问题 I want to stack notifications using setGroup (as described here: https://developer.android.com/training/wearables/notifications/stacks.html) Basically, I use 0 as notification id (always the same) and builder.setGroup("test_group_key") but a new notification always replaces the previous one.

问题 In attempting to implement notifications in an android app, I am seeing that the notifications no longer work if a user closes the app from the Running App List (top swipe down and then horizontal swipe - not force quit which properly would shut down all future invocations as per google specs).

问题 I have an AsyncTask which starts on boot (called by a service). In some cases I would like to send a notification to start the main Activity. My problem comes when I try to call: NotificationManager notManager = (NotificationManager) getSystemService(ns); where eclipse shows me an error because AsyncTask hasn't got getSystemService method. Any idea? Thank you. 回答1: Because getSystemService is a method of Context class. Check it out here. Before you call the function, create a Context variable

问题 How do i customize the notification icon on the status bar in my phone running Android 5.0. It always comes as a white box(image attached). The notification icon in the notification bar comes colorful as expected but the status bar icon comes as white square box. l 回答1: android 5.0 uses the icon that you give him and puts a color filter on it.
