Android BroadcastReceiver

1. 在AndroidManifest.xml定义相关权限：

<uses-permission android:name="android.permission.WAKE_LOCK" />

2. 在Main Activity中建立AlarmManager:

Intent  intent = new Intent(MainActivity.this, AlarmReceiver.class);

pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);

am.set(AlarmManager.RTC_WAKEUP, Schedule_Time, pendingIntent);

3. 在Receiver中建立响应：

public class AlarmReceiver extends BroadcastReceiver

{

@Override

public void onReceive(Context context, Intent intent)

{

Intent i = new Intent(context, ActionActivity.class);

Bundle bundleRet = new Bundle();

bundleRet.putString("STR_CALLER", "");

i.putExtras(bundleRet);

i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(i);

}

}
