前言
自定义android studio插件?想想就觉得是一件令人兴奋的事。最近闲来无事决定完善之前的一些代码操作,然后就想到了之前的apk多渠道打包工具,觉得还是太麻烦,何不用插件的形式引入工程自动打包呢。说做就做...
资料整理
1.插件入门:http://blog.csdn.net/sbsujjbcy/article/details/50782830
2.插件进阶:AndroidComponent组件化方案,AndResGuard资源混淆库的插件源码
3.渠道包原理:将渠道打入assets里的文件中,我之前的文章有介绍过此原理的打包工具
简单流程图
BDB1A4CD-6D45-4470-BE5B-56F6A891BC69.pngejApkRelease task
1.初始化task
创建EjApkTask继承gradle api的DefaultTask来创建自己的task
public class EjApkTask extends DefaultTask{
def android
def buildConfigs = []
EjApkTask(){
description = 'Assemble ej APK'
group = 'andChannelApk'
outputs.upToDateWhen { false }
android = project.extensions.android
...
}
@TaskAction
run(){
...
}
}
其中:
group表示在android studio 右侧的gradle任务列表为此task创建一个自己的目录:
DB39201E-B335-4473-AD38-FD531407425B.png
会自动将大写转为小写,写法参照AndResGuard原码写的
run方法表示此task运行的方法
创建,并初始化ejApkRelease task
project.afterEvaluate {
System.out.println("ejApkRelease is start")
def taskName = "resguardRelease"
def ejTask = "ejApkRelease"
def task = project.task(ejTask, type: EjApkTask)
//判断是否存在resguardRelease task
if(project.tasks.findByPath(taskName) != null){
System.out.println("ejApkRelease is exit")
task.dependsOn "resguardRelease"
} else {
task.dependsOn "assembleRelease"
}
}
其中project.afterEvaluate闭包的调用位置实在 项目的settings.gradle构建之后,build.gradle构建之前。
task.dependsOn 表示将此任务task的调用位置放在resguardRelease或者assembleRelease task的后面
2.task逻辑处理
通过api 获取app-release.apk文件位置,获取gradle配置的签名文件,获取渠道文件的路径配置:
//渠道文件配置位置
String channel = project.properties.get("channelFile")
buildConfigs.each{ config ->
if (config.file == null || !config.file.exists()) {
System.out.println("ejApkRelease EjApkTask apk file not exit 1")
return
}
//签名文件
def signConfig = config.signConfig
//app-release.apk位置
String path = config.file.getAbsolutePath()
System.out.println("path:"+path)
InputParam.Builder builder = new InputParam.Builder()
.setChannel(channel)
.setInputFolder(useFolder(config.file))
.setApkPath(path)
.setSignFile(signConfig.storeFile)
.setKeypass(signConfig.keyPassword)
.setStorealias(signConfig.keyAlias)
.setStorepass(signConfig.storePassword)
InputParam inputParam = builder.build()
Main.gradleRun(inputParam)
}
其中:
project.properties.get() 表示获取运行项目(app)目录下的gradle.properties文件里面的配置
解压,修改渠道文件,打包签名
1.解压:
解压方式很简单,通过java自带api实现解压:
@SuppressWarnings("rawtypes")
public static HashMap<String, Integer> unZipAPk(String fileName, String filePath) throws IOException {
checkDirectory(filePath);
ZipFile zipFile = new ZipFile(fileName);
Enumeration emu = zipFile.entries();
HashMap<String, Integer> compress = new HashMap<>();
while (emu.hasMoreElements()) {
ZipEntry entry = (ZipEntry) emu.nextElement();
if (entry.isDirectory()) {
new File(filePath, entry.getName()).mkdirs();
continue;
}
BufferedInputStream bis = new BufferedInputStream(zipFile.getInputStream(entry));
File file = new File(filePath + File.separator + entry.getName());
File parent = file.getParentFile();
if (parent != null && (!parent.exists())) {
parent.mkdirs();
}
//要用linux的斜杠
String compatibaleresult = entry.getName();
if (compatibaleresult.contains("\\")) {
compatibaleresult = compatibaleresult.replace("\\", "/");
}
compress.put(compatibaleresult, entry.getMethod());
FileOutputStream fos = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fos, BUFFER);
byte[] buf = new byte[BUFFER];
int len;
while ((len = bis.read(buf, 0, BUFFER)) != -1) {
fos.write(buf, 0, len);
}
bos.flush();
bos.close();
bis.close();
}
zipFile.close();
return compress;
}
1.修改渠道文件:
先删除解压包存在的签名文件,再寻找assets文件夹是否存在,存在直接修改渠道文件,不存在则添加assets文件夹并添加渠道文件,通过渠道文件获取要打的渠道,循环修改,并打包,签名:
public void buildApk() throws Exception {
//删除签名文件
File sinFile = new File(tempFile,"META-INF");
if(sinFile.exists()){
FileZipUtils.deleteDir(sinFile);
System.out.println("删除原签名文件");
}
//存放签名包位置
File fileassets = new File(tempFile,"assets");
if(!fileassets.exists()){
fileassets.mkdirs();
}
File fileEjChannel = new File(fileassets,"ej_channel");
if(!fileEjChannel.exists()){
fileEjChannel.createNewFile();
}
//打包apk位置
File fileChannel = new File(fileApk,"channel");
if(fileChannel.exists()){
fileChannel.delete();
}
File unSinedFiles = new File(fileChannel,"unsign");
File sinedFiles = new File(fileChannel,"sign");
unSinedFiles.mkdirs();
sinedFiles.mkdirs();
File fileChannelTxt = new File(inputParam.channel);
if(!fileChannelTxt.exists()){
System.out.println("channel.txt not exit");
return;
}
//获取所有渠道
InputStream in = new FileInputStream(fileChannelTxt);
int size = in.available();
byte[] buffer = new byte[size];
in.read(buffer);
in.close();
String allChannel = new String(buffer, "utf-8");
//获取所有渠道数组
String[] channels = allChannel.split(",");
//循环渠道打包
for(String content : channels){
{
OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream(fileEjChannel),"UTF-8");
System.out.println("channel content:"+content);
//渠道名称加密
String channel = ChannelEncode.encode(content);
//不加密
// String channel = content;
System.out.println("channel:"+channel);
osw.write(channel, 0, channel.length());
osw.flush();
osw.close();
//压缩文件
File outApkUnsin = new File(unSinedFiles,"release-"+content+"-unsin.apk");
FileZipUtils.compress(tempFile,outApkUnsin);
//签名
File outApkSign = new File(sinedFiles,"release-"+content+"-sin.apk");
signWithV1sign(outApkUnsin,outApkSign);
}
}
}
使用方法
最后讲一下使用方式,由于本插件没有上传jcenter,所以需要下载下来编译一下,编译方式:
DCCFAA05-568A-45BB-B2AF-FD2CBB3BD15F.png
通过双击图中的uploadArchives 任务,会在项目的根目录创建本地maven仓库repo
1A8A8694-E18D-4774-9288-FADB8691311D.png
再在项目中引入此插件即可

55A09055-5C41-4965-9EC3-5684EC28F106.png
这是编译通过之后会在右侧出现:

任务,点击运行此任务即可打出渠道包
