[Q] Unable to install apps from Play Store

Hello,
Post rooting (repenting it already) my Samsung Galaxy S Plus (GTI9001), I am unable to install any apps via Play Store. I am able to install apk's from the SD Card though. I un-rooted the phone but problem persist.
When I try to install any app, I can see the app being downloaded on the notification but the moment the download completes nothing happens. When i go to Play Store > My Apps I could see that it still says downloading though the app is fully downloaded. I guess some permission issues here. Please help.
I have already cleared Play Store cache and tried.

Hello,
Which Rom do you use? Maybe you have to root it again. Usually you can fix permissions in CWM. Have you tried to restart after "Download is finished". For Me it was working on my Asus EeePad.

Chris, I am still on stock ROM and I am not likely to go for a custom ROM since there are not much good ROM's available for Samsung Galaxy S Plus and Yes I tried multiple reboots. After reboot, on the notification it says that app download failed due to some error with a number.
Thanks for your reply.

Same issue
Reyolin,
I have had the same problem on my Samsung Galaxy S Plus but it has only started today. Mine has been rooted for about 5 months now, since I first got it.
I did a search using EStrong File explorer and it found a file called "downloadfile.apk" in /cache (I assume this is the file as it is the same file size as stated in the Play store. However, when I tried to run or copy it it had disappeared.
It's almost like the APK is being downloaded and then being deleted before installation actually occurs.
I think rooting your phone and the inability to install apps is just coincidental.
I will do some more playing about and see what I can find (I also already tried removing the Google Play updates (to go back to the old style Market). This still did not solve the problem.

Exactly same proble
Hi,
I have exaclty the same problem (galaxy s plus), rooted 5 month ago and problem started 2 days ago...
I updated superuser at that time and tried to update the su binarie but it fails on validation of new su and stopped (not replacing old su), this is the only thing I can remember of. root is still working with old su. Maybe the cleaning needs to be done ?
Has someone found a way to fix this?
edit:
after some investigation, this is what happens:
if I try to install one app from play store, it is downloaded correctly and then nothing happens.
the file downloaded is in /cache/downloadfile.apk
If I copy this file to /sdcard/external_sd/downloadfile.apk and run it manually it installs correctly.

galaxy s plus specific issue
i am having the same problem since morning and i also use Samsung galaxy s plus, so certainly the issue is phone specific.

Good news! Problem solved for me
Hi,
I contacted google play support and her was there answer:
Thanks for contacting us and I am sorry for the delay in responding.
We've gotten some reports that users with Samsung Galaxy S Plus devices running Android OS version 2.3 (Gingerbread) are having trouble using Google Play. We're aware of this issue and to solve it we recommend you to uninstall updates to the Google Play app by following these steps:
1. Tap Menu > Settings > Applications > Manage applications
2. Find the "All" tab
3. Scroll down to Play Store and tap to select
4. Tap "Uninstall updates"
Thank you in advance for your patience and understanding.
So I followed this and it works again!
Here are the steps after doing google recommendations:
- click google play icon, it will open old google market
- install an application, for me it worked again!
- exit google market
- click again the google play icon, it will ask to accept google play license
- click yes and then try to install another app, it worked again!
Hope this will solve also your issues,
Stef

I Just had the same problem. Here is how I fixed it,
- Uninstalled updates for Google Play
- I added a New Google Account.
- I Then signed into the new Google Account, Then Sign Into Your Main Account
And "BOOM" problem solved.

[Resolved] Play Store: Unknown error "-24" on installation

Hi there,
I had trouble installing Threema on CM yesterday and as I finally managed to get it running I wanted to share my insights.
When trying to install Threema, I received an unknown error "-24" from the Play Store. I searched this forum and found the advice to stop the Play Store app and to uninstall all updates. I did so, restarted the phone and received another error during install. This time it was "No sufficient memory". Well, on my clear Nexus 5 it was obvious that this can't be true. So I searched this forum again and found the advice to search for all files on my phone belonging to Threema. I used Root Explorer for this task and found a bunch of files all over the file system. I deleted them, stopped the Play Store app, uninstalled the updates, restarted the phone and finally was able to install Threema.
Hope this help someone else in misery, too.

[Completed] How can can I re-install android OS on my tablet?

My Lenovo tablet A 2701 A-H is literally not working anymore.
The problem started with:
1- Google play store gave me an error message saying "no connection" so I went on seeking all the methods that can solve the problem but nothing worked, it went on for so long and I kept trying with no avail.
2- I decided I should just delete the store and re-download it externally (an APK from the internet) which should work just fine , so since my device is rooted I uninstalled it with App Master and did what I wanted to.
3- The apk for the store that I downloaded just didn't work , It kept crashing and when it DOES open , it crashes if i try to download or update an app.
4- I just went to use another app store ( 1Mobile market) which installs apps just fine and they're up to date and everything, I thought my problem was solved but most apps don't work or the games without the google play store apparently.
5- I keep getting messages like " google play services error" or "an app can't open because google play services is not installed on my device" but IT IS, when I look in running apps and installed apps it IS THERE.
- NOW I'm thinking about re-installing the whole OS again, I'm not entirely sure if that can fix the problem also I don't know how I can do that, but I really need a solution , cause my Gmail app isn't working or youtube and I can't download games anymore since it requests to have google play games installed but apparently it doesn't work if I don't download it SPECIFICALLY from the google play store itself.
Note: My tablet runs android 4.0.3 ICS
Any help would be very much appreciated.

Sorry for this late response.

"Unknown sources" missing on Oreo

Hi, since the Oreo update I can't find the "Unknown sources" to install APK's freely. I'ts not under "Lock Screen and Security", and I have enabled Chrome in "Applications/Special Access/Install other apps" and I'm trying to install apps from the "Downloads" section of chrome, but it dosn't work this way either.
I was trying to install the Pixel Launcher as seen from here: https://theunlockr.com/2018/03/13/make-samsung-galaxy-s9-look-like-stock-android/
But everytime I try it I get the "<!> Application not installed".
I don't know exactly what says in english, I'm using my phone in spanish.
Any ideas? Thanks!

If you go to Settings-Apps-3 Dots-Special Access-Install Unknown Apps.
They've moved it so only certain apps can install unknown apps

Please help how to fix this problem. This doesn't work, I tried installing Accuweather pro several times. I have the app saved to my Google Drive, I click on the app and I see something called 'Staging App' and then I get this alert ' There was a problem parsing the package'. I currently had an older version of Accuweather pro installed and working fine. I decided to remove the old version and then reinstall it and I received the same alert. FYI the old Accuweather app was installed before the Oreo update.

Have you tried downloading your APP file from Google Drive to your phone then opening the copy on your phone, that should install the .apk

Go to settings on the phone >> apps >> 3 vertical dots at the top right corner >> special access >> install unknown apps >> and there enable the permission from where you are trying to download it.

All thank you,
I found out that you now have to download the app to your phone. Google Drive does not allow you to download and manually install .

Dear sir/madam,
Following your answer, in specific this part, "They've moved it so only certain apps can install unknown apps", perhaps someone could help me out. I use the Firefox Focus browser and this app doesn't show up in the list of apps that are allowed to install unknown apps.
* Does this mean Firefox Focus can't install apps from unknown apps, since it's not on the list?
* And perhaps we can conclude from that it will never be allowed to do so?
* Or would this app not be on this list, because I've never tried installing anything using this browser?
I guess the real question would be, what populates this list?
I hope to hear from you, thanks in advance, all the best.

Form what I've seen, 1st time you try to install apk from an app it asks you if you want to allow it?

That's what I was thinking as well, funny thing is that 'Google Chrome' is in the list and I've never used that browser. Unless it's there, because it's from Google

I have followed the above suggestions and have allowed Chrome to install apps since that's the browser I'm using. The phone says I have downloaded the app but it is not giving me any option to install it? Where did the download go and how can I get it actually installed? This is an app for work.
Edit: Nevermind - I restarted the phone and tried again and it worked. thanks.

google play services has stopped working, and the phone too

Hello
I have a Samsung A8 (2018)
It started to appear the message "google play services has stopped working"
I searched online and it says to go and delete cache and data, uninstall updates, but it's impossible.
The phone continue crashing every few seconds and it go back in the main screen.
In Safe mode it's the same thing.
I deleted the cache from bootloader but nothing change.
What can I do to save data and not just reset phone from bootloader?
Thank you

Just an Idea : Connect the Phone to PC -> Put another Version of the "Google Play Services.apk" on your Phone and try to rush there from Filemanager on your A8 and try to install over the faulty Version (maybe this could work)

I tried, but I can't.
After a lot of tries I could go in filemager but installation failed.
I tried also from safe mode

Does the Installation fails because of different signature ? maybe try with (For Example) APK Mirror installer ?

I don't know. It just take a lot of time and then says "app not installed".
I will try with APK Mirror installer, if I will be able to install it...
EDIT
I was able to install "APK Mirror installer". but same. I can't install "Google Play Services" because it says the version installed is newer.
Actually is the same version (the last one, downloaded from another phone with apk extractor)
