我在我的應用程序中創建了一個通知，但是當我點擊按鈕來顯示它時，從不顯示並且日誌貓沒有顯示任何錯誤。我不知道該做什麼。我的通知不會顯示從不
import android.support.v4.app.NotificationCompat;
Intent resultIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("content://" + fileDir));
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent, /* <---- el intent que se realiza al hacer click*/
PendingIntent.FLAG_UPDATE_CURRENT
);
//TODO creamos notificacion
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setWhen(System.currentTimeMillis())
.setTicker("Downloader PRO")
.setContentTitle(getText(R.string.notificacion_titulo))
.setContentText("prueba")
.setContentIntent(resultPendingIntent)
.setContentInfo(getText(R.string.notificacion_informacion));
mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
//TODO mostramos la notificacion
// Sets an ID for the notification
int mNotificationId = 001;
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(mNotificationId, mBuilder.build());

IDK現在做什麼，在任何設備工程....
確保您的應用程序的信息已通知檢查 –
我如何檢查呢？？ – Toni
