ClassNotFoundException when app launch

Question

I created an Andriod app for a Chinese Newspaper Company.

From the Exception/ANR report of Google Play Store, it was found that some users encountered the problem of ClassNotFoundException when they launch the app. The app cannot found the activity marked as

<category android:name="android.intent.category.LAUNCHER" />

The frequency is about every 3 sessions out of 500000. What are the possibilities leading to ClassNotFoundException?

Remakrs: I doubt if this related to the package name. In the first few lines of AndroidManifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.abc.news"

the source code are stored in different folder name (Real file storage place)

com.anotherCompany.abc

so.. in the activity tag (AndroidManifest)

<activity
   android:name="com.anotherCompany.abc.MainActivity"
   android:label="@string/app_name"

Thank you for your time

If this happens rarely, I think you shouldn't worry too much about it.

It can be due to a bad installation, a bad phone backup, or some android mods. But probably not something related to your code.
