android-notifications

问题 I am developing an android-application which main usage is displaying notifications at a set time (some specific calendar app). One of the main complaints is that users do not (always) receive notifications , and I am at wits end. We have internally tested the code below against Android 4.4, 6, 7.0, 7.1, 8.0, 8.1 on emulators and used about 10 real devices (6 to 8.1), and all devices received their notifications on time. Even across reboots, the notifications were all received on time. One of

问题 I used Jobschuler for sending notification every x minutes(determined dynamically) like this ComponentName componentName = new ComponentName(context,ClsJobService.class); JobInfo.Builder builder = new JobInfo.Builder(0, componentName) .setPeriodic(duration * 60 * 1000); //setting in millisecond JobScheduler jobScheduler = (JobScheduler) context.getSystemService (Context.JOB_SCHEDULER_SERVICE); jobScheduler.schedule(builder.build()); and its working great it sends notification on time defined

问题 I have the following scenario. Activity A starts Activity B. B starts a Notification clicking on which another activity C is started. Now the behaviour is different on Gingerbread and ICS onwards. Incase of Gingerbread when I click on the Notification, the expected behavior is seen, however when I run the same code on ICS or JellyBean when I click on the Notification Activity A is destroyed(OnDestroy is called). Why is the lifecycle behavior different. How can I make it to behave in a

问题 I followed the tutorial on Udacity and the developer site for Android auto. I am using a DVU for testing.

问题 I want my app to be able to pick a random item from this string array: <string-array name="quote_list"> <item>Quote 1 </item> <item>Quote 2 </item> <item>Quote 3</item> </string-array> And send the item off in a notification to the user.

问题 Sending messages from one device directly to another device it not supported through Firebase Cloud Messaging. -- Frank van Pufflenen - JUNE 23 2016 That was quite some time ago, and there aren't any updates in the docs.

But is the Firebase Server SDK suitable for this? Can this be implemented using GCM?
