在Android的开放.msg文件（Outlook项目文件）编程 [英] Opening .msg file(Outlook item file) in android programmatically

问题描述

我想通过我的应用程序打开一个.msg文件。我试着用设置MIMETYPE为 vnd.ms-前景，不过我还是没能打开.msg文件如我所料，然后我试图与安装相同.MSG电子邮件和在我的设备打开。它开始像一个魅力。

I am trying to open a .MSG file through my application. I tried with setting the MIMETYPE as vnd.ms-outlook, still i couldn't able to open up the .MSG file as i expected, then i tried with attaching the same .MSG in email and opened in my device. It opened like a charm.

所以我的问题是，我怎么能开辟Android的.msg文件编程中的应用程序。

So my question is , How can i open up the .MSG file in android programmatically within the application.

试着用下面的方法，

方法1：手动设置MIMETYPE

Method 1 : Setting the MIMETYPE manually

mimetype = "application/vnd.ms-outlook";

方法二：通过 MimeTypeMap

String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString());
String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension); // extension is msg

通过其他安装的应用程序打开.msg文件

Opening the .MSG file through another installed application

Log.i(TAG, "Extension :" + extension + "\n" + "MIME :" + mimetype); // Prints msg for extension and mimetype = application/vnd.ms-outlook for method 1 and null when i use method 2
intent.setDataAndType(Uri.fromFile(file),mimetype);
startActivity(intent);

在方法2结果无效的MIMETYPE并设置明确的太不工作的媒体类型。

The mimetype in Method 2 results null and the mimetype set explicitly too doesn't work.

任何人可以分享他们的想法解决这个问题。

Could anybody share their thoughts on solving this issue.

感谢。

推荐答案

您应该使用的意图，与其他应用程序打开该文件。试试这个：

You should use an intent to open the file with another app. Try this:

Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(msgURI, mimeTypeString);
startActivity(i);

这应该允许已注册在其清单味精的数据类型将其打开任何应用程序。

That should allow any app that has registered the MSG's data type in its manifest to open it.
