broadcastreceiver

问题 I need some help to understand when I can expect my broadcast receiver will work when just registered in the manifest versus having to be registered from a running activity or service. So for example if I register a stand alone receiver with the following intent filter it works without having a service/activity reference to it: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.blk_burn.standalonereceiver" android

问题 I am trying to start up a BroadcastReceiver within a Service . What I am trying to do is have a background running service going that collects incoming text messages, and logs incoming phone calls. I figured the best way to go about this is to have a service running that incorporates a broadcast receiver that can catalog either. How do i go about doing this? I already have my service up and running. 回答1: as your service is already setup, simply add a broadcast receiver in your service:

问题 I have a BroadcastReceiver that listens to a locale change. Here's my problem: I navigate to an Activity and then want to change locale (language setting) which I do by going to the settings app. The BroadcastReceiver then listens in onReceive() once a change is made. I then navigate back to the app and when I do so I'd like to take a user to another Activity . Also, a locale modification corresponds to a change in configuration which means an Activity will be destroyed and created again.

问题 I wanted to collect log for every event which occurs in android device like when user starts any application or when any application have notification for user. Currently I have broadcast receiver listening for every event but it did not listened to certain events, so I searched on internet and it suggested to give priority to events while registering then in manifest file. Now the question is should I give priority to every event and if yes what priority should I give them. Thanks. 回答1:
