Gradle Wrapper结构(这些新建项目时都添加给了用户,不需要重新添加)
myapp/
├── gradlew
├── gradlew.bat
└── gradle/wrapper/
├── gradle-wrapper.jar
└── gradle-wrapper.properties
运行build任务 - 列出所有可用任务
$ ./gradlew tasks
生成App-debug.apk任务
$ ./gradlew assembleDebug
# Apk路径: MyApp/app/build/ outputs/apk
手动导入Eclipse-Android项目(自动导入请连续点“下一步”)
在项目路径下创建build.gradle文件:
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 也可以复制粘贴Eclipse-Android项目的源代码到Android Studio的项目里
Gradle所有文件结构

buildscript {

minSdkVersion 14
targetSdkVersion 22

}
buildTypes {

}
}
}
dependencies {
compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])
compile ‘com.android.support:appcompat-v7:22.2.0‘
}
基础任务
$ ./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
Build Types不同版本的参数设置 - 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 "boolean", "LOG_HTTP_CALLS", "false"
resValue "string", "app_name", "Example"
}
}
}
全局设置(项目根目录的build.gradle)
allprojects {
apply plugin: ‘com.android.application‘
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
}
}
设置全局参数
ext {
compileSdkVersion = 22
buildToolsVersion = "22.0.1"
}
在MyApp/app/build.gradle里面使用参数
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
}
默认任务(MyApp/build.gradle)
defaultTasks ‘clean‘, ‘assembleDebug‘
仓库
预设配置仓库
repositories {
mavenCentral()
jcenter()
mavenLocal()
}
远程仓库
repositories {
maven {
url "http://repo.acmecorp.com/maven2"
credentials {
username ‘user‘
password ‘secretpassword‘
}
}
ivy {
url "http://repo.acmecorp.com/repo"
}
}
本地仓库
repositories {
maven {
url "../repo"
}
}
本地依赖

dependencies {
compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])

原生库结构与配置
# 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项目
# 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‘)
}
依赖概念
<待续>
Android Studio内添加依赖
<待续>
在gradle.properties里面添加:
org.gradle.parallel=true
单元测试
使用JUnit
# 结构:
app
└─── src
├─── main
│ ├─── java
│ │ └─── com.example.app
│ └───res
└─── test
└─── java
└─── com.example.app
# 依赖:
dependencies {
testCompile ‘junit:junit:4.12‘
}
使用Robolectric
# 依赖:
apply plugin: ‘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)));
}
}
功能测试
使用Espresso
<待续>
测试覆盖度
使用Jacoco
<待续>
<待续>
<待续>
android {
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘
}
}
}
收缩资源文件 - 自动 (<手动待续>)
android {
buildTypes {
release {
minifyEnabled true
shrinkResources true
}
}
}
加速构建
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<参照下图>
使用Profiling
<待续>
使用Jack(Java Android Compiler Kit) and Jill(Jack Intermediate Library Linker)
<待续>
忽略Lint
android {
lintOptions {
abortOnError false
}
}
使用Ant
<待续>
app打包 - 进阶
分割apk
android {
splits {
density {
enable true
exclude ‘ldpi‘, ‘mdpi‘
compatibleScreens ‘normal‘, ‘large‘, ‘xlarge‘
}
}
}
生成结果:
app-hdpi-release.apk
app-universal-release.apk
app-xhdpi-release.apk
app-xxhdpi-release.apk
app-xxxhdpi-release.apk
