copied!<p>The problem is that I expect the text that I read from a webpage calling <code>grabURL</code> is absolutely equal to what I put into <code>String lorem</code> in the <code>onPostExecute</code>.</p> <p>But Android says: "No, it does not!" </p> <p>Why do I think Android is not right about equality?</p> <p>1) StackTrace screenshot:</p> <p><img src="https://i.stack.imgur.com/cuGri.jpg" alt="STACKTRACE"></p> <p>2) Screenphoto:</p> <p><img src="https://i.stack.imgur.com/YIGvl.jpg" alt="NOT EQUAL"></p> <p>3) You can find <code>String lorem = "Lorem ipsum dolor sit amet";</code> downward in my class, and look through the source code of the webpage I'm reading text from:</p> <p><img src="https://i.stack.imgur.com/FrIOi.jpg" alt="SOURCE CODE"></p> <p>Source code of my classes:</p> <pre><code>public class MainActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); grabURL("http://www.cyberweb.pp.ua/x/o.html"); } public void grabURL(String url) { new GrabURL().execute(url); } private class GrabURL extends AsyncTask<String, Void, Void> { private final HttpClient Client = new DefaultHttpClient(); private String Content; private String Error = null; protected Void doInBackground(String... urls) { try { HttpGet httpget = new HttpGet(urls[0]); ResponseHandler<String> responseHandler = new BasicResponseHandler(); Content = Client.execute(httpget, responseHandler); } catch (ClientProtocolException e) { Error = e.getMessage(); cancel(true); } catch (IOException e) { Error = e.getMessage(); cancel(true); } return null; } protected void onPostExecute(Void unused) { String lorem = "Lorem ipsum dolor sit amet"; if (Error != null) { Toast.makeText(MainActivity.this, Error, Toast.LENGTH_LONG) .show(); } else { TextView xyu = (TextView) findViewById(R.id.xyu); TextView xyu1 = (TextView) findViewById(R.id.xyu1); TextView xyu2 = (TextView) findViewById(R.id.xyu2); xyu.setText(Content); xyu1.setText(lorem); Log.v("lorem", lorem); Log.v("Content", Content); String eq = null; if (Content.length() != lorem.length()) { Log.v("length?", "Different length"); } if (Content.trim().equalsIgnoreCase(lorem.trim())) { xyu2.setText("EQUAL"); eq = "EQUAL"; Log.v("equal?", eq); } else { xyu2.setText("NOT EQUAL"); eq = "NOT EQUAL"; Log.v("equal?", eq); } } } } } </code></pre> <p>This issue is driving me nuts. </p> <p>Сan anybody guess what happens? Thank you in advance!</p> <p>Last Stacktrace:</p> <p><img src="https://i.stack.imgur.com/fjH3g.jpg" alt="enter image description here"></p> <p><strong>The issue was caused by webpage encoding. Equality is correct when changing the encoding to</strong> <code>UTF-8</code>. </p>
