当我检查互联网连接并且没有互联网时,我的启动活动出错了.它可能发生在我的警报对话框中.

java.lang.RuntimeException:

package com.example.study;

import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;

import com.example.study.helper.SessionManager;
import com.example.study.util.ConnectionDetector;

public class Splash extends AppCompatActivity {

    private ConnectionDetector cd;
    Boolean isInternetPresent = false;
    protected SessionManager session;

    private AlertDialog.Builder builder;


    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);


        builder = new AlertDialog.Builder(Splash.this);
