I simply get the error saying: The document cannot be opened because it's not a valid pdf-document.
However I have no problems opening the file with my laptop, only my phone and tablet (Jellybean 4.2.2) won't open it.
My friends also have managed to open the file on their tablets (android/windows).
Have reinstalled and checked updates and tried other programs but none has worked for me.
I simply have no clue and would appreciate help.

PDF files created by some non-Adobe products aren't structurally correct. Adobe Reader and Acrobat products try their best to open even such PDF files but they do differ in terms of the kind of such pdf files they are able to open.
You mentioned that your friends are able to open up the same PDF file on their Android devices. Did they also use Adobe Reader? If so, would it be possible for you share that PDF file with us (romil@adobe.com)? That will allow us to do some investigations.
Thanks.

Hey,
spent some time discussing this with some friends of mine and found out
that the document can be opened by downloading it to the computer and
transferring then to the tablet or phone. The difference is that when
downloading with tablet/phone I get a .pdf file, which only has some html
code. So I guess the problem has something to do with the encryption of the
file. Here are the 2 different files I get as attachments. After all this
might not have anything to do with adobe, but some other stuff I don't
really understand.

Hey,
Seems like the problem was in the web browser I was using, as the file just
didn't download correctly.
Thanks for the help anyway, much appreciated.

When a browser like Chrome on Android gets a PDF link and offers you the ability to open the file in Acrobat it's only the URL that gets sent across to Acrobat, if the site you are loading the PDF from required a login to access the material when Acrobat requests the file, it may well be getting back a HTML login page instead of the PDF, which it can't render.
This is why if you download the file first and then open it in Acrobat it all works fine.

Experienced the same thing. The same file was emailed from my computer and from another. On my Android phone, one of them can be opened, the other cannot. The one that can't be opened can be downloaded but I still can't open it from file manager or download, ONLY through opening the Adobe Acrobat app and looking for the file can I open it.

Today I faced the same problem with a pdf file that has 14MB. What I did to open was use one web site to compress the file to 3MB and then I sent the email with the file attached. Now my android opened the file with adobe reader properly. The website that I use was Comprimir PDF – Comprimir arquivos PDF online
But you can search another site or app to do the job for you. So the advice is to ask to the person who sent the file always use files with a size limit when you have some fast work that needs to be checked by phone or some other device. Otherwise you can use your laptop or desktop to check the file.
