AndroidStudio实现多渠道打包速度慢，且公司渠道多大54个（后面还会追加/(ㄒoㄒ)/~~），一到上线就需要各个渠道的apk，着实是慢，现在用自己编写的jar包来实现多渠道打包。
先看多渠道打包成果。

现在我们来实现多渠道的jar包吧。
1、首先新建一个Java Application，创建一个PackagingTool 工具类，添加如下代码。

先run下这个Java Application工程，右键项目选择export->java->Runnable jar file->导出到D盘中，然后在D:盘根目录下生成文件channelList文件，添加渠道列表内容。
youku
yxfw
jdy
jbjl
sy
zfwl
nmzs
xxfz
hnyx
mmy
wy
azyxlt
ayx
bsj
jy
vip_tg
将自己原apk文件放置于如上channelList文件相同目录。我这里放到D盘。CMD窗口运行D:\>java -jar apkTool.jar RedFingerClient.apk all 2.1.15就能打出所有渠道包。生成一个渠道就需将all 修改成渠道名称即可。
D:>java -jar apkTool.jar RedFingerClient.apk all 2.1.15
接收第一个参数源apk：RedFingerClient.apk
源apk所在路径:
源apk名称:RedFingerClient.apk
接收到的渠道名称:all
接收到的渠道版本:2.1.15
开始生成所有渠道包...
无需生成红手指渠道apk...
生成渠道包成功，渠道：hsz_uat...
生成渠道包成功，渠道：youku...
生成渠道包成功，渠道：yxfw...

生成渠道包成功，渠道：ayx...
生成渠道包成功，渠道：bsj...

生成渠道包成功，渠道：vip_tg...
生成渠道包完毕...
现在就可以在新生产的渠道apk中查看重要的渠道文件了。
我这里把apk文件格式改成.zip格式方便查看。
我们看看内容channel文件内容：
现在接下来就需通过apk文件去获取渠道名称和渠道ID了，详细代码如下：
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;
import org.json.JSONException;
import org.json.JSONObject;
import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.util.Log;
public class ChannelUtil {
private String channelName = null;
private String channelId = null;
private String channelVersion = null;
private Context context;
private static ChannelUtil channelUtil;
/**
* 获取渠道名称
* @return
*/
public String getChannelName() {
return channelName;
}
/**
* 获取渠道ID
* @return
*/
public String getChannelId() {
return channelId;
}
/**
* 获取渠道版本
* @return
*/
public String getChannelVersion() {
return channelVersion;
}
public static ChannelUtil getInstant(Context context) {
if (channelUtil==null) {
channelUtil = new ChannelUtil(context);
}
return channelUtil;
}
private ChannelUtil(Context context) {
this.context = context;
}
public ChannelUtil init() {
final String start_flag = "channel";
ApplicationInfo appinfo = context.getApplicationInfo();
String sourceDir = appinfo.sourceDir;
ZipFile zipfile = null;
try {
zipfile = new ZipFile(sourceDir);
Enumeration<?> entries = zipfile.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = ((ZipEntry) entries.nextElement());
String entryName = entry.getName();
if (entryName.contains(start_flag)&&!entry.isDirectory()) {
InputStream inputStream = null;
try {
inputStream = new BufferedInputStream(zipfile.getInputStream(entry));
} catch (IOException e) {
e.printStackTrace();
Log.e("ChannelUtil", "Read channel failure");
}
if (inputStream!=null) {
String jsonStr = getInputStreamTxt(inputStream);
JSONObject jsonObject = new JSONObject(jsonStr);
channelName = jsonObject.getString("channelName");
channelId = jsonObject.getString("channelID");
channelVersion = jsonObject.getString("channelVersion");
}
break;
}
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
} finally {
if (zipfile != null) {
try {
zipfile.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
if (channelName==null||channelId==null||channelVersion==null) {
channelName = "com.redfinger.app";
channelId = "com.redfinger.app";
channelVersion = "3.1.14";
}
return this;
}
/**
* 读取传入输入流的内容
* @param iStream
* @return 内容
* @throws IOException 会跑出IO异常
*/
public String getInputStreamTxt(InputStream iStream) throws IOException{
StringBuffer out = new StringBuffer();
byte[] b = new byte[1024];
int n;
while ((n = iStream.read(b)) != -1) {
out.append(new String(b, 0, n));
}
return out.toString();
}
}
//获取渠道名称和渠道ID
ChannelUtil util = ChannelUtil.getInstant(this);
TextView tv = (TextView) findViewById(R.id.channel);
tv.setText("渠道名:"+util.getChannelName()+"\n"+"渠道ID："+util.getChannelID());
至此，多渠道打包完毕，万圣节不快乐....
