FireMonkey Changes for XE8 FireMonkey is our proprietary library of object-oriented programming (classes, methods, properties and so forth).
 
Native Presentation of TListView, TSwitch, and TMemo on iOS On the iOS target platform, FireMonkey now supports both styled and native presentations for the TListView, TSwitch, and TMemo controls.
 
By default, when you add any of these components to the Form Designer, RAD Studio uses the styled presentation.
To use the native presentation on the iOS target platform, set the new ControlType property to Platform.
For more information, see TPresentedControl.ControlType and FireMonkey Native iOS Controls.
 
Desktop Web BrowsersOn desktop platforms (Windows and Mac OS X), FireMonkey now supports the use of the TWebBrowser component. All basic functions of the Web browser are available (such as navigate to URL, go back, go forward, and so on).
 
Standard Actions for TMediaPlayer FireMonkey now provides the following standard actions that you can use to control any instance of TMediaPlayer:
 
TMediaPlayerStart
TMediaPlayerStop
TMediaPlayerPlayPause
TMediaPlayerCurrentTime
TMediaPlayerVolume
New and Changed FireMonkey API New OnFilter Event FireMonkey provides the new OnFilter event to set custom filters in a search box.
 
For further information about the new OnFilter event, visit TCustomListView.OnFilter and TSearchBoxModel.OnFilter.
 
FMX Field Variables Now Start with F The names of all field variables in FMX classes now start with the letter F. This is according to the standard described in the Object Pascal Style Guide.
 
Some examples are:
 
FEnabledInteractiveGestures
FFont
FDesignInteractive
Run-Time Library (RTL) Changes for XE8 Changes in LongInt and LongWord Size for 64-bit iOS Platforms LongInt and LongWord are now platform-dependent integer types.
 
On 64-bit iOS platforms, LongInt and LongWord double their size compared to the size on 32-bit platforms (32-bit Windows, OSX32, 32-bit iOS, and Android) and 64-bit Windows platforms, as follow:
 
Size
32-bit platforms and 64-bit Windows platforms 64-bit iOS platforms
LongInt 32-bits (4 bytes) 64-bits (8 bytes)
LongWord
32-bits (4 bytes) 64-bits (8 bytes)
 
For more information, see Platform-Dependent Integer Types.
 
New Delphi Data Types FixedInt and FixedUInt Two new platform independent 32-bit integer types are introduced in XE8:
 
FixedInt: 32-bit signed integer type.
FixedUInt: 32-bit unsigned integer type.
The size of FixedInt and FixedUInt is 32 bits across all 64-bit and 32-bit platforms.
 
For further information, see FixedInt and FixedUInt.
 
Beacon Support The RTL now supports the use of beacons. A beacon is a Bluetooth Low Energy device that includes some Manufacturer Specific Data in its advertising data, allowing any device that receives that information to identify the beacon device and calculate the distance to it without being paired or connected to it.
 
We support two available beacon formats:
 
iBeacon - the format defined by Apple
AltBeacon - an open format, known as Alternative beacon, which supports both Android and iOS
Using Beacons shows how to implement a beacon application.
 
VCL Changes for XE8 Delphi Changes for XE8 C++ Changes for XE8 IDE Changes for XE8 Multi-Device Preview With the new Multi-Device Preview, you can preview how your application looks on different devices. The Multi-Device Preview displays a preview of the design area on several devices at the same time. You can select the devices to preview.

To open the Multi-Device Preview window, choose View > Multi-Device Preview.
 
For further information about this feature, see Multi-Device Preview.
 
Run Your Apps on Any iOS Simulator The Target node of the iOS Simulator platform node of the Project Manager now shows the complete list of simulators supported by the Xcode installation on your Mac. The Project Manager also shows the iOS version of each simulator, and you can run your applications on a given device model running any one of the supported iOS versions.
 
Add Featured Files Opens Automatically When Necessary When you add to the Project Manager a file that may require you to add some featured files to the deployment configuration of your project, RAD Studio now opens a filtered view of the Add Featured Files dialog box, so that you can include the required features files in the deployment configuration of your project. See Add Featured Files Filtered List for more information.
 
Disabling Built-in RAD Studio Java Libraries for Android Using the Project Manager In XE8, the Project Manager lists the built-in RAD Studio Java libraries for Android, and you can disable any one of those libraries. To make your application lighter, you might choose to disable Java libraries that your application does not require. For more information, see Using the Built-in RAD Studio Java Libraries for Android.

In XE7, you could easily add custom Java libraries to your Android applications using the Project Manager. However, to remove unnecessary Java libraries that RAD Studio includes in Android applications by default, you had to manually create and deploy a custom classes.dex file.
 
Mercurial Version Control System Integrated in the IDE RAD Studio supports now a new version control system integrated in the IDE, for managing and tracking changes in your projects: Mercurial distributed version control system.
 
The History Manager now presents integrated Mercurial version control log information from your local repository. You can find more information of the tracked changes of your project in the Contents, Information and Differences tab.
 
You can use Mercurial to:
 
Clone a copy of your remote Mercurial repository and start working with it.
Commit your changes to your local repository.
Show remote repository log data for your project.
In XE8, some Git features have been added in the IDE:
 
Authenticate in your remote private repository.
Push your changes to the remote Git repository and pull changes, updating your working copy with the latest remote changes.
For more information about the version control systems integrated in the IDE, see:

Settings Migration Tool The new Settings Migration Tool provided with RAD Studio XE8 allows you to import and export configuration settings between RAD Studio and Appmethod as well as between different versions of the products.
 
With the Settings Migration Tool you can:
 
Export settings to a migration file: to generate an XML export file with .idesettings extension.
Import settings from a Migration File: to import the XML file with .idesettings extension.
Export settings to a newer RAD Studio version: to migrate the settings automatically to a newer RAD Studio version installed on the same machine.
You can find the migration.exe tool in the following path: C:\Program Files (x86)\Embarcadero\Studio\16.0\bin.
 
Visit the Settings Migration Tool page for more details.
 
Database and Connectivity Changes for XE8 FireDAC Changes New FireDAC Teradata Database native driver (TData) based on the Teradata Database ODBC driver. See Connect to Teradata Database.
FireDAC Sqlite driver is updated in XE8. For detailed information, see Connect to SQLite database (FireDAC).
Migrate your existing dbExpress applications to use newer database technologies such as FireDAC. For migration, see Migrating dbExpress Applications to FireDAC.
Follow the steps in DbExpress Application Migration (FireDAC) to migrate your dbExpress Delphi application.
Debugger Changes for XE8 Platform Assistant Changes for XE8 Command-Line Utility Changes for XE8 Application Samples Changes for XE8 Older Samples Removed at XE7 are Available on SourceForge and XE6 Docwiki See Older Product Samples for more information about accessing the older product samples that were removed from RAD Studio at XE7.
 
Changes in the Help New Offline Help System The offline help files delivered with RAD Studio are now in Microsoft Compiled HTML Help format, also known as CHM. For more information, see Help on Help - CHM. Previously, the offline help was delivered in H2 format and was viewed using Microsoft DExplore.
 
The Microsoft Compiled HTML Help viewer can only show offline help. To access the online help, you must either open the online help yourself, or click Current Wiki Page on the footer of any page of the offline help. You can no longer choose whether you want the offline help viewer to show the offline help or the online help.
 
You can create your own CMH help files and link them with RAD Studio, for further infomation see Providing Help for Your Component.
