I just renamed the package and it worked for me.

Or if you are using Ionic, you could delete the application and try again, this happens when ionic detects that the app you are deploying is not coming from the same build. It often happen when you change from pc.

blocks|key|2525157|text|问题是为什么他会得到这个错误。卸载可以解决这个问题，但在我的例子中，当我安装apk的编译版本时，这个问题就出现了。我正在尝试为我的应用程序构建一个更新。所以我做了什么，我构建了一个签名的apk，然后尝试安装apk，并且apk安装得很完美。因此，与其删除旧的apk，我不得不签署新的更新，然后安装它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2525158|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The question was why he's getting this error. Uninstalling will solve this problem but in my case, while I was installing the compiled version of the apk, the problem raised. I was trying to build an update for my application. So what I did, I built a signed apk and then tried to install the apk and the apk installed perfectly. So, rather removing the old apk, I had to sign the newer update and then installed it.

blocks|key|47543|text|这可能是因为您的设备中有多个用户，并且您刚刚删除了其中一个上的应用程序(，将apk保留给其他(S))。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|47544|我已经删除了所有的账号，然后它就起作用了。|47545|entityMap^0|10|D|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

This maybe because you have more than one user in your device and you've just deleted the app on one (leaving the apk still present for the other(s)).

I've deleted in all accounts, and it worked afterwards.

This can happen if you sign your application with a different certificate. You can always use

<pre><code>adb install -r myapk.apk
</code></pre>

to overwrite an existing apk on your device, but you will still get the error if you signed the new apk with a different certificate that of the installed apk.

In that scenario you would need to uninstall the apk from your device before attempting an install. However, this can also impact your application since your original signing may be tied to certain Developor API's, so you may need to update the console with your new credentials.

In my case there was no version of the App I could find through device manager or Astro. 

What I ended up doing was:

1) Download the latest version of the App from the app store

2) The app was still not visible in device manager until I restarted my device.

3) Remove the app from device manager

4) Run my project again 

5) Everything works

It happened to me when I installed a dev build using Instant Run, and uninstalled from Google Play. For some reason the data from Instant Run is still in the device and can't install/uninstall the app again.

Only way to fix it:
- disable Instant Run in android studio
- install from android studio (it should work only from here)
- uninstall app

now it should be clean to install from Google Play or adb.

its occurred if you build your apk from some other PC and update it from different PC.

I don't see anyone mentioning my case so let me add it - it happens when you build the app in one mode (e.g. Dev) and then try to override it with a different mode (e.g. Production). 

The solution is the same as for the other cases - delete the app on the device/simulator and run again.

If you are attempting to debug from a different computer than you were originally you will get the dreaded INSTALL_FAILED_UPDATE_INCOMPATIBLE error. However, there is a way to proceed without uninstalling the app and losing your data.

To see how to transfer the debug.keystore that is required so you don't get the message "The device already has an application with the same application but a different signature. In order to proceed you will have to uninstall the existing application." (and lose your data). See <a href="https://stackoverflow.com/questions/18266947/update-the-app-in-another-machine-with-same-debug-keystore-in-android">Update the app in another machine with same debug.keystore in android</a>

You have to sign your application and then run it!
If you are preparing a new update for your application, it is not a problem to continue working. In the end, before releasing the prepared version, when you sign the application, the problem will be solved and users will have no problem installing your application.

<h2>WORK PROFILE / WORKSPACE</h2>
<a href="https://i.stack.imgur.com/ggBql.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ggBql.png" alt="enter image description here" /></a>
Don't forget that, depending on which user account you have on your phone (like a Google Workspace -G Suite Account profile with Device Management set to advanced) may generate a Workprofile to your phone.
90% of people have it but don't even know it. You normally see the Workprofile on the All app view. Is litterally like a separate workspace with separate Apps.
You can recognize when you are browsing app from Workprofile if they have a little lock of luggage.
Anyway :
<h2>You must delete the App from the Workprofile As well!!!</h2>

I've compiled Trebuchet launcher from CyanogenMod 9, and trying to install it with adb:

<pre><code>$ adb install out/target/product/generic/system/app/Trebuchet.apk
3986 KB/s (7870141 bytes in 1.928s)
 pkg: /data/local/tmp/Trebuchet.apk
Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]
</code></pre>

I tried on Nexus S with CM9 and Galaxy Nexus with stock JB. Why I'm getting this error?

EDIT: In my case I've tried to reinstall system package with package manager. That's not supported, so I've got this error. Source of the error may differ in your case.
