gradle grammar
Development environment android studio 3.4.1
gradle version 5.1.1
What is gradle
gradle in writing AndroidStudio
Write the following files in the main module gradle project:
You will enter the following information in the console log:
gradle unified multi-module configuration code
Exercise gradle
Preparation: Create an app project, making the project contains app modules and library modules.
Requirements: to unify the various modules are common configuration by creating a new gradle file.
Steps:
In the root directory of the project, the new configuration file named config.gradle, and in the project root directory, the introduction of the profile.
test:
Declare properties in config.gradle the username. And gradle module lirary uses username attribute, compile the project, view the output log information.
config.gradle文件内容如下：
//添加多个自定义属性，可以使用ext代码块
ext{
username = "zfc"
}
lirarymodule下的build.gradle内容如下:
...
println "${username}"
rootProject.ext.username = 1234
println "${rootProject.ext.username}"
...
Compile the project was as follows:
Extraction unified configuration
//声明变量
isRelease = true
//打印变量的值
print isRelease
//定义字典
androidId=[
compileSdkVersion:29,
buildToolsVersion:"29.0.2",
applicationId:"com.canjun.components",
minSdkVersion:22,
targetSdkVersion:29,
versionCode:1,
versionName:"1.0"
]
appId = [
"app":"com.canjun.components",
"order":"com.canjun.components.order",
"personal":"com.canjun.components.personal"
]
url = [
debug: "https://10.1.1.1/debug/rest",
release: "https://10.1.1.1/release/rest",
]
supportLirary = "28.0.1"
dependencies = [
appcompat:'androidx.appcompat:appcompat:1.1.0',
constraintlayout:'androidx.constraintlayout:constraintlayout:1.1.3'
]
Use of unified configuration config.gradle
apply plugin: 'com.android.application'
def androidId = rootProject.ext.androidId
def appId = rootProject.ext.appId
def support = rootProject.ext.dependencies
android {
compileSdkVersion androidId.compileSdkVersion
buildToolsVersion androidId.buildToolsVersion
defaultConfig {
applicationId appId.app
minSdkVersion androidId.minSdkVersion
targetSdkVersion androidId.targetSdkVersion
versionCode androidId.versionCode
versionName androidId.versionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
...
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
// implementation 'androidx.appcompat:appcompat:1.1.0'
// implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
// HashMap<String,String> map = new HashMap<>()
support.each{ k,v-> implementation v}
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}
Constant attribute set to the class BuildConfig
buildConfigFiled("String","debug","\"${url.debug}\"")
apply plugin: 'com.android.application'
...
def url = rootProject.ext.url
...
android {
...
buildTypes {
debug{ buildConfigField("String","debug","\"${url.debug}\"")
}
release {
buildConfigField("String","debug","\"${url.release}\"")
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
Results: debug field generated in the main module BuildConfig (App) directory

Components of significance
PhoneModule and Android Libray difference
PhoneModule存在的配置：
apply plugin: 'com.android.application'
applicationId "com.canjun.components"
AndroidLibrary存在的配置：
apply plugin: 'com.android.library'
applicationId "com.canjun.components"（x）
Integration and component
Integration is a project only one main module, other modules for Lirary, these Library not run alone. They must run together and become a master module app
Project means that one component of the respective module can be run separately.
Integrated for production, assembly and testing for the development of a multi-stage, the characteristics of highly decoupled in favor of development and testing.
Components of the project configuration

modifying the configuration of the main module gradle

3. Effect show
Centralized effects show:
Components effects show:
Temporary assembly of code development, when the centralized packaging dynamically isolated
Since the development of the component, write some localized moduel code of the response, but the code, but does not handle, the default will be packed into the main module. As shown below:
Therefore require special handling at:
- Configuration gradle, code isolation
- The localization code is stored in accordance with the configuration gradle
