Question

我想创建一个通知，但是在调用最后一行后应用程序崩溃了。

    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 2.3.7版的手机上试用。有什么帮助吗？

Answer 1

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

您没有向contentIntent发送通知，因为您使用Compat版本，您必须提供Intent（当用户点击通知时要打开的活动）或者如果您使用RemoteView，您可以使用应用于各个视图的PendingIntents

请参阅：http://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#setContentIntent(android.app.PendingIntent)

Answer 2

您应该将意图传递给通知。

显示通知后崩溃应用程序
