编程通过蓝牙传输图像 [英] Programmatically transfer images through bluetooth

问题描述

如何从一台设备在Android中发送图片文件到另一个使用蓝牙编程。我正确地发送文本文件，但试图发送图像文件时，它会显示错误。

How to send a image file from one device to another using bluetooth in Android programmatically. I Can send text files correctly,but when trying to send image files it shows error.

样code是在这里：

ContentValues values = new ContentValues();

  values.put(BluetoothShare.URI, url);

  values.put(BluetoothShare.DESTINATION, deviceAddress);

  values.put(BluetoothShare.DIRECTION, BluetoothShare.DIRECTION_OUTBOUND);

  Long ts = System.currentTimeMillis();

  values.put(BluetoothShare.TIMESTAMP, ts);

  getContentResolver().insert(BluetoothShare.CONTENT_URI, values);

下面网​​址指的是图片的路径。

Here url refers to the path of the image.

推荐答案

您可以使用此code这个问题：

you can use this code for this problem :

 File file=new File(imagePath);
 Uri uri=Uri.fromFile(file);

 ContentValues values = new ContentValues();

  values.put(BluetoothShare.URI, uri.toString());

  values.put(BluetoothShare.DESTINATION, deviceAddress);

  values.put(BluetoothShare.DIRECTION, BluetoothShare.DIRECTION_OUTBOUND);

  Long ts = System.currentTimeMillis();

  values.put(BluetoothShare.TIMESTAMP, ts);

  getContentResolver().insert(BluetoothShare.CONTENT_URI, values);
