Question

My question is pretty closed to reacting-to-a-click-on-a-preference

I want to use Intent + android:action in my R.xml.preferences file instead of setting up OnClickListener on a certain preference item as below

    <Preference android:title="@string/pref_cat3_call_center">
        <intent
            android:action="android.intent.action.DIAL"
            android:data="1112223333" />
    </Preference>

While I always encounter the exception

android.content.ActivityNotFoundException: 
No Activity found to handle Intent { act=android.intent.action.DIAL dat=+1112223333}

Is this idea possible, or I have to use OnClickListener?

Answer 1

Phone apps support Uri 's in the form of tel:XXX .

Change your android:data value to "tel:1112223333"

See: https://developer.android.com/reference/android/content/Intent#ACTION_DIAL

Input: If nothing, an empty dialer is started; else getData() is URI of a phone number to be dialed or a tel: URI of an explicit phone number .
