Delphi XE5如何透過URL呼叫Android或iOS上的其他程式?

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 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.

Facebook大當機?

晚上突然發現Facebook不能留言、按讚等更新狀態….結果才發現是全球性的問題。希望能快快好起來!

Facebook status update problems aren’t uncommon, but this one seems global — we’ve tested it from several IPs, receiving the same message.

In addition to status update issues, we were also unable to Like or post photos on Facebook.

According to web service status tracker Downrightnow, Facebook is currently likely experiencing a service disruption.

We’ve contacted Facebook about the issue but have not yet received a response.

Stay tuned for updates.
