Android Studio 插件中的 NullPointerExcepton Android 支持 [英] NullPointerExcepton in Android Studio plugin Android Support

问题描述

我在 Android Studio 插件 Android 支持中遇到以下异常.

I am getting the following exception in Android Studio plugin Android Support.

为了摆脱这个错误，我将 Android Studio 更新到了 14.1，但 Studio 只是构建了应用程序而不是运行它.

To get out of this error, I updated the Android Studio to 14.1, but studio just builds the app but not runs it.

推荐答案

为什么会这样

at  com.android.sdklib.internal.avd.AvdManager.parseAvdInfo(AvdManager.java:1616)

错误似乎出在 Android SDK 库中 Android 虚拟设备管理器.它试图打开一个文件，而 File 构造函数中的某些参数为空.

The error seems to be in Android SDK library Android Virtual Device Manager. It tries to open a file, and some argument in File constructor is null.

我再次安装了所需的插件..它工作了

I installed the needed plugins again..and it works

在类似情况下还能做什么:

1. 插件损坏 -> 重新安装插件.
2. SDK 损坏 -> 重新安装 Android SDK.
3. 使用了错误的版本 -> 检查使用的版本或更新 Android SDK.
