Android: Datei öffnen mit Std. Anwendung

[greenmile]

Hey super, vielen Dank. Hier der Code für XE8:

Code:

Uses ... Androidapi.JNI.Webkit;

function GetMimeType(FFilename: String; IsLocalFile: Boolean): JString;
{$IFDEF ANDROID}
  var jstr: JString;
  const _Default = 'video/mp4';
begin
  Try
    result := StringToJString(_Default); // Standard
    If IsLocalFile then jstr := TJMimeTypeMap.JavaClass.getFileExtensionFromUrl(StringToJString(cFileUrlPrefix + FFilename))
    Else jstr := TJMimeTypeMap.JavaClass.getFileExtensionFromUrl(StringToJString(FFilename));
    if jstr <> nil then begin
      jstr := TJMimeTypeMap.JavaClass.getSingleton.getMimeTypeFromExtension(jstr);
      if jstr <> nil then result := jstr;
    end;
  Except
    Result := StringToJString(_Default);
  End;
end;
{$ELSE}
begin
  raise Exception.Create('Not supported!');
end;
{$ENDIF}

Function OpenVideo(const URL: string; IsLocalFile: Boolean): Boolean;
{$IFDEF ANDROID}
var
   Intent: JIntent;
begin
  Try
    Intent := TJIntent.Create;
    Intent.setAction(TJIntent.JavaClass.ACTION_VIEW);
    Intent.setFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NEW_TASK);
    If IsLocalFile then Intent.setDataAndType(TJnet_Uri.JavaClass.parse(StringToJString(cFileUrlPrefix + URL)), GetMimeType(URL,IsLocalFile) )
    Else Intent.setDataAndType(TJnet_Uri.JavaClass.parse(StringToJString(URL)), GetMimeType(URL,IsLocalFile) );
    SharedActivity.startActivity(TJIntent.JavaClass.createChooser(Intent, StrToJCharSequence('Bitte App auswählen...')));
    Result := true;
  Except
    Result := false;
  End;
end;
{$ELSE}
begin
  raise Exception.Create('Not supported!');
end;
{$ENDIF}
