Enabling ProGuard puts application in infinite deploy loop #1646

Closed JonDouglas closed 6 years ago

JonDouglas commented 6 years ago

Steps to Reproduce

  1. Download the following repos & ensure you're in a Release configuration when deploying. App16-ProGuard.zip App16-NoProGuard.zip
  2. NoProGuard works as expected and deploys fine.
  3. ProGuard sits in an infinte deployment loop with details below regarding the ProGuard Task and adb logcat:

Note: This log is repeated indefinitely and sits in a deploy.

Expected Behavior

Application should run and deploy.

Actual Behavior

ProGuard is stripping types and in turn throwing an exception which is being infinitely retried. Application shows blank content and sits in a deploy phase.

MSBuild Log File

@JonDouglas : Does this happen with Xamarin.Android 8.3.0 (current stable)?

Does this happen if you build from the command line (msbuild /t:Install) or only via the IDE?

The MSBuild Log File provided shows no installation errors, nor a hang, but it does contain EnableProguard=true, which suggest it's a log file from when ProGuard is enabled.

I updated to Xamarin.Forms 3.2 in the attached project and it works after using this proguard.cfg:

-keep class android.support.v7.widget.** { *; }
-dontwarn android.support.v7.widget.*

As for the looping thing, I suspect there "used to be" some retry logic in the IDE when a deploy failed? I didn't see that loop behavior in VS 15.8.5.

I think we can close this as fixed now. There is an existing issue for adding default proguard config for Xamarin.Forms: https://github.com/xamarin/Xamarin.Forms/issues/2709
