Crash with ProGuard and Firebase Crashlytics

由 冷暖自知 提交于 2020-04-16 05:20:21

问题


Expected

It is expected for the release version of the Android app's build to run successfully when enabling minifyEnabled and shrinkResources per the Android documentation, Crashlytics, and Proguard.

The code for this issue may be found in the open-sourced GitHub repository for Coinverse.

Observed

  • The release version of the app crashes immediately when opened after being downloaded from Google Play. This appears to be due to Crashlytics failing to initialize.

  • Without minifyEnabled and shrinkResources the app runs as expected in production, and the app size goes from ~4mb to ~10mb.

  • The error log suggests it is an issue with Firebase compatibility and recommends this StackOverflow post. - What ProGuard configuration do I need for Firebase on Android?

  • There is a similar issue with ProGuard - transformClassesAndResourcesWithProguardForRelease FAILED.

App.kt

The release version of the app is crashing when attempting to initialize the FirebaseHelper.kt class.

class App : Application() {
    val component = DaggerComponent.builder()
            .utilsModule(UtilsModule(this))
            .build()

    override fun onCreate() {
        super.onCreate()
        // Here is where the crash occurs.
        component.firebaseHelper()
        MoPub.initializeSdk(this, SdkConfiguration.Builder(AD_UNIT_ID).build(), initSdkListener())
    }

    private fun initSdkListener() = SdkInitializationListener { /* MoPub SDK initialized.*/ }
}

FirebaseHelper.kt

@Singleton
class FirebaseHelper @Inject constructor(context: Context) {
    private val LOG_TAG = FirebaseHelper::class.java.simpleName

    init {
        if (BuildConfig.BUILD_TYPE == open.name) {
            var openSharedStatus = false
            FirebaseApp.getApps(context).map { app ->
                if (app.name.equals(open.name))
                    openSharedStatus = true
            }
            if (!openSharedStatus)
                FirebaseApp.initializeApp(
                        context,
                        FirebaseOptions.Builder()
                                .setApplicationId(APP_ID_OPEN_SHARED)
                                .setApiKey(APP_API_KEY_OPEN_SHARED)
                                .setDatabaseUrl(DATABASE_URL_OPEN_SHARED)
                                .setProjectId(PROJECT_ID_OPEN_SHARED)
                                .setStorageBucket(STORAGE_BUCKET_OPEN_SHARED)
                                .build(),
                        open.name)
        }
        Firebase.setAndroidContext(context)
        initializeRemoteConfig()
    }

    private fun initializeRemoteConfig() {
        val firebaseRemoteConfig = FirebaseRemoteConfig.getInstance()
        firebaseRemoteConfig.setConfigSettingsAsync(FirebaseRemoteConfigSettings.Builder().build())
        firebaseRemoteConfig.setDefaultsAsync(R.xml.remote_config_defaults)
        val cacheExpiration = 3600L
        try {
            firebaseRemoteConfig.fetch(cacheExpiration)
            firebaseRemoteConfig.fetchAndActivate()
        } catch (exception: FirebaseRemoteConfigException) {
            Crashlytics.log(Log.ERROR, LOG_TAG, "initializeRemoteConfig: ${exception.localizedMessage}")
        }
    }
}

Attempted Solutions

1 - Explicitly enabling Crashlytics in build.gradle

buildTypes {
    release {
        ext.enableCrashlytics = true
        ...
    }
    ...
}

2 - Adding proguard.cfg rules for Firebase.

-keep class com.firebase.** { *; }
-keep class org.apache.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.w3c.dom.**
-dontwarn org.joda.time.**
-dontwarn org.shaded.apache.**
-dontwarn org.ietf.jgss.**

# Only necessary if you downloaded the SDK jar directly instead of from maven.
-keep class com.shaded.fasterxml.jackson.** { *; }

3 - Adding proguard.cfg rules for the app model classes being returned and posted to Firestore's database.

# Add this global rule
-keepattributes Signature

-keepclassmembers class app.coinverse.analytics.models.** {
  *;
}
-keepclassmembers class app.coinverse.feed.models.** {
  *;
}
-keepclassmembers class app.coinverse.priceGraph.models.** {
  *;
}
-keepclassmembers class app.coinverse.user.models.** {
  *;
}
-keepclassmembers class app.coinverse.utils.** {
  *;
}

4 - Adding pro-guard-rules-release.txt

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules-release.txt'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules-test.txt'
