我正在使用DownloadManaegr
類從服務器下載Android應用程序。當下載完成時,廣播接收器被註冊。當收到DownloadManager.ACTION_DOWNLOAD_COMPLETE
意圖時,會顯示一個欄通知。要安裝該應用程序,通知應該被複制。這是我正在做的:Android:多次註冊一個接收器
DownloadManager dm = (DownloadManager) DownloadApplicationActivity.this.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request req = new DownloadManager.Request(Uri.parse(MY_LINK));
req.setTitle(MY_TITLE)
.setDescription("Downloading ....")
// download the package to the /sdcard/downlaod path.
.setDestinationInExternalPublicDir(
Environment.DIRECTORY_DOWNLOADS,
MY_PATH);
long enqueue = dm.enqueue(req);
registerReceiver(receiver, new IntentFilter(0DownloadManager.ACTION_DOWNLOAD_COMPLETE));
BroadcastReceiver receiver= new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
int id = 0;
Query query = new Query();
query.setFilterById(enqueue);
Cursor c =dm.query(query);
if (c.moveToFirst()) {
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
// show a notification bar.
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,"",System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.flags |= Notification.FLAG_NO_CLEAR;
Intent i = new Intent(Intent.ACTION_VIEW);
// when the notification is clicked, install the app.
i.setDataAndType(Uri.fromFile(new File(Environment
.getExternalStorageDirectory() + APP_PATH)),"application/vnd.android.package-archive");
PendingIntent pendingIntent = PendingIntent.getActivity(
activity, 0, i, 0);
notification.setLatestEventInfo(activity, MY_TEXT, MY_TEXT,pendingIntent);
notification.number += 1;
notificationManager.notify(id++, notification);
}
}
};
當兩個應用程序同時下載時,只顯示一個通知 - 第二個通知 - 。我錯過了第一個。爲什麼?
我這樣做,notificationManager.notify(id,notification); 我將編輯我的代碼。問題是當兩個應用程序在相同的時間下載時,即在收到任何通知之前,我錯過了第一個通知。 – 2012-07-10 09:26:54
問題是:第二個註冊時,第一個接收器未註冊。 – 2012-07-10 09:33:59
所以阻止你註冊第一個接收者,什麼讓你使用兩個接收器! – AAnkit 2012-07-10 09:35:46
