推荐答案

您需要研究使用Java进行标准IO. 有System.in System.out和System.err，请在这里阅读有关它们的信息: Java IO :System.in，System.out和System.err [

You need to look into doing standard IO with java.
There are System.in System.out and System.err please read about them here: Java IO: System.in, System.out, and System.err[^].

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? [ 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[^]
