gradle – Trac

项目转换为gradle http://tools.android.com/tech-docs/new-build-system/intellij_to_gradle
gradle android 详细说明 http://tools.android.com/tech-docs/new-build-system/user-guide

常用配置

apply plugin: 'java': 指定项目为java项目
apply plugin: 'android' 指定为android项目 apply plugin: 'android-library':增加android库项目

常用命令

gradle -q quite模式，出错才输出

gradle tasks --all 列出所有任务

gradle projects 列出当前目录下所以项目

gradle :app:tasks 例如 gradle test:assemble 运行test项目assemble任务，相关前置任务会检查一次

例子

以聚超值为例子，因为要多个项目构成，需要settings.gradle 这个文件，参考

settings.gradle

include ':pcgCommon', ':Juchaozhi'

local.properties ,用于配置sdk.dir

sdk.dir=/Volumes/DATA/tools/android-sdk-macosx

root项目下有两个项目 pcgCommon和Juchaozhi
root 项目build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }

注意事项

要注意有些旧项目的AndroidManifest.xml不符合新的规范要加上 useOldManifestMerger true 这个参数

检查的时候有问题也跳过
lintOptions {
abortOnError false
}

runProguard true 代码混淆的选项参考

市场列表文件每一行代表一个市场渠道

版本信息用正则匹配 AndroidManifest?.xml 这个文件

市场替换的代码 line.replaceAll("MOFANG_CHANNEL_VALUE", "$market")，设置manifestFile文件 variant.processResources.manifestFile

只编译release 可以采用 gradle assembleRelease

调过lint
tasks.whenTaskAdded { task ->
if (task.name.equals("lint")) {
task.enabled = false
}
}

复制so文件到安装包要怎加这个，只有在app模块生效在lib模块不生效 jniLibs.srcDirs = ${rootDir}/pcgCommon/libs?

lint 和 Proguard

proguard官方说明
打开注释 runProguard true ，修改proguard.txt可以打开混淆选项，如果内存不够，修改gradle.properties增加java运行内存
混淆的时候要注意JAVA_HOME版本和proguard支持的java版本相符

参考例子 http://www.eoeandroid.com/blog-1287430-48429.html

    buildTypes{
        release {
            signingConfig  signingConfigs.myConfig
            runProguard true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), "${rootDir}/proguard.txt"
        }
    }

sdk里面提供的proguard-android-optimize.txt大致为

-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
-optimizationpasses 5
-allowaccessmodification
-dontpreverify
-dontusemixedcaseclassnames

}
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

lint常见问题
主要是api版本和部分资源没使用的问题
InlinedApi?: Using inlined constants on older versions
NewApi?: Calling new methods on older versions
UnusedResources?: Unused resources
