Question

当我尝试将文件附加到电子邮件时，我得到一个java.io.FileNotFoundException：没有内容提供程序logcat输出。如果有人能告诉我我做错了什么或者我该做什么，那就太棒了。谢谢。

这是我将文件添加到电子邮件中的方式..：

Intent sendIntent = new Intent(Intent.ACTION_SEND);
                sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
                sendIntent.setType("video/3gp");
                sendIntent.setType("video/mp4");
                startActivity(sendIntent);

...这里是整个logcat错误输出：

Answer 1

也许你应该传递file:///sdcard/Video0006.mp4形式的uri。

Answer 2

你也可以试试这个：

Uri.fromFile(new File(your image path));

Answer 3

将位图保存到文件的方法

  private fun bitmapToFile(bitmap:Bitmap): Uri {
        // Get the context wrapper
        val wrapper = ContextWrapper(applicationContext)

        // Initialize a new file instance to save bitmap object
        var file = wrapper.getDir("Images",Context.MODE_PRIVATE)
        file = File(file,"${UUID.randomUUID()}.jpg")

        try{
            // Compress the bitmap and save in jpg format
            val stream:OutputStream = FileOutputStream(file)
            bitmap.compress(Bitmap.CompressFormat.JPEG,100,stream)
            stream.flush()
            stream.close()
        }catch (e:IOException){
            e.printStackTrace()
        }

        // Return the saved bitmap uri
        return Uri.parse(file.absolutePath)
    }

怎么做 - java.io.FileNotFoundException：没有内容提供者？
