Hi, I'm having a problem with subclassing AsyncTask<>. I think this may be related to a known Mono for Android bug.
I have a class that subclasses AsyncTask<> and implements RunInBackground() and OnPostExecute(). This compiles and deploys, but a release build fails at run time (on emulator or real device). Logcat gives me the following: E/mono ( 1446): Unhandled Exception: System.ArgumentException: Couldn't bind to method 'GetDoInBackground_arrayLjava_lang_Object_Handler'. E/mono ( 1446): at System.Delegate.GetCandidateMethod (System.Type type, System.Type target, System.String method, BindingFlags bflags, Boolean ignoreCase, Boolean throwOnBindFailure) [0x00000] in <filename unknown>:0 E/mono ( 1446): at System.Delegate.CreateDelegate (System.Type type, System.Type target, System.String method, Boolean ignoreCase, Boolean throwOnBindFailu re) [0x00000] in <filename unknown>:0 E/mono ( 1446): at System.Delegate.CreateDelegate (System.Type type, System.Type target, System.String method) [0x00000] in <filename unknown>:0 E/mono ( 1446): at Android.Runtime.JNIEnv.RegisterJniNatives (IntPtr typeName_ptr, Int32 typeName_len, IntPtr jniClass, IntPtr methods_ptr, Int32 methods_l en) [0x00000] in <filename unknown>:0 E/mono ( 1446): at (wrapper delegate-invoke) <Module>:invoke_intptr__this___intptr_intptr_string_string (intptr,intptr,string,string) E/mono ( 1446): at Android.Runtime.JNIEnv.GetMethodID (IntPtr kls, System.String name, System.St D/Zygote ( 33): Process 1446 exited cleanly (1) This looks like a known bug filed at https://bugzilla.novell.com/show_bug.cgi?id=690048 and also (later?) at https://bugzilla.xamarin.com/show_bug.cgi?id=1945. This seems to have come out of discussion at http://mono-for-android.1047100.n5.nabble.com/another-Java-versus-C-how-to-td4332736.html involving Jonathan Pryor. I'm confused because the bug on the xamarin bugzilla is marked as RESOLVED FIXED, but I'm seeing it in monodroid 4.0.4 (win7/vs2010), which seems to be the latest version. Is this fixed, or am I seeing a regression or just doing something wrong? Any workaround?
