Error:Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at http://gradle.org/docs/1.12/userguide/gradle_daemon.html

I had the same issue, it was because I had an existing ".gradle" folder and then I've played with the android studio version (and also with the Java jdk version) , and I guess it messed things up.
我遇到了同样的问题，这是因为我有一个现有的“.gradle”文件夹，然后我使用了 android studio 版本（以及 Java jdk 版本），我想它把事情搞砸了。
Solution: Remove the .gradle directory (mine's location was C:\Users\UserName\.gradle), and restart android studio. It will automatically create a new one.
解决方法：删除.gradle目录（我的位置是C:\Users\UserName\.gradle），重启android studio。它会自动创建一个新的。

Try adding -Xmx512min Android Studio->Settings->Compiler->VM Optionsas in below image.
尝试添加-Xmx512m的Android Studio->Settings->Compiler->VM Options，如下面的图像。
Reason for this issue could be:Grade's build daemon ( forked process ) is invoked with maximum Java heap size as platform defaultvalue. On a 32 bit Windows this system this could be as high as 1GB. We get this error message, if that much(default) heap size cannot be allocated to the build deamon. So use the -Xmxoption to set a lower heap size. It is not necessary to stick to -Xmx<size>with size as 512m. In my Win 32bit, 4GB RAM machine, -Xmx768mwas also good enough.
此问题的原因可能是：使用最大 Java 堆大小作为平台默认值调用 Grade 的构建守护程序（分叉进程）。在 32 位 Windows 上，此系统可能高达 1GB。如果无法将那么多（默认）堆大小分配给构建守护程序，我们会收到此错误消息。因此，使用该-Xmx选项设置较低的堆大小。没有必要坚持-Xmx<size>大小为512m。在我的 Win 32bit、4GB RAM 机器上，-Xmx768m也足够好。

I had the same problem, what i found was that Android Developer tools doesn't work well with JDK 8. I deleted my current JDK 8 and and installed JDK 7 and worked just like that no increase of heap memory or delete of .gradle folder.
我遇到了同样的问题，我发现 Android 开发人员工具不能与 JDK 8 配合使用。我删除了当前的 JDK 8 并安装了 JDK 7，并且没有增加堆内存或删除 .gradle 文件夹.

它主要适用于初始化虚拟机问题。
