Android Question If an Intent...

[LucaMs]

What happen if there are no apps able to handle an Intent I "started"?

Ehm... how can I start this "kind" of Intent to test this situation? (I confess that I have not searched if there is a complete list of available Intents, before writing this post, sorry ).

I mean: can I intercept the situation in which an Intent I started can not be "resolved"?


Many thanks in advance.

Found in http://developer.android.com/guide/components/intents-common.html

Caution: If there are no apps on the device that can receive the implicit intent, your app will crash when it calls startActivity(). To first verify that an app exists to receive the intent, call resolveActivity() on your Intent object. If the result is non-null, there is at least one app that can handle the intent and it's safe to call startActivity(). If the result is null, you should not use the intent and, if possible, you should disable the feature that invokes the intent.

resolveActivity is not implemented.

I should study half day or I can wait the Erel's answer

I have found a solution:

Thank you anyway

But if there is an another solution which does not require the Phone Library... thank you.

This code seems to work (to avoid the use of Library Phone):

Sub ResolvableActivity(pIntent As Intent) As Boolean
    Dim r As Reflector
    r.Target = pIntent
    Dim ComponentName As Object
    ComponentName = r.RunPublicmethod("resolveActivity", Array As Object(getPackageManager), Array As String("android.content.pm.PackageManager"))
    Return (ComponentName <> Null)
End Sub

Sub getPackageManager As Object
    Dim context As JavaObject
    context.InitializeContext
    Return context.RunMethod("getPackageManager", Null)
End Sub

If someone wanted confirm... thanks.

There is no reason to avoid the user of the Phone library. It will not add any permissions to your app.

This was exactly what I feared

Thank you
