    public static String getChannelName(Activity ctx) {
        if (ctx == null) {
            return null;
        }
        String channelName = null;
        try {
            PackageManager packageManager = ctx.getPackageManager();
            if (packageManager != null) {
                //注意此处为ApplicationInfo 而不是 ActivityInfo,因为友盟设置的meta-data是在application标签中，而不是某activity标签中，所以用ApplicationInfo
                ApplicationInfo applicationInfo = packageManager.getApplicationInfo(ctx.getPackageName(), PackageManager.GET_META_DATA);
                if (applicationInfo != null) {
                    if (applicationInfo.metaData != null) {
                        channelName = applicationInfo.metaData.getString("");
                    }
                }

            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return channelName;
    }

提取为通用方法：

    public static String getAppMetaData(Context ctx, String key) {
        if (ctx == null || TextUtils.isEmpty(key)) {
            return null;
        }
        String resultData = null;
        try {
            PackageManager packageManager = ctx.getPackageManager();
            if (packageManager != null) {
                ApplicationInfo applicationInfo = packageManager.getApplicationInfo(ctx.getPackageName(), PackageManager.GET_META_DATA);
                if (applicationInfo != null) {
                    if (applicationInfo.metaData != null) {
                        resultData = applicationInfo.metaData.getString(key);
                    }
                }

            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }

        return resultData;
    }

public static string getchannelname(activity ctx) { if (ctx == null) { return null; } string channelname = null; try { packagemanager packagemanager = ctx.getpackagemanager(); if (packagemanager != null) { //注意此处为applicationinfo 而不是 activityinfo,因为友盟设置的meta-data是在application标签中，而不是某activity标签中，所以用applicationinfo applicationinfo applicationinfo = packagemanager.getapplicationinfo(ctx.getpackagename(), packagemanager.get_meta_data); if (applicationinfo != null) { if (applicationinfo.metadata != null) { channelname = applicationinfo.metadata.getstring(""); } } } } catch (packagemanager.namenotfoundexception e) { e.printstacktrace(); } return channelname; } 抽取之后： public static string getappmetadata(context ctx, string key) { if (ctx == null || textutils.isempty(key)) { return null; } string resultdata = null; try { packagemanager packagemanager = ctx.getpackagemanager(); if (packagemanager != null) { applicationinfo applicationinfo = packagemanager.getapplicationinfo(ctx.getpackagename(), packagemanager.get_meta_data); if (applicationinfo != null) { if (applicationinfo.metadata != null) { resultdata = applicationinfo.metadata.getstring(key); } } } } catch (packagemanager.namenotfoundexception e) { e.printstacktrace(); } return resultdata; }
