    outputDir = file('out')
    channels = ["qihu360","baidu","yingyongbao","wandoujia","taobao","xiaomi","nearme","anzhuo","anzhi","meizu"]
}

3.Use gradle mulchannel to make multiple channel apks

In Local(Need clone this project to use)

1.Use gradle install command,To install the plug in local maven

2.Add dependency to the top-level build.gradle file.

  buildscript {
    repositories {

5.Use gradle mulchannel to make multiple channel apks

Get channel

  public static String getChannel(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/mulchannel")) {
                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);
