Kotlin全局捕捉协程异常方法详解

  val handler = CoroutineExceptionHandler { coroutineContext, throwable ->
            Log.d(TAG, "onCreate: handler${throwable}")
        }
        Log.d(TAG, "onCreate:1")
        findViewById<Button>(R.id.button).also {
            it.setOnClickListener {
                GlobalScope.launch(handler) {
                    Log.d(TAG, "onCreate: onClick")
                    "anc".substring(10)
                }
            }
        }
