如何编写控制台消息?

问题描述

Android.我用过:

Android. I used:

import android.util.*;
......
Log.d("MyActivity", "Debug output");

但这不会在控制台中显示任何内容.我还可以使用什么呢?

but this not show anything in console. What else may I use?

推荐答案

System.out.println("Debug output");

[修改]
我在SO上找到了这一点，它在一个解决方案中表示，将Android System.out和System.err中的重定向到/dev/null，有效地将所有输出发送到了必杀技.请阅读有关SO的详细信息:是否可以在Android应用程序中打印到控制台? [ ^ ]

还有一个很有希望的链接会将您发送到此网站: http://developer.android.com/tools/help/adb.html#logcat [^ ]

[Modification]
I found this bit on SO where it says in one solution that in android System.out and System.err are redirected to /dev/null, effectively sending all your output into nirvana. Please read the details on SO: Is there a way to print to the console in an Android app?[^]

There is also an promising link sending you to this site: http://developer.android.com/tools/help/adb.html#logcat[^]
