The Right Data isn't displaying for my App- Android
Question
I am scraping data from a local HTML page in Android Studio and instead of the right info being displayed all that its displaying is a blank screen. Anyone know how to display the data i have scraped? Below is a the main piece of code.
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
StringBuilder buf=new StringBuilder();
InputStreamReader inputStream = new InputStreamReader(getAssets().open("filename.html"));
BufferedReader bufferedReader = new BufferedReader(inputStream);
String str;
while ((str=bufferedReader.readLine()) != null) {
buf.append(str);
}
Document doc = Jsoup.parse(buf.toString());
StringBuilder sb = new StringBuilder();
Elements tableElements = doc.select("td[colspan='1']");
TextView textView = (TextView)findViewById(R.id.text_view);
for (Element td : tableElements) {
sb.append(td.text() + "\n");
System.out.println(td.text());
}
textView.setText(sb.toString());
} catch (IOException e) {
e.printStackTrace();
}
}
} HTML

Do this, this is based on your previous question :
Document doc = Jsoup.parse(buf.toString());
StringBuilder sb = new StringBuilder();
Elements tableElements = doc.select("td[colspan='1']");
TextView textView = (TextView)findViewById(R.id.text_view);
for (Element td : tableElements) {
sb.append(td.text() + "\n");
System.out.println(td.text());
}
textView.setText(sb.toString());
