'Build and Deploy' to Android device suddenly fails

[MoriartyX64]

Suddenly, as of today, I am unable to 'Build and Deploy' to my Android device. I'm using the AppBuilder Visual Studio extension, version 2014.2.806.3. This worked perfectly earlier this week, up until last tuesday, but now I'm constantly getting errors on Android only.

Some facts:

* No mentionable changes (like project properties, plugins and such), except for changes in the html
* Simulator works fine
* Only fails on Android; Deployment to iPhones works perfectly
* Deployment worked before (tuesday was last succesful deploy to the Android)
* Build and Deploy in cloud fails as well (error: "Cannot find application package for Android. See the log for more information.")
* Device is found in the devices list

I have already tried the following, without success:

* Restarted Visual Studio and the system
* Rebooted the Android device + killed all running applications
* Reconnected the device, building in the cloud, build and publish locally
* Clearing the cache: %localappdata%\Telerik\BlackDragon\Cache

Build output:

Any suggestions are more than welcome...

Update: I have absolutely no idea what caused this suddenly. But it appears I'm not the only one with this issue, see also:
http://stackoverflow.com/search?q=INSTALL_FAILED_UID_CHANGED

There seem to be three possible fixes for this:

1. Change the application name, e.g. identifier. This was no option for me.
2. If you have root access to the Android device you can try to find some remaining clutter that blocks a deploy. 
3. Reset the device (to factory settings)

The last option worked and therefor the issue is resolved for me. Hope this helps other as well.

Hello MoriartyX64,

Thank you for contacting us about this issue. It appears to be a common matter for Android applications, as from the link you have provided. I am glad you have found a solution that works for you.

Further, you can also check if uninstalling the app manually from the device and deleting all its data folders solves the issue. This is explained in more details here.

As a token of gratitude for sharing the solution with our community, I have updated your Telerik points. Please, let us know if there is anything else, we can help you with.

Regards,
