Description Jonathan Pryor 2013-05-28 14:19:10 UTC
Build and deploy can be slow because the $(MonoAndroidResDirIntermediate)\values\styles.xml (e.g. obj\Debug\res\values\styles.xml) is always updated, prompting a "rebuild cascade" as everything that depends on Android resources must be rebuilt.

Removing all calls to this: "_AddTrialSplashScreenResources" seems to fix this problem
Comment 2 Jonathan Pryor 2013-05-28 14:23:57 UTC
Can also be worked around by applying the following patch to Xamarin.Android.Common.targets:

diff --git a/tools/msbuild/Xamarin.Android.Common.targets b/tools/msbuild/Xamarin.Android.Common.targets
