I want to create an Fmx C++ component for Android (inherited from TComponent). This component must have a "color" property with TAlphaColor type. I want to see that "color" property in the property editor, displayed in a color picker with color icon (not as a unsigned int).

Скажите пожалуйста, вы решили этот вопрос и как?
Пришлите мне, пожалуйста, пример.

Dear SVTX, say me please, do you solve this question? And can you share solution?

Can anyone say me how to use DLL with FMX form  into old C++ Builder 2007?

I have created fmx DLL with Fmx form. (Rad Studio 10.3.3)
Build with release configuration. 
Project->Options->C++ Linker ->Link with Dynamic RTL = false
Project->Options->Runtime Packages ->Link with runtime packages = false

I have also created VCL Project (C++ Builder 2007), added a form. OnButton click I am calling my DLL function, who show the FMX form. On another button I am calling freeLibrary.
All ok, my FMX form has shown, but on FormClose my appliction is crashing and I can not close my app. I am only able to close my app from the task manager.

Hi dear Embarcadero team!
I'm using Embarcadero RAD Studio 10.3 C++ and I have a big problem.
There is a Google Play requirement - https://developer.android.com/distribute/best-practices/develop/64-bit
I saw the "RAD Studio Roadmap" - https://community.idera.com/developer-tools/b/blog/posts/august-2019-delphi-android-beta-plans-august-roadmap-update
There is shown, that Rad Studio 10.4(10.4.x) will support 64-bit android only for Delphi.
Say me please, when will Rad Studio support 64-bit android for C++ , and what to do until C++ 64-bit android support?

P.S. Send me official link, if it posible.

Say me please, how I can take photo from camera or gallery, without saving picture to gallery.
"NeedSaveToAlbum" do not help. (Rad studio 10.2.1)

I do all as - http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Taking_and_Sharing_Pictures_and_Text_Using_Action_Lists

Hello !!!
I want onButtonClick create popup. I use TPopup component. All good, but on android "Back button" click closing forma. But I want close popup (when popup is shown).

//---------------------------------------------------------------------------------

void __fastcall  btn3PointsClick(TObject *Sender)
{
    PopUpSettings->IsOpen = true;
    PopUpSettings->PlacementTarget = btn3Points;
    PopUpSettings->BringToFront();
}

//-------------------------------------------------------------------------------------

void __fastcall FormCloseQuery(TObject *Sender, bool &CanClose)
{
    try {
        if (PopUpSettings->IsOpen == true) {
            CanClose = false;
        }
        else {
            CanClose = true;
        }

    } __finally {
        PopUpSettings->IsOpen = false;
    }
}

//-------------------------------------------------------------------

All is fine, when

#ifdef TARGET_OS_MAC
    #include "zlib.h"
#else
    #include "System.ZLib.hpp"
#endif

but if zconf.h (in line 377) will be error, change that line --> typedef System::Byte  FAR Bytef;

Thank you for all. 

Thank you. That is, there is no universal solution ???
Can may be solution with Android API ??

Thanks for all links.

 I have LAN printer (Posiflex PP 6900), It have a IP(192.168.xx.xx).
 With TIdTCPClient component I can print text.
 But when I send for example myicon.png  stream, printer was not recognise that is image, and printing myicon.png text .

    IdTCPClient->Host = "192.168.xx.xx";
    IdTCPClient->Port = 9100;
    IdTCPClient->Connect();
    IdTCPClient->Socket->Write("\n ----------------------");
    IdTCPClient->Socket->Write("\n Hello from mobile !!!!");
    IdTCPClient->Socket->Write("\n ----------------------");
    IdTCPClient->Disconnect();

I do not want use Google cloud. Have any idea print custom document (for example .rtf, .pdf) without Google cloud ????

Thanks for link. But don't want with google cloud.

How to print text from Android (IOS) device ? (C++ Rad Studio 10.2)

With USB printer and other types printers (WiFi, Bluetooth ....)

Скажите пожалуйста, как проверить состояние сети (Rad Studio 10.2).

Say me please, what to do ????

I work with Rad Studio 10.2 Tokyo + OsX 10.11 El Capitan + XCode 8 (C++).
When I use System::Zlib::compressBound function ( #include "System.ZLib.hpp" ), I have linker error --> [ILINK32 Error] Error: Unresolved external 'System::Zlib::compressBound(unsigned int)' referenced from C:\User\...\...\Unit1.o.

Попробуйте на событие OnMouseDown делать ListBox1.HitTest:=False, а на OnMouseUp  ListBox1.HitTest:=True

не помагает

Нашлось какое то решение, не хорошое но работает.

OnMouseDown делаем клон оригинальной  ListBox - а, clonListBox  делаем  BringToFront, а  потом начинаем сваю работу на clonListBox.  

В канце (OnMouseUp)  clonListBox  отображаем  на оригинал  и  удаяем  clonListBox  .

Вот тестовый проект , правда,  нужны каррекции. (Rad Studio 10)

TestListBoxItmDrag.rar

на весь экран создаю  TLayout, а потом на этом  TLayout- е двигаю Bitmap.

Layout1->BringToFront();
Application->ProcessMessages(); не помагает
пока не вызывается MouseUp,  вертикальный скролл TListBox- а работает

Так и сделала, он MouseDown создала Bitmap с скриншотом  TListBoxItem и двигаю этот Bitmap . Но  вертикальный скролл TListBox- а мешает . И не как не могу  сделать так, что пока  я двигаю этот Bitmap, вертикальный скролл TListBox- а не работала. 

скажите пожалуйста , как реализовать Drag and Drop  TListBoxItem на Андроид (Rad Studio 10)

#include <Androidapi.JNI.JavaTypes.hpp>
#include <Androidapi.Helpers.hpp>
#include <Androidapi.JNI.Embarcadero.hpp>
#include <Androidapi.JNI.GraphicsContentViewText.hpp>

for Rad Studio 10

Сам спросил - сам отвечаю.

Вот реализация на Delphi:

var
  intent: JIntent;
  uri: Jnet_Uri;
begin
  Intent := TJIntent.Create;
  Intent.setAction(TJIntent.JavaClass.ACTION_VIEW);

  uri := TJnet_Uri.JavaClass.fromFile(TJFile.JavaClass.init(StringToJString(TPath.Combine(TPath.GetDownloadsPath, 'app.apk'))));
  Intent.setDataAndType(uri, StringToJString('application/vnd.android.package-archive'));
  Intent.setFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NEW_TASK);
  SharedActivity.startActivity(Intent);
end;

Эта штука запускает установку app.apk, лежащего в GetDownloadsPath(). Но это не тихая установка и требует подтверждению юзера.

Думаю для копилки знаний этот код будет полезен, однако мой вопрос о тихой установке все еще открыт.

 

P.S.

Почему то более простая конструкция:

Intent.setDataAndType(StrToJURI(TPath.Combine(TPath.GetDownloadsPath, 'app.apk')),  StringToJString('application/vnd.android.package-archive'));

не сработала.

_di_JIntent newIntent = TJIntent::Create();
    newIntent->setAction(TJIntent::JavaClass->ACTION_VIEW);
    _di_JMimeTypeMap mime = TJMimeTypeMap::JavaClass->getSingleton();
    _di_JString ExtToMime = mime->getMimeTypeFromExtension(StringToJString(L"apk"));
    String pth = System::Ioutils::TPath::GetPublicPath() + L"/app.apk";   // path app.apk
    _di_JFile my_file = TJFile::JavaClass->init(StringToJString(pth));
    _di_Jnet_Uri uri = TJnet_Uri::JavaClass->fromFile(my_file);
    newIntent->setDataAndType(uri,ExtToMime);
    int my_flag = TJIntent::JavaClass->FLAG_ACTIVITY_NEW_TASK;
    newIntent->setFlags(flag);
    SharedActivity()->startActivity(newIntent);
