  • How to add new field(s) to the contact?

    - by user328302
    I want to add a Custom field to the ContactsContract content provider. I'm trying to build a Voip application and would like to add a SIP address(name@domain) field to it. What MIME type will I need to associate with it? Also I want to add a group address field which will have a list of group addresses in it (name@domain, name@domain,...). Wich MIME type will I have to associate with this type of field. I also want to add custom fields to the Call History like a session ID and SIP address(name@domain) field. How can I customize the call history? It'll be great if someone can give me an example.

  • Launch Activity with Intent Filter on Right Time

    - by user511853
    Hi. I want to launch my own media player application when I want to watch a video from Youtube. When I write android:scheme="http" and android:host="m.youtube.com" it is OK. But, it asks everywhere in m.youtube.com to open my app. So, it gets annoying. I tried to use pathPattern, pathPrefix and path to solve this but I didn't get ahead. All I want is clearly this: When the link is like "http://m.youtube.com/index?desktop_uri=%2F%gl=US#" the intent filter shouldn't launch my app. When the link is like "http://m.youtube.com/index?desktop_uri=%2F&gl=US#/watch?xl=xl_blazer&v=k3Cdqx1qFX8" my application should be launched. Is there anyone that can help me?

  • Android - save/restore state of custom class

    - by user1209216
    I have some class for ssh support - it uses jsch internally. I use this class on main activity, this way: public class MainActivity extends Activity { SshSupport ssh = new SshSupport(); ..... @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //Handle events for ssh ssh.eventHandler = new ISshEvents() { @Override public void SshCommandExecuted(SshCommandsEnum commandType, String result) { } //other overrides here } //Ssh operations on gui item click @Override public void onItemClick(AdapterView<?> arg0, View v, int position, long arg3) { if (ssh.IsConnected() == false) { try { ssh.ConnectAsync(/*parameters*/); } catch (Exception e) { e.printStackTrace(); } } try { ssh.ExecuteCommandAsync(SshCommandsEnum.values()[position]); } catch (Exception e) { e.printStackTrace(); } } }); } It works very well. My application connects to ssh, performs all needed operation in background thread and results are reported to gui, via events as shown above. But nothing works after user change device orientation. It's clear for me - activity is re-created and all state is lost. Unfortunately, my SshSupport class object is lost as well. It's pretty easy to store gui state for dynamically changed/added objects (using put/get serializable etc methods). But I have no idea how to prevent my ssh object, ssh connected session being lost. Since my class is not serializable, I can't save it to bundle. Also, even if I make my SshSupport class serializable, jsch objects it uses still are not serializable. So what is the best way to solve this?

  • How do i change Object to String in a class which extends AsyncTask?

    - by Filip V.
    I'm learning from Google's Android developing tutorial and i came across a problem. On this link https://developer.android.com/training/basics/network-ops/connecting.html#AsyncTask it says to create a class that extends AsyncTask. So when i write the class it automatically implements the method as follows: private Object doInBackground(Object... args) {..} //it's fine but when i try writing just as it says in the tutorial: private String doInBackground(String... args) {..} //it gives an error and the error says: The method doInBackground(String...) of type MainActivity.DownloadWebpageText must override a superclass method. So how do i change Object to String without getting an error there?

  • Write to PDF using PHP from android device

    - by Brent Mitchell
    I am trying to write to a pdf file on php server. I have sent variables to the server, create the pdf document, then have my phone download the document to view on device. The variables seem not to write on the php file. I have my code below public void postData() { try { Calculate calc = new Calculate(); HttpClient mClient = new DefaultHttpClient(); StringBuilder sb=new StringBuilder("myurl.com/pdf.php"); HttpPost mpost = new HttpPost(sb.toString()); String value = "1234"; List nameValuepairs = new ArrayList(1); nameValuepairs.add(new BasicNameValuePair("id",value)); mpost.setEntity(new UrlEncodedFormEntity(nameValuepairs)); } catch (UnsupportedEncodingException e) { Log.w(" error ", e.toString()); } catch (Exception e) { Log.w(" error ", e.toString()); } } And my php code to write the variable "value" onto the pdf document: //code to reverse the string if($_POST[] != null) { $reversed = strrev($_POST["value"]); $this->SetFont('Arial','u',50); $this->Text(52,68,$reversed); } I am just trying to write the variable in a random spot, but the variable the if statement is always null and I do not know why. Thanks. Sorry if it is a little sloppy.

  • Android: Calculator on showing 0 immediately after the dot

    - by pearmak
    I am now working on a calculator, and everything works fine except for decimal places. The calculator contains 2 displays actually, one is called fakedisplay for actual operations, and one is called Display, for presenting the desired format, ie adding commas. When pressing 12345.678, Display will follow fakedisplay and present as 12,345.678, but if i press 12345.009, the fakedisplay will work normally as 12345.009, but the Display stuck as 12,345 until 9 is pressed, and at that time it will show 12,345.009 normally. However, it is strange that when the user presses 0, there is no response, and until pressing 9, 009 will then immediately append. I know this arise from the parsing code, but based on this, how could I amend the following code? I really cannot think of any solution... Many thanks for all your advice! one.setOnClickListener(new View.OnClickListener() { if (str.length()<15) {Fakedisplay.append("1");} DecimalFormat myFormatter1 = new DecimalFormat("###,###,###,###.#################"); String str1=Fakedisplay.getText().toString(); String stripped1 = Double.valueOf(str1).toString(); stripped1 = myFormatter1.format(Double.valueOf(stripped1)); if (stripped1.endsWith(".0")) stripped1 = stripped1.substring(0, stripped1.length() - 2); Display.setText(stripped1);

  • Android - Retrieve all data from a SQLite table row

    - by Paul
    I have searched and cannot find an answer to my issue so i hope i am not completely barking up the wrong tree (so to speak). I am new to android and have started to create an app. My app on one screen creates and adds entries to a SQLite database using public class DatabaseHandler extends SQLiteOpenHelper and this all appears to work. I retrieve all the data and populate it into a grid, again this now works. My issue is I am unable to retrieve one complete line from the grid. I populate/display the grid with the following code. I have cut a lot out as the grid is made in stages, header, blank lines etc but the grid does display as I want. The id’s work as when I touch a line it displays its unique id. The onClick is right at the end and when I use getText() instead of getID() all it returns is the data in the labelDate. How do I retrieve all the labels as listed below? TextView labelDATE = new TextView(this); TextView labelCP = new TextView(this); TextView labelBG = new TextView(this); TextView labelQA = new TextView(this); TextView labelCN = new TextView(this); TextView labelKT = new TextView(this); TextView[] tvArray = {labelDATE, labelCP, labelBG, labelQA, labelCN, labelKT}; labelDATE.setText(re.getTime()); labelCP.setText(re.getCP()); labelBG.setText(re.getBG()); labelQA.setText(re.getQA()); labelCN.setText(re.getCN()); labelKT.setText(re.getKT()); for (TextView tv : tvArray) { tv.setTextColor(Color.WHITE); tv.setId(200+count); tr.setOnClickListener(this); tr.addView(tv); } //add this to the table row tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); public void onClick(View v) { if (v instanceof TableRow) { TableRow row = (TableRow) v; TextView child = (TextView) row.getChildAt(0); Toast toast = Toast.makeText(this, String.valueOf(child.getId()), Toast.LENGTH_SHORT); toast.show(); } } I can supply all the code for the grid creation if required. Thanks for any help.

  • IntentService android download and return file to Activity

    - by Andrew G
    I have a fairly tricky situation that I'm trying to determine the best design for. The basics are this: I'm designing a messaging system with a similar interface to email. When a user clicks a message that has an attachment, an activity is spawned that shows the text of that message along with a paper clip signaling that there is an additional attachment. At this point, I begin preloading the attachment so that when the user clicks on it - it loads more quickly. currently, when the user clicks the attachment, it prompts with a loading dialog until the download is complete at which point it loads a separate attachment viewer activity, passing in the bmp byte array. I don't ever want to save attachments to persistent storage. The difficulty I have is in supporting rotation as well as home button presses etc. The download is currently done with a thread and handler setup. Instead of this, I'd like the flow to be the following: User loads message as before, preloading begins of attachment as before (invisible to user). When the user clicks on the attachment link, the attachment viewer activity is spawned right away. If the download was done, the image is displayed. If not, a dialog is shown in THIS activity until it is done and can be displayed. Note that ideally the download never restarts or else I've wasted cycles on the preload. Obviously I need some persistent background process that is able to keep downloading and is able to call back to arbitrarily bonded Activities. It seems like the IntentService almost fits my needs as it does its work in a background thread and has the Service (non UI) lifecycle. However, will it work for my other needs? I notice that common implementations for what I want to do get a Messenger from the caller Activity so that a Message object can be sent back to a Handler in the caller's thread. This is all well and good but what happens in my case when the caller Activity is Stopped or Destroyed and the currently active Activity (the attachment viewer) is showing? Is there some way to dynamically bind a new Activity to a running IntentService so that I can send a Message back to the new Activity? The other question is on the Message object. Can I send arbitrarily large data back in this package? For instance, rather than send back that "The file was downloaded", I need to send back the byte array of the downloaded file itself since I never want to write it to disk (and yes this needs to be the case). Any advice on achieving the behavior I want is greatly appreciated. I've not been working with Android for that long and I often get confused with how to best handle asynchronous processes over the course of the Activity lifecycle especially when it comes to orientation changes and home button presses...

  • HTML format using Java mail in android

    - by TheDevMan
    I am trying to implement an HTML format mail using the Java mail in android. I would like to get results like this: When I look at the html format sent from lookout in my GMAIL. I don't see any link, but just has this format: [image: Lookout_logo] [image: Signal_flare_icon] Your battery level is really low, so we located your device with Signal Flare. I was trying the following: Properties props = System.getProperties(); props.put("mail.smtp.starttls.enable", "true"); // added this line props.put("mail.smtp.host", host); props.put("mail.smtp.user", from); props.put("mail.smtp.password", pass); props.put("mail.smtp.port", "587"); props.put("mail.smtp.auth", "true"); javax.mail.Session session = javax.mail.Session.getDefaultInstance(props, null); MimeMessage message = new MimeMessage(session); message.setFrom(new InternetAddress(from)); InternetAddress[] toAddress = new InternetAddress[to.length]; // To get the array of addresses for( int i=0; i < to.length; i++ ) { // changed from a while loop toAddress[i] = new InternetAddress(to[i]); } message.setRecipients(Message.RecipientType.BCC, toAddress); message.setSubject(sub); //message.setText(body); body = "<!DOCTYPE html><html><body><img src=\"http://en.wikipedia.org/wiki/Krka_National_Park#mediaviewer/File:Krk_waterfalls.jpg\">"; message.setContent(body, "text/html; charset=utf-8"); Transport transport = session.getTransport("smtp"); transport.connect(host, from, pass); transport.sendMessage(message, message.getAllRecipients()); transport.close(); When I look at the html format sent with the above code. I get the following: <!DOCTYPE html><html><body><img src="http://en.wikipedia.org/wiki/Krka_National_Park#mediaviewer/File:Krk_waterfalls.jpg> How to make sure the user will not be able to see any html code or URL link like the mail sent by LOOKOUT?

  • How to connect my Android to my Laptop wirelessly , to stream data between the two?

    - by Deepun
    I want to stream data from my Laptop PC to my Android phone using TCP or UDP by creating sockets in both the phone and the laptop, but it has to be done wirelessly. How do I connect them to stream the data ? I thought creating an ad-hoc wireless network from my laptop and connecting to it using my Android would work. But my Android is not detecting the ad-hoc network. Is there any other way how I can connect the two ? I downloaded this software called 'connectify' and created a wifi hotspot on my laptop, and successfully connected the two. But will I be able to stream data to my device using this connection ? Can simple direct Bluetooth connection help me in creating sockets in both phone and laptop and stream the data ?

  • How can I get the Android SDK working with Eclipse in Ubuntu 9.10 64-bit?

    - by user30667
    I would like to tinker with the Android software development kit, and I have found out that it only support 32-bit versions of the Java Platform and Eclipse. I installed the ia32 Sun Java runtime environment and the 32-bit version of Eclipse. I also used the update-alternatives program to make a java 32-bit preference. Both of these seem to run fine. I also installed the Eclipse android plugins, but my problem lies in the SDK downloaded from Google. When I go to Eclipse preferences and try to tell it about my Android SDK location, there are no SDK targets listed. Has anyone else gotten this running on Ubuntu 9.10 64-bit? Thanks.

  • What options exist when the vendor does not supply an ADB driver for an Android device?

    - by STATUS_ACCESS_DENIED
    So I bought an Android phone and the vendor does not offer any drivers whatsoever. The Android SDK and the drivers that come with it don't seem to work with the device, but the device itself reports as Android 2.2.1. Other users have reported that the drivers of the Nook Color worked for them, but I cannot confirm this, after trying. What options do I have to connect to the device (and ultimately to root it)? Is it truly just the .inf file that I need to manipulate in order to make the device ID known to Windows? After all there are tools to figure out those strings while the device is connected (although "unknown") ...

  • kSOAP2 and SOAPAction on Android

    - by Matze
    Hi everyone, I am trying to access a Webservice with kSOAP2 on an Android Phone. I think the connection is being established, but the server won't answer my request since I'm not providing a SOAP Action Header which seems to be required in SOAP Version 1.1(please correct me if I'm wrong here) which I have to use since the server does not support Version 1.2 . The concrete Faultcode which is returning in the request looks like this: faultactor null faultcode "S:Server" (id=830064966432) faultstring "String index out of range: -11" (id=830064966736) The errorcode which is generated on the server (I'm running it on a localhost) looks like this: 4.05.2010 20:20:29 com.sun.xml.internal.ws.transport.http.HttpAdapter fixQuotesAroundSoapAction WARNUNG: Received WS-I BP non-conformant Unquoted SoapAction HTTP header: http://server.contextlayer.bscwi.de/createContext 24.05.2010 20:20:29 com.sun.xml.internal.ws.server.sei.EndpointMethodHandler invoke SCHWERWIEGEND: String index out of range: -11 java.lang.StringIndexOutOfBoundsException: String index out of range: -11 at java.lang.String.substring(Unknown Source) at de.bscwi.contextlayer.xml.XmlValidator.isValid(XmlValidator.java:41) at de.bscwi.contextlayer.server.ContextWS.createContext(ContextWS.java:45) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.xml.internal.ws.api.server.InstanceResolver$1.invoke(Unknown Source) at com.sun.xml.internal.ws.server.InvokerTube$2.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.EndpointMethodHandler.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.SEIInvokerTube.processRequest(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Unknown Source) at com.sun.xml.internal.ws.server.WSEndpointImpl$2.process(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter$HttpToolkit.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handleExchange(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.AuthFilter.doFilter(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) The relevant part of the WSDL (at least that's what I'm thinking) looks like this: <operation name="createContext"> <soap:operation soapAction=""/> - <input> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </input> - <output> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </output> </operation> In my code I'm adding a Header, but it seems like I'm doing it wrong: private static final String SOAP_ACTION = ""; //...

My first progressbar is hidden but the second one is not displayed. I think I've done somthing wrong using the threads and handlers but I dont' know why. I was first using handler.sendMessage in place of handler.handleMessage but when I had several task in my connectionManager, the progressbar was updated only at the end of all tasks. Thank you in advance for your help

In my main code, firstly I create a JSONObject (I have cut it down here for this example): JSONObject j = new JSONObject(); j.put("engineer", "me"); j.put("date", "today"); j.put("fuel", "full"); j.put("car", "mine"); j.put("distance", "miles"); Next I pass the object over for sending, and receive the response: String url = "http://www.server.com/thisfile.php"; HttpResponse re = HTTPPoster.doPost(url, j); String temp = EntityUtils.toString(re.getEntity()); if (temp.compareTo("SUCCESS")==0) { Toast.makeText(this, "Sending complete!", Toast.LENGTH_LONG).show(); } The HTTPPoster class: public static HttpResponse doPost(String url, JSONObject c) throws ClientProtocolException, IOException { HttpClient httpclient = new DefaultHttpClient(); HttpPost request = new HttpPost(url); HttpEntity entity; StringEntity s = new StringEntity(c.toString()); s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); entity = s; request.setEntity(entity); HttpResponse response; response = httpclient.execute(request); return response; } This gets a response, but the server is returning a 403 - Forbidden response. I have tried changing the doPost function a little (this is actually a little better, as I said I have alot to send, basically 3 of the same form with different data - so I create 3 JSONObjects, one for each form entry - the entries come from the DB instead of the static example I am using). Firstly I changed the call over a bit: String url = "http://www.orsas.com/ServiceMatalan.php"; Map<String, String> kvPairs = new HashMap<String, String>(); kvPairs.put("vehicle", j.toString()); // Normally I would pass two more JSONObjects..... HttpResponse re = HTTPPoster.doPost(url, kvPairs); String temp = EntityUtils.toString(re.getEntity()); if (temp.compareTo("SUCCESS")==0) { Toast.makeText(this, "Sending complete!", Toast.LENGTH_LONG).show(); } Ok so the changes to the doPost function: public static HttpResponse doPost(String url, Map<String, String> kvPairs) throws ClientProtocolException, IOException { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(url); if (kvPairs != null && kvPairs.isEmpty() == false) { List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(kvPairs.size()); String k, v; Iterator<String> itKeys = kvPairs.keySet().iterator(); while (itKeys.hasNext()) { k = itKeys.next(); v = kvPairs.get(k); nameValuePairs.add(new BasicNameValuePair(k, v)); } httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); } HttpResponse response; response = httpclient.execute(httppost); return response; } Ok So this returns a response 200 int statusCode = re.getStatusLine().getStatusCode(); However the data received on the server cannot be parsed to a JSON string. It is badly formatted I think (this is the first time I have used JSON): If in the php file I do an echo on $_POST['vehicle'] I get the following: {\"date\":\"today\",\"engineer\":\"me\"} Can anyone tell me where I am going wrong, or if there is a better way to achieve what I am trying to do? Hopefully the above makes sense!

  • android spinning image

    - by user270811
    hi, i am trying to create two spinning wheels, as in pulleys, so everytime the attached rope moves, the two pulleys will rotate. i have tried two approaches: 1) use Matrix.postRotate within the onDraw() method of the View class, which calls the following: private void drawSpinningWheel(Canvas canvas) { try { canvas.save(); Bitmap bitmapOrg = null; int iDrawable = R.drawable.spinning_button; bitmapOrg = BitmapFactory.decodeResource(getResources(), iDrawable); if(bitmapOrg != null) { int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 24; int newHeight = 24; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); matrix.postRotate((float) mDegrees++); Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); canvas.drawBitmap(resizedBitmap, matrix, null); } canvas.restore(); } catch(Exception e) { Log.e(TAG + "drawSpinningWheel", e.getMessage()); } } but it seems like the image not only spins but rotates around another axis 2) use SurfaceView and a separate thread, in the run() call this: private void doDraw(Canvas canvas) { // Draw the background image. Operations on the Canvas accumulate // so this is like clearing the screen. canvas.drawBitmap(mBackgroundImage, 0, 0, null); int yTop = mCanvasHeight - ((int) mY + mSpinningWheelImageHeight / 2); int xLeft = (int) mX - mSpinningWheelImageWidth / 2; ... // Draw the ship with its current rotation canvas.save(); canvas.rotate((float) mHeading++, (float) mX, mCanvasHeight - (float) mY); mSpinningWheelImage.setBounds(xLeft, yTop, xLeft + mSpinningWheelImageWidth, yTop + mSpinningWheelImageHeight); mSpinningWheelImage.draw(canvas); canvas.restore(); } i get the spinning to work but i can't add another spinning wheel. i even tried to create another thread for the second spinning wheel, only one shows up. can someone point me in the right direction? thanks.

  • android: two issues using Tablerow+TextView in Tablelayout

    - by Yang
    I am using Tablerow+TextView to make a simple view for blog posts and their replies. In each TableRow I put a TextView in. Now I have two issues: The text which is longer than the screen won't automatically wrap up to be multi-line. Is it by design of TableRow? I've already set tr_content.setSingleLine(false); [update] This has been addressed, I think I should change Fill_parent to be Wrap_content in textView.tr_author_time.setLayoutParams(new LayoutParams( LayoutParams.**WRAP_CONTENT**, LayoutParams.WRAP_CONTENT)); The Table won't scroll like ListView. My rows are more than the screen size. I expect the table could be scrolled down for viewing just like ListView. Is that possible? Here is my code: TableLayout tl = (TableLayout) findViewById(R.id.article_content_table); TextView tr_title = new TextView(this); TextView tr_author_time = new TextView(this); TextView tr_content = new TextView(this); TableRow tr = new TableRow(this); for(int i = 0; i < BlogPost.size(); i++){ try{ // add the author, time tr = new TableRow(this); /////////////////add author+time row BlogPost article = mBlogPost.get(i); tr_author_time = new TextView(this); tr_author_time.setText(article.author+"("+ article.post_time+")"); tr_author_time.setTextColor(getResources().getColor(R.color.black)); tr_author_time.setGravity(0x03); tr_author_time.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); tr.addView(tr_author_time); tl.addView(tr,new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); ////////////////////// then add content row tr = new TableRow(this); tr_content = new TextView(this); tr_content.setText(article.content); tr_content.setSingleLine(false); tr_content.setGravity(0x03); tr_content.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); tr.addView(tr_content); tr.setBackgroundResource(R.color.white); tl.addView(tr,new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); }

  • Android - Saving an object in onSaveInstanceState?

    - by Donal Rafferty
    I have created a small XML parsing application for Android that displays information in a listview and then allows a user to click on the list view and a dialog with further info will pop up. The problem is that when the screen orientation is changed when a dialog screen is open I get a null pointer error. The null pointer occurs on the following line: if(setting.getAddForPublicUserNames() == 1){ This line is part of my dialogPrepare method: @Override public void onPrepareDialog(int id, Dialog dialog) { switch(id) { case (SETTINGS_DIALOG) : afpunText = ""; if(setting.getAddForPublicUserNames() == 1){ afpunText = "Yes"; } else{ afpunText = "No"; } String Text = "Login Settings: " + "\n" + "Password: " + setting.getPassword() + "\n" + "Server: " + setting.getServerAddress() + "\n" + "Register: " + setting.getRegistrarAddress() + "\n" + "Realm: " + setting.getRealm() + "\n" + "Public UserNames: " + afpunText + "\n" + "Preference Settings: " + "\n" + "Request VDN: " + setting.getRequestVDN() + "\n" + "Handover Settings: " + "\n" + "Enable Handover: " + setting.getEnableHandover() + "\n" + "Hand Over Number: " + setting.getHandoverNum() + "\n"; AlertDialog settingsDialog = (AlertDialog)dialog; settingsDialog.setTitle("Auth ID: " + setting.getUserName()); tv = (TextView)settingsDialog.findViewById(R.id.detailsTextView); if (tv != null) tv.setText(Text); break; } } So the error is that my variable setting is null after the screen orientation changes. I have tried to use the onSaveInstance state methods to fix that as follows: @Override public void onSaveInstanceState(Bundle savedInstanceState) { for(int i = 0; i < settings.size(); i++){ savedInstanceState.putString("Username"+i, settings.get(i).getUserName()); savedInstanceState.putString("Password"+i, settings.get(i).getPassword()); savedInstanceState.putString("Server"+i, settings.get(i).getServerAddress()); savedInstanceState.putString("Registrar"+i, settings.get(i).getRegistrarAddress()); savedInstanceState.putString("Realm"+i, settings.get(i).getRealm()); savedInstanceState.putInt("PUserNames"+i, settings.get(i).getAddForPublicUserNames()); savedInstanceState.putString("RequestVDN"+i, settings.get(i).getRequestVDN()); savedInstanceState.putString("EnableHandOver"+i, settings.get(i).getEnableHandover()); savedInstanceState.putString("HandOverNum"+i, settings.get(i).getHandoverNum()); } super.onSaveInstanceState(savedInstanceState); } and @Override public void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); //Check to see if this is required // Restore UI state from the savedInstanceState. // This bundle has also been passed to onCreate. for(int i = 0; i<settings.size(); i++){ settings.get(i).setUserName(savedInstanceState.getString("Username"+i)); settings.get(i).setPassword(savedInstanceState.getString("Password"+i)) ; settings.get(i).setServerAddress(savedInstanceState.getString("Server"+i)); settings.get(i).setRegistrarAddress(savedInstanceState.getString("Registrar"+i)); settings.get(i).setRealm(savedInstanceState.getString("Realm"+i)); settings.get(i).setAddForPublicUserNames(savedInstanceState.getInt("PUserNames"+i)); settings.get(i).setRequestVDN(savedInstanceState.getString("RequestVDN"+i)); settings.get(i).setEnableHandover(savedInstanceState.getString("EnableHandOver"+i)); settings.get(i).setHandoverNum(savedInstanceState.getString("HandOverNum"+i)); } } However the error still remains, I think I have to save the selected setting from what was selected from the ListView? But how do I save a setting object in onSavedInstance?
