创建 Android 通知时出现异常

Question

在我的应用程序中，我使用以下代码构建了一个通知：

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification.Builder notificationBuilder = new Notification.Builder(this)
    .setSmallIcon(R.drawable.ic_notify_nursing)
    .setOngoing(true)
    .setContentTitle(getString(R.string.feeding_in_progress));

if(android.os.Build.VERSION.SDK_INT >= 21) {
    notificationBuilder.setVisibility(Notification.VISIBILITY_PUBLIC);
}

Intent resultIntent = new Intent(this, MainActivity.class);

PendingIntent resultPendingIntent = PendingIntent.getActivity( this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notificationBuilder.setContentIntent(resultPendingIntent);

if(android.os.Build.VERSION.SDK_INT >= 16) {
    notificationManager.notify(NOTIFICATION_TAG, NOTIFICATION_ID, notificationBuilder.build());
} else {
    notificationManager.notify(NOTIFICATION_ID, notificationBuilder.getNotification());
}

在 Google Play 控制台中，我看到为这一行记录了许多异常：

notificationManager.notify(NOTIFICATION_TAG, NOTIFICATION_ID, notificationBuilder.build());

大部分错误发生在Android 5.0 和 5.1 中，旧版本没有问题。堆栈跟踪看起来像：

知道这里发生了什么吗？

Answer 1

改用 NotificationCompat.Builder 可以使您的代码更简单并避免意外。

Answer 2

从 API 11 开始，该方法似乎已被弃用，如下所述..

Answer 3

根据 notification guide list of required fields, you must set the content text via the setContentText() 方法。注意这里可以留空，但是需要设置
