Broadcast service 没有被调用
论文问答
1
我使用下面的代码调用 Broadcast service
Intent i = new Intent(this, BootUpReceiverRecall.class);
sendBroadcast(i);
<receiver android:process=":remote" android:name="BootUpReceiverRecall"></receiver>
public class BootUpReceiverRecall extends BroadcastReceiver
{
// Restart service every 30 seconds
private static final long REPEAT_TIME = 1000 * 30;
@Override
public void onReceive(Context context, Intent intent)
{
AlarmManager service = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, BootUpReceiver.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar cal = Calendar.getInstance();
// Start 30 seconds after boot completed
cal.add(Calendar.SECOND, 30);
//
// Fetch every 30 seconds
// InexactRepeating allows Android to optimize the energy consumption
service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), REPEAT_TIME, pending);
// service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
// REPEAT_TIME, pending);
}
但是我的BootUpReceiver 从来没有被调用，哪里出错了呢？

广播分2中注册方式： 1中是代码注册,局部广播 可以写在Activity中
YourReceiver reveiver = new YourReceiver (); IntentFilter filter = new IntentFilter(); filter.addAction("yourAction"); registerReceiver(reveiver , filter);Activity生命周期中可以管理register 和 unregister 2.manifest配置 节点下 创建 YourReceiver在xx.xx.xx.receiver（随便写）包下 extends BrocastReceiver 根据action过滤
你这个可改成
Intent i = new Intent(“action”); sendBroadcast(i); -
要在 AndroidManifest.xml 中定义：
<receiver android:process=":remote" android:name=".BootUpReceiverRecall" />还要查看 "android:name" tag。 如果在程序的同一个包中的话，要在 "BootUpReceiverRecall" 前面添加一个"."。但是不能这样使用 "app.package.receivers.BootUpReceiverRecall".
