Android Question Check the source where an app was installed from

[KMatle]

Is it possible to check (within the app by code) which the source was the app was installed from? (Google Play or other)

 

[Erel]

Sub GetInstallerPackageName As String
   Dim jo As JavaObject
   jo.InitializeContext
   jo = jo.RunMethod("getPackageManager", Null)
   Dim o As Object = jo.RunMethod("getInstallerPackageName", Array(Application.PackageName))
   If o = Null Then Return "N/A" Else Return o
End Sub

Is this code suitable and not hackable for paid app, so it should not installed from other sources like copying ...
Or there is another and better scenario?

 

[Erel]

It is "hackable". A hacker can remove this check or modify it as needed. It is also possible to change the "installer package name" with ADB.
