I am trying to use alarm manager to show notification after 5 sec. I have tried many sites but was not able to understand please give a simple example for explaining how to use alarm manager and connect notification with it.
I am newbie.
this is function i used to set alarm and I am not getting notification after 5 secs actually not at all not in emulator nor in android mobile. If put code to create notififcation with a button pressing that is working great.
public void setAlarm(View view)
{
Intent alertIntent = new Intent(this, AlertReciver.class);
Long alertTime = new GregorianCalendar().getTimeInMillis()+5*1000;
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, alertTime, PendingIntent.getBroadcast(this, 1, alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
tv.setText("completed");
}
and this class to make it work
public class AlertReciver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
createNotification(context,"times Up", "5 SEcond has passed", "Alert");
}
public void createNotification(Context context,String msg, String msgText, String msgAlert){
PendingIntent notificIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ne)
.setContentTitle(msg)
.setTicker(msgAlert)
.setContentText(msgText);
mBuilder.setContentIntent(notificIntent);
mBuilder.setDefaults(NotificationCompat.DEFAULT_SOUND);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}

I want to start a notification in current Activity which is ChatActivity. When I press the notification, I want to enter the ChatOneActivity.
However I don't want the current ChatActivity finished when I'm in the ChatOneActivity. Because I'm receiving the data and when I press the back button, I want to stay in the ChatActivity.
The point is I do not want the ChatActivity to finish, no matter which Activity I am currently in.
So what should I do?
Here is the code
private void showNotification(String id, String message) {
NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(android.R.drawable.sym_action_email)
.setContentTitle("You have a new message")
.setContentText(message);
Intent intent = new Intent(ChatActivity.this,ChatOneActivity.class);
intent.putExtra("toId", id);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(ChatActivity.this);
stackBuilder.addParentStack(ChatOneActivity.class);
stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_CANCEL_CURRENT);
builder.setContentIntent(pendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, builder.build());
}
The problem is:
Now I enter the ChatOneActivityand when I press the back button, I return to the desktop. Means that the ChatActivity has already finished which I don't want.
Here is the mainfest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.webmobilegroupchat"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="16" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.webmobilegroupchat.MainActivity"
android:label="#string/app_name" >
</activity>
<activity
android:name="com.example.webmobilegroupchat.ChatActivity"
android:label="#string/title_activity_chat" >
</activity>
<activity
android:name="com.example.webmobilegroupchat.ChatOneActivity"
android:label="#string/title_activity_chat_one" >
</activity>
<activity
android:name="com.example.webmobilegroupchat.SplashActivity"
android:label="#string/title_activity_splash" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Try this on ChatOneActivity activity .
#Override
public void onBackPressed() {
super.onBackPressed();
Intent intent = new Intent(getApplicationContext(),ChatActivity.Class);
startActivity(intent);
}
your code is looking fine for creating notification but you have to define parent activity in Manifest also to navigate back, stackBuilder.addParentStack assumes that you define it in Manifest as well for API 16+:
<activity android:name=".ChatOneActivity"
android:parentActivityName=".ChatActivity"
... />
for < API 16:
<activity android:name=".ChatOneActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".ChatActivity" />
I'm trying to configure an alarm notification in Android and unfortunately no alarm is generated.
Here is the creation of the alarm:
myDate = new SimpleDateFormat("dd/MM/yyyy HH:mm").parse(time_Date_str);
t.setDueDate(myDate);
t.setHasDate(true);
Intent alarmNotificationIntent = new Intent(this, ReminderNotification.class);
alarmNotificationIntent.putExtra("task", t);
PendingIntent pendingIntent =
PendingIntent.getBroadcast(this, (int) task_id, alarmNotificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(t.getDueDate().getTime());
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
In addition I've created:
NotificationReceiver
import android.app.Activity;
import android.os.Bundle;
public class NotificationReceiver extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
}
ReminderNotification
import android.content.Context;
import android.content.Intent;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
public class ReminderNotification extends BroadcastReceiver
{
public ReminderNotification()
{
// TODO Auto-generated constructor stub
}
#Override
public void onReceive(Context context, Intent intent) {
// The PendingIntent to launch our activity if the user selects this notification
Task task = (Task)intent.getSerializableExtra("task");
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
// Set the info for the views that show in the notification panel.
Intent snzInt = new Intent(context, SnoozeReminderReceiver.class);
snzInt.putExtra("task", task);
PendingIntent snoozeIntent = PendingIntent.getBroadcast(context, 0,snzInt, PendingIntent.FLAG_CANCEL_CURRENT);
Intent doneInt = new Intent(context,DoneActionReceiver.class);
doneInt.putExtra("task", task);
PendingIntent doneIntent = PendingIntent.getBroadcast(context, 0,doneInt, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager notificationManager =
(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
}

I have a feeling that I'm missing something very small but cannot find the issue.
Please let me know what I'm doing wrong.
Thanks in advance.
you have to first build notification and then notify it...
NotificationManager _manager =(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification.Builder(this)
.setContentTitle("New")
.setContentText("hello")
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pintent)
.build();
notification.vibrate=new long[]{100,250,100,500};
_manager.notify(notification_id, notification);
You can find a complete example of Alarm and Notification in my this GitHub Repo
I created a notification setup in my application.when the user clicks the notification an activity Coding is suppose to open.But it isn't.When i checked the phone log(in the console of the android studio) it has some thing like this in it:
10-19 19:18:14.598 888-1437/? W/ActivityManager: Permission Denial: starting Intent { flg=0x1000c000 cmp=com.defcomdevs.invento16/.Coding bnds=[0,874][1080,1060] } from null (pid=-1, uid=10169) not exported from uid 10185
i don't understand what that is?
my code for notification is:
public class AlarmReceiver extends BroadcastReceiver {
static int notifyId=1;
#Override
public void onReceive(Context context, Intent intent) {
//Toast.makeText(context,"Alarm has been set",Toast.LENGTH_SHORT).show();
NotificationCompat.Builder mNotify=new NotificationCompat.Builder(context);
mNotify.setSmallIcon(R.drawable.index);
mNotify.setContentTitle("Coding");
mNotify.setContentText("INVENTO: Coding competition is going to be conducted today.");
Intent resultIntent=new Intent(context,Coding.class); //activity to open up when user clicks the notification
TaskStackBuilder stackBuilder=TaskStackBuilder.create(context);
stackBuilder.addParentStack(Coding.class); //add the to-be-displayed activity to the top of stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
mNotify.setContentIntent(resultPendingIntent);
NotificationManager notificationManager=(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notifyId, mNotify.build());
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(context, notification);
r.play();
//note: on click display activity is not working.
}
}
please help!!

Add android:exported="true" to your .Coding activity tag in the manifest.xmlfile. Though have in mind that this allows other applications to start your activity.
In my App, I'm using AlarmManager for transmitting keep-alive every day once a day.
I'm using the following code for starting athe AlaramManager
Calendar calendar = DateUtils
.getNextKeepAliveTime(keepAliveHours, keepAliveMinutes);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(),
ALARM_REQUEST_CODE, intent, 0); // PendingIntent.FLAG_UPDATE_CURRENT);
// Get the AlarmManager service
Log.d(TAG, "cal: " + calendar.toString());
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
long diff = calendar.getTimeInMillis() - System.currentTimeMillis();
if(diff < 0) diff = AlarmManager.INTERVAL_FIFTEEN_MINUTES;
am.setInexactRepeating(AlarmManager.RTC_WAKEUP, diff, AlarmManager.INTERVAL_DAY, sender);

try {
Toast.makeText(context, "alarm message", Toast.LENGTH_SHORT).show();
MainActivity.instance.sendKeepALive();
} catch (Exception e) {
Toast.makeText(
context,
"There was an error somewhere, but we still received an alarm",
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}
How it can be solved?
Thanks,

Try to remove the code for the broadcast receiver from the Activity ,make another java file and put it there and also modify your manifest as per that
<receiver android:name=".AlarmReceiver" />
instead of
<receiver android:name="MainActivity$AlarmReceiver" android:enabled="true" />
