Xamarin.Android 4.6.3


Known issue: Immediately after upgrading, users may have trouble loading Xamarin.Android projects. Please restart Xamarin Studio again if you experience this.

Visual Studio Users: You should be prompted with this update when you open a Mono for Android project. You can also check manually in Tools > Options > Mono for Android.

MonoDevelop Users: You should be prompted to upgrade next time you open MonoDevelop, or you can use Help > Check for Updates. IDE support requires Xamarin Studio 4.0. Layout Designer fixes require MonoDevelop 3.0.4.

Bug fixes

  • Fixes a Linker error which occurrs when building a Release build of a project which references Mono.Android.Support.V4.dll .
  • 5037 : Support satellite assemblies.
    Note : Deploying Debug+Fast Deployment builds which use satellite assemblies will require an updated Xamarin Studio to deploy the satellite assemblies. Using Release builds, disabling fast deployment, using Visual Studio, and command-line msbuild / xbuild use will properly deploy satellite assemblies.
  • 9572 : adb logcat is spammed during fast deployment process.
  • 10840 : Fast deployment option makes deployment slow...


  • 9433 : Reverted as this fix was indirectly responsible for an ArgumentOutOfRangeException when linking a Release app which references Mono.Android.Support.v4.dll .


Warning: Samsung shipped a broken kernel with Android 2.1, which is not able to support JIT compilation. If you possess a Galaxy-class device with Android 2.1, you will get unexpected results, this is caused by a kernel bug that breaks cache coherency, rendering any engine doing JIT compilation useless. Check with your manufacturer/carrier for an Android 2.2 update.
