使用命令 cocos new HelloWorldLua -l lua -p com.jitongshidai.helloworldlua
创建了一个helloworld工程
用android studio 打包到手机上，运行很慢。LOGO 差不多需要一分钟才能显示。
看了下日志 是加载lua文件导致LOGO 需要等半天才能显示。

gradle.properties文件信息：
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

Specifies the JVM arguments used for the daemon process.
The setting is particularly useful for tweaking memory settings.
Default value: -Xmx10248m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
When configured, Gradle will run in incubating parallel mode.
This option should only be used with decoupled projects. More details, visit

Android SDK version that will be used as the compile project
PROP_COMPILE_SDK_VERSION=27
Android SDK version that will be used as the earliest version of android this application can run on
PROP_MIN_SDK_VERSION=15
Android SDK version that will be used as the latest version of android this application has been tested on
PROP_TARGET_SDK_VERSION=27
Android Build Tools version that will be used as the compile project
PROP_BUILD_TOOLS_VERSION=27.0.3
List of CPU Archtexture to build that application with
Available architextures (armeabi-v7a | arm64-v8a | x86)
To build for multiple architexture, use the : between them
Example - PROP_APP_ABI=armeabi-v7a:arm64-v8a:x86
PROP_APP_ABI=armeabi-v7a
android native code build type
none, native code will never be compiled.
cmake, native code will be compiled by CMakeLists.txt

说明：在比较老的机型上运行hellowrold 工程 都显示的很慢。
以前老版本的引擎创建出来的helloworld工程 运行都是秒显示的。
