Android：在Play商店进行内部测试时，未知手机崩溃

Question

I've implemented Fabric (Crashlytics) in my app. Since yesterday I started an internal test on the Play Store. I created a new APK with a new version number. Only two people have been added to this internal test (which includes myself and a coworker). This morning I got some crashes from Fabric. But these crashes are from unknown phones: A rooted Samsung Galaxy S5 on Android 4.4.2 and a Samsung Galaxy J7 on Android 6.0.1. Where are these crashes coming from?

Edit

Internal testing on the Play Store is new. It is like Beta or Alpha builds (so only available for testers added to it).

Answer 1

I suspect this is from Google's pre-launch report . When you upload an APK to an alpha, beta or testing track Google automatically runs your app on a number of devices to test quality.

Answer 2

We've experienced this on multiple projects too.

We assume that some third party stores, like apkpure , grabbed our apks from the playstore to list them in their store.

So those logs will either be from their internal testing devices, or from users that installed the app from the third party store.

We've found that all of our apps that have mysterious logs from unknown rooted devices are listed in one ore more third party stores.

But again, this is only an assumption.
