在我的代码中，我在 Android 清单文件上添加了 Boot Completed 的所有权限。我登录了我的广播接收器，重新启动后控件将进入广播接收器但警报没有触发。实际上我想要的是一个活动在之后启动触发警报..在正常情况下（关闭前）我收到警报并启动了活动..重新启动后它没有发生......

这是我的广播接收器

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();
        }

}

我有问题

在未决意图中，我使用了要启动的活动..那是错误..在未决意图中，您应该使用广播接收器作为意图...

if (sp.getBoolean(BigBirdConstants.pref_alarm_set, false)) {
                String alrm = sp.getString(
                        BigBirdConstants.pref_myflight_alarm_time, "hello");
                String alrmtime[] = new String[2];


                    alrmtime = alrm.split(":");

                    Calendar cal = new GregorianCalendar();
                    cal.setTimeInMillis(System.currentTimeMillis());
                    /*
                     * Integer.parseInt(alrmtime[
                     * 0])
                     */
                    /* Integer.parseInt(alrmtime[1]) */
                    cal.set(Calendar.HOUR_OF_DAY,11);
                    cal.set(Calendar.MINUTE,13);
                    cal.set(Calendar.SECOND, 0);
                    cal.set(Calendar.MILLISECOND, 0);

                    Intent intent1 = new Intent(context,
                            AlarmReceiver.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, 192837, intent1,PendingIntent.FLAG_UPDATE_CURRENT);
                    Log.d("hai",
                            "alarm set");
