为“自定义文件"声明 MIME 类型将通过蓝牙发送 [英] Declaring MIME type for a "custom file" that is to be Sent via Bluetooth

问题描述

我真的需要帮助来解决这个问题:

I really need help in solving this issue:

我正在开发一个应用程序，以使用蓝牙将文件从我的应用程序传输到其他手机.当我想传输一个图像文件时，我的部分代码如下:

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.

安卓清单文件如下:

 <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>

代码运行良好.现在我的问题是:同样，我想发送一个由以下行创建的文件:

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());

文件名应该是这样的:

   card12434247.Xcard

现在需要对我上面发布的代码进行哪些修改?我应该如何在意图过滤器中编写 mimeType?

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

应该是什么线:

  intent.setType(...)?

我应该如何修改它以便蓝牙能够处理这个文件

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

  xyz.Xcard ??

我应该如何声明通过蓝牙发送我的文件所需的自定义 mime 类型?

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

推荐答案

尝试将文件放在蓝牙目录中，它对我有用.

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"));
