I'm creating an email intent and attaching a file (using a FileProvider) but the Gmail client reports "impossible to attach the file".
I had this working previously but it's now broken. I didn't change my code (that I'm aware of) but have updated both the OS and the Gmail client.
// Build email IntentUri mailToUri = Uri.fromParts("mailto", "", null);Intent emailIntent = new Intent(Intent.ACTION_SEND, mailToUri);emailIntent.setType("text/plain");emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);emailIntent.putExtra(Intent.EXTRA_SUBJECT, "A subject");emailIntent.putExtra(Intent.EXTRA_TEXT, "A body");// Build the attachment URIFile attachFile = new File(aDirectory, aFileName);Uri attachmentUri = FileProvider.getUriForFile(this, FILE_PROVIDER_AUTHORITY, attachFile);emailIntent.putExtra(Intent.EXTRA_STREAM, attachmentUri);// Start the share activitystartActivity(emailIntent);// Alternative methods for creating the URI // Uri attachmentUri = Uri.parse("file://"// + attachFile.getAbsolutePath());// Uri attachmentUri = Uri.parse("content://"// + FILE_PROVIDER_AUTHORITY// +"/"+ attachFileName)Gmail client presents the draft email with subject and body, but reports "impossible to attach the file".
I've also tried using the alternative methods shown for creating the Uri. The first used to work before FileProviders became mandatory. The second fails in the same way as the above code.
There are some Gmail error messages in the LOGCAT:
