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 https://docs.gradle.org/4.1/userguide/gradle_daemon.html
Please read the following process output to find out more:

Error occurred during initialization of VM
Could not reserve enough space for 1048576KB object heap

　　解决办法：

　　编辑studio.exe.vmoptions文件将 Android Studio 的最大堆内存减小至 512Mb。

　　 vmoptions文件路径： Android Studio安装目录/bin/studio.exe.vmoptions 或 studio64.exe.vmoptions

　　studio.exe.vmoptions        32位

　　studio64.exe.vmoptions    64位

　　针对低内存机器配置IDE　

　　修改gradle.properties文件 org.gradle.jvmargs=-Xmx512m ，路径：Project>Android>Gradle Scripts>gradle.properties。

改完之后是这个样子：

# Project-wide Gradle settings.
 
# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.

org.gradle.jvmargs=-Xmx512m
 
# When configured, Gradle will run in incubating parallel mode.
