在我的代码中，我在Android清单文件中添加了Boot Completed的所有权限。我记录了我的广播接收器，重启后控件进入广播接收器但是警报没有启动。我想要的是一个活动触发报警后启动。正常情况下（关机前）我收到报警并启动活动。重启后没有发生......
这是我的Boadcast接收器
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d("hai", "inside onreceive");
try {
if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
Calendar cal = new GregorianCalendar();
cal.setTimeInMillis(System.currentTimeMillis());
cal.set(Calendar.HOUR_OF_DAY,9);
cal.set(Calendar.MINUTE,49);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
Intent intent1 = new Intent(context,
AlarmLauncher.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent1.putExtra("alarm_message", "feathersoft Rules!");
// In reality, you would want to have a static variable
// for the request code instead of 192837
PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent1,PendingIntent.FLAG_CANCEL_CURRENT);
Log.d("hai",
"alarm set");
// Get the AlarmManager service
AlarmManager am = (AlarmManager) context
.getSystemService(context.ALARM_SERVICE);
// am.set(AlarmManager.RTC_WAKEUP,
// cal.getTimeInMillis(), sender);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
sender);
Log.d("hai",
"Alarm Alert:Inside the boot completed broadcast receiver......");
Log.d("hai",
"Alarm Alert:Inside the boot completed broadcast receiver......");
}
}
}catch (Exception e) {
Toast.makeText(
context,
"There was an error somewhere, but we still received an alarm",
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
try {
if(intent.getAction().equals(null))
{
SharedPreferences sp = context
.getSharedPreferences(
BigBirdConstants.nameOfPreference,
context.MODE_PRIVATE);
String alrm = sp.getString(
BigBirdConstants.pref_myflight_alarm_time, "hello");
Log.d("hai", alrm);
Intent newIntent = new Intent(context, AlarmLauncher.class);
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
System.out.println("boot completed");
// newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(newIntent);
}
}catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
这是我重启后的警报转储

我遇到了问题
在未决意图中，我使用了要启动的活动。但是故障......在未决意图中你应该使用你的广播接收器作为意图...
