I’m using a Samsung Galaxy Tab. OS is updated to the latest version. However, I’m unable to install the app from the Google play store. It downloads correctly, but then I get the error in the screenshot.
Things I’ve tried:
Any ideas?
Thanks in advance
Hello! Welcome back to our forum!
Unfortunately, this is beyond the scope of our application. This error message comes from the Play Store, not from us. Your device specifications look fine, so that should not be an issue!
Perhaps it was just temporary. What happens if you try it again now? Perhaps even on a different internet connection?
Kind Regards,
Malte
Hello, thanks for the reply.
It has been happening for a good 2-3 weeks now, probably more. I wanted to install the new version of charts and it started happening.
it only happens with Navigraph for some reason and I don’t know how to even figure out the nature of the issue
You mention that you have cleared the cache. What steps did you take to do this?
And did you click the link in that error message and follow their instructions?
I assume you followed these instructions?
Here’s a thread of someone else seeing a similar issue:
Kind Regards,

yeah I cleared the cache via
Settings → App → Google Play Store → Storage → Clear Cache
and did the same for Google Play Services
I also clicked the link in the error message, which isn’t really helpful (check your connection, update to the latest OS Version, etc.)
I’ve sent a feedback via that link, but I’d be surprised if they got back to me at all 
I’ll see if I can look at the system logs.
Thanks for your help
Ok I managed to dig a bit deeper. This is the issue:
App not installed as package conflicts with an existing package.
I was among the beta testers a couple of years ago, I wonder if that might’ve left some libraries around?
I’m not an android developer, so I’m not sure if it’s possible to clean it up without a factory reset?
Aha! That sounds like a possible reason for sure, but then you should not have been able to install any update since that beta?
Check your installed apps, see if you can find anything related to Navigraph and uninstall it!
That is what sounds really strange. However I’m sure I’ve updated it in the past, after removing the beta. And I’m also sure there isn’t any “Navigraph” installed at the minute.
I shall dig deeper - perhaps there are some spurious packages which haven’t been removed correctly.
That is weird indeed! We do not manually add files anywhere, the app itself is self-contained. If uninstalled, there should not be any unusual traces left on your device!
The closest error I have seen is when installing a new application version without changing its internal “build version”, which the Play Store uses to determine the app version. In that case, you get a similar (but not identical) error when installing it. Such a scenario is impossible for you to get in since the Play Store enforces correct versioning on their side before a release is possible.
There seem to be many resources on debugging this error out there online, including detailed steps on how to use ADB to do this on a system level. I wish you the best of luck in tracking this down! In case you need it, the bundle identifier of our app is com.navigraph.chartsrn.
ok… here’s an update from me. Had to go in debug mode 
but the actual error was
“Can’t install because provider name com.navigraph.chartsrn.blobs (in package com.navigraph.chartsrn) is already used by com.chartsrn”
Not sure what this com.chartsrn was, perhaps some spurious package left over by the beta? no idea. Anyway, I’ve removed it via terminal, and now it works
Thank you so much for sharing your solution! That is indeed a weird scenario to end up in and we’re happy to hear that you managed to resolve it.
Enjoy the new update!
