I am using Visual Studio 2012 and Xamarin.Android Beta release to develop an Android application. When I try to deploy the android application for debugging purposes onto an Android device, it deploys the previously built application on the device and not the recent changes I made and deployed (i.e No refresh of build). However, if I use Xamarin Studio to do the same, it deploys the correct build everytime (i.e refreshes the build with new code changes).

Any idea why this is happening?

Thanks in advance!

I had a similar issue: With Visual Studio 2019 the debug version of my driver was deployed while building the release version.

The cause of my problem was, that in the Properties -> Driver Install -> Package Files I had an absolute path pointing to the debug version of my driver in the column File. This setting is valid for all configurations (not separated for debug/release), and when entering macros, they are immediately expanded to absolute paths.

I fixed this by editing the .vcxproj file with my favourite editor and changed the path back to $(TargetPath).

I have no idea why it does this, I had this issue before. I also noticed that the device log was somewhat behind (ie, at 3.30pm, the last record on the device log was 11.00am).

Uninstalling the app from the device and re-deploying it seems to correct it.

Note: I had this issue in VS, didn't check with XS.

I would look at the difference in your deployment settings in VS and XS (I think it may have something to do with the Fast Deployment option).

  • I am only having this issue with VS. It doesnt seem to uninstall the previous version of the application on the device. Thanks for your input! I will check it out and get back to you! – Aniket Sharma Jun 25 '13 at 13:04

I had the same problem. My solution was to add "deploy" to the build configuration:

BUILD => Configuration Manager... => (select "Debug" from left-hand combo-box) => (tick "Deploy" in grid)

Similar question (though for iOS Simulator) here.

I had a similar problem (though on an Android emulator).

What didn't work for me:

  • restarting the computer
  • restarting Visual Studio
  • deleting bin / obj folders
  • going into Configuration Manager (Debug / Release / Configuration Manager) and ticking everything there - everything was ticked
  • changing the version of the app in the manifest

What worked for me?

Uninstalling the app from the emulator and then running Debug again. It was an Android emulator, so I uninstalled by clicking on the app icon and holidng for long, and then dragging it to "Uninstall App". On an iOS simulator it should be similar.
