android.app中不推荐使用ProgressDialog

Question

在过去的几天里，我一直收到以下错误：“不赞成使用android.app中的[deprecation] ProgressDialog”和“不赞成使用android.net中的[deprecation] NetworkInfo”。我不确定是否来自模拟器还是从代码？

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;



public class UtilTCM {
  public static boolean verifyConnection(Context context) {
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = cm.getActiveNetworkInfo();
    if (networkInfo != null && networkInfo.isConnected()) {
      return true;
    } else {
      return false;
    }
  }
}

此清单

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
