Android Question java.lang.nullpointerexception

[Tomas Petrus]

hi guys
another problem ... on all my devices everything works fine.

but google pre release testing and some testers from client end up with:

[B]java.lang.NullPointerException[/B]:
at cz.esol.xxxxxxx.main._geocoder1_geocodedone (main.java:973)
at java.lang.reflect.Method.invoke (Native Method)
at anywheresoftware.b4a.BA.raiseEvent2 (BA.java:186)

at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:797)
at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:687)

The code responsible for that is this:

Sub Geocoder1_GeocodeDone(Results() As Address, Tag As Object)
    If Results <> Null Then 
        If Results.Length>0 Then
            Dim Address1 As Address
            Dim i As Int
            For i=0 To Results.Length-1
                Address1=Results(i)
....

I tried to handle it by "If Results <> Null Then" but it seems it doesnt work. the worst thing is that I cant simulate that on any of my devices.
So I cant play around and try different things because that hellish error never apear to me whatever I do.

Thanks for advices

EDIT: found out that this one with illegal state is from the old version of app. So it is solved by the new one. But anyway how to read / debug this ?

and another from google reports.. this one I even dont know where to start looking..for the prob.
adding view in job done ? Loading content of webview in job done ? no clue...

from google prelease testing I got from some devices:

FATAL EXCEPTION: main
Process: cz.esol.xxxxxxx.main, PID: 11487
java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.length()' on a null object reference
   at cz.esol.xxxxxxx.main._geocoder1_geocodedone(main.java:973)

checked API key in manifest seems fine

'************ Google API KEY ************
AddApplicationText(
<meta-data
  android:name="com.google.android.geo.API_KEY"
  android:value="AIza...."/>
)

geocoding is called like this

If Starter.LastLocation.IsInitialized = True Then
        Geocoder1.GetFromLocation(Starter.LastLocation.Latitude, Starter.LastLocation.Longitude, 1, Null)
End If

 

[Tomas Petrus]

could it be that I used some old geocode ?
implemented new one over HTTPS and going to give it a try

Hard to say as you are not given enough informations....

Post a small project which shoes the issue.

 

[Tomas Petrus]

changed it to:

If Starter.LastLocation.IsInitialized = True Then
       Dim GetAddressJob As HttpJob
       GetAddressJob.Initialize("GeoCoding", Me)
       GetAddressJob.Download2("https://maps.googleapis.com/maps/api/geocode/json", Array As String("latlng", Starter.LastLocation.Latitude & "," & Starter.LastLocation.Longitude, "key", Config.API_Key) )
   End If

and seems it helped
