B4J Question [SOLVED] Can't find variable: google

makis_best · Apr 23, 2020

I have made a simple google map application show some markers using @Erel example.
Until today the application was working fine.

Now I get the error

Waiting for debugger to connect...
Program started.
Error occurred on line: 163 (Main)

I didn't change anything on my code but I get that error.
Why?

Sorry wrong copy paste

B4X:

Sub ComboBox1_SelectedIndexChanged(Index As Int, Value As Object)
    If MarkerList.Size > 0 Then
        For i = 0 To MarkerList.Size - 1
            gmap.RemoveMarker(MarkerList.Get(i))
        Next
        MarkerList.Clear
    End If
    Dim Cb As String
    Cb = ComboBox1.Value
    If Cb = "Όλοι" Then
        Cb = "%"
    Else
        Cb = Cb.SubString2(0,3).Trim
    End If
    Dim Dt1 As String = DateTime.Date(DatePicker1.DateTicks)
    Dim SqlScript As String
    SqlScript = $"SELECT * FROM GPS"$
    Dim rs As ResultSet = sql1.ExecQuery(SqlScript)
    Do While rs.NextRow
        Dim Lo, La As Double
        Lo = rs.GetDouble("Long")
        La = rs.GetDouble("Lang")
        Dim m As Marker = gmap.AddMarker(Lo, La, "Ώρα: " & rs.GetString("Time1")) ---->  Here the code stop
        AttachInfoWindow(m, "Proof: " & rs.GetString("SM"))
        MarkerList.Add(m)
    Loop
    rs.Close
End Sub

AddMarker( Lat, Lon, "Title") looks like you use - lon, lat as param...

Also, do you have an API key for google map?

I do... Where is the problem on that? I don't understand you.

From my #3 post

B4X:

gmap.Initialize2("gmap", options, "xxxxxxxxxxxxxxxxxxxxx")

Try logging results... Catch the error!

B4X:

Do While rs.NextRow
        Dim Lo, La As Double
        Lo = rs.GetDouble("Long")
        La = rs.GetDouble("Lang")
        
        
        ' Log the vars and see what you get...
        Log( "Lat: "&La& "  Long: "&Lo &"  Time1: "&rs.GetString("Time1") )
        
       Try 
           Dim m As Marker = gmap.AddMarker(Lo, La, "Ώρα: " & rs.GetString("Time1")) ---->  Here the code stop
       Catch
           Log(" Last Error: "&LastException.Message)
        End Try

        AttachInfoWindow(m, "Proof: " & rs.GetString("SM"))
        MarkerList.Add(m)
    Loop

Even with Try Catch the error returned is the same

drgottjr · Apr 24, 2020

"google" is google's map api's master object. if it is not found, it means the api was not downloaded successfully from google. why this has happened is hard to say, but downloading the api does not depend on having an api key. (using the api, on the other, hand, would require a valid key). if, in fact, you have changed nothing, then something has changed on the other end (or possibly on your network's end).

for example, i can make a similar error occur simply by not being online when using a google-related map app of mine, thus causing the download to fail and references to "google" throw an error. i'm not suggesting you are not online; i am just telling you what "google" means.

Could it be related with this?

Sudden Issues with Google Maps

Just about an hour ago my app started having issues using google maps when loading the Activity with a MapFragment. Have there been any changes or does anyone know why this might be happening all of a sudden? My App just stops with this error: java.lang.ArrayIndexOutOfBoundsException: length=1...

Google Maps SDK is crashing [Solved]

everything was working fine and out of nowhere my application comes out with this error it doesn't tell me where I don't have how to debug it I don't know what happens

drgottjr · Apr 24, 2020

certainly one possibility (if not the actual reason). always good to have a backup plan. also doesn't hurt to know what "google not found" means. saludos, jja

makis_best · Apr 24, 2020

After I wait for a day and after I clean project then
I get the same error but on different line

B4X:

infoWindow.InitializeNewInstance("com.lynden.gmapsfx.javascript.object.InfoWindow", Null)

makis_best · Apr 25, 2020

I check com.lynden.gmapsfx.javascript.object and I can't see any last change or update but the problem exist

makis_best · Apr 26, 2020

Now... Without to do any other change it works.
Very strange.
Thank you all for your help.
