[Q] deleting apks is equal to uninstalling the appz?

Hi
Don't know as much about the Android OS compared to windows (and I do not have google playstore (marketplace) on my tablet
Is deleting an apk = to uninstalling the application. (Yes I have access to /system/bin as my device is rooted) or is it more like the apk is the executable while the executed program is some place(s) else like it is in windows OS
What are the other ways of uninstalling an android app ( I know one is clicking the apk already in the download folder)
Thanks

Its best to just uninstall it, then you will get rid of its data etc.
I'm sure there are plenty of uninstall apps, I use ROM Toolbox.
Sent from my LG-VS980 using XDA Premium 4 mobile app

No it wont uninstall the app when u delete its apk,
when u completely uninstall a app it will delete its data but since u dont have a google play store the apk will stay,
so whenever u want to install it again execute the game .apk but ofcourse u wont able to get ur last game data or atleast u have a backup of it.
U can install a third party app that uninstall app and system app but i know there's other way to uninstall a app without installing uninstaller app but it can only uninstall a app that youve downloaded but not the system apps. just search on how to uninstall an app depends on ur phone or tablet.

Rootetd Galaxy S7 not working with gear VR

Hi guys,
I rooted my Galaxy S7 and tripped KNOX. Today i recieved my Gear VR, Plugged it in, followed the inbstroctions to plug it out pressed next and.. error. The S6 from my brother works without a problem loads and installs everything... Can i flash the gear vr apps and software manually, or can i get the wizard back to work normally?

I'm using a rooted S7 with the VR with no problem.

All what I did is just plugging in the phone then I installed the app suing the VR itself.

I know when iam trying this i get the error "netzfehler" in german how did you root? and did you scale your dpi?

No I did not change dpi .. maybe this is the reason ?
I rooted by installing TWRP then wiping data ( this is to get rid out the boot looping issue ) then flashed SuperSU.
an by the way, I'm using 930F version

May be you can consider flashing back the Stock ROM and have your VR installed first then do the rooting again.

No idea how or why apn is checked smartphone resetet but still no internet and i don´t even know why...
Dos anyone of you kinow where i can download a stock kernel?
Edit: Found it internet works, but vr service still won´t start :´(

Well i am all out of ideas...
i installed the apps of my brothers s6 but no luck... everytime i plug the s7 out of the gear vr and press next the same error pops up... maybe if someone could spare vr services backed up via titanium backup it would work... for anything else i guess i have to wait for a software update or fix or whatever.

same pb here ! it was working ok before i rooted & Xposed it after a full reset.
i was not able to reinstall it because of internet error

Somehow i am glad to hear that i am not the only one with that Problem.
Did you play around with the dpi?

I read another thread on Oculus community forum... this issue occurred before even on other phones...
some says it could be coming from Oculus servers.
I tried to logcat the app ID 10072 that tried to read the DNS before displaying the network error.
also tried...
to fully reset the device
to run the app with/without Sim card,
with a VPN
deleting cache...
no luck so far

I read that the Facebook app has to be installed or enabled can someone confirm this ? and try to log in and launch the setup wizard ?
if don't have a Facebook account.

No, you only need com.facebook.appmanager and com.facebook.system services. Not the Facebook app itself.

I see both but i don't know what to do or what to trigger... another dead end
edit:
How do I turn on App Manager and Installer ?
To turn on the App Manager and Installer, tap on the "Settings" application, then "Applications" and finally "Application manager". Make sure you have chosen the "All" category and find the following applications:
com.facebook.appmanager (App Manager)
com.facebook.system (Installer)
Tap into each and make sure they are enabled.
Unable to find com.facebook.system
If you are on Android OS 6.0 (Marshmallow), com.facebook.system may not be visible. Please try the following steps:
1. Navigate to Settings
2. Tap on Application Manager
3. Tap the More menu in the upper right corner
4. Tap Show System Apps
5. This will make com.facebook.system visible and allow you to enable it.
The App Manager and the Installer must be enabled before Gear VR apps can be installed and updated on your mobile phone.

Settings app stopping again and again.

Hi everyone.
Running stock OP6 latest update.
Installed settings app from apk mirror and now the same won't open up instead keeps stopping again and again.
Since it won't open I can't uninstall it.
Anyone has a clue what to do about it?
Thanks in advance.
Edit. Same happening with dialer and contacts app.
Both updated through apk mirror.
Although Camera, Gallery and Files app work perfectly fine.
Anyone with an answer?
How to revert back to previous app version?
Edit : Finally had to reset my device and things settled. Although all my data is gone.
I suppose just too bad for me.
But I'm facing a pesky issue.
The files app shows no data but my gallery is picking up old garbage even after wiping the device clean. (Foolish of me not backing up the data)
PS I used the hard reset if anyone's wondering using the device's stock recovery.
I'll share the screenshot of the same..
Kindly suggest what's wrong with this..

i think u can uninstall app from the app drawer. long press the settings icon , and click uninstall if the options is available. if it isn't , u can re flash the whole rom by dirty flashing it. it shouldn't wipe the data.

As Azhar_Fahry mentioned, you can uninstall an app / app update from app drawer.
1. Tap and hold to get the options
2 (if OP launcer is updated), drag the icon to top (from app drawer) and you can select app info and then uninstall updates.
Alternatively,
You can install Link2SD and uninstall app / app updates from there.

Again system apps can't be uninstalled normally.
Secondly I'm not rooted to used link2SD.
I think need to dirty flash my phone.

System apps cannot be uninstalled if not rooted, but you can uninstall updates installed from play store or any external source. (You can reset the system app(s) to Rom default)
Attaching Scrrenshots - Follow from 1-end, click OK at the end. ( I am showing example of gmail, you can use it for any other systrm app too)
Naming screenshots 1-2-3-4-5 according to steps.

Uninstall updates to the settings app maybe. But if not dirty flashing the ROM will work

Cannot uninstall an app which I downloaded from Playstore.!

Cannot uninstall an app that I downloaded from Playstore
I tried to uninstall the app
1. Using playstore
2. Third-party apps
3. Via adb
it'll show that the app is uninstalled but no.. I cannot install new version of the app / apk.
Please see the reference video. Thank you

Scan with Malwarebytes.
Scan app file with online Virus total if you can.
Bad uninstalls don't happen as much on Android as Windows but all it takes is one to screw up the system.
SD Maid might be able to clean it up.
This is a great app for unrooted phones.
If you can't sort it... it will be reload time.

[root] Playing around and accidentally uninstalled the play store - how to undo?

So, this is my first time rooting a phone, and once I managed to get it to work, I started playing around to see what capabilities I had now.
In doing this, I uninstalled the play store. I've tried multiple methods to reinstall it, but none have worked so far.
I've tried installing a new play store apk and used systemize to turn it into a system app, but that didn't work (the app crashed on launch)
I've also tried using link2sd but the app wouldn't let me convert to system app.
If anyone else has any tips for me I'd be grateful.

Copy it from another device using ApkExport then transfer the installable copy over to the victim device and install.
I haven't tried it with Playstore but it works on other apks even if the donor device is on a different Android OS version.

sadly the only other device i have is a samsung galaxy S2 that is barely functional. I doubt that'll work.

Before you do anything I'd make sure you have a good backup of your device. Copy text messages, contacts, photos, etc all to external storage.
My first thought was just download install APK, but I see you've done that.
Someone else may have a better suggestion, but, if nothing else works, I'd try installing pico GApps to restore Playstore functionality.

Pico Package​This package is designed for users who want the absolute minimum GApps installation available. In this package you will find the core Google System Base, Google Android Shared Library, Google Play Store, Google Calendar Sync, Dialer Framework and the following Play Store applications:

Try it. It will copied system apks and updates.
I copied apks from a S4 running on Kitkat to my Note 10+. If it loads Playstore will need to update, that may be a problem... or not.

Google Play Store app by type is a normal 3rd-party app. Wondering why you want to convert it to a system app?

Yeah it's a system app on my Note 10+, can't be uninstalled*.
Normally it doesn't crash although it's common for it to not connect to Playstore. It does that if Google play Services is disable but even then it doesn't crash.
* I think, it has a disable option but to find out if there's an uninstall I would need to revert to the factory load first... which isn't something I want. It appears to be as I originally stated.

there is no uninstall option. I uninstalled it through other means as my phone is rooted. Now I'm having issues re-installing it and getting it to work.

My last 2 cents here:
Per definition only apps that are needed by Android OS to work are called system apps and are stored in /system/apps. Other apps - called 3rd-party apps like Google Play Store - may be stored in /system/priv-apps.
BTW:
If you manually install Google Play Store APK then it installs to /data/app directory - as expected.
