  • Loading Flash / Flex Applications in another AIR Application

    - by t.stamm
    Hi there, i'm loading a Flex Application in my AIR App and i'm using the childSandboxBridge and parentSandboxBridge to communicate between those two. Works like a charm. But i've tried to load a Flash Application (the main Class extends Sprite, not Application) and therefore i get a SecurityError when trying to set the childSandboxBridge on the loaderInfo object. In the Flex app it's like this: I'm casting the loaderInfo since the childSandboxBridge Property is only available in AIR. loaderInfo = FlexGlobals.topLevelApplication.systemManager.loaderInfo; try { Object(loaderInfo).childSandboxBridge = this; } catch(e:Error) { ... } In my Flash app it's like this: loaderInfo = myMainObject.loaderInfo; // myMainObject is the same class as 'root' try { Object(loaderInfo).childSandboxBridge = this; } catch(e:Error) { ... } In the below example i get the following SecurityError: Error #3206: Caller app:/airapp.swf/[[DYNAMIC]]/1 cannot set LoaderInfo property childSandboxBridge. The SecuritySandbox for both examples is 'application'. Any ideas why it doesn't work with the Flash app? Thanks in advance.

  • Weird output of Throwable getMessage()

    - by Ravi Gupta
    Hi I have below pseudo code with throws an exception like this throw new MyException("Bad thing happened","com.stuff.errorCode"); where MyException extends Exception class. So the problem is when I try to get the message from MyException class by calling myEx.getMessage() it returns ???en_US.Bad thing happened??? instead of my original message i.e. Bad thing happened I have checked that MyException class doesn't overrides Throwable class's getMessage() behavior. Below is the how the call passes from MyException.getMessage() to Throwable.getMessage() public MyException(String msg, String sErrorCode){ super(msg); this.sErrorCode = sErrorCode; this.iSeverity = 0; } which then calls public Exception(String message) { super(message); } and finally public Throwable(String message) { fillInStackTrace(); detailMessage = message; } when I do a getMessage on myexception it calls Throwable's getMessage as below public String getMessage() { return detailMessage; } So ideally it should return the original message as I set when throwing the exception. What's the ???en_US thing ?

  • ListView causing OutOfMemory Error

    - by Michael
    So I am not really given a reason to the right of this error message. I am not exactly sure why this is happening but my guess though is that it has to do with the fact that there are around ~50 good quality drawables. Upon scrolling really fast, the app crashes. I feel as if I am mitigating most common issues with ListView and crashing such as using View Holders as well as only initiating the inflater once. Process: com.example.michael.myandroidappactivity, PID: 20103 java.lang.OutOfMemoryError at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) Here is the code public class ImageAdapter extends BaseAdapter { private Context context; private ArrayList<Integer> imageIds; private static LayoutInflater inflater; public ImageAdapter(Context _context, ArrayList<Integer> _imageIds) { context = _context; imageIds = _imageIds; } @Override public int getCount() { return imageIds.size(); } @Override public Object getItem(int position) { return null; } @Override public long getItemId(int position) { return 0; } static class ViewHolder{ ImageView img; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; View rowView = null; if(rowView==null) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); rowView = inflater.inflate(R.layout.listview_layout, parent, false); holder = new ViewHolder(); holder.img = (ImageView) rowView.findViewById(R.id.flag); rowView.setTag(holder); } else { holder = (ViewHolder) rowView.getTag(); } holder.img.setImageResource(imageIds.get(position)); return rowView; } }

  • Runnable to be run every second only runs once in Fragment onCreateView()

    - by jul
    I'm trying to update the time in a TextView with a Runnable supposed to be run every second. The Runnable is started from a Fragment's onCreateView(), but it's only executed once. Anybody can help? Thanks public class MyFragment extends Fragment { Calendar mCalendar; private Runnable mTicker; private Handler mHandler; TextView mClock; String mFormat; private boolean mClockStopped = false; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { RelativeLayout view = (RelativeLayout) inflater.inflate(R.layout.meteo_widget, container, false); /* * Clock (from DigitalClock widget source) */ mClock = (TextView) view.findViewById(R.id.clock); mCalendar = Calendar.getInstance(); mHandler = new Handler(); mTicker = new Runnable() { public void run() { if(mClockStopped) return; mCalendar.setTimeInMillis(System.currentTimeMillis()); mClock.setText(DateFormat.format("hh:mm:ss", mCalendar)); mClock.invalidate(); long now = SystemClock.uptimeMillis(); long next = now + (1000 - now % 1000); mHandler.postAtTime(mTicker, next); } }; mTicker.run(); return view; } @Override public void onResume() { super.onResume(); mClockStopped = true; } @Override public void onPause() { mClockStopped = false; super.onPause(); } }

  • How to properly set button phase after dragging over button?

    - by irobeth
    I have a class (mxml) that extends Button while implementing drag/drop support. When I drag one of them onto another, the drag receiver stays stuck in its 'over' phase until I click on it (As if something about DragManager.acceptDragDrop is preventing the MouseEvent from getting to button) Is there a way to make a button re-evaluate its phase after the drop? I've tried fabricating a MouseEvent and sending it to rollOverHandler with no luck. This resembles the scenario in Button.as (lines 2606-2647) described like Drag over and up mouse down while out of Button roll over Button - stay in "up" phase mouse up while over Button - "over" phase continue with step 2 of first three sequences above This is my drag/drop handler private function dragDropHandler(event:DragEvent):void { trace("dropped"); var ib : IconButton = (event.dragInitiator as IconButton); if(this.data is Section) { if(ib.data is Item) { trace("ITEM"); //move an item into a section. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } else if(ib.data is Section) { trace("SECTION"); //change a section's parent. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } } //you can only drag stuff into sections. }

  • Download dynamic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason I think it does not know how to stream file to the client when I'm using RPC: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl. Do I really need to make a servlet or it is possible to stream it back with my RPC?

  • PDO using singleton stored as class properity

    - by Misiur
    Hi again. OOP drives me crazy. I can't move PDO to work. Here's my DB class: class DB extends PDO { public function &instance($dsn, $username = null, $password = null, $driver_options = array()) { static $instance = null; if($instance === null) { try { $instance = new self($dsn, $username, $password, $driver_options); } catch(PDOException $e) { throw new DBException($e->getMessage()); } } return $instance; } } It's okay when i do something like this: try { $db = new DB(DB_TYPE.':host='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASS); } catch(DBException $e) { echo $e->getMessage(); } But this: try { $db = DB::instance(DB_TYPE.':host='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASS); } catch(DBException $e) { echo $e->getMessage(); } Does nothing. I mean, even when I use wrong password/username, I don't get any exception. Second thing - I have class which is "heart" of my site: class Core { static private $instance; public $db; public function __construct() { if(!self::$instance) { $this->db = DB::instance(DB_TYPE.':hpost='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASS); } return self::$instance; } private function __clone() { } } I've tried to use "new DB" inside class, but this: $r = $core->db->query("SELECT * FROM me_config"); print_r($r->fetch()); Return nothing. $sql = "SELECT * FROM me_config"; print_r($core->db->query($sql)); I get: PDOStatement Object ( [queryString] => SELECT * FROM me_config ) I'm really confused, what am I doing wrong?

  • Android: Help with tabs view

    - by James
    So I'm trying to build a tabs view for an Android app, and for some reason I get a force close every time I try to run it on the emulator. When I run the examples, everything shows fine, so I went as far as to just about copy most of the layout from the examples(a mix of Tabs2.java and Tabs3.java), but for some reason it still wont run, any ideas? Here is my code(List1.class is a copy from the examples for testing purposes). It all compiles fine, just gets a force close the second it starts: package com.jvavrik.gcm; import android.app.TabActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.TabHost; import android.widget.TextView; public class GCM extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("g", getResources().getDrawable(R.drawable.star_big_on)) .setContent(new Intent(this, List1.class))); tabHost.addTab(tabHost.newTabSpec("tab2") .setIndicator("C") .setContent(new Intent(this, List1.class)) ); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("S") .setContent(new Intent(this, List1.class)) ); tabHost.addTab(tabHost.newTabSpec("tab4") .setIndicator("A") .setContent(new Intent(this, List1.class)) ); } }

  • How to place images on top of each other in java

    - by Haxed
    Hi, I have a background image of a road, which I have displayed on a JFrame using an ImageIcon. I want to put a car on top of that background image at a certain (x,y) location. I tried using another ImageIcon and the background does not appear when I run the program , however the car does. import javax.swing.ImageIcon; import javax.swing.JFrame; import javax.swing.JLabel; public class Gui extends JFrame { private ImageIcon northcar = new ImageIcon("src/north.gif"); private ImageIcon usIcon = new ImageIcon("src/trafficLight.jpg"); public Gui() { add(new JLabel(usIcon)); // background image does not appear after the i added the northcar label add(new JLabel(northcar)); // this picture can be seen } public static void main(String[] args) { Gui frame = new Gui(); frame.setTitle("TestImageIcon"); frame.setLocationRelativeTo(null); // Center the frame frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setBounds(0, 0, 650, 650); frame.setVisible(true); } } I heard about using a canvas but have no clue. Any ideas ? Many Thanks

  • How to force positioned elements to stay withing viewable browser area?

    - by jessegavin
    I have a script which inserts "popup" elements into the DOM. It sets their top and left css properties relative to mouse coordinates on a click event. It works great except that the height of these "popup" elements are variable and some of them extend beyond the viewable area of the browser window. I would like to avoid this. Here's what I have so far <script type="text/javascript"> $(function () { $("area").click(function (e) { e.preventDefault(); var offset = $(this).offset(); var relativeX = e.pageX - offset.left; var relativeY = e.pageY - offset.top; // 'responseText' is the "popup" HTML fragment $.get($(this).attr("href"), function (responseText) { $(responseText).css({ top: relativeY, left: relativeX }).appendTo("#territories"); // Need to be able to determine // viewable area width and height // so that I can check if the "popup" // extends beyond. $(".popup .close").click(function () { $(this).closest(".popup").remove(); }); }); }); }); </script>

  • Android: onListItemClick not opening up the .xml file

    - by Capsud
    Hi, public void onListItemClick(ListView l, View v, int position, long id) { if(position == 0){ setContentView(R.layout.cuisine); } } I have an array of Strings and i'm using the above method to try and open up a new xml file called 'cuisine' when it is clicked. but it keeps failing! Have I done this right, or what am I doing wrong? Thanks. Ok from looking at similar problems on the web, people have said to get the onListItemClick() to start a new activity and using that new activity to then open up the new view? So what i've done is this... protected void onListItemClick(ListView l, View v, int position, long id) { Intent dundrumIntent = new Intent(v.getContext(), DundrumSelector.class); dundrumIntent.putExtra("position", position); startActivityForResult(dundrumIntent, 0); } and then import android.app.Activity; import android.os.Bundle; public class DundrumSelector extends Activity { @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); int position = getIntent().getExtras().getInt("position"); if(position == 0){ setContentView(R.layout.cuisine); } } } Yet i'm still getting the same problem. The program crashes when I click on an item in the listView. And yes i've added the activity to the manifest. Does anyone have a resolution to this as alot of people seem to be having the same problem. Thanks alot.

  • Java: Generics, Class.isaAssignableFrom, and type casting

    - by bguiz
    This method that uses method-level generics, that parses the values from a custom POJO, JXlistOfKeyValuePairs (which is exactly that). The only thing is that both the keys and values in JXlistOfKeyValuePairs are Strings. This method wants to taken in, in addition to the JXlistOfKeyValuePairs instance, a Class<T> that defines which data type to convert the values to (assume that only Boolean, Integer and Float are possible). It then outputs a HashMap with the specified type for the values in its entries. This is the code that I have got, and it is obviously broken. private <T extends Object> Map<String, T> fromListOfKeyValuePairs(JXlistOfKeyValuePairs jxval, Class<T> clasz) { Map<String, T> val = new HashMap<String, T>(); List<Entry> jxents = jxval.getEntry(); T value; String str; for (Entry jxent : jxents) { str = jxent.getValue(); value = null; if (clasz.isAssignableFrom(Boolean.class)) { value = (T)(Boolean.parseBoolean(str)); } else if (clasz.isAssignableFrom(Integer.class)) { value = (T)(Integer.parseInt(str)); } else if (clasz.isAssignableFrom(Float.class)) { value = (T)(Float.parseFloat(str)); } else { logger.warn("Unsupporteded value type encountered in key-value pairs, continuing anyway: " + clasz.getName()); } val.put(jxent.getKey(), value); } return val; } This is the bit that I want to solve: if (clasz.isAssignableFrom(Boolean.class)) { value = (T)(Boolean.parseBoolean(str)); } else if (clasz.isAssignableFrom(Integer.class)) { value = (T)(Integer.parseInt(str)); } I get: Inconvertible types required: T found: Boolean Also, if possible, I would like to be able to do this with more elegant code, avoiding Class#isAssignableFrom. Any suggestions? Sample method invocation: Map<String, Boolean> foo = fromListOfKeyValuePairs(bar, Boolean.class);

You've helped me out a lot as this is incredibly important (i.e. me passing my degree). The problem now is: The program works correctly when nothing but the GameBoard class is added to the JApplet, however, when I try to add the ScoreBoard class, both Panel classes do not show on the Applet. I'm guessing this is now down to positioning? Any ideas? EDIT: Gone back to the previously asked question Hovercraft, and found it was due to the layout of the contentPane and the order at with the components were added. Thanks to all of you so much. People like you make the development community a bit of alright.

    My string.xml: <!--I try to bold my argument %s, like below:--> <string name="hello">Hello to: <b>%s</b> !</string> My layout main.xml: <LinearLayout ...> <TextView android:id="@+id/hello_txt" ... .../> </LinearLayout> My Fragment class: public class MyFragment extends Fragment{ TextView helloTxt; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { super.onCreateView(inflater, container, savedInstanceState); helloTxt = (TextView) findViewById(R.id.hello_txt); } @Override public void onStart() { super.onStart(); //pass "Monday" as the argument to my string helloTxt.setText(String.format(getString(R.string.hello), "Monday")); } } When I run my app on my device, I got "Hello to: Monday !" displaying on screen, but the "Monday" is not bold, but I used <b> in my string.xml.

  • stop android emulator call

    - by Shahzad Younis
    I am working on an Android application, having functionality like voicemail. I am using BroadcastReceiver to get dialing events. I have to get the event "WHEN CALL IS UNANSWERED (not picked after few rings) FROM RECEIVER". I will do some actions on caller end against this event. I am using AVD emulator, and I do call from one instance to another instance and it calls perfectly, but the problem is: It continuously calls until I reject or accept the call. This way I cannot detect that "CALL IS UNANSWERED AFTER A NUMBER OF RINGS". So I want the Caller emulator to drop the call after a number of rings (if unanswered) like a normal phone. I can do it (drop the call after some time) by writing some code, but I need the natural functionality of phone in the emulator. Can anyone please guide me? Is there any settings in the emulator? Or something else? The code is shown below in case it helps: public class MyPhoneReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle extras = intent.getExtras(); if (extras != null) { String state = "my call state = " + extras.getString(TelephonyManager.EXTRA_STATE); Log.w("DEBUG", state); } }

  • Pass a Message From Thread to Update UI

    - by Jay Dee
    Ive created a new thread for a file browser. The thread reads the contents of a directory. What I want to do is update the UI thread to draw a graphical representation of the files and folders. I know I can't update the UI from within a new thread so what I want to do is: whilst the file scanning thread iterates through a directories files and folders pass a file path string back to the UI thread. The handler in the UI thread then draws the graphical representation of the file passed back. public class New_Project extends Activity implements Runnable { private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { Log.d("New Thread","Proccess Complete."); Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); } }; public void getFiles(){ //if (!XMLEFunctions.canReadExternal(this)) return; pd = ProgressDialog.show(this, "Reading Directory.", "Please Wait...", true, false); Log.d("New Thread","Called"); Thread thread = new Thread(this); thread.start(); } public void run() { Log.d("New Thread","Reading Files"); getFiles(); handler.sendEmptyMessage(0); } public void getFiles() { for (int i=0;i<=allFiles.length-1;i++){ //I WANT TO PASS THE FILE PATH BACK TU A HANDLER IN THE UI //SO IT CAN BE DRAWN. **passFilePathBackToBeDrawn(allFiles[i].toString());** } } }
