APK插件打包插件 使用在Android Studio 开发中 gradle 插件，用于产生多个渠道APK工具 900个渠道 一分钟内打包完成，原理是美图的打包方式，只是修改为groovy ，方便gradle 使用 /** * APK 获取渠道号方法 * @param context * @return */ private static String getChannelFromApk(Context context) { long startTime = System.currentTimeMillis(); //从apk包中获取 ApplicationInfo appinfo = context.getApplicationInfo(); String sourceDir = appinfo.sourceDir; //默认放在meta-inf/里， 所以需要再拼接一下 String key = "META-INF/channel"; 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(key)) { ret = entryName; break; } } } catch (IOException e) { e.printStackTrace(); } finally { if (zipfile != null) { try { zipfile.close(); } catch (IOException e) { e.printStackTrace(); } } } String channel = ""; if (!TextUtils.isEmpty(ret)) { String[] split = ret.split("_"); if (split != null && split.length >= 2) { channel = ret.substring(split[0].length() + 1); } } else { channel = "default"; } return channel;
