (for {name} I chose Tablet - believe its arbitrary)

== Still wasn't working but then I discovered =>

I right-clicked above the manifest.xml file, selected option Run As -> Run Configurations -> on a tab Target, and selected AVD created.
