我正在尝试使用JakeWharton 的 NotificationCompat2。NotificationCompat2 的文档说

只需将您的导入从 android.support.v4.app.NotificationCompat 更改为 com.jakewharton.notificationcompat2.NotificationCompat2 并使用 NotificatonCompat2.Builder 类。

我已将导入更改为com.jakewharton.notificationcompat2.NotificationCompat2并使用以下代码

Notification notification = new NotificationCompat2.Builder(
        MainActivity.this).setContentTitle("Basic Notification")
        .setContentText("Basic Notification, used earlier")
        .setSmallIcon(R.drawable.lock).build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager notificationManager = (NotificationManager)
        getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);

并且应用程序因以下错误而崩溃

08-17 20:14:32.400: E/AndroidRuntime(289): FATAL EXCEPTION: main
08-17 20:14:32.400: E/AndroidRuntime(289): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.xyz.notificationchk/com.xyz.notificationchk.MainActivity}: java.lang.IllegalArgumentException: contentIntent required: pkg=com.wissenways.notificationchk id=0 notification=Notification(vibrate=null,sound=null,defaults=0x0)

我的问题

我遗漏了什么或编码错误导致应用程序崩溃？

我不知道错误是什么，但这段代码有效

private static final int UPDATE_PROGRESS = 123654789;
private NotificationManager notifManager;
private Context mContext;
private NotificationCompat2.Builder mNotification;
private String content = "";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mContext = MainActivity.this;
    notifManager = (NotificationManager)
                    mContext.getSystemService(mContext.NOTIFICATION_SERVICE);
    mNotification = new NotificationCompat2.Builder(mContext)
            .setSmallIcon(android.R.drawable.sym_def_app_icon)
            .setTicker("Launch download")
            .setContentTitle("Downloader")
            .setContentText(content)
            .setContentIntent(getPendingIntent());
    notifManager.notify(UPDATE_PROGRESS, mNotification.build() );
}

private PendingIntent getPendingIntent() {
    Intent i = new Intent(mContext, MainActivity.class);
    i.setFlags(FLAG_ACTIVITY_CLEAR_TOP);
    return PendingIntent.getActivity(mContext, 0, i, 0);
}
