Attaching image to email on Android creates "Unknown.dat"

mpappas · September 8, 2012, 9:59am

When I attach an image to an email on Android, it is renamed to “Unknown.dat”, which causes it to be unrecognized / not displayed by the recipient.

The image was created by taking a picture on the device, and using corona to create a jpg, which is then sent. Everything works great on iOS - but on Android, “Unknown.dat”.

Anyone able to get images sent correctly through email on the droid? [import]uid: 79933 topic_id: 30737 reply_id: 330737[/import]

I am trying to do the same on Nook, and getting a different error. If I attach an image to an email I get an error message in the email popup “File too large to attach”. The jpg image is small, something like 200x200 pixels. The email will send, but there is no image attached.

Same code works fine on an actual iPad. I can send images attached to email no problem.

Can anyone confirm they can send images through email via Nook, android, or Kindle? Or can CoronaLabs confirm this isn’t working correctly on Android?

I tried setting permissions for READ_ and WRITE_EXTERNAL_STORAGE but that didn’t fix it.

Hey Stephen,
Did you ever figure this one out? I have the same issue on Android.
Emailing pngs works on Google Mail but not on the standard Email client.

Same here deano. Haven’t been able to modify anything to affect the default android behavior. I haven’t tested specifically with jelly bean though - < sarc>but maybe someday soon android will recognize something as exotic as pngs or jpgs as email attachments…< /sarc> [import]uid: 79933 topic_id: 30737 reply_id: 134447[/import]

Funny you bring this up now. There’s another active thread where Joshua, the Coronalabs Android developer, is trying to get this working on Nook. See here:
http://developer.coronalabs.com/forum/2011/12/31/mail-android-attachment-not-ok

The latest daily build #978 introduces a fix that allows for email image attachment. With this build I finally had luck sending jpg attachments. There are a couple problems I’m having with the fix, and I don’t know if the fix affects things on the various flavors of Android, but if you haven’t tried it I would give the latest build a shot. Chime in with your results in the other thread since Joshua seems dedicated to getting this working. [import]uid: 9422 topic_id: 30737 reply_id: 134457[/import]

Thanks Stephen, I’ll try that latest build, I was on 971. [import]uid: 67683 topic_id: 30737 reply_id: 134461[/import]

mpappas,

The “Unknown.dat” issue is now fixed. We also fixed file attachment issues on the Nook as well. These fixes are available in the newest daily build.

The only known mail attachment issue left on Android (that we know of) is that file names containing spaces do not get sent via e-mail correctly. They cause garbage to show up at the bottom of the e-mail and the file does not get received. You can work-around this issue by removing the spaces from the file names.

Anyways, if you could let us know if this newest daily build solves this attachment problem for you too, then that would be great. Thanks! [import]uid: 32256 topic_id: 30737 reply_id: 134547[/import]

@Joshua,

Just tested on my android (ver 2.3.6) with build 978 using the default android mail client (same one I had problems with before), and now in the email client in the attachment area, it shows the image filename and extension, and underneath it says “Unsupported file type” ( it used to call the attachment “unknown.dat”, instead of showing the real filename)…

On completing/sending the email, it shows up properly on the receiving end. Not perfect (because of the “Unsupported File Type” message in the droid email client, but hey, maybe they just don’t support jpgs and pngs, dunno). Also on the receiving end, there’s nothing to indicate there was any problem, the mail (and attachment) looks great.

Thanks for the fix Joshua! [import]uid: 79933 topic_id: 30737 reply_id: 134553[/import]

I’m glad it’s working for you!

Regarding the “Unsupported File Type” issue, I wasn’t able to reproduce it on my 1st generation Droid. I tried the standard “Email” app and the “Gmail” app. Both of which displayed the file names correctly without any error. I’ve tried image files with extensions *.png, *.jpg, and *.jpeg; all of which worked. I’ve also tested it with a Kindle Fire mail app and the Nook app as well. The Kindle Fire shows nice thumbnail images of the attached image files.

So, can you offer me any clues on how to reproduce this issue on my end?
Are you sure the mail app you are using is the standard Email app or is it a 3rd party app?
Perhaps the Android log provides some clues?

I’m using pngs now, on a motorola atrix running 2.3.6. Other than that, nothing special, pretty basic (not many apps installed at all). It’s definitely the default email app I’m using (I also have gmail on the device, which has been fine with the attachments all along). So, not sure other than getting a stock atrix, or perhaps a motorola device of the same era (about 1.5 yrs old), how it’s easiest to reproduce it - it could be particular to that version of the android email client.

I just went into the app manager for the device, and went to the email app. It is listed as version 2.3.6 (which happens to be the same version of android installed), so I’m pretty sure it’s the default email client for that droid version.

As far as the log is concerned… Droid is pretty noisy… But here’s the log from just as the app calls to send the email, until shortly after the email app appears on screen (showing attachment, waiting for user to enter recipients name). My app /corona has handed off to the OS where the log says “Application Suspend *************” (it’s in my suspend handler)… At that point, it’s in android hands entirely (and the android mail app)… Didn’t see anything that jumped out at me, other than a few droid “parse error” things here and there, but I’ve seen those at other times as well me thinks…

But the state of sending with the default handler for 2.3.6 is ok by me… Could be it’s unique to 2.x, or 2.3.x, or even just 2.3.6 (the end game upgrade for my atrix, so I’m stuck/users stuck with the minor irritation of that little error message on the device - not too big a deal I think). I’d be interested to hear any results of your investigations, and thanks again for the fix for “unsupported.dat”.

Thanks for posting this information. The only interesting thing that I’m seeing in the log is this…
[lua]CursorWrapperInner: Cursor finalized without prior close()[/lua]

You see, mail apps do SQL like queries to the Corona app to essentially ask for more information about the files it is trying to attach. Information such as the file’s display name, file size, mime type, etc. We return that information via a Cursor object in Android, which contains rows; kind of like how it works with a database. This is how we solved the “Unknown.dat” issue… and on Nook, responding to these queries was required to get file attachments to work.

I’m not sure if the above log message is the reason for the error that you are seeing, because the mail app clearly succeeded in fetching all other information from the Cursor. But it’s definitely something for us to investigate. Nothing on Android is ever easy. *sigh*

In any case, thanks again for investigating this on your end. [import]uid: 32256 topic_id: 30737 reply_id: 134663[/import]

Hey Stephen,
Did you ever figure this one out? I have the same issue on Android.
Emailing pngs works on Google Mail but not on the standard Email client.

Same here deano. Haven’t been able to modify anything to affect the default android behavior. I haven’t tested specifically with jelly bean though - < sarc>but maybe someday soon android will recognize something as exotic as pngs or jpgs as email attachments…< /sarc> [import]uid: 79933 topic_id: 30737 reply_id: 134447[/import]

Funny you bring this up now. There’s another active thread where Joshua, the Coronalabs Android developer, is trying to get this working on Nook. See here:
http://developer.coronalabs.com/forum/2011/12/31/mail-android-attachment-not-ok

The latest daily build #978 introduces a fix that allows for email image attachment. With this build I finally had luck sending jpg attachments. There are a couple problems I’m having with the fix, and I don’t know if the fix affects things on the various flavors of Android, but if you haven’t tried it I would give the latest build a shot. Chime in with your results in the other thread since Joshua seems dedicated to getting this working. [import]uid: 9422 topic_id: 30737 reply_id: 134457[/import]

Thanks Stephen, I’ll try that latest build, I was on 971. [import]uid: 67683 topic_id: 30737 reply_id: 134461[/import]

Joshua_Quick · December 10, 2012, 3:26pm

mpappas,

The “Unknown.dat” issue is now fixed. We also fixed file attachment issues on the Nook as well. These fixes are available in the newest daily build.

The only known mail attachment issue left on Android (that we know of) is that file names containing spaces do not get sent via e-mail correctly. They cause garbage to show up at the bottom of the e-mail and the file does not get received. You can work-around this issue by removing the spaces from the file names.

Anyways, if you could let us know if this newest daily build solves this attachment problem for you too, then that would be great. Thanks! [import]uid: 32256 topic_id: 30737 reply_id: 134547[/import]

mpappas · December 10, 2012, 4:46pm

@Joshua,

Just tested on my android (ver 2.3.6) with build 978 using the default android mail client (same one I had problems with before), and now in the email client in the attachment area, it shows the image filename and extension, and underneath it says “Unsupported file type” ( it used to call the attachment “unknown.dat”, instead of showing the real filename)…

On completing/sending the email, it shows up properly on the receiving end. Not perfect (because of the “Unsupported File Type” message in the droid email client, but hey, maybe they just don’t support jpgs and pngs, dunno). Also on the receiving end, there’s nothing to indicate there was any problem, the mail (and attachment) looks great.

Thanks for the fix Joshua! [import]uid: 79933 topic_id: 30737 reply_id: 134553[/import]

Joshua_Quick · December 10, 2012, 8:10pm

I’m glad it’s working for you!

Regarding the “Unsupported File Type” issue, I wasn’t able to reproduce it on my 1st generation Droid. I tried the standard “Email” app and the “Gmail” app. Both of which displayed the file names correctly without any error. I’ve tried image files with extensions *.png, *.jpg, and *.jpeg; all of which worked. I’ve also tested it with a Kindle Fire mail app and the Nook app as well. The Kindle Fire shows nice thumbnail images of the attached image files.

So, can you offer me any clues on how to reproduce this issue on my end?
Are you sure the mail app you are using is the standard Email app or is it a 3rd party app?
Perhaps the Android log provides some clues?
