Slow app build - Xamarin for Visual Studio -
the build/deploy of xamarin.android app painfully slow these days. cannot remember being slow before.
i have enabled:
- use shared runtime
- fast deployment
enabling or disabling these settings doesn't make difference. in both scenarios takes 2 minutes , 20 seconds (up on 3 minutes!) build/deploy app. using real device or visual studio emulator android doesn’t make difference well.
why extremely slow? not using right settings?
update 2
yesterday (november 14th) updated xamarin.vs 4.2.1.58. no improvements in build duration.
we using teamcity build release versions of our app, teamcity statistics show i'm talking about.
in graph below, selected last quarter date range. see major increase in build duration. now, don't mind waiting 3 minutes release build, it's not acceptable when debugging.
update 3
jon, help.
in meantime, have done research myself in build logs , found duration per build task well. found somehow getadditionalresourcesfromassemblies takes lot of time.
the amount of resources have in app didn't change dramatically, got me thinking: assembly i'm using..
i did checkout of revision 1029 (which last revision took minute build) , tried debug in updated environment. still built within 1m30s...
so:
- it's not vs xamarin update (else revision 1029 build slow well)
- it's not fast deployment, duration increased in build process
so changed between revision 1029 , 1030 of app?
- updated xamarin visual studio 4.2.0.719
- installed android 7.0 sdk platform in android sdk manager
- changed
compile using android versionandroid 7.0 in project properties - updated xamarin.android support libraries 23.4.0.1 24.2.1
change 4 why updated in first place, wanted use bottomsheet, improved in version 24. support library nugets targeting android 7.0, had 1-3 in order able update support libraries.
could have changed in support library bindings caused this? checked internet other devs having issue, , found this in xamarin forum. setting androidexplicitcrunch build property true seems fix there, when tried that, got build error.
anyway, that's i've tried in meantime. now, requested, here diagnostic build log:

thanks in advance!
although "tough" question answer build times can dependent on many different factors, can walk through ways determine what in build causing delay. in cases it's typically because of non-optimized resources. can resources raw images/audio/video should optimized mobile.
as experimental functionality mentioned, can view release notes here:
note: experimental, not guarantee stable enough use in production.
as build times, need know bottleneck within project. this, need enable diagnostic build output in build-agent's command. pretty simple msbuild via:
/v:diag or /verbosity:diagnostic (or whatever combination wanted)
and
/clp:performancesummary - tell use performance timings of each task

on. guess aapt, that's because android studio hang here tooling inside android sdk , responsible packaging android assets.
edit:
it looks build took ~2 minutes build 2 projects. 1 being in c:\development\apps\trunk\app.droid\app.droid.serviceclient\app.droid.serviceclient.csproj , other in c:\development\apps\trunk\app.droid\app.droid\app.droid.csproj (40 / 87 seconds respectively). seems quite normal project many third party dependencies android support / google play. can search string task "getadditionalresourcesfromassemblies show 6 places defined. there 2 tasks being invoked here due 2 android projects.
it might worth comparison of android studio project many external dependencies , compare time. know have quite bit of on-going work regards getadditionalresourcesfromassemblies task. work won't available until cycle 9-10. work apart of pull request:
https://github.com/xamarin/xamarin-android/pull/296
(you can tell it's brand new due commit time).
as can tell task, there following improvements:
the current task downloads data google. regardless of whether files exist in android sdk directory already. commit changes getadditionalresourcesfromassemblies task in "extras" folder in android sdk required .aar file. mean if user has date sdk, there no need download files internet.
there's pr - https://github.com/xamarin/xamarin-android/pull/292 (thanks @mikhail)
which addresses reusing computed hash can lower build times.
tldr; getadditionalresourcesfromassemblies needs bit more work build times shorter. in works.
edit 2:
this resolved in support libraries include dependency https://www.nuget.org/packages/xamarin.build.download/
