Can anyone propose a solution for this? screenshot of the problem

Answer 1

I'm having the same issue on my Emulator and device and also use the Fast Deployment but still sometime see the issue.

So far, my fix is either clean solution and build then deploy, that sometime will work. Or, restart my pc, that's also sometime works.

I don't have a solution yet, but with combine these two and try many time, it will work.

Answer 2

I'm using VS Community 2017, fix it by selecting Use shared runtime that it's not selected by default.

When I want install Visual Studio 2017, I remove Visual Studio 2015 first then install Visual Studio 2017 and have a same problem even in emulator, to resolve this problem, I uninstall Visual Studio 2017, then removed Xamarin and Android SDK, NDK completely from my computer, then install Visual Studio 2017 again and my problem resolved.

Answer 4

Actually, it seem to be a bug with Xamarin. I don't know since wich version this bug occur, but i have the same problem since i have updated to the last Builds.

This bug is occuring with my Amazon Kindle Fire. After some test, it seem that this is not really zipalign that is buggy, but the process of attaching to the Device that hang/fail afterward.

In order to be able to debug my Android platform, the only workaround i have found at the moment is to debug via an Emulator. I have used Android_Accelerated_x86 (Android 6.0 - API 23) Emulator that is shipped with the last versions of SDK.

I don't know if this Emulator is Xamarin related or from the Android SDK, but you can find it in the list of debuggable devices in Visual Studio when on Android platform as startup project.

I can deploy on this Emulator and debug on it. At least we can work and debug till this bug is fixed somehow.

Good luck!

For those experiencing this on an emulator, if you restart your emulator with the "Wipe User Data" option this issue goes away.

Answer 6

This question may be old but I had this problem right now.
I am using a real device and not an emulator and my solution was to:

1. Restart Visual Studio
2. Clean and rebuild the project
3. Restart the device

Then the deployment worked. I hope this is going to help someone.
