Ajuda com Jsoup e AsyncTask

18/08/2017

Bom basicamente eu j� estou com do de cabe�a por causa desta p****, o plano era baixar uma p�gina web para pegar o atributo src (e futuramente outros) para usar como url no video player.

C�digo do Player:

package com.samuelives.videoplayer;

import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.WindowManager;
import android.widget.MediaController;
import android.widget.VideoView;

import com.samuelives.videoplayer.system.PageDownloader;

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

import java.io.IOException;

/**

 */

public class Player extends AppCompatActivity{

    private PageDownloader page;

    @Override
    protected void onCreate(Bundle saveInstanceState){
        super.onCreate(saveInstanceState);
        setContentView(R.layout.activity_player_offline);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        VideoView mVideoView = (VideoView)findViewById(R.id.vVideoPlayerOffline);
        MediaController mc = new MediaController(this);

        Intent it = getIntent();
        String mUrl = it.getStringExtra("URLVideo");
        Log.i("Video Player URL: ", mUrl);

        //Src do video
        String mSrc = mUrl;

        //verifica se � a url de um video
        if(!(mUrl.contains(".mp4") || mUrl.contains(".3gp") || mUrl.contains(".MP4") || mUrl.contains(".3GP"))){
            page = new PageDownloader(mUrl);
            page.execute();
            mSrc = page.getVideoSrc();
            Log.i("SRC do v�deo", mSrc);
        }else {
            mSrc = mUrl;
        }

        //Url do video
        Uri url = Uri.parse(mSrc);

        //Video Player
        mVideoView.setMediaController(mc);
        mVideoView.setVideoURI(url);
        mVideoView.start();

    }



}

C�digo da p�gina de download:

package com.samuelives.videoplayer.system;

import android.os.AsyncTask;

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

import java.io.IOException;

/**
 * Created by sives on 18/08/2017.
 */

public class PageDownloader extends AsyncTask<String, Void, String>{

    private String mUrl, mSrc;
    private Document page;

    public PageDownloader(String url){
        this.mUrl = url;
    }

    public String getVideoSrc(){
        return mSrc;
    }

    @Override
    protected String doInBackground(String... strings) {

        try {
            page = Jsoup.connect(mUrl).get();
            Element video = page.select("video").first();

            //Seta para o src
            mSrc = video.attr("src");

        } catch (IOException e) {
            e.printStackTrace();
        }

        return null;
    }

}

E o c�digo da Activity principal:

package com.samuelives.videoplayer;

import android.content.Intent;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Gravity;
import android.view.View;
import android.widget.EditText;

import com.mikepenz.materialdrawer.Drawer;
import com.mikepenz.materialdrawer.DrawerBuilder;
import com.mikepenz.materialdrawer.model.PrimaryDrawerItem;

public class Main extends AppCompatActivity {

    private Drawer mNavDrawer;

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

        Toolbar tbMain = (Toolbar)findViewById(R.id.tbMain);
        tbMain.setTitle("Video Player+");
        tbMain.setTitleTextColor(Color.parseColor("#F5F5F5"));
        setSupportActionBar(tbMain);

        //Items
        PrimaryDrawerItem itemOffline = new PrimaryDrawerItem().withIdentifier(1).withName("Salvos Offline").withTextColor(Color.parseColor("#263238")).withIcon(R.mipmap.ic_file_download_black_24px);

        //Navigation Drawer
        mNavDrawer = new DrawerBuilder()
        .withActivity(this)
        .withToolbar(tbMain)
        .withDisplayBelowStatusBar(true)
        .withActionBarDrawerToggleAnimated(true)
        .withDrawerGravity(Gravity.LEFT)
        .withSavedInstance(savedInstanceState)
        .withSelectedItem(0)
        .addDrawerItems(
                   itemOffline
         )
        .build();


    }

    public void openPlayer(View v){
        EditText editurl = (EditText)findViewById(R.id.editText);
        Intent player = new Intent(this, Player.class);
        player.putExtra("URLVideo", editurl.getText().toString());
        startActivity(player);
    }

}

Bom basicamente, quando vou executar um v�deo direto pela url dele ele executa normalmente, por�m em alguns dispositivos android (pelo menos no meu J2) n�o da pra copiar a url do player, ent�o fiz um sistema simples para pegar a url do atributo src da tag v�deo para usar no src do player, s� que sempre da este maldito error:
