I used minSdkVersion="14" in manifest. Works here on android 4.4.4 (older Honeywell 75e) I have a customer with Honeywell 70e and Android 4.0 but doesn't tried yet.

Have you tried to delete all Tfdconnection and Tsqlconnection? Still does not start? Do you open Tfdconnection at runtime after the service start-up? Or it's set active at design time? Toooooo many questions....

Some sort of compilation to an intermediate representation must be there. Not to machine code but something much faster than parsing every time the source. Otherwise it will be very slow. I use FastScript and there is a compilation before execution. Execution is dozens times faster than compilation.

I've put on github a project that is using standard libraries from Honeywell and Zebra to read barcodes on devices with Android. It's my first project on github and I just made a restructuring. I hope it's all there. https://github.com/CristianPeta/HandheldBarcodeReader

I tried to subclass the Activity in Java for Honeywell and doesn't work. No errors but doesn't start the scanner. Maybe my Java knowledge was not enough. I will give it an other try when I will have a little time.

Or directly if you don't need to add but to replace. Memo.Lines.LoadFromFile(FileName, TEncoding.ASCII);

My VMs are connected to network and 10.1 does complain if 10.2 or 10.3 are started in an other WM. Probably because every WM does have an other IP (VMware stuff). "Duplicate License Key found. The same license key is used on 192.168.136.152. Please install a separate license" But starts and works. But 10.2 and 10.3 doesn't say anything.

Running in 32 bit mode and accessing more than 4GB.... I thought this is a relic of an ancient era.

You don't think what? I don't think that new devices with 4GB and less are running in 64 bit mode. Only some exceptions. The vast majority are running in 32 bit mode.

I don't think so. 64 bit OS will use more memory than a 32 bit. With 2GB RAM it's better to run in 32 bit mode. I have a Samsung A10 (model SM-A105FN released 2019) with 2GB RAM and running in 32 bit mode. PS. It's running Android 9

There can't be a device with more than 4GB memory and 32 bit OS. You can take the cheapest with 6GB.

TLabel is not native: http://docwiki.embarcadero.com/Libraries/Rio/en/FMX.Controls.Presentation.TPresentedControl.ControlType

Too little details. Stock TLabel component doesn't work with right to left languages. I don't understand how it works on Android but if it does maybe on iOS is font related.

Here Google Search is gray (Available in Enterprise) and included in that 1 year subscription from EMBT, https://www.embarcadero.com/products/enterprise-connectors And you mean that this connection is not to a Google API? Why not? From Google API documentation: "Custom Search JSON API provides 100 search queries per day for free. If you need more, you may sign up for billing in the API Console. Additional requests cost $5 per 1000 queries, up to 10k queries per day." "The search results include the URL, title and text snippets that describe the result. In addition, they can contain rich snippet information, if applicable. " https://developers.google.com/custom-search/v1/overview

I started with Basic. The next was Z80 assembler. But assembler opened my eyes and is a base of understanding how things works. P.S. I can't imagine that someone can do a good thing in Spring4D for example without understanding CPU and memory. Also if someone does not have this knowledge working with C or C++ is a waste of time in my opinion. Then better Java.

You need first to understand what a pointer is and how things like pointers and other types are stored into memory. Maybe diving a little in assembler will help you to understand what is under the hood. I can't imagine a good programmer that don't know a little how CPU works or how things are stored into memory.

First you need to know the maximum length of "rn" and allocate that maximum from start. Something like this: popmsg: array[0..100] of ODBALMMSG2; and call it like this: FConnection.ErrHandle := cnc_rdalmmsg2(FConnection.ConnHandle, -1, rn, @popmsg[0]); This way you don't need pointers.

I see that Google Search is part of Enterprise Connectors from C-Data that is part of RAD Studio Enterprise and Architect editions now. Has someone tried this? https://www.embarcadero.com/products/enterprise-connectors

I think that if an image viewer is not complaining it's OK. Are there other things to check? And yes, I tried https://en.delphipraxis.net/uploads/monthly_2019_10/11.jpg.a7ea4fc99c1ad313a4ff4d986ba246c9.jpg with 3 different viewers and no complains.

I see that when you click on a form their Action is executed. Action property was probably published for someone that will find something useful in this.

"Vcl.Forms.TForm.Action inherits from Vcl.Controls.TControl.Action" It's for buttons and menu items. You select an action defined in a TActionList object (centralized actions). It's strange to have this for TForm but this is like in FMX where any control can be a container for any control.

It's like passing an object as const. You can do what you want with the object because const is only for the reference. P.S. But compiler can decide to put this const into a registry or pass as reference. Nice to track down bugs...

You haven't told us what TPath.GetDocumentsPath returns for you in 10.2. I suppose the same as in 10.3. And I suppose the same for TPath.GetSharedDocumentsPath. Do you see any difference between 10.2 and 10.3? Because targetSdkVersion is now 28 in your manifest and you need to ask permission for what you want to do. This is an Android OS request. Nothing to do with Delphi.
