Android多渠道打包没你想的那么复杂

in android •  7 years ago  (edited)

上一篇《Android多渠道打包没你想的那么复杂》中说了用gradle方法进行多渠道打包,这个方法简单也好理解,但是速度不敢恭维。今天跟大家说说用Python的方法来打包,那感觉...

1.添加渠道

info目录下的channel.txt中添加要上传的渠道名。一定以回车分隔,就是每个名字占一行。

2.Python脚本

其实方法来自于美团。就是将apk解压,在META-INF目录下添加一个以渠道名channel_渠道名为前缀的空文件。如图:


创建一个名为empty.txt的空文件

# 空文件 便于写入此空文件到apk包中作为channel文件
src_empty_file = 'info/empty.txt'
# 创建一个空文件(不存在则创建)
f = open(src_empty_file, 'w')
f.close()

获取目录下所有的apk(所以,可以同时多个apk打包哦~)

src_apks = []
# python3 : os.listdir()即可,这里使用兼容Python2的os.listdir('.')
for file in os.listdir('.'):
    if os.path.isfile(file):
        extension = os.path.splitext(file)[1][1:]
        if extension in 'apk':
            src_apks.append(file)

获取渠道列表

channel_file = 'info/channel.txt'
f = open(channel_file)
lines = f.readlines()
f.close()

解压,读写等操作

for src_apk in src_apks:
    # file name (with extension)
    src_apk_file_name = os.path.basename(src_apk)
    # 分割文件名与后缀
    temp_list = os.path.splitext(src_apk_file_name)
    # name without extension
    src_apk_name = temp_list[0]
    # 后缀名,包含.   例如: ".apk "
    src_apk_extension = temp_list[1]

    # 创建生成目录,与文件名相关
    output_dir = 'output_' + src_apk_name + '/'
    # 目录不存在则创建
    if not os.path.exists(output_dir):
        os.mkdir(output_dir)

    # 创建临时目录,与文件名相关
    temp_dir = 'temp' + src_apk_name + '/'
    # 目录不存在则创建
    if not os.path.exists(temp_dir):
        os.mkdir(temp_dir)


    out_temp_apk = temp_dir + src_apk_name+'temp'+src_apk_extension;
    #copy一份没有渠道信息的apk
    zin = zipfile.ZipFile (src_apk, 'a', zipfile.ZIP_DEFLATED)
    zout = zipfile.ZipFile (out_temp_apk, 'w')
    for item in zin.infolist():
        buffer = zin.read(item.filename)
        if (item.filename[0:16:] != 'META-INF/channel'):
            zout.writestr(item, buffer)
    zout.close()
    zin.close()


    # 遍历渠道号并创建对应渠道号的apk文件
    for line in lines:
        # 获取当前渠道号,因为从渠道文件中获得带有\n,所有strip一下
        target_channel = line.strip()
        # 拼接对应渠道号的apk
        target_apk = output_dir + src_apk_name + "_" + target_channel + src_apk_extension
        # 拷贝建立新apk
        shutil.copy(out_temp_apk, target_apk)
        # zip获取新建立的apk文件
        zipped = zipfile.ZipFile(target_apk, 'a', zipfile.ZIP_DEFLATED)
        # 初始化渠道信息
        empty_channel_file = "META-INF/channel_{channel}".format(channel=target_channel)


        for item in zipped.infolist():
            if (item.filename[0:16:] == 'META-INF/channel'):
                print (item.filename)
        # 写入渠道信息

        zipped.write(src_empty_file, empty_channel_file)
        # 关闭zip流
        zipped.close()

3.第三方统计平台设置对应渠道名

美团有说过友盟的设置方法,由于我用的是腾讯分析,我在这里就说下腾讯的,在MainActivityonCreate方法里添加:

 StatConfig.setInstallChannel(ChannelUtils.getChannel(this));

ChannelUtils.java文件:

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.pm.ApplicationInfo;
import android.util.Log;

import java.io.IOException;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

/**
 * 渠道工具类
 * Created by shd on 2016/6/28.
 */
public class ChannelUtils {
    public static final String Version = "version";

    public static final String Channel = "channel";

    public static final String DEFAULT_CHANNEL = "yunxiao";

    public static final String Channel_File = "channel";

    public static String getChannelFromMeta(Context context) {
        ApplicationInfo appinfo = context.getApplicationInfo();
        String sourceDir = appinfo.sourceDir;
        String ret = "";
        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.startsWith("META-INF") && entryName.contains("channel_")) {
                    ret = entryName;
                    break;
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (zipfile != null) {
                try {
                    zipfile.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        String[] split = ret.split("_");
        if (split != null && split.length >= 2) {
            return ret.substring(split[0].length() + 1);
        } else {
            return DEFAULT_CHANNEL;
        }
    }

    /**
     * 得到渠道名
     *
     * @param mContext
     * @return
     */
    public static String getChannel(Context mContext) {
        String channel = "";
        if (isNewVersion(mContext)) {//是新版本
            Log.e("isNewVersion  %s", "isNewVersion");
            saveChannel(mContext);//保存当前版本
            channel = getChannelFromMeta(mContext);
        } else {
            channel = getCachChannel(mContext);
        }
        return channel;
    }

    /**
     * 保存当前的版本号和渠道名
     *
     * @param mContext
     */
    public static void saveChannel(Context mContext) {
        SharedPreferences mSettinsSP = mContext.getSharedPreferences(Channel_File, Activity.MODE_PRIVATE);
        SharedPreferences.Editor mSettinsEd = mSettinsSP.edit();
        mSettinsEd.putString(Version, PhoneInformationUtils.getAppVersionName(mContext));
        mSettinsEd.putString(Channel, getChannelFromMeta(mContext));
        //提交保存
        mSettinsEd.commit();
    }

    private static boolean isNewVersion(Context mContext) {
        SharedPreferences mSettinsSP = mContext.getSharedPreferences(Channel_File, Activity.MODE_PRIVATE);
        String version = PhoneInformationUtils.getAppVersionName(mContext);
        Log.e("version%s", version);
        return !mSettinsSP.getString(Version, "").equals(version);
    }

    private static String getCachChannel(Context mContext) {
        SharedPreferences mSettinsSP = mContext.getSharedPreferences(Channel_File, Activity.MODE_PRIVATE);
        return mSettinsSP.getString(Channel, DEFAULT_CHANNEL);
    }
}
