最近一直在做android自动打包,之前已经完成了用纯命令行的形式打包、原生态ant脚本打包,和基于android的SDK的打包,并且实现了多渠道打包,后来同事推荐了gradle,网上的资料说gradle各种好,自己也感兴趣是实现一下,其实一般来说由于android对eclipse的支持减弱,大部分的人都是用gradle与android studio融合,这样面的例子也会比较多,但笔者所在的项目还是在eclipse的比较多,由于开发人员在移植过程中发现报错比较多所以一直没有完全移植(好吧,其实早晚会移植),所以笔者是用eclipse的IDE做的实验,下面先贴几个基础知识
首先是新建一个android项目,然后用自带的IDE生成gradle文件,具体参考http://blog.csdn.net/x605940745/article/details/41242687,有兴趣的同志们可以采取纯手写的方式,这种方式可以不依赖IDE,所以会比较好
这个是原始的build.gradle
代码语言:javascript复制buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.8. '
}
}
apply plugin: 'android'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
android {
compileSdkVersion 19
buildToolsVersion "19.0.3"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}
下面我先附上自己的build.gradle
代码语言:javascript复制buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12. '
}
}
apply plugin: 'android'
ant.importBuild 'build.xml' //这里导入了ant的脚本
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
android {
compileSdkVersion 19
buildToolsVersion "20.0.0"
signingConfigs { //签名,这里的文件名和密码是错的,后面还会有从外部导入的语句
myConfig {
//绝对路径和相对路径都可以
storeFile file("E:\keystore\mydemo.keystore") //签名文件
storePassword "276021750" //密码
keyAlias "mydemo.keystore"
keyPassword "111"
}
}
buildTypes{
release { //这里就是用来生成apk的步骤,具体看备注
//1.添加签名
signingConfig signingConfigs.myConfig
//2.runProguard 执行混淆代码
runProguard true
//混淆规则文件
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
}
}
productFlavors { //这里是多渠道的地方,AndroidManifest.xml文件里面要有标示,下面会贴文件
yingyongbao {
manifestPlaceholders = [ CHANNEL_NAME:"YINGYONGBAO"]
}
umeng {
manifestPlaceholders = [ CHANNEL_NAME:"UMENG" ]
}
wandoujia {
manifestPlaceholders = [ CHANNEL_NAME:"WANDOUJIA" ]
}
}
allprojects { //在这里是外部导入文件,然后更改本身文件的属性,这里只改了签名,还可以改其他的
afterEvaluate { project ->
def propsFile = rootProject.file('E:\keystore\keystore.properties')
def configName = 'myConfig'
if (propsFile.exists() && android.signingConfigs.hasProperty(configName)) {
def props = new Properties()
props.load(new FileInputStream(propsFile))
android.signingConfigs[configName].storeFile = file(props['storeFile'])
android.signingConfigs[configName].storePassword = props['storePassword']
android.signingConfigs[configName].keyAlias = props['keyAlias']
android.signingConfigs[configName].keyPassword = props['keyPassword']
}
}
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}
这里的具体功能看备注就可以了,暴力的贴上去就没问题,下面要贴几个文件,一个是AndroidManifest.xml文件,里面就是加了一行
代码语言:javascript复制 <meta-data
android:name="UMENG_CHANNEL"
android:value="${CHANNEL_NAME}" />
build.xml添加了一个target,用cmd命令写gradle deploy就可以执行里面的内容了
代码语言:javascript复制 <target name="deploy">
<!-- <replaceregexp flags="g" byline="true">
<regexp pattern="public static final Host host = Host.Development;" />
substitution expression 中是替换的值,替换的值都定义在相对应的配置文件中
<substitution expression="public static final Host host = Host.Test;" />
fileset 属性中的 dir 用来指定被替换文件所在的目录
includes 用来指定要替换哪个文件。
<fileset dir="./src/net/xtion/crm/base" includes="CrmAppContext.java" />
</replaceregexp> -->
<replace encoding="utf-8" dir="./src/com/example/learn723">
<include name="MainActivity.java" />
<replacefilter token="public static final String host = "Host.Test";" value="public static final String host = "Host.abc";" />
</replace>
</target>
还有一个签名文件
代码语言:javascript复制storeFile=E:\keystore\mydemo.keystore
storePassword=276021750
keyPassword=276021750
keyAlias=mydemo.keystore

这样的好处我们可以看到,用ant专职改文件的信息,这里专门做多渠道的打包,可以分开,其实要做到全自动还有两步,一个是从svn自动获取,这个网上有很多的版本可以学习,另一个是用脚本修改build.gradle文件,动态变换签名(其实也可以做批量修改)和动态增加这些功能的代码,可以用shell,可以用python,各位用需要可以试一下
