Question

My boss hopes that there is no information leak when users use our android apps.
And I found even I set the android:debuggable="false" it still can see my logs from Logcat or command line.
I searched android:debuggable someone also have the same problem.
I got some answers from internet, such as next:

There are a property called debugable of Avd. You can print by adb
shell get prop. I don’t (know) if it is the cause of your problem.

If you have a pre-production device, you
can still debug an app that has debuggable set to false.

I just think, even I delete all my logs, there are also many logs about my app from OS.

My questions:
1.Is there a way I can do let my "android:debuggable" work well and
2.Is there any other way to hide all my logs except delete all my logs?
3.What does "android:debuggable" really mean?
4.What is "a pre-production device" when it goes on android device?

Thank you for your help. I will try some other ways, and try my best to share my information in here.

Answer 1

I simply create wrapper functions around Log that first check the value of a static boolean called loggineEnabled if it is set to true then log gets called otherwise the calls to log are ignored.

Then I simply set this variable to false before I compile a version of my app that I distribute.

void LogD(String msg){
   if (loggingEnabled)
       Log.d(MyTag, msg)
}
