Android Question Crash when gathering email clients

[andyp]

App was working fine, until an android update.

Now my app crashes when gathering a list of installed email clients

Sub GetEmailPackage As String
    Dim PM As PackageManager, DummyIntent As Intent, DummyIntent2 As Intent
    Dim EmailActivities As List, EmailAppNames As List, iPackage As Int, x As Int, tempString As String
    EmailActivities.Initialize: EmailAppNames.Initialize
    
    DummyIntent.Initialize("android.intent.action.SENDTO", "mailto:[email protected]")
    EmailActivities = PM.QueryIntentActivities (DummyIntent)

    If EmailActivities.Size = 0 Then
        DummyIntent2.Initialize("android.intent.action.SENDMULTIPLE", "")
        DummyIntent2.SetType ("message/rfc822")
        EmailActivities = PM.QueryIntentActivities (DummyIntent2)
    End If

    If EmailActivities.Size = 0 Then Return ""

    ' Get app labels & icons
    For x = 0 To EmailActivities.Size - 1
        Dim imgIcon As BitmapDrawable
        Dim sPackageName As String = EmailActivities.Get(x)
        sPackageName = sPackageName.SubString2 (0, sPackageName.IndexOf ("/"))
        tempString = PM.GetApplicationLabel(sPackageName)
        imgIcon = PM.GetApplicationIcon(sPackageName) 'App icon if desired
        EmailAppNames.Add (tempString)
    Next

    iPackage = InputList (EmailAppNames,"Send email using",-1)
    If iPackage = DialogResponse.CANCEL Then Return "/cancel/"

    Return EmailActivities.Get (iPackage)

End Sub

error log:

Thank you for any help

You should run your app in debug mode to see the exact error line. It is here:

imgIcon = PM.GetApplicationIcon(sPackageName)

You shouldn't assume that GetApplicationIcon will return a BitmapDrawable. It can return other types of drawables.

A simple solution is to skip other types:

Dim o As Object = PM.GetApplicationIcon(sPackageName)
If o Is BitmapDrawable Then
 imgIcon = o
End If

Another option is to draw the drawable with Canvas.DrawDrawable.
