Android Question Is there any way to stop emulators to use my app

[Addo]

I am suffering from unreal devices and I am not sure if there any way to prevent the app usage under emulators

 

[MarkusR]

you can delete the avd images and so you can start your app only at real devices.

Hello @MarkusR sorry I do not understand do you mean the avd images that installed on my computer ?

If yes this is not the case

I have clients uses my app under unreal device's mostly in emulators with fake android id's

That's why I am trying to prevent emulators

 

[NJDude]

Have you tried searching the forums for "Detect emulator" there are a few threads addressing this.

 

[Addo]

I have searched in b4a forum

I have tried your answer sense 2011 of

Checking if device id is 15 zeros but this isn't effective on emulators sense some emulators like nox have random digits as a device id each creation has a different digits

 

[NJDude]

Yes, is not an easy task.

@PassionDEV
oh, that was a missunderstanding
should not the google licence api prevent others (people that not purchased it) from using your app?

Clean the project

I have searched for long I jave come up with this answer on stackoverflow

https://stackoverflow.com/a/42548916

But the coding part is the issue didn't know how to wrap that on b4a

Or I am not sure if even this answer is effective

What do you need it for?

 

[Addo]

Just I am trying to find a way to detect emulators and stop my app from being runs on emulators sense my app have some fake ids that cannot be controlled by using emulators user can

Spoof his ime
Spoof device id
Spoof psuedo id

Possibly all features that requires rooted phones on normal devices

There are simple ways to check for emulators however they will not work with "malicious emulators" as it is simple to modify the emulator and make it appear as a real device.

The licensing library might be helpful here.

 

[Addo]

I will look at this library

 

[tigrot]

I'll activate the App in each device with a SMS. The emulator is unable to receive and send one. If you need I've got the code.

 

[Addo]

Yes please I would try

You´ll not be able to add functionality to your Device which normally needs an Rooted Device.
