Larry in Canada recently sent me an email asking a Delphi XE5 mobile multi-device question: “How do you include files and/or folders containing files with a Delphi Android application APK file?” I told him I would create a simple example and explain how to deploy a file with your application and then access it from a Delphi app for iOS and Android. To accomplish this, you create a new mobile app, write one or more lines of code, the Project | Deployment menu item, and use the System.IOUtils unit’s TPath.GetDocumentsPath method and PathDelim in your code.
The steps I followed to create my sample mobile app
1) File | New | FireMonkey Mobile Application – Delphi and used the “Blank Application” project template.
2) On the form, I added 1 TButton, 2 TLabel, and 1 TImage component.
3) I double clicked on the TButton component to create the OnClick event handler.
4) I added a “uses System.IOUtils;” just below the {$R *.fmx} in the implementation section.
5) I added the following code in the event handler to display the documents path and to load the bitmap from the documents folder:
1 2 3 4 5 |
procedure TForm1.Button1Click(Sender: TObject); begin DocPathLabel.Text := TPath.GetDocumentsPath; Image1.Bitmap.LoadFromFile(TPath.GetDocumentsPath + PathDelim + 'davidi_tiedye.jpg'); end; |
6) In the Project Manager, I added Android and iOS Target Platforms so that I can build for each of the two platforms.
7) Using the Project | Deployment menu item, I chose the Android and the iOS Device platforms and for each one I clicked on the “Add Files” button in the local toolbar to select the bitmap file I want to deploy with my app and set the Remote Path column value:
-
- For Android, set the Remote Path to
assetsinternal
-
- For iOS, set the Remote Path to
StartUpDocuments
Here are screenshots of each of the resulting deployment settings:
7) Compile, Deploy and Run the app on Android (I used my Samsung Galaxy S4) and iOS (I used my iPhone 4s) producing the following result when I click on the Button:
