Google Firebase - how to delete Crash reports?

I know this is old, but now there is a way to disable Crashlytics when in debug mode.

In your app level build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
//...

    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            manifestPlaceholders = [crashlyticsEnabled: true]
        }
        debug {
            manifestPlaceholders = [crashlyticsEnabled: false]
        }
    }
}

//...

And in your AndroidManifest.xml inside application tag:

<meta-data
    android:name="firebase_crashlytics_collection_enabled"
    android:value="${crashlyticsEnabled}" />

The best thing you can do for the long term is to create two different instances of the app, one for debug/dev and another for release, and make sure they have different package names. This should allow you to view them each independently in the console. You can configure this pretty easily in your build.gradle.

This topic was also discussed in more detail on our firebase-talk group, but from the perspective of Firebase Analytics. Be sure to click through to get more details on how the gradle build works.

As far as actually deleting the issues that come up, there's not currently a way to do that, but we are looking into that for a future release. We definitely hear everyone's feedback on that.

It has the option to Close the issue in the GUI. I have attached the screenshot for reference..
