This Fall Lookout mobile discovered that developers were writing some pretting interesting things to LogCat and the talked about their findings at DefCon.
While, as a dev, you should try to never put sensitive information in your logs, you can use this system to turn off logging in your releases.
At the beginning of each of my classes i write:
Notice the DebugMode.MODE is a separate class, and it's a pretty simple one:
Anyways, then, when I want to put something in LogCat I write
Finally, when I'm ready to release, I only have to change the DebugMode class to:
And voila! We now have Both fine-grained per-class control of how much info gets sent to LogCat, as well as a Global on/off switch that will help keep prying eyes out of our logs.
Anyways, hope that helps

At the beginning of each of my classes i write:
Code:
public class MyClass
{
// Debugging
private static final String TAG = "MyClass";
private static final boolean GLOBAL_DEBUG = DebugMode.MODE;
private static final boolean LOCAL_DEBUG = true;
private static final boolean D = ( GLOBAL_DEBUG && LOCAL_DEBUG );
Code:
public class DebugMode
{
public static final boolean MODE = true;
}
Anyways, then, when I want to put something in LogCat I write
Code:
if (D) Log.d ( TAG, "something interesting happened");
Code:
public class DebugMode
{
public static final boolean MODE = false;
}
Anyways, hope that helps
