Using a progress Bar while I load a webpage in android

Using a progress Bar while I load a webpage in android - android

I'm currently loading a webpage using a thread and I need a progress bar to display while the page loads up. Whats the best way to implement this? My code to load the webpage is this
private Thread checkUpdate = new Thread() {
#Override
public void run() {
try {
/**
* establish a URL connection
*/
URL updateURL = new URL("http://www.mtsu.edu/alertupdates/");
URLConnection conn = updateURL.openConnection();
/**
* create an Input stream and buffered array to
* prepare for parsing.
*/
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
/**
* read in the html and parse it to bytes.
*/
int current = 0;
while((current = bis.read()) != -1){
baf.append((byte)current);
}
/**
* Convert the Bytes read to a String.
*/
html = new String(baf.toByteArray());
int position = html.indexOf("<h1>");
int position2 = html.indexOf("<!--",position);
html = html.substring(position, position2);
mHandler.post(showUpdate);
} catch (Exception e){}
}
};

in both method i got the following error
com.amazonaws.services.s3.model.AmazonS3Exception: Forbidden (Service: Amazon S3; Status Code: 403; Error Code: 403 Forbidden; Request...
Here i must pass customer header parameters, so i add like following
ObjectMetadata objectMetadata = new ObjectMetadata();
HashMap<String, String> mMetaMap = new HashMap<String, String>();
mMetaMap.put("content-type", "image/jpeg");
mMetaMap.put(Constants.APP_HEADER_REFERER, Constants.APP_REFERER_URL);
objectMetadata.setUserMetadata(mMetaMap);
But still i got the above error.
Is i'm passing the header parameters in correct way either i need to do changes. Kindly advise on this. Thanks

please any help will be appropriated,

Most likely it's a problem with the path to the directory holding your pictures. Please compare the value returned by Environment.getExternalStorageDirectory() method on your phone with the one returned on the emulator. They may be different, thus you may need to move your images accordingly.

This is done in the onCreate method of the activity, but when the activity runs and the button is touched, the event is never triggered and I can't see where I am going wrong. Not sure if its a case of not being able to see the wood for the trees.

I have copied your class, commenting the part of code i don't have relation (owner classes, own files...).
I made a test main.xml and everything works. Have you tried a "Project/Clean", maybe the ID from your btnSpeak is not updated
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

Android: ProgressBar for HttpURLConnection String data

I am getting JSON data from a web service and would like to display a progress bar while the data is downloading. All the examples I have seen use a StringBuilder like so:
//Set up the initial connection
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
connection.setDoOutput(true);
connection.setReadTimeout(10000);
connection.connect();
InputStream stream = connection.getInputStream();
//read the result from the server
reader = new BufferedReader(new InputStreamReader(stream));
StringBuilder builder = new StringBuilder();
String line = "";
while ((line = reader.readLine()) != null) {
builder.append(line + '\n');
}
result = builder.toString();
I got the ProgressBar to work by downloading the data as a byte array, then converting the byte array to a String, but I'm wondering if there is a 'more correct' way to do this. Since I've found no other way of doing this, the following class can also serve as a working example, seems a bit of a hack, but it does work well.

UPDATE: Here is the finished version of the class using the suggestions from Nikolay. I ended up using the StringBuilder after all. The previous version would break because some times connection.getContentLength() returns -1. This version degrades gracefully for that case. Tested this implementation quite a bit and it seems bulletproof.

Well, since content length is reported in bytes, there is really no other way. If you want to use a StringReader you could take the length of each line you read and calculate the total bytes read to achieve the same thing. Also, the regular idiom is to check the return value of read() to check if you have reached the end of the stream. If, for some reason, the content length is wrong, your code may read more/less data then available. Finally, when converting a byte blob to a string, you should explicitly specify the encoding. When dealing with HTTP, you can get that from the 'charset' parameter of the 'Content-Type' header.

I had similar problem. I tried the solution of Jeremy C, but it was inaccurate, because value of "Content-Length" from header can be very different than real data.
My solution is:
Send HTTP header from server (PHP):
$string = json_encode($data, JSON_PRETTY_PRINT | JSON_FORCE_OBJECT);
header("X-Size: ".strlen($string)); //for example with name: "X-Size"
print($string);
Read correct value "X-size" for contentLength variable from HTTP header before read from stream:
protected String doInBackground(URL... urls) {
if (General.DEBUG) Log.i(TAG, "WebAsyncTask(doInBackground)");
String result = "";
BufferedReader reader = null;
try {
HttpURLConnection conn = (HttpURLConnection) urls[0].openConnection();
conn.setConnectTimeout(General.TIMEOUT_CONNECTION);
conn.setReadTimeout(General.TIMEOUT_SOCKET);
conn.setRequestMethod("GET");
conn.connect();
if (General.DEBUG) Log.i(TAG, "X-Size: "+conn.getHeaderField("X-Size"));
if (General.DEBUG) Log.i(TAG, "getHeaderField: "+conn.getHeaderFields());
if(conn.getResponseCode() != General.HTTP_STATUS_200)
return General.ERR_HTTP;
int contentLength = -1;
try {
contentLength = Integer.parseInt(conn.getHeaderField("X-Size"));
} catch (Exception e){
e.printStackTrace();
}
InputStream stream = conn.getInputStream();
reader = new BufferedReader(new InputStreamReader(stream));
StringBuilder builder = new StringBuilder();
//Pokud delku zname:
if(contentLength > -1){
byte[] data = new byte[16]; //TODO
int totalRead = 0;
int bytesRead = 0;
while ((bytesRead = stream.read(data)) > 0){
Thread.sleep(100); //DEBUG TODO
try {
builder.append(new String(data, 0, bytesRead, "UTF-8"));
} catch (UnsupportedEncodingException e) {
Log.i(TAG, "Invalid charset: " + e.getMessage());
//Append without charset (uses system's default charset)
builder.append(new String(data, 0, bytesRead));
}
totalRead += bytesRead;
int progress = (int) (totalRead * (100/(double) contentLength));
Log.i(TAG, "length = " + contentLength + " bytesRead = " + bytesRead + " totalRead = " + totalRead + " progress = " + progress);
publishProgress(progress);
}
} else {
String line = "";
while ((line = reader.readLine()) != null) {
