Android 获取渠道名称

直接看代码，

 

//获取渠道名称
public static String getChannelName(Activity ctx) {
    if (ctx == null) {
        return null;
    }
    String channelName = "";
    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("TD_CHANNEL_ID");
                }
            }

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