在Android(Java)中,如何打印完整的堆栈跟踪记录?如果我的应用程序因nullPointerException或其他原因而崩溃,它将打印出(几乎)完整的堆栈跟踪,如下所示:
java.io.IOException: Attempted read from closed stream.

但是有时出于调试目的,我想记录代码中的完整堆栈跟踪。我想我可以做到这一点:
StackTraceElement trace = new Exception().getStackTrace();
Log.d("myapp", trace.toString());
但这只是打印出指向对象的指针...我是否必须遍历所有堆栈跟踪元素才能将其打印出来?还是有一种简单的方法可以全部打印出来?
