要在Kotlin中打印CallStack,可以使用Throwable.getStackTrace()方法并使用println()函数打印堆栈跟踪。这是一个例子:
fun main() {
try {
divide(10, 0)
} catch (e: Exception) {
e.printStackTrace()
}
}
fun divide(a: Int, b: Int): Int {
return a / b
}
在这个例子中,我们调用divide()函数并传入两个参数:10和0,这将导致ArithmeticException。因此,我们捕获异常并使用e.printStackTrace()方法打印堆栈跟踪。输出将类似于以下内容:
java.lang.ArithmeticException: / by zero
at MainKt.divide(Main.kt:10)
at MainKt.main(Main.kt:4)
这显示了异常的调用堆栈,从异常本身开始,回溯到导致异常的原始方法调用。

To print the CallStack in Kotlin, you can use the Throwable.getStackTrace() method and print the stack trace using the println() function. Here is an example:
fun main() {
try {
divide(10, 0)
} catch (e: Exception) {
e.printStackTrace()
}
}
fun divide(a: Int, b: Int): Int {
return a / b
}
In this example, we are calling the divide() function with two arguments: 10 and 0, which will lead to an ArithmeticException. So we are catching the exception and printing the stack trace using the e.printStackTrace() method. The output will look something like this:
java.lang.ArithmeticException: / by zero
at MainKt.divide(Main.kt:10)
at MainKt.main(Main.kt:4)
This shows the call stack for the exception, starting with the exception itself and going back to the original method call that caused the exception.

"Lod.d(TAG, "Stack: ${Log.getStackTraceString(Throwable())}")" 可以翻译为 "Lod.d(TAG, "堆栈: ${Log.getStackTraceString(Throwable())}")"。
英文:
Lod.d(TAG, "Stack: ${Log.getStackTraceString(Throwable())}")
