Ub0rLogg0r

ub0r logg0r is just a simple wrapper around the android.util.Log class. It allows you to write things like Log.d(TAG, "foo=" + foo + ", bar=" + bar) as Log.d(TAG, "foo=%s, bar=%s", foo, bar) or Log.d(TAG, "foo=", bar, ", bar=", foo). This simple change allows you to remove Log.d() and Log.v() with with proguard WITH the strings you are passing to it.

Just add the following lines to your proguard configuration:

-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
}


-assumenosideeffects class de.ub0r.android.logg0r.Log {
    public static *** d(...);
    public static *** v(...);
}

Including in your project

Either include it in your project as an android library project, or grab it via maven:

<dependency>
    <groupId>de.ub0r.android.logg0r</groupId>
    <artifactId>logg0r</artifactId>
    <version>{latest.version}</version>
    <type>jar</type>
</dependency>

Or add it in your build.gradle

repositories {
    maven {
        url 'https://raw.githubusercontent.com/felixb/mvn-repo/master/'
    }
    mavenCentral()
}

dependencies {
    compile 'de.ub0r.android.logg0r:logg0r:+'
}

Migration

To migrate to this library you need to:

1. Change the imports from android.util.Log to de.ub0r.android.logg0r.Log
2. Use the new method parameters instead of concatenating strings in your app

A simple sed like this should do the work:

sed -e 's:android.util.Log:de.ub0r.android.logg0r.Log:g' -e '/Log.[dviwe](/s: *+:,:g' -i [your *.java files]
