Trying to build unity game for android device

Hi I am having real problems compiling/building my unity game to work on android device I keep getting most of the way through but then I get three errors
at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (BuildPlayerOptions options) [0x0020e] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:181
at UnityEditor.BuildPlayerWindow.CallBuildMethods (Boolean askForBuildLocation, BuildOptions defaultBuildOptions) [0x00065] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:88
UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()
Any help would be appreciated

UnityEditor.BuildPlayerWindow+BuildMethodException: when building Unity project for iOS - Stack Overflow that maybe?
