quickstart-android: How to get crashlytics stacktraces deobfuscated

Step 1: Describe your environment

Android device: Any
Android OS version: Any
Google Play Services version: 4.2.0
Firebase/Play Services SDK version: 17.0.0

Step 2: Describe the problem:

Ever since Google introduced R8 I’m not getting my crashes stacktraces in crashlytics deobfuscated. I used to get them before, but not anymore, have the configuration described in this page. What should I do to get my crashlytics crashes report deobfuscated, the Stack Traces from Google Play are deobfuscated.

Relevant Code:

proguard-rules.pro

-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception
-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**

We were struggling with this issue as well - thought bumping to 1.30+ would be the solution (per https://github.com/firebase/firebase-android-sdk/issues/745). What we ended up finding was that we were losing the deobfuscation only when distributing the apk through Firebase, and only when doing so via the appDistributionUploadRelease gradle command. (Manual APK uploads to Firebase were fine). In our case, we were running ./gradlew appDistributionUploadRelease after running ./gradlew assembleRelease both on their own. We realized the appDistributionUploadRelease task didn’t call crashlyticsUploadDeobsRelease, and thus realized we should have been calling ./gradlew assembleRelease appDistributionUploadRelease as a single command. (As the docs state, sheesh!) Hopefully that will help someone some headache in the future (or help y’all potentially repro the issue 😃 )

I get the same problem with io.fabric.tools:gradle:1.31.2. Logs show that Deobfuscation file(s) uploaded, but stack traces in Crashlytics are obfuscated, for example b.a.a.a.s0.m.j1.l.

@GuanacoDevs had the same issue after updating to ‘io.fabric.tools:gradle:1.31.0’ crash reports are deobfuscated properly

Updating to io.fabric.tools:gradle:1.31.0 did not work, still can’t get the stack traces deobfuscated, this is really painful. What am I missing here?
