Gradle use in Android Studio

A) Basic configuration

1. Build configuration

   buildscript { repositories {     jcenter()  } dependencies {     ‘com.android.tools.build:gradle:1.2.3‘ } }

   Android script

   apply plugin: ‘com.android.application‘

   Android configuration

   22 buildToolsVersion "22.0.1"}

   Project structure

   myapp├──build.gradle├──settings.gradle└── app├──build.gradle├── build├──libs└──src└── main├──java│└──com .package.myapp└──res├──drawable├──layout└──etc.      

3. Gradle wrapper structure (these new items are added to the user and do not need to be added again)

   myapp/ ├── gradlew  ├── gradlew.bat └── gradle/wrapper/     ├── gradle-wrapper.jar     └── gradle-wrapper.properties

   Run Build task-list all available tasks

   $ ./gradlew tasks

   Generating app-debug.apk Tasks

   $ ./gradlew assembleDebug# Apk路径: MyApp/app/build/ outputs/apk

4. Manually import the Eclipse-android project (Auto Import please click "Next" for consecutive points)
   Create the Build.gradle file under the project path:

   Buildscript {repositories {jcenter ()} dependencies {Classpath ' com.android.tools.build:gradle:1.2.3 '}} Apply plugin:  ' com.android.application ' Android {compilesdkversion 22 buildtoolsversion  "22.0.1"  Sourcesets {main {manifest.srcfile  ' androidmanifest.xml ' java.srcdirs = [ ' src '] resources.srcdirs = [ ' src '] aidl.srcdirs = [ ' src '] renderscript.srcdirs = [ ' src '] res.srcdirs = [ ' Res '] Assets.srcdirs = [ ' assets ']} androidtest.setroot ( ' tests ')}} dependencies {Compile Filetree (dir:  ' Libs ', include: [ ' *.jar ']) }

   PS can also copy and paste the source code of the Eclipse-android project into the project in Android Studio

II) Custom Configuration

1. Gradle ALL file Structures

   MyApp├── build.gradle├── settings.gradle└── app └── build.gradle

   Settings.gradle

   include ‘:app‘

   Myapp/build.gradle

   buildscript { repositories {     jcenter() } dependencies {     ‘com.android.tools.build:gradle:1.2.3‘ } }allprojects { repositories {     jcenter()  }}

   Myapp/app/build.gradle

   ApplyPlugin  ' com.android.application ' Android {compilesdkversion 22 buildtoolsversion  "22.0.1" Defaultconfig {ApplicationID  "com.gradleforandroid.gettingstarted" minsdkversion 14 targetsdkversion Span class= "Hljs-number" >22 versioncode 1 versionname  "1.0"} Buildtypes {release {minifyenabled false proguardfiles getdefaultproguardfile ( ' Proguard-android.txt '),  ' Proguard-rules.pro '}}}dependencies { Compile filetree (dir:  ' Libs ', include: [ ' *.jar ']) compile  ' com.android.support:appcompat-v7:22.2.0 '}     

3. Basic tasks

   $ ./gradlew assemble -为所有构建类型创建apk$ ./gradlew check 运行所有的检查，比如说Android Lint，如果发现问题可终止任务$ ./gradlew build 运行以上两个任务$ ./gradlew clean -清除生成的apk++++$ ./gradlew connectedCheck - 在设备上运行测试$ ./gradlew deviceCheck - 远程设备运行测试$ ./gradlew installDebug/installRelease - 在设备商安装指定版本$ ./gradlew uninstall - 卸载

   
   

4. Build types parameter settings for different versions-Buildconfig/resource Value

   Android {buildtypes {debug {Buildconfigfield "string",  "Api_url",  "\"/http Test.example.com/api\ "" Buildconfigfield  "boolean",  "LOG_HTTP _calls ", " true "Resvalue " string ", " App_name ", " Example DEBUG "} release {Buildconfigfield " string ",  "Api_url",  "\" Http://example.com/api\ "" Buildconfigfield " Span class= "Hljs-string" > "boolean",  "Log_http_calls",  "string",  "App_name",                

6. Global Settings (Build.gradle of the project root directory)

   allprojects {  ‘com.android.application‘  android {      compileSdkVersion 22      buildToolsVersion "22.0.1"  } }

   Setting Global parameters

   ext {  22  buildToolsVersion = "22.0.1"}

   Using Parameters in Myapp/app/build.gradle

   {  compileSdkVersion rootProject.ext.compileSdkVersion  buildToolsVersion rootProject.ext.buildToolsVersion}

8. Default task (Myapp/build.gradle)

   ‘clean‘, ‘assembleDebug‘

III) Dependency Management

2. Warehouse
   Preset Configuration Warehouse

   { mavenCentral() jcenter() mavenLocal()}

   Remote Warehouse

   repositories { maven {     "http://repo.acmecorp.com/maven2"     credentials {         username ‘user‘        password ‘secretpassword‘     } } ivy {     url "http://repo.acmecorp.com/repo" }}

   Local Warehouse

   repositories { maven {     "../repo" }}

3. Local dependency
   Project file dependencies

   dependencies {  ‘libs‘, include: [‘*.jar‘])}

   The structure and configuration of the native library

   # 结构：app ├── AndroidManifest.xml └── jniLibs     ├── armeabi     │   └── nativelib.so     ├── armeabi-v7a     │   └── nativelib.so     ├── mips     │   └── nativelib.so     └── x86         └── nativelib.so# 配置：android {  sourceSets.main {      jniLibs.srcDir ‘src/main/libs‘  }}

   Libray Project

   # 修改Android插件：apply plugin: ‘com.android.library‘# settings.gradle新增libray项目：include ‘:app‘, ‘:library‘# app内引用library项目：dependencies { compile project(‘:library‘)}

5. Dependency concept

Five) Multi-module construction management

1. Accelerate Build

   在gradle.properties里面添加：org.gradle.parallel=true

VI) Testing

1. Unit Test
   Using JUnit

   # 结构：app└─── src├─── main│ ├─── java     │    │    └─── com.example.app     │    └───res     └─── test          └─── java               └─── com.example.app# 依赖：dependencies { testCompile ‘junit:junit:4.12‘}

   Using robolectric

   # dependency: ApplyPlugin' Org.robolectric ' dependencies {compile filetree (Dir' Libs ',Include: [' *.jar ']) compile' com.android.support:appcompat-v7:22.2.0 ' Testcompile' Junit:junit:4.12 ' Testcompile' org.robolectric:robolectric:3.0 ' Testcompile' org.robolectric:shadows-support:3.0 '}# Demo:@RunWith (Robolectrictestrunner.Class@Config (manifest ="App/src/main/androidmanifest.xml", SDK =18) public class mainactivitytest { @Test public void Clickingbuttonshouldchangetext () {appcompatactivity activity = robolectric.buildactivity (mainactivity.class). Create (). get (); button button = (button) Activity.findviewbyid (r.id.button); textview TextView = (textview) Activity.findviewbyid (r.id.label); Button.performclick (); Assertthat (Textview.gettext (). toString (), Equalto (activity.getstring (R.string.hello (_robolectric))); } }

3. Functional Testing
   Using Espresso

1. <待续>

Eight) Configure CI

1. <待续>

IX) Custom configuration-Advanced

2. Reduce apk file size
   Using Proguard

   android { buildTypes {     release {         true         proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘     } } }

   Shrink resource file-auto (< manual to Be continued >)

   android { buildTypes {     release {         true         shrinkResources true     } } }

3. Accelerate Build

   org.gradle.parallel=true # 并行构建org.gradle.daemon=true # 开启Gradle守护进程org.gradle.jvmargs=-Xms256m -Xmx1024m # 配置JVM<参照>

   
   

   
   Using Profiling

   <待续>

   Using Jack (Java Android Compiler Kit) and Jill (Jack Intermediate Library Linker)

   <待续>

5. Ignore Lint

   android {  lintOptions {      false  }}

7. Using Ant

   <待续>

9. App Pack-Advanced
   Split apk

   android {  splits {      density {          enable true          exclude ‘ldpi‘, ‘mdpi‘          compatibleScreens ‘normal‘, ‘large‘, ‘xlarge‘ } } }生成结果：app-hdpi-release.apkapp-universal-release.apkapp-xhdpi-release.apkapp-xxhdpi-release.apkapp-xxxhdpi-release.apk
