【UseCase】How to detect if your Android app is running on an emulator?

Sometimes product managers will request
a feature to prevent the app
from running on emulators after release
Here I’ve collected various detection methods
to share

This method uses Android’s Build class to check various hardware and software properties:

Some files only exist in emulator environments, we can check if these files exist:

Emulators typically have specific phone network settings:

Combining all the methods above
to determine if it’s an emulator
But I don’t think every emulator can be perfectly detected
If emulator developers know these detection techniques
they could theoretically create emulators that bypass these methods

The above are just methods that may identify an emulator
In practice, you might encounter the following situations:

1. These methods are not 100% reliable, as emulators can be designed to simulate real devices
   
2. Some real devices might be falsely identified as emulators (if a manufacturer’s device happens to be missing properties or characteristics you’re checking)
   
3. Consider a different approach:
   you could specifically block emulators you’ve encountered
   

• Combine multiple detection methods to improve accuracy

• Regularly update detection logic to adapt to new emulators
  This might need to be handled case by case
  Since QA will help test
  When issues arise
  they can report them to you
  so you can address the specific problems
  

• Consider whether this method is necessary
  to avoid affecting user experience due to false positives
  

• While these techniques can provide useful information
  they are not absolutely reliable
  Before implementing any logic based on these detection results
  please consider potential impacts and necessity.
