报警，并发出通知，通知不会弹出 [英] Alarm with notification, notification wont pop up

问题描述

所以我不知道为什么会这样code不工作。我想提出一个报警通知，将熄灭，每日一次。只是想说，我是新来的机器人。改变了code有点几次，但仍然无法工作。

  

报警方式通知执行不太多，但我得到这个：-248 /？ D / PowerManagerService：releaseWakeLock标志=为0x1 =标签AlarmManager W / ActivityManager：无法启动服务意向{FLG =为0x4 = CMP com.example.polakken.test / .lol（有演员）}：找不到06-13 00:00 ：00.825 231-267 /？ D / PowerManagerService：acquireWakeLock标志=为0x1 =标签06-13 AlarmManager 00：00：00.825 231-248 /？ D / PowerManagerService：releaseWakeLock标志=为0x1 =标签AlarmManager

我的code：

 公共类MainActivity扩展ActionBarActivity {@覆盖

        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.activity_main）;        共享preferences preferences = preferenceManager.getDefaultShared preferences（本）;

解决方案

您所创建的的PendingIntent 与 PendingIntent.getService（），但你提供一个意图与活动。

因此​​，对于你code工作，你需要使用<一个href=\"http://developer.android.com/reference/android/app/PendingIntent.html#getActivity(android.content.Context,%20int,%20android.content.Intent,%20int)\"相对=nofollow> PendingIntent.getActivity（） 。
（另外，你必须添加相应的＆LT;活动方式＆gt; 标记你的的Andr​​oidManifest.xml ）

不过，这可能不是正是你想要的一切：哈哈活动做的唯一事情就是添加一个通知。您可能需要使用广播接收器（或者一个 WakefulBroadcastReceiver ）代替。在这种情况下，你需要使用<一个href=\"http://developer.android.com/reference/android/app/PendingIntent.html#getBroadcast(android.content.Context,%20int,%20android.content.Intent,%20int)\"相对=nofollow> PendingIntent.getBroadcast（）而不是 getActivity（）。

So I don't know why this code is not working. I wanted to make an "alarm" notification that would go off once a day. Just wanted to say I'm new to android. Changed up the code a bit couple of times but still wont work.

Alarm method executes notification does too but I get this : -248/? D/PowerManagerService﹕ releaseWakeLock flags=0x1 tag=AlarmManager W/ActivityManager﹕ Unable to start service Intent { flg=0x4 cmp=com.example.polakken.test/.lol (has extras) }: not found 06-13 00:00:00.825 231-267/? D/PowerManagerService﹕ acquireWakeLock flags=0x1 tag=AlarmManager 06-13 00:00:00.825 231-248/? D/PowerManagerService﹕ releaseWakeLock flags=0x1 tag=AlarmManager

My Code:

public class MainActivity extends ActionBarActivity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        SharedPreferences.Editor editor = preferences.edit();
        int i = preferences.getInt("numberoflaunches", 1);

        if (i < 2) {
            alarmMethod();
            i++;
            editor.putInt("numberoflaunches", i);
            editor.commit();
        }

        if (savedInstanceState == null) {
            splashMethod();

        }


    }

//...

private void alarmMethod() {
        Intent intentbro = new Intent(this, lol.class);
        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        PendingIntent pendingIntent = PendingIntent.getService(this, 0, intentbro, 0);

        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.MINUTE, 0);
        calendar.set(Calendar.HOUR, 0);
        calendar.set(Calendar.AM_PM, Calendar.AM);
        calendar.add(Calendar.DAY_OF_MONTH, 1);

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60 * 60 * 24, pendingIntent);


        Toast.makeText(MainActivity.this, "start alarm", Toast.LENGTH_LONG).show();

    }

//notification class

public class lol extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        NotificationCompat.Builder b = new NotificationCompat.Builder(this);

        Intent intent1 = new Intent(this.getApplicationContext(), MainActivity.class);
        PendingIntent pIntent = PendingIntent.getActivity(this, 1, intent1, 0);

        b.setContentText("lol");
        b.setContentTitle("Default notification");
        b.setSmallIcon(R.drawable.iconography_small_size);
        b.setContentIntent(pIntent);

        NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(1, b.build());

    }
}

解决方案

You are creating the PendingIntent with PendingIntent.getService(), but you are supplying an Intent with an Activity.

So for your code to work you would need to use PendingIntent.getActivity(). (Additionally you have to add the corresponding <activity> tag to your AndroidManifest.xml.)

However, this is probably not exactly what you want: The only thing the lol Activity does is adding a notification. You might want to use a BroadcastReceiver (or perhaps a WakefulBroadcastReceiver) instead. In this case you would need to use PendingIntent.getBroadcast() instead of getActivity().
