Proguard does not remove logical calls

Question

When compiling my application with Ant, I can see the detailed output of Proguard, and I have settings for deleting log statements (see below), but when I run release apk, all the log statements that I tried to delete are there.

I have 2 projects, each of which includes a common project. In the two main projects and in the general project, each has a proguard.cfg file, all of which contain a fragment for deleting log statements.

Is there something I am missing?

** All my log statements are Log.d (...)

proguard.cfg

Answer 1

Here your proguard file is fine, but there are details that may be missing.

In your gradle file, you have something like this:

 buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt), 'proguard-rules.pro' } } 

Check getDefaultProguardFile('proguard-android') , so if you intend to optimize it, you should change it to getDefaultProguardFile('proguard-android-optimize.txt') .

I took some time to figure this out, saw your question, but still could not delete my Log calls of my code. So I found this link that explains that it is necessary to change file optimization so that proguard can optimize.

Answer 2

You cannot use assumenosideeffects without optimizing Proguard.

Answer 3

Instead of deleting or commenting on all of your log messages using pro-guard, you can do something like this. Create a utility class, which basically is the shell of the Android registration system.

 public class Util{ public static boolean showLogs = true; public static String myTag = 'My Tag'; public static void logD(String message){ if (Util.showLogs) Log.d(myTag, message); } } 

Until I compile my application for distribution, I just call showLogs = true; and then all log messages are suppressed

You can easily extend this class so you can specify a tag and create more than debugging messages.
