我使用下面的代碼調(diào)用 Broadcast serviceIntent 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 從來沒有被調(diào)用，哪里出錯(cuò)了呢？

TA貢獻(xiàn)1805條經(jīng)驗(yàn) 獲得超10個(gè)贊
Intent i = new Intent(this, BootUpReceiverRecall.class); sendBroadcast(i);
為什么要這樣寫呢？ 我是沒這樣寫過
廣播分2中注冊(cè)方式：
1中是代碼注冊(cè),局部廣播 可以寫在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 節(jié)點(diǎn)下
創(chuàng)建 YourReceiver在xx.xx.xx.receiver（隨便寫）包下 extends BrocastReceiver
根據(jù)action過濾
你這個(gè)可改成
Intent i = new Intent(“action”); sendBroadcast(i);
