I am having issue debugging Android project. I can deploy to device and run it, all works fine but if I try to debug, the app gets deployed to the device and very briefly opened, splash screen shows up but the app then closes.

I am using Xamarin Forms on Visual Studio 2015.

Device is running Android Oreo (8.0.0). Another device running Android 6.0.1 is debugging fine.

The output shows following:

InspectorDebugSession(11): StateChange: Start -> EntryPointBreakpointRegistered
InspectorDebugSession(11): Constructed
Android application is debugging.
InspectorDebugSession(11): HandleTargetEvent: TargetExited
InspectorDebugSession(11): Disposed
Couldn't connect to logcat, GetProcessId returned: 0

I checked Logcat and it seem to be having issues finding FFImageLoading library:

I have added Nuget package for FFImageLoading to my projects and Droid project references show it as in image below:

This worked for me :-

Deselecting the 'Use Shared Runtime' in Project Properties > Android Options > Packaging properties

I also had this issue with Android 8.1 and Visual Studio 2017 15.7.4.

There are three steps to got it working again.

  1. Under Android Options, go to Advanced and add your device architecture, in my case it was x86_64.
  2. Go to Tools -> Options -> Xamarin > Android Settings and enable: Provide debug symbols for shared runtime and base class libraries.

  3. And the final step is to delete following Apps from your device:

    • All Xamarin.Android API Support libraries
    • Mono Shared Runtime
    • Your App

After these steps you don't need to disable "Use Shared Runtime" and can Deploy and Debug much faster.

  1. deselecting 'Use Shared Runtime' in Project Properties > Android Options

  3. clean solution
  4. rebuild the solution it works
