Fabric仪表盘Android端多项数据显示0值问题咨询

Hey there, let's break down the issue you're facing and walk through actionable steps to get those metrics back on track:

What's Going On? #

Starting this morning, your Android app's Fabric dashboard is showing 0 values across most key metrics:

• Daily Active Users (DAU)
• Daily New Users
• Latest Version Adoption Rate (0%)
• Median Total In-App Duration (0.0)
  Only the Active Users metric is showing a non-zero number. The good news? This is isolated to just this Android app—all other apps on your Fabric account are working fine. Right now you're running com.crashlytics.sdk.android:crashlytics:1.1.60@aar and plan to upgrade to the latest version.

Let's Troubleshoot #

1. Double-Check SDK Initialization #

First, make sure the Crashlytics SDK is being initialized properly in your app's Application class. Sometimes a small code change can accidentally break this. Here's what the correct setup should look like:

Fabric.with(this, new Crashlytics());

Also, confirm there aren't any conditional checks (like feature flags or environment switches) that are skipping initialization for production builds—this is a common gotcha.

2. Rule Out Network/Upload Issues #

• Ensure your app has the INTERNET and ACCESS_NETWORK_STATE permissions in your AndroidManifest.xml—without these, Crashlytics can't send data to the dashboard.
• Check if there were any recent changes to your network setup (like new firewalls or proxies) that might be blocking outgoing traffic to Fabric's servers.
• Pull device logs and look for errors tagged with CrashlyticsCore or Fabric—these will tell you if data is failing to upload and why.

3. Verify Your Build Configuration #

Mistakes in build setup can also kill metric reporting:

• Check your ProGuard/R8 rules to make sure you're not stripping Crashlytics classes. You should have rules like:

  -keep class com.crashlytics.** { *; }
  -keep class com.google.firebase.crashlytics.** { *; }
  

• Confirm that the Crashlytics dependency is included in your release build variant (it's easy to accidentally exclude it in build.gradle).
• Make sure the app's package name in your build matches exactly what's registered in the Fabric dashboard—mismatches here will cause data to go missing.

4. Go Ahead with the SDK Upgrade #

Since you're already planning to upgrade to the latest Crashlytics version, this is one of the most impactful steps. Older versions like 1.1.60 might have compatibility issues with newer Android versions or recent updates to Fabric's backend.

I recommend rolling out the upgraded SDK to a small beta group first to confirm metrics start showing up before pushing it to all users. That way you can catch any issues early.

5. Check for Partial Platform Outages #

Even though other apps are working, it's worth confirming there's no partial outage affecting your specific app ID or region. Keep an eye on Fabric's status page for any updates related to metric ingestion—sometimes these issues are on the platform side and resolve themselves quickly.

If All Else Fails #

If after trying all the above the metrics still stay at 0, reach out to Fabric support with these details to speed up troubleshooting:

• Your app's exact package name
• Device logs showing Crashlytics initialization and upload attempts
• The exact timestamp when the issue started
• Details about your build (version code, build type, etc.)
