android - 显示通知后崩溃应用程序

Question

我想创建一个通知，但应用程序在调用最后一行后崩溃了。

    NotificationCompat.Builder notification = 
            new NotificationCompat.Builder(this)
            .setContentTitle("My notification")
            .setContentText("Hello World!");

    NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    mNotificationManager.notify(1, notification.build());

在 LogCat 中我发现了这个:

我在 Android 版本 2.3.7 的手机上试了一下。有帮助吗？

java.lang.IllegalArgumentException: contentIntent required: pkg=com.example.test id=1 

您没有给您的通知一个 contentIntent，因为您使用的是 Compat 版本，您必须提供一个 Intent(当用户点击通知时打开的 Activity )或者如果您使用 RemoteViews，您可以使用应用于单个 View 的 PendingIntents .
