  • android content provider robustness on provider crash

    - by user1298992
    On android platforms (confirmed on ICS), if a content provider dies while a client is in the middle of a query (i.e. has a open cursor) the framework decides to kill the client processes holding a open cursor. Here is a logcat output when i tried this with a download manager query that sleeps after doing a query. The "sleep" was to reproduce the problem. you can imagine it happening in a regular use case when the provider dies at the right/wrong time. And then do a kill of com.android.media (which hosts the downloadProvider). "Killing com.example (pid 12234) because provider com.android.providers.downloads.DownloadProvider is in dying process android.process.media" I tracked the code for this in ActivityManagerService::removeDyingProviderLocked Is this a policy decision or is the cursor access unsafe after the provider has died? It looks like the client cursor is holding a fd for an ashmem location populated by the CP. Is this the reason the clients are killed instead of throwing an exception like Binders when the server (provider) dies ?

  • Why am I seeing a crash when trying to call CDHtmlDialog::OnInitDialog()

    - by Tim
    I added a helpAbout menu item to my mfc app. I decided to make the ddlg derive from CDHTMLDialog. I override the OnInitDialog() method in my derived class and the first thing I do is call the parent's OnInitDialog() method. I then put in code that sets the title. On some machines this works fine, but on others it crashes in the call to CDHtmlDialog::OnInitDialog() - Trying to read a null pointer. the call stack has nothing useful - it is in mfc90.dll Is this a potential problem with mismatches of mfc/win32 dlls? It works on my vista machines but crashes on a win2003 server box. BOOL HTMLAboutDlg::OnInitDialog() { // CRASHES on the following line CDHtmlDialog::OnInitDialog(); CString title = "my title"; // example of setting title // i try to get version info //set the title CModuleVersion ver; char filename[ _MAX_PATH ]; GetModuleFileName( AfxGetApp()->m_hInstance, filename, _MAX_PATH ); ver.GetFileVersionInfo(filename); // get version from VS_FIXEDFILEINFO struct CString s; s.Format("Version: %d.%d.%d.%d\n", HIWORD(ver.dwFileVersionMS), LOWORD(ver.dwFileVersionMS), HIWORD(ver.dwFileVersionLS), LOWORD(ver.dwFileVersionLS)); CString version = ver.GetValue(_T("ProductVersion")); version.Remove(' '); version.Replace(",", "."); title = "MyApp - Version " + version; SetWindowText(title); return TRUE; // return TRUE unless you set the focus to a control } And here is the relevant header file: class HTMLAboutDlg : public CDHtmlDialog { DECLARE_DYNCREATE(HTMLAboutDlg) public: HTMLAboutDlg(CWnd* pParent = NULL); // standard constructor virtual ~HTMLAboutDlg(); // Overrides HRESULT OnButtonOK(IHTMLElement *pElement); HRESULT OnButtonCancel(IHTMLElement *pElement); // Dialog Data enum { IDD = IDD_DIALOG_ABOUT, IDH = IDR_HTML_HTMLABOUTDLG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support virtual BOOL OnInitDialog(); DECLARE_MESSAGE_MAP() DECLARE_DHTML_EVENT_MAP() }; I can't figure out what is going on - why it works on some machins and crashes on others. Both have VS2008 installed EDIT: VS versions VISTA - no crashes 9.0.30729.1 SP 2003 server: (crashes) 9.0.21022.8 RTM

  • Best approach for a flexible layout for ASP.NET application

    - by Rohith Nair
    I am looking for a best approach for designing a dynamic page. I want my users to be able to determine the position of set of controls to be loaded into a page. Should be able to add new controls or swap in and out new controls into an existing page. Eg: Portal based applications,iGoogle kind of websites I am afraid that I will be re-inventing the wheel if I go and create a portal structure for my web application. There are a couple of things in my mind to look into: Good third-party suites which can do the same Should I look into Silverlight RIA application? I have researched about the Infragistics and Telerik controls and the price is high for just a control like LayoutManager which I need. Any alternatives? What is the best approach for this kind of situation, to add to the list?

  • Design review for application facing memory issues

    - by Mr Moose
    I apologise in advance for the length of this post, but I want to paint an accurate picture of the problems my app is facing and then pose some questions below; I am trying to address some self inflicted design pain that is now leading to my application crashing due to out of memory errors. An abridged description of the problem domain is as follows; The application takes in a “dataset” that consists of numerous text files containing related data An individual text file within the dataset usually contains approx 20 “headers” that contain metadata about the data it contains. It also contains a large tab delimited section containing data that is related to data in one of the other text files contained within the dataset. The number of columns per file is very variable from 2 to 256+ columns. The original application was written to allow users to load a dataset, map certain columns of each of the files which basically indicating key information on the files to show how they are related as well as identify a few expected column names. Once this is done, a validation process takes place to enforce various rules and ensure that all the relationships between the files are valid. Once that is done, the data is imported into a SQL Server database. The database design is an EAV (Entity-Attribute-Value) model used to cater for the variable columns per file. I know EAV has its detractors, but in this case, I feel it was a reasonable choice given the disparate data and variable number of columns submitted in each dataset. The memory problem Given the fact the combined size of all text files was at most about 5 megs, and in an effort to reduce the database transaction time, it was decided to read ALL the data from files into memory and then perform the following; perform all the validation whilst the data was in memory relate it using an object model Start DB transaction and write the key columns row by row, noting the Id of the written row (all tables in the database utilise identity columns), then the Id of the newly written row is applied to all related data Once all related data had been updated with the key information to which it relates, these records are written using SqlBulkCopy. Due to our EAV model, we essentially have; x columns by y rows to write, where x can by 256+ and rows are often into the tens of thousands. Once all the data is written without error (can take several minutes for large datasets), Commit the transaction. The problem now comes from the fact we are now receiving individual files containing over 30 megs of data. In a dataset, we can receive any number of files. We’ve started seen datasets of around 100 megs coming in and I expect it is only going to get bigger from here on in. With files of this size, data can’t even be read into memory without the app falling over, let alone be validated and imported. I anticipate having to modify large chunks of the code to allow validation to occur by parsing files line by line and am not exactly decided on how to handle the import and transactions. Potential improvements I’ve wondered about using GUIDs to relate the data rather than relying on identity fields. This would allow data to be related prior to writing to the database. This would certainly increase the storage required though. Especially in an EAV design. Would you think this is a reasonable thing to try, or do I simply persist with identity fields (natural keys can’t be trusted to be unique across all submitters). Use of staging tables to get data into the database and only performing the transaction to copy data from staging area to actual destination tables. Questions For systems like this that import large quantities of data, how to you go about keeping transactions small. I’ve kept them as small as possible in the current design, but they are still active for several minutes and write hundreds of thousands of records in one transaction. Is there a better solution? The tab delimited data section is read into a DataTable to be viewed in a grid. I don’t need the full functionality of a DataTable, so I suspect it is overkill. Is there anyway to turn off various features of DataTables to make them more lightweight? Are there any other obvious things you would do in this situation to minimise the memory footprint of the application described above? Thanks for your kind attention.

  • Is creating a full application in Silverlight advisable?

    - by Anthony
    Is creating a huge public site fully in Silverlight really advisable? for eg. an ecommerce site. I don't want to start any debate but actually I feel Silverlight shouldn't be used for full website because the biggest loss you incur is of SEO. No search engines till today can parse the xap file and index it based on it's content. You can get around it by doing ifs and thens like if Silverlight is not supported then make an Asp.Net equivalent page for it but that only doubles our effort of making application, more than anything else. Why write double code in 2 applications meant for the same purpose. If that is the only option why not create Asp.Net application only. What are your views? Thanks in advance :)

  • Unable to start the web application from localhost:3000(ruby on rails)

    - by vipin8169
    I had created a demo web application by executing rails tickets and then i executed rails script/server to run it on localhost. Initially i was able to execute the application in the browser by typing localhost:3000 in the address bar, but then I deleted the folder tickets from my hard disk. Now again i created the same folder but when i try to run it using the same command rails script/server it says that vverma@l-vverma:~/railsExp/tickets$ rails script/server create File exists - script/server I tried deleting the script/server file but i still couldn't run the localhost:3000 in the browser Tried rails s as well, it gave the following output:- http://paste.ubuntu.com/1317610/ But still i was unable to run the app on 'localhost:3000' What is the solution to this

  • _resignRootViewController causes app to crash.

    - by RickiG
    [MainViewController _resignRootViewController]: message sent to deallocated instance 0x4ebfe50 This error happens when I try to pop my MainViewController Object from within it self: - (void) switchToTableView { //a method on the MainViewController [self.navigationController popViewControllerAnimated:NO]; [[UIApplication applicationDelegate] switchToTableView]; //convenience method for the app delegate } The debugger stops at the [super dealloc] command in MainViewControllers dealloc method. I do the exact same thing in the TripTableViewController, but here it never crashes. MainViewController and TripTableViewController are handled in my AppDelegate like this: - (void) switchToTableView { TripTableViewController *tripTableViewController = [[TripTableViewController alloc] init]; [[self.navigationController navigationBar] setHidden:NO]; [self.navigationController pushViewController:tripTableViewController animated:NO]; [tripTableViewController release]; } - (void) switchToScrollView { MainViewController *scrollView = [[MainViewController alloc] init]; [[self.navigationController navigationBar] setHidden:YES]; [self.navigationController pushViewController:scrollView animated:NO]; [scrollView release]; } I am trying to achieve that when the user goes from TripTableViewController to MainViewController; TripTableViewController is released/popped and visa versa for the MainViewController. I do not wish for the navigationController to make the decision about when to pop/cache/release them, this is why I try to do it from within it self. I have not been able to find the _resignRootViewController mentioned anywhere. My guess is that it is a delegate message sent by a ViewController that resigns as rootViewController for a navigationController and that somehow it is called twice, once before MainViewCOntroller is released/popped and somehow again afterwards. Have any one else seen this error message before? Google and the Apple Docs does not mention it? How can I debug such an error? Hope someone can guide me in the right direction on this one, Thanks:)

  • JNI 'problmatic frame' causes JVM to crash

Example of such convenient application center - android market, ... . Ubuntu 11.10 have pretty/sexy center but .... vital function still missed.

  • Close application on error

    - by poke
    I’m currently writing an application for the Android platform that requires a mounted SD card (or ExternalStorage). I know that it might not be the best way to require something like that, but the application will work with quite a lot of data, and I don’t even want to think about storing that on the device’s storage. Anyway, to ensure that the application won’t run without the external storage, I do a quick check in the activity’s onCreate method. If the card is not mounted, I want to display an error message and then quit the application. My current approach looks like this: public void onCreate ( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); try { // initialize data storage // will raise an exception if it fails, or the SD card is not mounted // ... } catch ( Exception e ) { AlertDialog.Builder builder = new AlertDialog.Builder( this ); builder .setMessage( "There was an error: " + e.getMessage() ) .setCancelable( false ) .setNeutralButton( "Ok.", new DialogInterface.OnClickListener() { public void onClick ( DialogInterface dialog, int which ) { MyApplication.this.finish(); } } ); AlertDialog error = builder.create(); error.show(); return; } // continue ... } When I run the application, and the exception gets raised (I raise it manually to check if everything works), the error message is displayed correctly. However when I press the button, the application closes and I get an Android error, that the application was closed unexpectedly (and I should force exit). I read some topics before on closing an application, and I know that it maybe shouldn’t happen like that. But how should I instead prevent the application from continuing to run? How do you close the application correctly when an error occurs?

  • Crash on replacing map annotations

    - by Alwin
    Solved it, see below code I'm trying to replace annotations on my MapView depending on the distance between user location and annotation. The annotations are getting replaced like they should, but when I touch te mapview my app crashes. This is de code I have so far: NSMutableArray *tempArray = [[NSMutableArray alloc] init]; for (id object in self.mapAnnotations) { if([object isKindOfClass:[ClosedAnnotation class]]) { ClosedAnnotation *ann = (ClosedAnnotation *)object; CLLocation *tempLocation = [[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance <= 1.0){ [mapView removeAnnotation:object]; OpenAnnotation *openAnnotation = [[OpenAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:openAnnotation]; [tempArray addObject:openAnnotation]; [openAnnotation release]; } else { [tempArray addObject:object]; } } else if([object isKindOfClass:[OpenAnnotation class]]){ OpenAnnotation *ann = (OpenAnnotation *)object; CLLocation *tempLocation = [[[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude] autorelease]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance > 1.0){ [mapView removeAnnotation:object]; ClosedAnnotation *closedAnnotation = [[ClosedAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:closedAnnotation]; [tempArray addObject:closedAnnotation]; [closedAnnotation release]; } else { [tempArray addObject:object]; } } } [self.mapAnnotations removeAllObjects]; [self.mapAnnotations addObjectsFromArray:tempArray]; [tempArray release]; I solved it by getting rid of the complete "two-class"-structure and handling everything within one annotation class. Works like a charm now.
