Crashlytics doesn't deobfuscate code

Question

I have mysterious problem with Frabric(Crashlytics) service.
I found that crashlytics doesn't de-obfuscate crashlogs automatically.

io.fabric.tools version 1.19.1 and android.tools version 1.2.3 in top-level build file:

dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'
    classpath 'io.fabric.tools:gradle:1.19.1'
}

BuildTypes config:

buildTypes {
    debug{
        debuggable true
        jniDebuggable true
    }
    release {
        debuggable false
        jniDebuggable false
        minifyEnabled true
        proguardFiles 'proguard-coda.txt', 'proguard-rules.pro'
    }
}

And dependencies:

compile('com.crashlytics.sdk.android:crashlytics:2.4.0@aar') {
    transitive = true
}

The proguard config file contain:

-renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTable

From gradle console I see tasks related to crashlytics are okay :app:crashlyticsStoreDeobsRelease and :app:crashlyticsUploadDeobsRelease:

Executing tasks: [:app:assembleRelease]

Configuration on demand is an incubating feature.

:app:assembleRelease

BUILD SUCCESSFUL

Total time: 11.569 secs

But crash logs are still not de-obfuscated.

Caused by: java.lang.RuntimeException: Test exception!!!
       at coda.RootActivity.onCreate(SourceFile:189)     <====
       at android.app.Activity.performCreate(Activity.java:5990)
       at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1106)
       at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2278)

Can somebody help me with it?

Are you including the mappings.txt file. Look at this other question for some ideas: http://stackoverflow.com/questions/26875519/crashlytics-not-deobfusticating-code — moxi, Jul 22 '15 at 23:26

I checked one of our projects, we are not using this line in proguard configuration and it's working fine

-renamesourcefileattribute SourceFile
