这是完美的例子
在Xamarin Android(C#)中看起来像这段代码

与我正在寻找的东西很相似

[Application] class UnhandledExceptionExampleApplication : Application,Application.IActivityLifecycleCallbacks { private Activity _CurrentActivity; public Activity CurrentActivity { get { return _CurrentActivity; } set { _CurrentActivity = value; } } public UnhandledExceptionExampleApplication(IntPtr handle,JniHandleOwnership transfer) : base(handle,transfer) { } public override void OnCreate() { base.OnCreate(); AndroidEnvironment.UnhandledExceptionRaiser += (sender,args) => { /* * When the UI Thread crashes this is the code that will be executed. There is no context at this point * and no way to recover from the exception. This is where you would capture the error and log it to a * file for example. You might be able to post to a web handler,I have not tried that. * * You can access the information about the exception in the args.Exception object. */ }; AppDomain.CurrentDomain.UnhandledException += (s,e) => { /* * When a background thread crashes this is the code that will be executed.

This can be used to keep track of the current Activity #region IActivityLifecycleCallbacks Members public void OnActivityCreated(Activity activity,Bundle savedInstanceState) { _CurrentActivity = activity; //throw new NotImplementedException(); } public void OnActivityDestroyed(Activity activity) { //throw new NotImplementedException(); } public void OnActivityPaused(Activity activity) { //throw new NotImplementedException(); } public void OnActivityResumed(Activity activity) { //throw new NotImplementedException(); } public void OnActivitySaveInstanceState(Activity activity,Bundle outState) { //throw new NotImplementedException(); } public void OnActivityStarted(Activity activity) { throw new NotImplementedException(); } public void OnActivityStopped(Activity activity) { throw new NotImplementedException(); } #endregion }
