声明MIME类型为＆QUOT;自定义文件＆QUOT;即通过蓝牙发送 [英] declaring mime type for a "custom file" that is to be sent via bluetooth

问题描述

我真的需要解决这个问题的帮助：

I really need help in solving this issue:

我开发一个应用程序使用蓝牙我的应用程序到其他手机传输文件。当我想传送一个图像文件，我的code中的一部分去如下：

I am developing an application to transfer a file from my application to other phone using Blue-tooth. When I wanted to transfer an image file, the part of my code went as follows:

     intent.setType("image/*");
     i.putExtra(i.EXTRA_STREAM, uri);
     //here uri has the URI of the image that I want to send.

和Android清单文件去如下：

And the android manifest File went as Follows:

 <intent-filter>

       <action android:name="android.intent.action.MAIN"

       <category android:name="android.intent.category.LAUNCHER" />
       <category android:name="android.intent.category.BROWSABLE" />

       <data android:scheme="file" />
       <data android:mimeType="image/*" />
       <data android:host="*" />


 </intent-filter>

和code正常工作。现在的问题是： 同样地，我想发送由下面的行中创​​建的文件：

And code worked fine. Now my question is : Similarly I want to send a file that is created by the following line:

   f = File.createTempFile("card", ".XCard", getExternalCacheDir());

该文件的名称将是这样的：

The name of the file would be something like this:

   card12434247.Xcard

现在哪些修改需要在code，我张贴以上？ 我应该如何写在意向过滤器MIMETYPE？

Now what modifications are required in the code that I posted above? How should I write the mimeType in the intent-filter?

应该是什么行：

  intent.setType(...)?

我应该如何修改它，以便蓝牙将能够处理这个文件

How should I modify it so that bluetooth will be able to handle this file

  xyz.Xcard ??

我应该如何申报，将被要求送我的文件通过蓝牙发送自定义MIME类型？ 需要它？ 请帮助！

How should I declare the custom mime type that will be required to send my file to be sent via Blue-tooth? Is it required?? Please help!!

推荐答案

尝试把文件中的蓝牙目录中，它为我工作。

Try to put the file in the bluetooth directory, it worked for me.

String root = Environment.getExternalStorageDirectory().toString();
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/html");
File f = new File(root + "/bluetooth/test2.html");
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(f));
startActivity(Intent.createChooser(i, "Send page"));
