localbroadcastmanager

问题 I just migrated to androidx via the option Refactor -> Move to Androidx option in Android Studio. By default the build.gradle file was using: implementation 'androidx.appcompat:appcompat:1.0.0' I am using LocalBroadcastManager in many places in the project. I could perfectly use import androidx.localbroadcastmanager.content.LocalBroadcastManager with the above v1.0.0 of the androidx.appcompat . But when I update it to 1.1.0 as: implementation 'androidx.appcompat:appcompat:1.1.0' The import is

问题 I'm working on this project in Android in which an aspect requires a CountdownTimer with a foreground service. A few other answers on Stack Overflow mentioned that LocalBroadcastManager would be suitable for my needs. The documentation in Android Developers, however, mentions that it has been deprecated. Any suggestions on what I should use in its place? The documentation mentioned about using LiveData, but I was wondering if there are any easier alternatives. 回答1: LocalBroadcastManager is

问题 A seemingly simple requirement - to update UI from an IntentService . In the shot below, when the Start Service button is clicked, I need to show a ProgressBar above the only TextView and after a delay, remove the ProgressBar . Found a lot of answers on SO, but somehow unable to still crack it. I understand from this that LocalBroadcastManager is a good way to go. I have also tried following this, (an approach with Handler s), but it fails to show the ProgressBar too. Finally, based on this

问题 I have an activity A and a service S. They commute via LocalBroadcastManager. If S calls sendBroadcast twice with two messages M1 and M2 in order, will A get M1 before M2? Thanks, 回答1: LocalBroadcastManager has two ways for you to broadcast; sendBroadcast() and sendBroadcastSync() . One is synchronous, and the other is asynchronous. sendBroadcastSync() blocks until the receiver for the first message is done running. 回答2: Not necessarily. This call deliver method is asynchronous, there is

问题 While it is possible to declare a 'Local' BroadcastReceiver via code so it receives intents published via a LocalBroadcastManager.Ex LocalBroadcastManager.getInstance(this).registerReceiver(new FooReceiver(), new IntentFilter("foo_intent_filter")); I wonder if it is possible to declare such receiver via the manifest .xml (cleaner) . When I use the 'manifest way', the receiver is not 'receiving' the intents. <receiver android:name="FooReceiver" android:enabled="true" android:exported="false" >

问题 I've got this code: private AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE); private PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, new Intent("my action-name"), 0); alarmManager.setInexactRepeating((int)AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + autoUpdateIntervalInMinutes * 60 * 1000, autoUpdateIntervalInMinutes * 60 * 1000, alarmIntent); But I would like to change this for LocalBroadcastManager. Is this possible?
