For newer devices you will encounter FileUriExposedException. Here is how to avoid it in Kotlin.

val file = File(Environment.getExternalStorageDirectory(), "this")
val authority = context.packageName + ".provider"
val uri = FileProvider.getUriForFile(context, authority, file)
val emailIntent = createEmailIntent(uri)
startActivity(Intent.createChooser(emailIntent, "Send email..."))

private fun createEmailIntent(attachmentUri: Uri): Intent {
    val emailIntent = Intent(Intent.ACTION_SEND)
    emailIntent.type = "vnd.android.cursor.dir/email"
    val to = arrayOf("some@email.com")
    emailIntent.putExtra(Intent.EXTRA_EMAIL, to)
    emailIntent.putExtra(Intent.EXTRA_STREAM, attachmentUri)
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "subject")
    return emailIntent
}
