当-java.io.FileNotFoundException: 没有内容提供程序时怎么办？

当我尝试将文件附加到电子邮件时，会得到一个 java.io.FileNotFoundException: No content Provider logcat output。 如果有人能告诉我我做错了什么或者我应该做什么，那就太好了。谢谢你。

这是我如何添加文件的电子邮件. :

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

... 这是整个 logcat 错误输出:

最佳答案

也许您应该传递一个形式为 file:///sdcard/Video0006.mp4的 uri。

小开

你也可以试试这个:

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

方法将位图保存到文件

  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)
}
小开

这招对我很管用

val uri:Uri =  File(path).toUri()
