Question

我尝试使用此video

安装jsoup

然后，出现了一堆问题，一个接一个：

解决了所有问题后，我尝试运行我的测试应用程序（这是我的MainActivity）

package babis.querytest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.i("qt","before");
    try {
        Log.i("qt","before1");
        Document doc= Jsoup.connect("http://www.google.com").get();
        Log.i("qt","after0");
    } catch (IOException e) {

    }
    Log.i("qt","after");
}
}

我的Logcat就是这个

我的build.gradle就是这个

应用程序在文档行崩溃。问题是什么？（wifi工作正常）

你必须在不在主线程上的异步任务中运行它

 new AsyncTask<Void, Void, Document>() {
            @Override
            protected Document doInBackground(Void... params) {
                Document doc= Jsoup.connect("http://www.google.com").get();
                return doc;
            }

            @Override
            protected void onPostExecute(Document document) {
                //parse docement here
            }
        }.execute((Void) null);

无法在Android Studio
