Question

Why won't some pdf-files open on tablet/phone? [Android]

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.

    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.

      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.
