Levin's Blog-林壽山的c# .net奇幻旅程

之前曾經分享過，手機版的Line可以透過 line://msg/<CONTENT TYPE>/<CONTENT KEY> 這樣的語法呼叫Line 的程式分享。

當然Delphi XE5也可以透過程式呼叫程式才對，在Jim McKeeth 的「Sending a URL to Another App on Android and iOS with Delphi XE5」文章有教您如何呼叫

• http, tel, sms, fb, mailto, twitter, geo…..

• 作者也分類成三種：
• 1. iOS跟Android都可以使用的URLs

• http://superlevin.ifengyuan.tw/
• tel://0921789779
• sms://hello_world
• http://twitter.com/superlevin (這個語法會直接打開Android上的Twitter Client程式)
• mailto://superlevin@gmail.com
• twitter://user?screen_name=superlevin
• fb://profile/705666540
  (可以透過　http://graph.facebook.com/（帳號）superlevin取得UID)

iOS特殊語法

• http://maps.apple.com?q=5617 Scotts Valley Drive, Scotts Valley, CA 95066 (需要URL encode)

Android特殊語法

• content://contacts/people/
• content://contacts/people/1
• geo://0,0?q=5617 Scotts Valley Drive, Scotts Valley, CA 95066
• geo://46.191200, -122.194400 (I think this one doesn’t like the URLEncode)

作者在文中有提到使用TidURL.URLEncode 。

[pascal]
unit OpenViewUrl;

interface

// URLEncode is performed on the URL
// so you need to format it protocol://path
function OpenURL(const URL: string; const DisplayError: Boolean = False): Boolean;

implementation

uses
IdURI, SysUtils, Classes, FMX.Dialogs,
{$IFDEF ANDROID}
FMX.Helpers.Android, Androidapi.JNI.GraphicsContentViewText,
Androidapi.JNI.Net, Androidapi.JNI.JavaTypes;
{$ELSE}
{$IFDEF IOS}
iOSapi.Foundation, FMX.Helpers.iOS;
{$ENDIF IOS}
{$ENDIF ANDROID}

function OpenURL(const URL: string; const DisplayError: Boolean = False): Boolean;
{$IFDEF ANDROID}
var
Intent: JIntent;
begin
// There may be an issue with the geo: prefix and URLEncode.
// will need to research
Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW,
TJnet_Uri.JavaClass.parse(StringToJString(TIdURI.URLEncode(URL))));
try
SharedActivity.startActivity(Intent);
exit(true);
except
on e: Exception do
begin
if DisplayError then ShowMessage(‘Error: ‘ + e.Message);
exit(false);
end;
end;
end;
{$ELSE}
{$IFDEF IOS}
var
NSU: NSUrl;
begin
// iOS doesn’t like spaces, so URL encode is important.
NSU := StrToNSUrl(TIdURI.URLEncode(URL));
if SharedApplication.canOpenURL(NSU) then
exit(SharedApplication.openUrl(NSU))
else
begin
if DisplayError then
ShowMessage(‘Error: Opening "’ + URL + ‘" not supported.’);
exit(false);
end;
end;
{$ELSE}
begin
raise Exception.Create(‘Not supported!’);
end;
{$ENDIF IOS}
{$ENDIF ANDROID}

end.
