Android Question ALLOW_MOCK_LOCATION

[Deleted member 103]

Hi,

Is there no way to know that this option is enabled?

ALLOW_MOCK_LOCATION
Added in API level 3
String ALLOW_MOCK_LOCATION


This constant was deprecated in API level 23.
This settings is not used anymore.

Setting to allow mock locations and location provider status to be injected into the LocationManager service for testing purposes during application development. These locations and status values override actual location and status information generated by network, gps, or other location providers.

Constant Value: "mock_location"

Thank you Erel,

I have found a solution.

Public Sub isLocationFromMockProvider(location1 As Location) As Boolean
    return nativeMe.RunMethod("isLocationFromMockProvider", Array(GetContext, location1))
End Sub

#Region Subs für Mocklocation
#If JAVA
import android.provider.Settings;
import android.provider.Settings.Secure;
import android.content.Context;
import android.test.mock.MockContext;
import android.location.Location;

public static boolean isLocationFromMockProvider(Context context, Location location) {
    boolean isMock = false;
    if (android.os.Build.VERSION.SDK_INT >= 23) {
        isMock = location.isFromMockProvider();
        return isMock;
    } else {
        if (Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
            return false;
        else {
            return true;
        }
    } 
}
#End If

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

Private 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

Doesn't look like your code is using this import at all. Just delete that line.

If I delete this line then the app crashes with this error message.

Last working version was with B4a 7.81 and android-sdk 26.
If there is no solution, then I have to remove the function.

 

[Erel]

B4A version is not relevant. There is no such method: https://developer.android.com/reference/android/app/Application
Maybe it was removed at some point.

You need to call this method instead: https://developer.android.com/reference/android/location/Location#isFromMockProvider()

B4A version is not relevant.

I know, I just wanted to say that since this version I have made no changes to this app.
