I am just starting to use Mono for Android Development environment. I use MonoDevelop as the IDE. I run one very basic HelloAndroid example and it is doing fine. Then I go ahead and run another bluetooth program in Chapter 8/BlueToothAdapter project.
The code is downloaded from the following link: http://www.wrox.com/WileyCDA/WroxTitle/Professional-Android-Programming-with-Mono-for-Android-and-NET-C-.productCd-1118026438,descCd-DOWNLOAD.html When I run it it goes all the way through "Deployment Completed" and then throws the exception below, on the emulator if I double click the app name "bluetooth" it just shows up for a couple seconds and then disappears and returns to the menu. UNHANDLED EXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object at BlueTooth.Activity1.OnCreate (Android.OS.Bundle) <0x00114> at Android.App.Activity.n_OnCreate_Landroid_os_Bundle_ (intptr,intptr,intptr) <0x00057> at (wrapper dynamic-method) object.d8c72470-48ef-4e40-8fd4-26e1cca19c00 (intptr,intptr,intptr)<0x00033> Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object at BlueTooth.Activity1.OnCreate (Android.OS.Bundle bundle) [0x00000] in <filename unknown>:0 at Android.App.Activity.n_OnCreate_Landroid_os_Bundle_ (IntPtr jnienv, IntPtr native__this, IntPtr native_savedInstanceState) [0x00000] in <filename unknown>:0 at (wrapper dynamic-method) object:d8c72470-48ef-4e40-8fd4-26e1cca19c00 (intptr,intptr,intptr) I am sure I did not change anything in the sample code so I really don't know what might possibly go wrong. Is there any project/linker configuration step that I missed? Anything specific to this program needs to be configured but not necessary for other simple program like HelloWorld? Any input can be very helpful!
