Hi all,
I use java Inline code to check for Mock Location Enable or Not but receive the error below

public static boolean areThereMockPermissionApps(Context context) {

Thanks for any help

Sub Activity_Create(FirstTime As Boolean)
    If FirstTime Then
    NativeMe.InitializeContext
    End If

   Dim s As Boolean= NativeMe.RunMethod("isMockLocationOn", Null)
     Msgbox(s,"")
End Sub

#If JAVA
public boolean isMockLocationOn(Context context) {
  if (Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
  return false;
  else
  return true;
}
#End If

i guess you need to use IMPORT to include the right java classes to use inline

Thanks DonManfred but I do not know what lib need to be included and how

Thanks DonManfred but I do not know what lib need to be included and how

Start here: https://developer.android.com/reference/android/provider/Settings.Secure.html.
See the fully qualified name for the Settings.Secure import is android.provider.Settings.Secure?

So the first import you need to add is:

#If JAVA
import android.provider.Settings.Secure;

public boolean isMockLocationOn(Context context) {
  if (Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
  return false;
  else
  return true;
}
#End If

Then search the android reference for any other classes: https://developer.android.com/reference/android/content/Context.html will give you the fully qualified name for the Context class etc.
Add the additonal import(s) and you should be good to go.

You're passing the wrong parameter type to your inline java method.
The method wants an instance of android.content.Context but you're passing an instance of your Main class.

Take a look at this code:

Sub GetContext As JavaObject
   Return GetBA.GetField("context")
End Sub

Sub GetBA As JavaObject
  Dim jo As JavaObject
  Dim cls As String = Me
  cls = cls.SubString("class ".Length)
  jo.InitializeStatic(cls)
  Return jo.GetFieldJO("processBA")
End Sub

GetContext should return the instance of android.content.Context that you require:

Dim s As Boolean = NativeMe.RunMethod("isMockLocationOn",GetContext)
