Android应用下载报错DFDFERH-01：发布后无法下载且大小显示null

Hey there, I get that this DFDFERH-01 error is frustrating—especially since it’s not the usual cache-related case everyone runs into. Let’s break down the specific quirks of your scenario (app showing up in Play Store but un-downloadable with a null size) and work through fixes step by step:

• First, validate your uploaded App Bundle/APK integrity
  The null size display is a big red flag here. Jump into your Play Console’s App Bundle Explorer and check if all split APKs (or your full APK) are properly processed and listed. If any splits are missing or marked invalid, it means your upload didn’t complete correctly. You’ll need to re-generate a signed bundle/APK (double-check your signing key setup!) and re-upload it to the console.

• Verify your release track configuration
  Even if the console says "published," double-check you pushed the release to the Production track, not just an Internal/Closed Testing track. It’s easy to mix these up—if it’s stuck in a testing track, only authorized testers can download it, which explains why regular users (and you on non-tester accounts) can’t access it.

• Test with isolated environments (bypass account/device caches)
  Since common cache fixes don’t apply here, try these targeted checks:

  • On desktop, use an incognito window to search for your app—this skips cached Play Store data tied to your account.
  • On mobile, switch to a Google account that hasn’t been used to test your app before, or clear the Play Store app’s Storage & Cache (Settings > Apps > Google Play Store > Storage > Clear Cache/Clear Storage) and restart your device.

• Check regional/device compatibility restrictions
  Did you accidentally set geo-restrictions or device compatibility filters in the Play Console? For example, if you limited the app to a specific country you’re not in, or excluded certain device architectures, the app might show up in search but be unavailable for download. Head to Release > Setup > Advanced settings > Countries and regions and Device compatibility to confirm.

• Review Play Console error logs
  Dig into the Quality section of your Play Console—look for warnings or errors related to your release, like signature verification failures, missing required permissions, or manifest issues. These often explain why an app is listed but not downloadable.

If none of these steps resolve the issue, reach out directly to Google Play Developer Support through the console—they can access internal logs to pinpoint why the app’s size shows as null and why downloads are blocked.
