How can I use vectorDrawable as icon for push notifications using Android Support Library 23.2? setSmallIcon gives error

问题

My app is under API < v21, so I use Android Support Library 23.2 for managing my vectorDrawables.

 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
    }  
 }

All views works ok exept icon for push notification:

NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setColor(getResources().getColor(R.color.colorAccent))
                        .setSmallIcon(R.drawable.ic_play_arrow_white_24dp) //ERROR
                        .setContentTitle(getString(R.string.app_name))
                        .setContentText(getString(R.string.playing));

I've got the error:

    E/AndroidRuntime: FATAL EXCEPTION: main
android.app.RemoteServiceException: Bad notification posted from package com.ashomok.lullabies: Couldn't create icon: StatusBarIcon(pkg=com.ashomok.lullabiesuser=0 id=0x7f020053 level=0 visible=true num=0 )

How can I use vectorDrawable in this case? Is it possible at all?

回答1:

No, VectorDrawables can only be sent outside your app on Android 5.0+ devices - the framework does not know how to handle vector drawables prior to that.
