如何使用Android支持库23.2将vectorDrawable用作推送通知的图标? setSmallIcon给出错误

问题描述

我的应用受API< v21，因此我使用Android支持库23.2来管理我的vectorDrawables.

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

 android {
   defaultConfig {
     vectorDrawables.useSupportLibrary = true
    }
 }

所有视图均可正常运行，并带有用于推送通知的图标:

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));

我遇到了错误:

    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 )

在这种情况下如何使用vectorDrawable?可能吗?

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

推荐答案

否，VectorDrawables只能在Android 5.0+设备上的应用程序外部发送-该框架不知道在此之前如何处理vector drawables.

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.
