Question

当我尝试从本地通知中打开它时，我的应用程序崩溃了。通知应在5秒后发送，但有时会发送，有时需要更长时间，有时根本不会发送。

public void sendPushNotificationUpdate() {
    new Print("SEND NOTIFICATION");

    AlarmManager service = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(MyService.this, LocalNotification.class);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent pending = PendingIntent.getBroadcast(MyService.this, 0, i, PendingIntent.FLAG_CANCEL_CURRENT);
    Calendar cal = Calendar.getInstance();
    // Start 1 month after boot completed
    cal.add(Calendar.SECOND, 5);
    new Print("send notification at " + cal.getTime());
    //
    // Fetch every 1 month
    // InexactRepeating allows Android to optimize the energy consumption
    // service.setInexactRepeating(AlarmManager.RTC_WAKEUP ,cal.getTimeInMillis(), AlarmManager.ELAPSED_REALTIME , pending);
    service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_HOUR, pending);
}

/////////////////////////////////////////////// /////////////////////////////////

 Intent notificationIntent = new Intent(context, MainActivity.class);
        notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP |
                Intent.FLAG_ACTIVITY_NEW_TASK);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(MainActivity.class);
        stackBuilder.addNextIntent(notificationIntent);

        PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, 0);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        Notification notification = builder
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("TEST")
                .setContentText(title)
                .setSound(soundUri)
                .setAutoCancel(false)
                .setStyle(new NotificationCompat.BigTextStyle()
                        .bigText(title))
                .setPriority(Notification.PRIORITY_MAX)
                .setContentIntent(pendingIntent).build();

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notification);

由于我发送通知，这就是日志显示的内容：

这就是我现在所拥有的。我在互联网上环顾四周，但无法找到解决问题的方法。谢谢你的帮助。

与Unfortunately MyApp has stopped. How can I solve this?不同，我提出了有关本地通知的具体问题。 @ Vlad Matvienko

见这一行：

数据库的SQLiteConnection对象 /data/data/com.test/databases/db.db泄露了！请修理你的应用程序正确结束正在进行的事务并关闭数据库不再需要时。

这意味着您之前使用过数据库，并且没有关闭该对象。现在你正在泄漏数据库。正确处理数据库对象状态。
