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
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. # For more details on how to configure your build environment visit # http://www.gradle.org/docs/current/userguide/build_environment.html # Specifies the JVM arguments used for the daemon process. # The setting is particularly useful for tweaking memory settings. org.gradle.jvmargs=-Xmx512m # When configured, Gradle will run in incubating parallel mode. # This option should only be used with decoupled projects.
