I'm trying to read a line of text from a URL and display the result in a Textview.
ISSUE/ERROR:
At present there is no error, the textview is not populated after I execute DownloadWebPage Async task.
INVESTIGATIONS
I believe I may not be calling this correctly, as I can't find any results from my debug calls, in DownloadWebPage. Also my URL has one line of code with two strings, if that makes any difference.
UPDATE:
In DownloadWebPage my logs commands are not showing in the log files - weird
CODE: ON CREATE:
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.inbox_list);
textView = (TextView) findViewById(R.id.textView6);
// Hashmap for ListView
inboxList = new ArrayList<HashMap<String, String>>();
//ASYNC TASK I CREATED
new DownloadWebPageTask().execute();
// Another Async Task in my code
new LoadInbox().execute();
}
CODE: AsyncTask for Parsing Data from URL & Setting Data to Textview
private class DownloadWebPageTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(
new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
System.out.println(response);
} catch (Exception e) {
e.printStackTrace();
}
}
return response;
}
#Override
protected void onPostExecute(String result) {
textView.setText(Html.fromHtml(result));
}
}
public void readWebpage(View view) {
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] { "http://www.url.com/blah.php" });
}
I am calling this method from JavaScript.
For the first time, it is giving null. But from the second time onwards, the data is coming.
Please help me.
#SuppressLint("JavascriptInterface")
public String loadClickedData() {
pDialog = ProgressDialog.show(this, "dialog title",
"dialog message", true);
new HttpAsyncTaskClickedData()
.execute("http://192.168.0.9/btrepo/btrepo/android_api.php");
return bdb.getmPosIdData();
}
Here we are getting data through AsyncTask in Android:
private class HttpAsyncTaskClickedData extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("tag", "get_pos_details"));
nameValuePairs.add(new BasicNameValuePair("pos_id", posId));
return GET(urls[0], nameValuePairs);
}
// onPostExecute displays the results of the AsyncTask.
#Override
protected void onPostExecute(String result) {
// Toast.makeText(getApplicationContext(), result+" in post ",
// Toast.LENGTH_LONG).show();
pDialog.dismiss();
Toast.makeText(getApplicationContext(), result, Toast.LENGTH_LONG)
.show();
bdb.setmPosIdData(result);
}
}
This method is for getting data from the server:
public static String GET(String url, List<NameValuePair> pair) {
InputStream inputStream = null;
String result = "";
try {
// create HttpClient
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(pair));
HttpResponse httpResponse = httpClient.execute(httpPost);
// receive response as inputStream
inputStream = httpResponse.getEntity().getContent();
is = inputStream;
// convert inputstream to string
if (inputStream != null) {
// jObj = convertIsToJson(inputStream);
result = convertIsToJson(inputStream) + " ";
// jSonStr = result;
} else
result = "Did not work!";
} catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
return result;
}
I am getting data from the server in json string format.
It is displaying attributes with null value like {pos["posid":null, "storeName":null]} etc..
In the following function
public String loadClickedData() {
pDialog = ProgressDialog.show(this, "dialog title",
"dialog message", true);
new HttpAsyncTaskClickedData()
.execute("http://192.168.0.9/btrepo/btrepo/android_api.php");
return bdb.getmPosIdData();
}
You execute your HttpAsyncTaskClickedData(), and return bdb.getmPosIdData() immediately. (Which will always be an issue for the 1st time)
The result of the AsyncTask is only available in onPostExecute, where you call bdb.setmPosIdData(result);.
#Override
protected void onPostExecute(String result) {
// ...
bdb.setmPosIdData(result); // result is only stored in bdb here!
}
The HttpAsyncTaskClickedData runs in the background, and possibly takes some time.
That is why your first call is always unable to get data, as you returned bdb.getmPosIdData() immediately after executing your AsyncTask.
private class HttpAsyncTaskClickedData extends
AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs
.add(new BasicNameValuePair("tag", "get_pos_details"));
nameValuePairs.add(new BasicNameValuePair("pos_id", posId));
return GET(urls[0], nameValuePairs);
}
// onPostExecute displays the results of the AsyncTask.
#Override
protected void onPostExecute(String result) {
// Toast.makeText(getApplicationContext(), result+" in post ",
// Toast.LENGTH_LONG).show();
data = result;
pDialog.dismiss();
bdb.setmPosIdData(result);
}
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = ProgressDialog.show(MainActivity.this, "dialog title",
"dialog message", true);
}
#SuppressLint("JavascriptInterface")
public String loadData() {
Toast.makeText(getApplicationContext(), data+ " hi ",
Toast.LENGTH_LONG).show();
return data;
}
}
and calling loadData() method from javascript.
This function is for get data by using post url in javascript
function jsonPost(){
var http = new XMLHttpRequest();
var url = "http://192.168.0.9/btrepo/btrepo/android_api.php";
var params = "tag=fav_stores&mobile=984989874";
http.open("POST", url, true);
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
alert("hello "+http.send(params));

I have a Webpage loading into my WebView. This webpage loads a login page for the website. As the user enters his credentials he gets redirected to a certain page. I want to stop the loading of the webpage after user enters his credentials and get redirected to another activity instead of the default redirected page.
My idea of doing this is to catch the redirected url and compare it with the url created by me, if both match it should stop loading the default webpage and load another activity. However, Iam able to catch the redirected Urls and show them in a AlertDialog, but cannot stop the loading of the default web page.
Can anyone help me on this?
This is what I have tried:-
myWebView.loadUrl(url);
myWebView.setWebViewClient(new WebViewClient()
{
#Override
public void onPageFinished(WebView view, String url)
{
// TODO Auto-generated method stub
super.onPageFinished(view, url);
if(progressBar.isShowing())
{
progressBar.dismiss();
}
String absoluteUrl = view.getUrl();
absoluteUrl = Uri.decode(absoluteUrl);
//int absoulteCount = absoluteUrl.length();
String redirectedUrl = endpointHost+"Authorize/index"+myId;
//int redirectedCount = redirectedUrl.length();
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Details.this);
alertDialogBuilder.setNegativeButton("Ok", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog,int id)
{
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.setMessage(absoluteUrl);
alert.show();
if(absoluteUrl!=null && absoluteUrl.contains(redirectedUrl))
{
view.stopLoading();
Intent myIntent = new Intent(Details.this, Home.class);
startActivity(myIntent);
}
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// TODO Auto-generated method stub
view.loadUrl(url);
HttpClient httpClient = new DefaultHttpClient();
URL myUrl;
URLConnection connection;
try
{
myUrl = new URL(url);
connection = myUrl.openConnection();
connection.setConnectTimeout(3000);
connection.connect();
int size = connection.getContentLength();
}
catch (Exception e) {}
String htmlContent = "";
HttpPost httpGet = new HttpPost(url);
HttpResponse response;
HttpContext httpContext = new BasicHttpContext();
try
{
response = httpClient.execute(httpGet);
if(response.getStatusLine().getStatusCode() == 200)
{
HttpEntity entity = response.getEntity();
if (entity != null)
{
InputStream inputStream = entity.getContent();
htmlContent = convertToString(inputStream);
}
}
}
catch (Exception e) {}
return true;
}
EDIT:- Suggested by #SimplePlan
myWebView.setWebViewClient(new WebViewClient()
{
#Override
public void onPageFinished(WebView view, String url)
{
// TODO Auto-generated method stub
super.onPageFinished(view, url);
if(progressBar.isShowing())
{
progressBar.dismiss();
}
}
private void showAlert2(String Url)
{
// TODO Auto-generated method stub
Url = Uri.decode(Url);
//int absoulteCount = absoluteUrl.length();
String redirectedUrl = endpointHost+"/AuthorizeDevice/index"+deviceId;
//int redirectedCount = redirectedUrl.length();
if(Url!=null && Url.contains("redirect_uri"+redirectedUrl+"?{StandardTokens}"))
{
myWebView.stopLoading();
Intent myIntent = new Intent(Details.this, Home.class);
startActivity(myIntent);
}else{
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Details.this);
alertDialogBuilder.setNegativeButton("Ok", new DialogInterface.OnClickListener()

public void onClick(DialogInterface dialog,int id)
{
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.setMessage(Url);
alert.show();
}
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// TODO Auto-generated method stub
view.loadUrl(url);
showAlert2(url);
return true;
}
Try to implement like:
myWebView.setWebViewClient(new WebViewClient()
{
#Override
public void onPageFinished(WebView view, String url)
{
// TODO Auto-generated method stub
super.onPageFinished(view, url);
if(progressBar.isShowing())
{
progressBar.dismiss();
}
showAlert2(url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// TODO Auto-generated method stub
view.loadUrl(url);
HttpClient httpClient = new DefaultHttpClient();
URL myUrl;
URLConnection connection;
try
{
myUrl = new URL(url);
connection = myUrl.openConnection();
connection.setConnectTimeout(3000);
connection.connect();
int size = connection.getContentLength();
}
catch (Exception e) {}
String htmlContent = "";
HttpPost httpGet = new HttpPost(url);
HttpResponse response;
HttpContext httpContext = new BasicHttpContext();
try
{
response = httpClient.execute(httpGet);
if(response.getStatusLine().getStatusCode() == 200)
{
HttpEntity entity = response.getEntity();
if (entity != null)
{
InputStream inputStream = entity.getContent();
htmlContent = convertToString(inputStream);
}
}
}
catch (Exception e) {}
return true;
}
And showAlert2(url) method:
public void showAlert2(String Url) {
//String absoluteUrl = view.getUrl();
Url = Uri.decode(Url);
//int absoulteCount = absoluteUrl.length();
String redirectedUrl = endpointHost+"Authorize/index"+myId;
//int redirectedCount = redirectedUrl.length();
if(Url!=null && Url.contains(redirectedUrl))
{
myWebView.stopLoading();
Intent myIntent = new Intent(Details.this, Home.class);
startActivity(myIntent);
}else{
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Details.this);
alertDialogBuilder.setNegativeButton("Ok", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog,int id)
{
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.setMessage(Url);
alert.show();
}
}
Try as per my answer and give me feedback on this
could someone please help me. I'm having difficulty with LoadUrl and javascript.
The code below seems to work sorta ok (killing the app then trying again makes it work) on my old HTC running 2.3 however, my Xperia Z which runs the latest Android gets stuck on "Attempting to get Comments".
The section of code it is sticking on is InjectJavaScript() wherein this fails to LoadUrl (I know this as onPageFinished is never called). The strange thing is statistics part of the code works fine and its identical.
Sorry its pretty messy code...

I see that FetchFromEmpathica is going to be called again when you load the second page, and you set again a new WebViewClient() to the webview, put it on the setup() method so it is going to be called once.
Make sure that your Xperia is 4.1.2, nonetheless look what is mentioned on
Reference: JavascriptInterface methods in WebViews must now be annotated
Beginning in Android 4.2, you will now have to explicitly annotate public methods with #JavascriptInterface in order to make them accessible from hosted JavaScript. Note that this also only takes effect only if you have set your app's minSdkVersion or targetSdkVersion to 17 or higher.
Add it and import android.webkit.JavascriptInterface
So the code will be up-to-date to last versions.
#JavascriptInterface
public void processHTML(final String html)
{
//code
}
I am using 8 - 10 different WebViews in one layout and loading different content in each WebView.
While loading Webview shows different messages like "Loading.." "Processing.." etc.
Is there any way to hide these notifications?
Try to use HttpClient to get the webpage's html code and then use WebView.loadData to load the entire page into WebView.

public String convertStreamToString(InputStream is, String charset) throws IOException {
if (is != null) {
Writer writer = new StringWriter();
char[] buffer = new char[1024];
try {
Reader reader = new BufferedReader(new InputStreamReader(is, charset));
int n;
while ((n = reader.read(buffer)) != -1) {
writer.write(buffer, 0, n);
}
} finally {
is.close();
}
return writer.toString();
} else {
return "";
}
}
protected String doInBackground(Integer... params) {
String r = "";
try {
HttpClient hc = new DefaultHttpClient();
HttpGet get = new HttpGet("http://google.com"); // replace with the url
HttpResponse hr = hc.execute(get);
if(hr.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
InputStream is = hr.getEntity().getContent();
r = convertStreamToString(is, "UTF-8");
} else {
r = "Error";
}
} catch(Exception e){
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String result) {
WebView wv = (WebView) findViewById(R.id.web_view); // replace web_view with the webView id
wv.loadData(result, "text/html", "utf-8");
}
protected void onPreExecute() {
}
}
Then call new exampleHttpTask().exec() to load the webpage.
