上次的总结已过了一段时间，这次细说当中的解析manifest模块 涉及到三块功能
# 一、解析manifest
# 二、maven生成JAR包
# 三、Ant执行调用解析方法
一、解析manifest
使用JAVA实现解析方法，并生成可执行jar包 最终通过shell命令执行解析动做，这里不做详细解释只贴出两部分代码 以做备忘。
1、做为外部使用shell命令的出口代码：
public class AndroidManifestRewriter {
public static void main(String[] args) throws IOException {
try{
Args argList = Args.parseArgs(args);
if(argList == null) {
System.out.println( "java -jar axml-io.jar -i xxx -o xxx ...");
System.exit(0);
}
new AndroidManifestRewriter().rewrite(new File(argList.mInManifest), new File(argList.mOutManifest), argList.mVersionCode, argList.mVersionName, argList.mChannelValue);
}catch(Exception e){
e.printStackTrace();
}
}
private void rewrite(File source, File target, String versionCode, String versionName, String channelValue) throws IOException {
final AndroidManifest manifest = new AndroidManifest(source);
System.out.println("Gefunden: versionName='" + manifest.getVersionName() + "', versionCode=" + manifest.getVersionCode() + ", "+ manifest.getChannelName() + ":" + manifest.getChannelValue() + "," + manifest.getChannelGTName() + ":" + manifest.getChannelGTValue());
manifest.validate(source);
if (versionName != null) {
manifest.setVersionName(versionName);
}
if (versionCode != null) {
manifest.setVersionCode(Integer.parseInt(versionCode));
}
if (channelValue != null) {
manifest.setChannelValue(channelValue);
}
if (channelValue != null && manifest.getChannelGTName() != null){
manifest.setChannelGTValue(channelValue);
}
System.out.println("Gefunden: versionName='" + manifest.getVersionName() + "', versionCode=" + manifest.getVersionCode() + ", "+ manifest.getChannelName() + ":" + manifest.getChannelValue() + "," + manifest.getChannelGTName() + ":" + manifest.getChannelGTValue());
manifest.write(target);
}
static class Args {
public String mInManifest = null;
public String mOutManifest = null;
public String mVersionCode = null;
public String mVersionName = null;
public String mChannelValue = null;
public static Args parseArgs(String[] args) {
Args argList = new Args();
Options options = new Options();
options.addOption("h", "help", false, "Print this usage information");
options.addOption("i", "in", true, "Type a input AndroidManifest.xml file" );
options.addOption("o", "out", true, "Type a output AndroidManifest.xml file" );
options.addOption(null, "versionCode", true, "Modify android:versionCode by input value" );
options.addOption(null, "versionName", true, "Modify android:versionName by input value" );
options.addOption(null, "channelValue", true, "Modify meta-data:channelValue by input value" );
CommandLineParser parser = new BasicParser();
CommandLine commandLine = null;
try {
commandLine = parser.parse( options, args );
} catch (ParseException ex) {
System.err.println(ex.getMessage());
System.out.println( "java -jar axml-io.jar -i xxx -o xxx ...");
System.exit(0);
}
boolean cmdFound = false;
if( commandLine.hasOption("h") ) {
System.out.println( "java -jar axml-io.jar -i xxx -o xxx ...");
System.exit(0);
}
if( commandLine.hasOption("i") ) {
argList.mInManifest = commandLine.getOptionValue("i");
cmdFound = true;
}
if( commandLine.hasOption("o") ) {
argList.mOutManifest = commandLine.getOptionValue("o");
cmdFound = true;
}
if( commandLine.hasOption("versionCode") ) {
argList.mVersionCode = commandLine.getOptionValue("versionCode");
cmdFound = true;
}
if( commandLine.hasOption("versionName") ) {
argList.mVersionName = commandLine.getOptionValue("versionName");
cmdFound = true;
}
if( commandLine.hasOption("channelValue") ) {
argList.mChannelValue = commandLine.getOptionValue("channelValue");
cmdFound = true;
}
if (cmdFound == false) {
System.out.println( "java -jar axml-io.jar -i xxx -o xxx ...");
System.exit(0);
}
return argList;
}
}
}
此处代码 将与maven生成所用到的 pom.xml相关，做为可执行jar包
2、解析后替换清单文件中相关的KEY-VALUE值，因为这次总结 主要源于打包后台需求有修改，不只使用友盟上报统计，又增加了个额外的统计SDK 他自有一套统计SDK，并有独立的meta 定义渠道名称，相应的 在解析时对渠道多了一个维度的修改，主要需要修改的代码如下：
AndroidManifest.java
private ResXmlAttribute(ResSource src) {
this.namespace = new ResStringPoolRef(src);
this.name = new ResStringPoolRef(src);
this.rawValue = new ResStringPoolRef(src);
this.typedValue = new ResValue(src);
if ("http://schemas.android.com/apk/res/android".equals(this.namespace.lookup())) {
if (-1 == versionCode && "versionCode".equals(name.lookup())) {
versionCode = typedValue.asInt();
isVersionCode = true;
} else if (null == versionName && "versionName".equals(name.lookup())) {
versionName = typedValue.asString();
isVersionName = true;
} else if (null == channelName && "UMENG_CHANNEL".equals(rawValue.lookup())) {
channelName = typedValue.asString();
} else if (null == channelGTName && "GT_INSTALL_CHANNEL".equals(rawValue.lookup())) {
channelGTName = typedValue.asString();
} else if (null == channelValue && null != channelName) {
channelValue = typedValue.asString();
isChannelValue = true;
}else if (null == channelGTValue && null != channelGTName) {
channelGTValue = typedValue.asString();
isChannelGTValue = true;
}
}
}
public void writeTo(ResTarget tgt) {
this.namespace.writeTo(tgt);
this.name.writeTo(tgt);
if (isVersionName && versionNameChanged) {
long newIndex = stringPool.getIndexOfNewVersionName();
this.rawValue.writeTo(tgt, newIndex);
typedValue.writeToWithNewVersionIndex(tgt, newIndex);
} else if (isVersionCode && versionCodeChanged) {
this.rawValue.writeTo(tgt);
typedValue.writeToWithNewVersionCode(tgt);
} else if (isChannelValue && channelValueChanged) {
long newIndex = stringPool.getIndexOfNewChannelValue();
this.rawValue.writeTo(tgt, newIndex);
System.out.println("getIndexOfNewChannelValue:"+newIndex);
typedValue.writeToWithNewChannelIndex(tgt, newIndex);
} else if (isChannelGTValue && channelValueChanged) {
long newIndex = stringPool.getIndexOfNewChannelGTValue();
this.rawValue.writeTo(tgt, newIndex);
System.out.println("getIndexOfNewChannelGTValue:"+newIndex);
typedValue.writeToWithNewChannelIndex(tgt, newIndex);
} else {
this.rawValue.writeTo(tgt);
typedValue.writeTo(tgt);
}
}
AndroidManifestRewriter.java
private void rewrite(File source, File target, String versionCode, String versionName, String channelValue) throws IOException {
final AndroidManifest manifest = new AndroidManifest(source);
System.out.println("Gefunden: versionName='" + manifest.getVersionName() + "', versionCode=" + manifest.getVersionCode() + ", "+ manifest.getChannelName() + ":" + manifest.getChannelValue() + "," + manifest.getChannelGTName() + ":" + manifest.getChannelGTValue());
manifest.validate(source);
if (versionName != null) {
manifest.setVersionName(versionName);
}
if (versionCode != null) {
manifest.setVersionCode(Integer.parseInt(versionCode));
}
if (channelValue != null) {
manifest.setChannelValue(channelValue);
}
if (channelValue != null && manifest.getChannelGTName() != null){
manifest.setChannelGTValue(channelValue);
}
System.out.println("Gefunden: versionName='" + manifest.getVersionName() + "', versionCode=" + manifest.getVersionCode() + ", "+ manifest.getChannelName() + ":" + manifest.getChannelValue() + "," + manifest.getChannelGTName() + ":" + manifest.getChannelGTValue());
manifest.write(target);
}
GT_INSTALL_CHANNEL 的增加 引起的channelGTName，channelGTValue，isChannelGTValue，getIndexOfNewChannelGTValue（）一系列变量、方法的增加。
二、maven生成JAR包，
解析方法完成后，切换到 项目工程目录下，包含pom.xml文件的目录下
image.png
执行命令：mvn assembly:assembly 会生成可执行JAR包。
关于pom.xml有两处需要注意下 XML文件如下
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>idotools</groupId>
<artifactId>axml-io</artifactId>
<version>1.0.2</version>
<dependencies>
<dependency>
<groupId>commons-cli</groupId>
<artifactId>commons-cli</artifactId>
<version>1.2</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<plugin>
<!-- <artifactId>maven-jar-plugin</artifactId> -->
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>libs/</classpathPrefix>
<mainClass>idotools.axml.io.AndroidManifestRewriter</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
其中
<version>1.0.2</version> 代表JAR的版本号；
<mainClass>idotools.axml.io.AndroidManifestRewriter</mainClass> 代表可执行入口类名称。
就此 解析方法修改完成，接下来实现使用ant 在build.xml中配置此可执行jar包，实现批量打包。
三、Ant执行调用解析方法
<target name="change-channel" if="has.channel" >
<echo level="info">New Channel umeng: ${CHANNEL}</echo>
<exec dir="${apk.obj.dir}" executable="${utils.dir}/axmlio" >
<arg value="-i" />
<arg value="${apk.obj.dir}/AndroidManifest.xml" />
<arg value="-o" />
<arg value="${apk.obj.dir}/AndroidManifest.xml.tmp" />
<arg value="--channelValue" />
<arg value="${CHANNEL}" />
</exec>
<move file="${apk.obj.dir}/AndroidManifest.xml.tmp" tofile="${apk.obj.dir}/AndroidManifest.xml" overwrite="true" />
</target>
以上是build.xml中对渠道的替换配置，可以见到 执行axmlio shell命令，其中参数 -i -o --channelValue 与可执行JAR中的AndroidManifestRewriter相关。以下只做参考
static class Args {
public String mInManifest = null;
public String mOutManifest = null;
public String mVersionCode = null;
public String mVersionName = null;
public String mChannelValue = null;
public static Args parseArgs(String[] args) {
Args argList = new Args();
Options options = new Options();
options.addOption("h", "help", false, "Print this usage information");
options.addOption("i", "in", true, "Type a input AndroidManifest.xml file" );
options.addOption("o", "out", true, "Type a output AndroidManifest.xml file" );
options.addOption(null, "versionCode", true, "Modify android:versionCode by input value" );
options.addOption(null, "versionName", true, "Modify android:versionName by input value" );
options.addOption(null, "channelValue", true, "Modify meta-data:channelValue by input value" );
CommandLineParser parser = new BasicParser();
CommandLine commandLine = null;
try {
commandLine = parser.parse( options, args );
} catch (ParseException ex) {
System.err.println(ex.getMessage());
System.out.println( "java -jar axml-io.jar -i xxx -o xxx ...");
System.exit(0);
}
boolean cmdFound = false;
if( commandLine.hasOption("h") ) {
System.out.println( "java -jar axml-io.jar -i xxx -o xxx ...");
System.exit(0);
}
......
}
也可以切换到utils下执行
./axmlio -i AndroidManifest.xm -o AndroidManifest.xml.tmp --channelValue mumay
shell 文件axmlio 内容如下：

这篇文章因为是接手项目，所以这里所做总结主要是为了备忘，很多地方写的并不通顺，也不包含细节讲解 原因也在于并不是很熟悉这块的开发
