I have an application in which I try to share a photo, but when you share the application it crashes.

  1.     val bitmap = (imageViewx1.drawable as BitmapDrawable).bitmap
  2.     val nombreArchivo:String="Shared.jpg"
  3.     val patchload= getExternalFilesDir(Environment.DIRECTORY_PICTURES).toString() + nombreArchivo
  4.     val mifile2 =File(patchload)
  5.     val stream: OutputStream = FileOutputStream(mifile2)
  6.     bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream)
  7.     stream.flush()
  8.     stream.close()
  9.     val shareIntent = Intent(Intent.ACTION_SEND)
  10.     shareIntent.type = "image/jpg"
  11.     val photoFile = File(filesDir, "PicturesShared.jpg")
  12.     Toast.makeText(this, photoFile.toString(), Toast.LENGTH_SHORT).show()
  13.     shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(photoFile))
  14.     startActivity(Intent.createChooser(shareIntent, "Share image using"))

答案1

得分: 1

抛出的异常是：

  1. android.os.FileUriExposedException: file:///storage/emulated/0/Android/data/app.xxxx.appimage/files/PicturesShared.jpg expobeyond app 通过 ClipData.Item.getUri() 共享

FileUriExposedException 是由以下原因引起的：

> 当应用向另一个应用公开 file:// Uri 时抛出的异常。

当目标 API 版本为 24 或更高版本时，您需要使用 内容提供程序 来与另一个应用共享文件。

英文:

The exception raised is

  1. android.os.FileUriExposedException: file:///storage/emulated/0/Android/data/app.xxxx.appimage/files/PicturesShared.jpg expobeyond app through ClipData.Item.getUri()

FileUriExposedException is caused by

> The exception that is thrown when an application exposes a file:// Uri
> to another app.

When targeting Api 24 or higher you need to use a content provider to share a file with another app.
