Can not read PDF files in cloud using Kindle Fire HD 7 error: The document path is not valid

[rmgconsult]

I have been using my Kindle Fire HD 7 to read/edit PDF files in the Document Cloud for years with great pleasure and success.

However, I have a problem now. My files in the Document Cloud are fine. I can read them from my computer. However, when I go to my Kindle Fire HD 7 using the Adobe Reader app (which I have been using successfully for years) I can see a list of all of my files in the Document Cloud. But When I click on a file, it generates a sequence of negative numbers with lots of digits while it says "opening file x". Then it stops and reports the error message "The document path is not valid."

Initially this problem was just for my new files that I added to the cloud. So I uninstalled the app and reinstalled it.

Then I had the same problem for ALL of my Document Cloud files!!

Help!!!

I've seen this before in a desktop computer also.

Seems like the app was trying to find a file in a directory that is not there anymore, or, after an update of the operating system or the app itself the directory paths for certain programs might've changed.

Re-check that Adobe Acrobat mobile is the default pdf handler app and not an Internet browser, like Google Chrome, or any other pdf capable software that was installed.

If it is not the browser, find and delete the offending program.

If that does not work for you, please review Meenakshin's recommendation in the following thread:

Hi, I just wanted to say that I've been having the same problem from right around the same date until now. None of the suggestions that have been given so far seem to work.

The problem is not resolved. I really loved using Adobe Cloud before but
now I am not using it at all with my Kindle.

Hi,

I just noticed that in my prior reply the recommendation that I linked applied to iPads not Android. Please

look here: https://www.amazon.com/gp/help/customer/display.html?nodeId=200790620

Identify your product and operating system version from the link above and also update your operating system to reflect its current version.

Uninstall Adobe Acrobat Mobile App  completely; then go here: https://get.adobe.com/reader/enterprise/

Download and install the full offline installer for Reader DC from the link above and not from the Playstore. 

Be advised that FireOS is based on AndroidOS Nougat version 7.1 stable release 2. So you will probably have to try both the 32bit or 64 bit version from the link above for  AndroidOS versions 5 and above. If that download doesn't work in your device , try the Acrobat installer version  for Android  4.4.

On the other hand, I read recently from this thread:https://community.adobe.com/t5/acrobat-reader/acrobat-reader-for-kindle-fire/td-p/10520960 that Amazon has discontinued the use of the Google Playstore.

So maybe you're able to manually install the Adobe Acrobat Reader mobile app  version that can fit in your Kindle device.

But honestly, if my suggestion above doesn't work, when this situations happen to me, if I was in your shoes, I would unlock and root that device device and see if it works?

Even better, I would definitely install Android Nougat myself in that device or another custom made Android version with no bloatware, like BlissOS for example.

As you may already know rooting and unlocking is supported now in 5th generation tablets and above:.

Thank you very much! I was desperate having exactly the same problem. 

Question is: if I root my kindle fire will kindle reader work anyway, just like before? I'll try to ask it in the video thread too.

Rooting an Android mobile device, wether a phone or a tablet, is a way of obtaining administrative priviledges in your device.

Rooting per se does not affect any app, in any case, it gives you more control of what to remove and install. That said, you cannot root a device before it is unlocked.  The process is a little technical, which may require a little knowledge of linux in combination with some open source, freeware, or paid-for tools.

You root a device to be able to change the operating system for example, or even tweak performance settings that otherwise are hidden and locked by most device manufacturers, specifically with cell phones that you already own.

In the case of plans that involve offers like bring your own phone, the carrier service providers that control your bandwidth and data plans for your mobile device will lock this ability to root and unroot a device.

But to answer the real question, yes you should be able to download and install the Amazon Kindle app

See here:

And here:

https://getyeti.webflow.io/posts/how-to-install-the-google-playstore-in-your-amazon-fire-tablet 

The two links above are work arounds if rooting is not supported in your device amd if you don't wish to root a device.

However, my suggestion of rooting and installing your preferred AndroidOS version that can fit in that tablet is because you get complete access to the Google Playstore and just simpmy install the free Amazon Kindle app from there.

Sorry for my looong answer, but I hope you can find it somewhat useful.

[Maíra Matos]

No need to sorry, thanks a lot.

The question is that the Acrobat app is here in my app list, even though it doesn't apear in app store. I can still install it. So i don't think it will chage something just to focus on the google play store. I'll problably need to root it.

thanks!

You're welcome, I'm glad you were able to get additional insights.

Hey rmconsult, if you're still looking for a solution, I found one. I've also had the same problem with opening PDFs in Adobe Reader on my Kindle since November. Last night I decided to try to root it and switch OS as suggested by ls_rbls. In the process I found an easier solution than switching the entire system.

If follow the directions in the link, you can download a workable Adobe Reader from the Google Play store. (And get access to other Google Play Apps.)

I hope it helps!

Hi,

just checking if you were able to resolve your issue.

Just today I posted this thread for another user in hopes that it helps. 

I forgot to add, however, to  be aware that both methods offered in this thread, like rooting an Android device and/or   enabling "Apps from Unknown Sources" and "Android Debug Bridge (ADB)" gives access to all applications in your device which may compromise all of your data.

Make sure that you know what you're doing when using these advanced features.
