61.1142.1 won't compile with proguard enabled

[jahmai-ca]

Xamarin.Android Version (eg: 6.0):

8.3.3.2

Operating System & Version (eg: Mac OSX 10.11):

Windows 10

Google Play Services Version (eg: 8.4.0):

61.1142.1

Describe your Issue:

Upgrading from 61.1142.0 to 61.1142.1 causes proguard failures relating to missing org.apache.http.legacy.jar.
Seems to relate to this commit: 000969c#diff-3c71accc87ca84e8d4d0855b0445ed30
Reverting to 61.1142.0 fixes the issue, or, put the following snippet at the bottom of your csproj:

  <Target Name="AddOrgApacheHttpLegacyJarInProguardExternalJavaLibs" DependsOnTargets="_ResolveMonoAndroidSdks;_ValidateAndroidPackageProperties" AfterTargets="_ResolveMonoAndroidSdks;_ValidateAndroidPackageProperties" BeforeTargets="Proguard" Condition="$(IncludeOrgApacheHttpLegacyJarInProguard) == 'True' and Exists ('$(AndroidSdkDirectory)/platforms/android-$(_AndroidTargetSdkVersion)/optional/org.apache.http.legacy.jar')">
    <ItemGroup>
      <AndroidExternalJavaLibrary Include="$(AndroidSdkDirectory)/platforms/android-$(_AndroidTargetSdkVersion)/optional/org.apache.http.legacy.jar" />
    </ItemGroup>
  </Target>

Steps to Reproduce (with link to sample solution if possible):

Update to 61.1142.1 and enable Proguard.

Include any relevant Exception Stack traces, build logs, adb logs:

Really you should just need this snippet as a work around for now:

<ItemGroup>
      <AndroidExternalJavaLibrary Include="$(AndroidSdkDirectory)/platforms/android-$(_AndroidTargetSdkVersion)/optional/org.apache.http.legacy.jar" />
</ItemGroup>

We're working on determining why this isn't being properly included for now.

Alternatively you can make your own proguard config file which has:

-dontwarn org.apache.http.**

[Redth]

We removed this as having both DependsOnTargets and AfterTargets was causing errors in some msbuild versions. It looks like we should have used AfterTargets instead as DependsOnTargets doesn't seem to get picked up.

[Redth]

Will be fixed in any future releases. Thanks!
