android5.0使用Notification报RemoteServiceException的解决办法

来源：互联网发布：union软件安卓编辑：程序博客网时间：2024/04/26 10:15

有时android5.0下使用Notification会报如下错误信息（比如开启重启动系统就要发送通知）
android.app.RemoteServiceException: Bad notification posted from package *: Couldn't create icon: StatusBarIcon

这个问题多数集中在setSmallIcon(R.drawable.scanner_small)这句代码上，在某些情况下（比如开启重启动系统就要发送通知），R.drawable.scanner_small这个资源尚未准备好，导致了App异常。那怎么办呢？

这是android5.0的bug，在android4.4和6.0中都正常，一般情况下，这没办法解决，如老外说的那样

不过，如果你不介意图标大小，可以这样写：
setSmallIcon(context.getApplicationInfo().icon)
从ApplicationInfo中拿到应用icon当作SmallIcon。
总之，要抢在系统重启动之前拿到icon，而不至于拿到一个空的resId。

附上我完整的Notification代码

private static final int NOTIFY_ID = 0;public static void showCustomNotification(Context context) {NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);Intent intent = new Intent(context, MainActivity.class);//intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);// FLAG_ONE_SHOTintent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);PendingIntent contentIntent = PendingIntent.getActivity(context, 0,intent, PendingIntent.FLAG_UPDATE_CURRENT);NotificationCompat.Builder mBuilder = new Builder(context);        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.custom_notify);                boolean isScan=(Boolean)SPUtils.get(context, App.KEY_SCAN, true);        remoteViews.setTextViewText(R.id.btn_scan,isScan?"隐藏扫描键": "显示扫描键");        //点击事件处理        Intent actionIntent = new Intent(App.ACTION_NOTIFICATION);        actionIntent.putExtra(App.KEY_NOTIFICATION_CLICK, isScan);        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 1, actionIntent, PendingIntent.FLAG_UPDATE_CURRENT);        remoteViews.setOnClickPendingIntent(R.id.btn_scan, pendingIntent);        mBuilder.setContent(remoteViews)                .setContentIntent(contentIntent)                .setTicker("扫描精灵")                .setWhen(System.currentTimeMillis())                .setAutoCancel(true)                .setSmallIcon(context.getApplicationInfo().icon)//采用quick fallback image.setDefaults(Notification.DEFAULT_ALL);                Notification notify = mBuilder.build();        notify.flags = Notification.FLAG_NO_CLEAR;//|Notification.FLAG_ONGOING_EVENT;        notificationManager.notify(NOTIFY_ID, notify);}
