[Permissions] Read a website to an TextView

[NelsonPRSousa]

Hi guys,

I am new here; First of all I wish you all the best and hope I can learn something with you!

I am with a problem: I can not read html from a website with my Android app. I think the problem is because of Internet permissions.

HttpExample (who is launched)

package com.example.httpexample;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;

public class HttpExample extends Activity {

	TextView httpStuff;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_http_example);
		
		httpStuff = (TextView) findViewById(R.id.tvHttp);
		GetMethodEx test = new GetMethodEx();
		String returned;
		httpStuff.setText("Debugging 1 - onCreate");
		try {
			returned = test.getInternetData();
			httpStuff.setText(returned);
		} catch (Exception e) {
			httpStuff.setText("Debbuging 3 - catch");
			e.printStackTrace();
		}
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.http_example, menu);
		return true;
	}

}

Right here I tried to debugging and my textview get the exception from catch.

GetMethodEx

package com.example.httpexample;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URI;

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

public class GetMethodEx {
	
	public String getInternetData() throws Exception{
		BufferedReader in = null;
		String data = null;
		try{
			HttpClient client = new DefaultHttpClient();
			URI website = new URI("http://www.mybringback.com/");
			HttpGet request = new HttpGet();
			request.setURI(website);
			HttpResponse response = client.execute(request);
			in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
			StringBuffer sb = new StringBuffer("");
			String l = "";
			String nl = System.getProperty("line.separator");
			while((l = in.readLine()) != null){
				sb.append(l + nl);
			}
			in.close();
			data = sb.toString();
			return data;
		}finally{
			if(in != null){
				try{
					in.close();
					return data;
				} catch(Exception e) {
					e.printStackTrace();
				}
			}
		}
	}
	
}
