B4A, I am suppling the end user a list of installed applications (without system).
but I need also to supply the name of the provider.

Sub popPack
    Dim obj1, obj2, obj3 As Reflector
    Dim size, flags As Int
    Dim name, label As String
    obj1.Target = obj1.GetContext
    obj1.Target = obj1.RunMethod("getPackageManager") 'packageManager
    obj1.Target = obj1.RunMethod2("getInstalledPackages", 0, "java.lang.int") 'List packages
    size = obj1.RunMethod("size")
    Dim y As Int = 0
    For i = 0 To size - 1
        obj2.Target = obj1.RunMethod2("get", i, "java.lang.int") 'package info.
        name = obj2.GetField("packageName")
        obj3.Target = obj2.GetField("applicationInfo") 'application Info.
        flags = obj3.GetField("flags")
        Dim x As String = flags
        If Bit.And(flags, 1) = 0 And x.StartsWith(9) Then 'app is not in system image
           Dim pm As PackageManager         'phone library
           label = pm.GetApplicationLabel(name)
           myspin(y) = label
           y = y + 1
        End If
    Next
End Sub

I don't see any GetProviderName method. There is a getProviderInfo method but it is not relevant. It allows you to find information about the app's content providers.

Erel Thanks for your help.
by the way, can we learn any thing from the "flags" number
if starts for example with "9." or "4."

You can check whether a flag is set with:
https://developer.android.com/reference/android/content/pm/ApplicationInfo.html#FLAG_ALLOW_BACKUP

Dim FLAG_ALLOW_BACKUP As Int = 0x00008000
If Bit.And(flags, FLAG_ALLOW_BACKUP) <> 0 Then
 'it is set
End If
