目前我正在通知用户下载已完成：

@Override
protected void onHandleIntent(Intent intent) {

    String url = intent.getStringExtra("url");
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
    request.setDescription("Downloading");
    request.setTitle("Bob_Marley-Jammin.mp3");

    request.allowScanningByMediaScanner();

    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);

    request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "Bob_Marley-Jammin.mp3");

    DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    manager.enqueue(request);

}

}

但是当用户点击通知时，应用程序强制关闭。有人知道为什么吗？

我想要发生的是当用户单击启动特定活动的通知时。

这是我的 logcat 东西：
