I am currently developing an android application and it was always working like a charm.
But yesterday I wanted to manually remove the application from my phone via uninstall. The uninstall dialog popped up, run through and closed again but the application was still there.
I tried it several time, also restarted my phone but I still could not delete the application.
After some time the dialog said "cannot uninstall system application".
My application is a standard android application which does not have to do anything with a system application at all.
I was searching for answers but could not find anything helpful.
So do you guys have any suggestions?
(My Phone is not rooted)
So I found out what the problem was.
Somehow eclipse installed the application for every user on the smartphone.
With Lolipop you have the possiblity to have several users and switch between them.
So the only thing I did is I selected "uninstall for all users" and the application was removed.
You can find the option in the installed apps list.
Sorry for the question turned out to be a quite stupid one.

I'm using Android Studio 3.5 and can't install an app from it.
My app is already on play store and I'm upgrading the app.
It keeps saying there's a same application.
Okay, so I deleted it, but it keeps saying that.
First a pop-up window saying that I will have to uninstall the existing application. I know why it happens. I develop on my laptop and my desktop at the same time so it happens all the time. And this app doesn't have my data so I've clicked okay and proceeded and there was no problem. But,
The device already has an application with the same package but a different signature.
Retry
The application could not be installed: INSTALL_FAILED_UPDATE_INCOMPATIBLE
in new. And even I don't have the app, why does it say like that???
And installation is way too quick on play store.
I think the app isn't deleted properly.
So basically, I have no app on the phone, the data, cache, apk, anything, but it keeps saying there is a same app with a different signature.
I have
Deleted the existing app and it still didn't work
Re-downloaded the app and ran and didn't work
And as expected, it says if I wanna delete it, pushed OK. And the app is
automatically deleted.
also adb uninstall com.~~.~~ not working
Set debuggable true, still not working
Ran on a friend's phone which already has the exact same app from the store
and it works.
Tried to disable instant run but android studio 3.5 does not have that anymore.
Rebooted my phone.
Deleted caches of android studio and restarted it, as many as I could.
adb shell pm list packages -f : the package does not exist.
done adb uninstall com.~~.~~ and got Success code, but still not working
There's nothing wrong with codes.
Build works perfect. It runs perfectly on my friend's phone.
I expect for the app to run perfectly but,
the studio says
The device already has an application with the same package but a different signature.
Retry
The application could not be installed: INSTALL_FAILED_UPDATE_INCOMPATIBLE
Also, installation is too slow. It wasn't slow like this.
this happen when you have multiple spaces or user in single phone, it will be helpful if you can tell about your phone model
So i'm gonna be as elaborative as much as I could..
I have a Xperia L with latest firmware and I was trying to set some third party apps to system apps, and I succeeded after some time I thought that if I could set App updates to system app (meaning removing the older version) and I succeeded again but when I was doing the same to Chrome I stumbled upon to a problem..
So before I tell you what was the problem i'll tell you how I did it..
1.I updated Chrome.
2.I moved the original. apk from "system/app" dir to My SD so that it can be changed to new one. (My set is ROOTED)
3.Then I moved the. apk from "Data/app" folder to "system/app" folder.
4.And renamed it to the Original. apk 's name.
5. And changed the Read/Write Permissions as it should be.
6.That's that.
So after that I tried launching chrome but it said
"Chrome failed to start due to an Unexpected Error"
but with above methods I replaced a lot of apps like Walkman, Calendar, PlayStore, Play Services and some i don't remember...
and they all worked fine even after restarting it..
so then I uninstalled Chrome with Titanium Backup since it was a system app..
and then I tried the same with Album app.
I replaced it's. apk and tried it but it started crashing.. so I deleted it. too and placed the original one back..
and restarted my set..
But now it is stuck on Black Screen after Sony logo...
I know I can Flash the ROM to get going but if there's any other way to do so please let me know..
now i know it's kinda two questions in one but I really need to know both..
Thanks in advance...
You can use Link2SD or other root apps to add them automatically to the system image
Does anybody has the Idea of making an android app undeletable.I want to install selected apps on the system memory so that anyone having an access to my phone cannot delete those apps even after resetting the phone...
What I earlier saw was that the apps installed on the system memory cannot be changed or modified by ordinary users...I tried resetting my phone but saw some apps preinstalled from the company remained and all the apps that were downloaded from the play store were deleted..
The answer I got from searching the web was that I could make install an Android app to the system memory...does it make the app undeletable even after resetting or formatting the phone?
You can achieve this by making your application by Developing a Device Administration Application, follow this link http://developer.android.com/guide/topics/admin/device-admin.html.
you could only do this if you root your phone and place the apps inside system/apps.
However, if this is about your phone, why don't you use a password protector for apps, so nobody can access the app manager?
Removing a users choice to uninstall your app, goes against everything most programmers strive for. It's probably against the Google T&Cs also. And as already said, other than Malware or some dodgy virus attempt, there would be no practical (ethical) use for such an app, IMO.
I've accepted for a while now that it's impossible to silently install an application on Android - that is, to have a program install an application bundled as an APK without providing the standard OS installation prompt and going through the app installer activity. But now I've picked up a copy of the Appbrain fast web installer, and it does exactly this.
How on earth is this possible? :D
I think the clue is pretty much in this statement I found here in the FAQ.
The fast web install worked for me yesterday, but it doesn't work anymore today. What's wrong?
The permission to install apps directly on your phone needs to be refreshed once every few days. Go back to the "Fast Web Install" app on your phone and click the button to give us the permission again. We are working on a future update that will optionally automatically refresh this setting.
I presume this is very similar to what Google does in the kill switch. I am assuming that the kill switch is an application on my device, just hidden from me. When Google wants to remove an application, it silently uninstalls it without asking for our permission. I am very sure this security hole is of their making. Now we just need to figure that out... =D
You can ( in a very hackish way ) install apps silently using adb. You have to enable USB Debugging, but just push the APK to /data/app. ie:
adb push MyApp.apk /data/app
or -
adb install MyApp.apk (cleaner way)
The second command MAY prompt for an installation, I don't remember off the top of my head.
IF you can work out what the standard installer does when it installs, you can replicate that behaviour in your app, however yours would need quite extensive permissions to do everything properly.
Seriously, don't even try.
I have some Android market feedback for my app Hire*A*Droid where users complain that they are unable to uninstall the application. Here's two I have so far (about 10 days apart):
janelle: I uninstalled this app, but its still showing that its
installed under my downloads. What can i do ?
valerie: It's frozen I can't open or delete it.
anyone can help n tell me how..thanks
The app has nothing really special or tricky about it and I never experienced anything of the sort so I'm really lost at what this may be, how real it is and how to reproduce and deal with it? Any ideas, suggestions? If you have any questions that you think may help with this problem I'll be happy to provide more details
P.S. Worth nothing to mention - both complaints cost me a single star rating and no additional info was provided
P.P.S. After comment from PHP Jedi I noticed similar comments for other apps while browsing Android Market. I think this is quite common and it looks like Market bug. I will try to open a bug on Android Market support site
Cross-referenced to Android Market forum
I purchased a DROID a week back and was having the same problem. To uninstall an application from the DROID do the following.
Uninstalling an application from Android OS v2.1
Go to settings.
Go to Applications
Go to Manage applications.
Touch the application you wish to uninstall.
Touch uninstall.
Enjoy the fact that the application is gone.
The confusion I'm guessing your commenter's are having is when you hold your finger on an application you can drag it to a trash bin. This makes you think you are deleting the application when really you are removing it from your favorite applications list. Its very misleading.
from what i understand (i don't work on Market myself), the "Downloads" list inside Market can be out of date for up to a day, until it next gets an update from the server. the app isn't actually installed anymore, and Settings > Applications > Manage Applications will show that it is indeed gone.
i reported this as a Market bug internally last year. i've just added a link to this page from that bug, and i'll try to get someone to look at it.
(it may even already be fixed in newer versions. it would be interesting to know the most recent version you've seen it in.)
I could not say why the users complain, but I could say that your application work without problem on my HTC Magic, I don't get error when I tried to uninstall it.
Best Regards
