推荐答案

下面是code段。它返回true，如果网络允许，否则为假

Here is code snippet. It returns true if network enable ,else false

private boolean netCheckin() {
    try {
        ConnectivityManager nInfo = (ConnectivityManager) getSystemService(
            Context.CONNECTIVITY_SERVICE);
        nInfo.getActiveNetworkInfo().isConnectedOrConnecting();
        Log.d(tag, "Net avail:"
            + nInfo.getActiveNetworkInfo().isConnectedOrConnecting());
        ConnectivityManager cm = (ConnectivityManager) getSystemService(
            Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = cm.getActiveNetworkInfo();
        if (netInfo != null && netInfo.isConnectedOrConnecting()) {
            Log.d(tag, "Network available:true");
            return true;
        } else {
            Log.d(tag, "Network available:false");
            return false;
        }
    } catch (Exception e) {
        return false;
    }
}
