Hi, I've solved my problem by changing a line in my TDataWedgeBroadcastListener.Create: TAndroidHelper.Context.registerReceiver(FReceiver, LIntentFilter,2); instead of TAndroidHelper.Context.registerReceiver(FReceiver, LIntentFilter); the value "2" corresponds to the Andoid flag RECEIVER_EXPORTED. Thanks for the help

Hello, 1. I used logcat and only two error messages appear in 450 lines but the log continues after these errors: 2. The cause of the problem could be related to the following warnings: This RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED flag was introduced as part of Android 13 and seems to be now a requirement for apps running on Android 14 or higher. 3. The app compiled with Delphi 10 works perfectly on Android 10, 11, 12, 13 and 14 without this RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED flag !?!? 4. The app compiled with Delphi 12.1 works perfectly on Android 10, 11, 12, displays a wrong splashscreen on Android13 (icon of the app and not the splashscreen) but works perferctly and crashes at startup on Android 14!!! 5. I created a new project "Hello word" with Delphi12.1 and the app works on Android 14 withoud add a notion of RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED flag 6. I created a new project with Dephi12.1 and I imported the original project files of my app (unit1.pas, etc) and the app crashes on Android 14 Does anyone have any experience with Delphi, Android 14 and this notion of RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED flag?

Hello, I have a problem migrating an Android app from Delphi10.3 to Delphi12.1: 1. I had to modify the permissions management because the app was making errors at compilation 2. I had to reset the Manifest And now on Android 10,11,12, it works, but on Android 14, the app launches, displays the splashscreen and then closes! Does anyone have an idea how to solve this problem? Thanks in advance

I already use ListBox.Items.BeginUpdate and ListBox.Items.EndUpdate. This reduced the display of 1,000 ListBox items from 30 seconds to 6 seconds. As already written, what's wrong is adding one listboxitem after another in a loop. This is equivalent to an action for each item. If you assign a Listobject to the Listbox, it's a single action. I've tested the assignment method; it's immediate, but I can only do it for the main ListBox field. My question is whether it's possible to make an assignment that updates the other two ListBox fields by making a single assignment for the ListBox, or an assignment for each of the 3 fields, which would make it possible to do 3 actions at worst instead of 1000.

Hi, Thank for your answer Martifan. The code is actually written in Delphi. I tested your solution and I get exactly the same time to perform the operation as my best solution (6 sec for 1 000 items!). The following operation takes far too long because it adds one ListBoxItem after another for i := 0 to DataList.Count - 1 do begin ... ListBoxItem.StylesData['Reference.text'] := DataList[i].Definition; ListBoxItem.StylesData['Qty1.text'] := DataList[i].Qty1; ListBoxItem.StylesData['Qty2.text'] := DataList[i].Qty2; If I use a "Listbox.assign(ListObject)", the delay for 1 000 items goes from more than 6 sec to 500 millisec because all ListBoxItem are added in one shot. The problem is that only the field Reference of ListBoxItems is completed... The question is .... Is it possible to fill in the other fields of a ListBoxItem using an assign function?

Hi, 1. If I don't use Livebindings, it's because I can't use Livebindings (the source is a dataset > I extract some columns of this dataset to display these in a visual component) 2. This speed problem occurs with all visual components (Combobox, Listbox, etc...) 3. I've already solved a similar problem with combobox: Dataset > Stringlist > Listbox.assign(Stringlist). For 1000 lines, the delay goes from more than 30 sec to 500 millisec!. In the case of the Listbox, I don't have just one dimension, but two: not just lines, but lines made up of 3 distinct fields.

Hi, In an Android app, I'm retrieving some data (3 columns) from a dataset and need to display it in a Listbox with 3 fields in each line. If I use the following procedure in a loop, adding one line after another, it works for about ten lines, but when it comes to displaying a hundred lines, the process is too slow. ... ListBox1.BeginUpdate; try for i:=0 ... ... AddListBoxItem(Listbox1,value1[i],value2[i],value3[i]); ... end; finally ListBox1.EndUpdate; end; //********************* procedure TForm1.AddListBoxItem(myListBox:TListBox;Definition, Qty1, Qty2:string); begin ... ListBoxItem:= TListBoxItem.Create(myListBox); ListBoxItem.Parent:= myListBox; ListBoxItem.ApplyStyleLookup; ListBoxItem.StylesData['Reference.text']:=Definition; ListBoxItem.StylesData['Qty1.text']:=Qty1; ListBoxItem.StylesData['Qty2.text']:=Qty2; ... end; It's much faster if the data extracted from the dataset are placed in a Stringlist and I transmit the data to the listbox in a single operation using "myListBox:=myStringList". In this case, the values are only in the 1st field of the listbox. How can I perform the same kind of operation to put the data in ListBox fields 2 and 3?

This solution has a note "Asked 8 years, 9 months ago"... 8 years ago, what version of Windows was in use? Do we have the same ie sources in a Windows OS 8 years ago and in Win11?

To give a WebBrowser1.Silent := True; to suppress script errors is not a solution!!!!! I have the same problem with the Delphi 11.3 sample called "WebBrowser" running on Win11. It is impossible to load a website (even bing.com!!!) without these script errors. And "do not display these errors" does not prevent malfunctions of the website!!!! So I'm reactivating the question, does anyone know why the Webbrowser sample is unable to play javascripts and is there a solution? Since these are samples provided by Embarcadero itself, we shouldn't even have to ask this question 😞 --- If anyone wonders why you insist on using delphi to display a website, I'd like to point out that the latest versions of Chrome and Edge (and maybe others) have changed their popup management, making many sites unusable without any prior announcement that I'm aware of!

Hello, I use Delphi to develop applications for Android devices and I have a customer who asks that one of my Android applications be adapted to Apple i-phones. After doing some research, it seems that this is quite complicated to do: 1. You need an Apple device to compile the Delphi code 2. Then you have to register with Apple and submit the application for acceptance 3. You can only distribute the app from the Apple Store 4. Then there seems to be licensing issues to pay to Apple (the developer has to pay but also the end customer! Indeed, it seems that for professional apps, our customer who will use our app will have to pay each year a license to Apple for an app that was never created by Apple) If anyone has experience in this area, I would be happy to hear from them: - What are the minimum Apple devices required to transpose an Android app to an i-phone app? - What are the steps to take with Apple? - Is this story about the Apple license to be paid by the final customer true and what is its cost? Thanks for your help

1. To have specific links, just type "Delphi 10.3 Android11" in Google For instance: https://stackoverflow.com/questions/67453524/why-is-delphi-10-3-app-crashing-in-android-11 2. Personally I haven't tried it but according to some comments on the web an empty app compiled on Delphi 10.3 crashes on Android11

I give myself the answer to my question so that it can be useful to others 🙂 I found in the code that handles image capture 2 problems related to the changes made by Delphi 10.4: 1. A unit of the ZXing library has an error following the change of the indexing of the characters of a string (mystring[0] in Delphi10.3 becomes mystring[1] in Delphi10.4) 2. The management of the .free (a .free in Delphi 10.3 which must be removed because in Delphi 10.4, the release of a parent object automatically releases its children objects

No, I don't think it's a problem of hardware or configuration. We have tested on many devices (smartphones and tablets of different manufacturers) and we always have the same behavior. In fact, just do a search on the web and you'll find many people who have had exactly the same problem. On our side, we took the same original code (with some adaptations due to the changes brought by Delphi 10.4, for example the 1st character of a string becomes mystring[1] while before it was mystring[0]) and compiled it with Delphi 10.4. The result is? The app compiled with Delphi 10.4 works on all Android versions. So there is a problem between Delphi10.3 and Android11.

Hi, I am facing a problem that many people have already noticed. I have an app developed with Delphi 10.3.3 that works perfectly on all Android (7,8,9,10 and 12) but crashes on Android11: After splashscreen display, the app stops. The app crashes on Android 11 but it works on Android 12 when it is the same .apk file. Does anyone know the cause? Thanks for your help

Hi, I had an Android app developed in Delphi 10.3 that scanned barcodes via the smartphone camera and the ZXing library. After switching to Delphi 10.4, the project was able to compile without any problem but the picture taking frequently crashes: It works sometimes and often the app freezes and you have to wait for a timeout for Android to ask if you don't want to close the application (same behaviour on Android 9, 10, 11). There must have been changes in Delphi 10.4 that cause this problem. Does anyone have an idea of such a change in Delphi 10.4 that could be the cause of this problem? Thanks for your help
