Steps to reproduce
1)Open Project QualityAssurance/Manual/CrossPlatformDebugging/CrossPlatformDebugging.sln
2) Open the project properties on Android.Debugging, uncheck to disable 'Bundle assemblies into native code'
3) Delete bin and obj folders from
   XamFormsTestApp.Data (PCL)
   XamFormsTestApp.Droid (App)
4) Set Breakpoint in PCLCustomerSample>Services in VesselService.cs file on line 38
5) Deploy to Android Device (Google Nexus 7)
6) Determine if breakpoint is hit on line 38
7) Stop debugging session
8) Delete bin and obj folders from
   XamFormsTestApp.Data (PCL)

I think problem is on XA side because doing `adb shell ls /storage/emulated/0/Android/data/com.companyname.android.debugging/files/.__override__/` shows that Portable .pdb is not copied... Disabling "Fast Assembly Deployment" fixed it for me... My wild guess is... problem is in https://github.com/xamarin/androidtools/blob/ff1b3d6f2351fa925b46289beb0efcd6b935299a/Xamarin.AndroidTools/Sessions/AndroidDeploySession.cs#L482
Comment 2 Jonathan Pryor 2017-04-10 15:26:46 UTC
@David: What XA version are you using? Is it d15-2/Xamarin.Android 7.3.0?

My current understanding is that Xamarin Studio uses/will use Xamarin.Android's `Install` target -- which brings it inline with Visual Studio, and reduces duplicate code (yay!) -- and thus that `AndroidDeploySession` is not the entire picture.

The `Install` target uses the `<InstallPackageAssemblies/>` task, which explicitly checks for `.pdb` files for installation:


Additionally, when I use monodroid/master's `Install` target, the `.pdb` file *is* installed:

> $ xbuild /t:Install /v:diag Android.Debugging.csproj
> $ adb shell ls -l /storage/emulated/0/Android/data/com.companyname.android.debugging/files/.__override__ | grep pdb
> -rw-rw---- 1 u0_a211 sdcard_rw   6872 2017-04-10 11:18 Android.Debugging.pdb
> -rw-rw---- 1 u0_a211 sdcard_rw   5436 2017-04-10 11:18 XamFormsTestApp.Data.pdb

This is also using system mono 4.9.3:

> $ mono --version
> Mono JIT compiler version 4.9.3 (2017-02/c52c4bd Mon Mar  6 18:14:39 EST 2017)

Note: I was *not* able to build+install Android.Debugging.csproj using Xamarin Studio 6.3 (build 858); it reported an error in the `<ResolveAssemblyReference/>` task.

Neither Peter Collins nor I am able to repro this issue.
Comment 4 Gaurav Ganorkar 2017-04-11 13:51:29 UTC
I am still able to reproduce this issue on the latest VSFM build (2770).

I am not able to hit the Breakpoint explicitly on last three cases mentioned on Android debugging project. Just to be explain it in details. under Android Debugging projects we have around 25 cases which need to be validated for breakpoints. Out of this 25 sample test cases the last three cases where failing for breakpoint.

Below is the github link for sample project consisting of fail 3 sample cases.

Note: On Previous XS build for MAC (i.e before 2710), above breakpoints were getting hit for the same github sample
Comment 5 Gaurav Ganorkar 2017-04-11 15:57:27 UTC
Cloning the repositories on to different path  fixed the issue. Hence marking this issue as Resolved fixed.
Comment 6 Peter Collins 2017-04-11 16:47:43 UTC
I'm going to update as NOT_REPRODUCIBLE I think, as that more accurately describes the investigation. The affected sample has been uploaded to slack, but I still was unable to manage a reproduction on both a Nexus 5x and Oneplus One.

Test case:

The only _potentially_ relevant differences in this test case were:
* Fastdev was disabled
* Shared runtime was disabled
* The Debug property group was missing an `AndroidSupportedAbis` declaration. However to my best of my knowledge the armeabi-v7a value will be used as a default in this case either way.
