android - android - Admob 广告不使用电话卡（2G 或 3G）显示，但 admob 显示带有 WIFI 的广告

Question

我正在尝试在 2g 或 3g 上使用 admob 展示广告。WIFI效果很好。有了WIFI，我看到了很多广告。但是当我换成电话卡时，我什么也看不到。有人知道为什么吗？

编辑：

乌普斯。我有它。

ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
if (mWifi.isConnected()) {
    // Show Ads
}

我正在检查第一个 WIFI，然后显示广告。这是什么逻辑。WIFI删除其工作后。

嗨使用这样的条件

ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

//mobile
State mobile = conMan.getNetworkInfo(0).getState();

//wifi
State wifi = conMan.getNetworkInfo(1).getState();

and then use it like that:

if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State.CONNECTING) {
    //mobile // so call the ads method
} else if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING) {
    //wifi // so call the ads method. 
}

否则也使用下面的代码

ConnectivityManager manager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);

//For 3G check
boolean is3g = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE)
            .isConnectedOrConnecting();
//For WiFi Check
boolean isWifi = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI)
            .isConnectedOrConnecting();

System.out.println(is3g + " net " + isWifi);

if (!is3g && !isWifi) 
{ 
Toast.makeText(getApplicationContext(),"Please make sure your Network Connection is ON ",Toast.LENGTH_LONG).show();
} 
 else 
{ 
        " Your method what you want to do "
}
