I'm stuck in a creation of a notification..Just want display the battery level in the status bar(notifications bar)The notification has been permanent. This is part of code:
private BroadcastReceiver batteryInfoReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
int level= intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
String[] status = {
"Level: "+level
. . .
};
NotificationManager notifi = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,"Level",System.currentTimeMillis());
notification.flags = Notification.FLAG_ONGOING_EVENT;
Intent i = new Intent(context, MainActivity.class);
PendingIntent penInt = PendingIntent.getActivity(getApplicationContext(), 0 , i , 0);
notification.setLatestEventInfo(getApplicationContext(), +level+"%", penInt);
notifi.notify(215,notification);
}
};
Is it correct? Is there something else to add for example in the manifest? I don't have a specified class for the notification so i wrote in this way this line: Intent i = new Intent(context, MainActivity.class); but i don't know if it's correct.
Yes, you need to add :
<uses-permission android:name="android.permission.BATTERY_STATS" />

I'm delivering a notification which has 2 action buttons namely "Accept" and "Reject".
I'm following this Github repo.
When user clicks "Accept", certain conditions are checked and the logic is performed accordingly.
UPDATE 2.0 - The problem is that upon clicking "Accept" button, operation is happening successfully but the notification isn't disappearing from the status bar because the id generating here: m = (new Random()).nextInt(10000); is different from here: actionIntent.putExtra("id", NotificationARBroadcastReceiver.m); every single time!
Here's the code for notification:
Intent notificationIntent = new Intent(getBaseContext(), NotificationARBroadcastReceiver.class);
notificationIntent.putExtra(NotificationARBroadcastReceiver.NOTIFICATION, getNotificationNewRequestService());
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), m, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 0, pendingIntent);
Here's getNotificationNewRequestService():
private Notification getNotificationNewRequestService() {
mBuilder =
new NotificationCompat.Builder(getBaseContext())
.setSmallIcon(R.mipmap.app_icon_1)
.setContentTitle("Title")
.setContentText("text...");
Intent resultIntent = new Intent(getBaseContext(), Profile.class);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
getBaseContext(),
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
// for action button
Intent actionIntent = new Intent(getBaseContext(), MyBroadcastSender.class);
actionIntent.putExtra("id", NotificationARBroadcastReceiver.m);
PendingIntent actionPendingIntent = PendingIntent
.getBroadcast(getBaseContext(),
0, actionIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setAutoCancel(true);
mBuilder.setContentIntent(resultPendingIntent);
mBuilder.addAction(R.drawable.ic_accepted_request_black_24dp, "Accept", actionPendingIntent);
mBuilder.addAction(R.drawable.ic_close_black_24dp, "Reject", null);
return mBuilder.build();
}
Here's NotificationARBroadcastReceiver.java file:
public class NotificationARBroadcastReceiver extends BroadcastReceiver {
public static String NOTIFICATION = "notification";
public static NotificationManager mNotifyMgr;
public static int m;
#Override
public void onReceive(Context context, Intent intent) {
m = (new Random()).nextInt(10000);
Log.d("mMain", String.valueOf(m));
mNotifyMgr =
(NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
Notification notification = intent.getParcelableExtra(NOTIFICATION);
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_VIBRATE;
mNotifyMgr.notify(m, notification);
}
}
Here's MyBroadcastSender.java file:
public class MyBroadcastSender extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Broadcast Received by MyBroadcastSender.", Toast.LENGTH_SHORT).show();
int id = intent.getIntExtra("id", 1);
// send back to your class
Intent newIntent = new Intent();
newIntent.setAction(context.getString(R.string.broadcast_id));
newIntent.putExtra("id1", id);
context.sendBroadcast(newIntent);
context.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
Toast.makeText(context, "Broadcast sent back.", Toast.LENGTH_SHORT).show();
}
}
and here's MyBroadcastReceiver.java file:
// BroadcastReceiver
public class MyBroadcastReceiver extends BroadcastReceiver {
public MyBroadcastReceiver(){
super();
}
#Override public void onReceive(Context context, Intent intent) {
int id2 = intent.getIntExtra("id1", 1);
if (intent.getAction() != null && intent.getAction().equals(getString(R.string.broadcast_id))) {
NotificationARBroadcastReceiver.mNotifyMgr.cancel(id2);
Intent intent1 = new Intent(MyService.this, MainActivity.class);
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent1);
Toast.makeText(context, "Broadcast received by MyBroadcastReceiver. Now, you can perform actions.",
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Intent is null.", Toast.LENGTH_SHORT).show();
}
}
}
In getNotificationNewRequestService(), I'm putting notification id as an extra in "id", then in MyBroadcastSender.java, I'm getting this extra as int id = intent.getIntExtra("id", 1); and then putting again as newIntent.putExtra("id1", id); and then finally getting it in MyBroadcastReceiver.java as int id2 = intent.getIntExtra("id1", 1); and trying to remove the notification using it as NotificationARBroadcastReceiver.mNotifyMgr.cancel(id2);.
Sorry for this much code, I've to upload it all as they all are necessary.
What I want is to know how to deliver the same notification id from NotificationARBroadcastReceiver.java (which is a separate java file) to MyBroadcastReceiver(which is an inner class in MyService.java)?
Update 1.0- this is what happened when I printed out the values of m, mMain, id, id1:
D/m: 0
D/mMain: 9994
D/id: 0
D/id1: 0
Assuming getNotificationService() == getNotificationNewRequestService() Looks like the NotificationARBroadcastReceiver isn't called before the notfication is built and displayed.
You would do better to generate the notification id where you create the notification and just add it to the intent there as well you don't need to make.
So call getNotificationNewRequestService() from NotificationARBroadcastReceiver.recieve() and make sure the notification ids match up.
Edit:
move:
m = (new Random()).nextInt(10000);
before:
actionIntent.putExtra("id", NotificationARBroadcastReceiver.m); // this will be 'm'
Result:
int m = (new Random()).nextInt(10000);
Intent actionIntent = new Intent(getBaseContext(), MyBroadcastSender.class);
actionIntent.putExtra("id", m);
Log.d(getClass().getSimpleName(), "Notification Id is : " + m);
then, you can check what values are in id, id1 and id2. Don't forget to call .notify() with same Id you got from m.
You can, also, create getRandomNotificationId() and getLastGeneratedNotificationId() methods. Whenever you generate an Id, store it in public static integer variable, so that you can access it throughout the class.
Problem might be that you are accessing m from NotificationARBroadcastReceiver before initializing it. So, it will definitely be 0. And, you mentioned something about println error, are you using System.out.println()?
Before Edit:
As seen on your new edit, try closing notification before starting it:
m = (...);
// some code here
mNotifyMgr.cancel(m);
mNotifyMgr.notify(m, notification);
and see if your issue gets resolved.
how to set notification with play/pause, next and previous button in android.!
I am new with Android & also at stack overflow. So please bear with me.
I set notification when song is start to play like below :
`
#SuppressLint("NewApi")
public void setNotification(String songName){
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager notificationManager = (NotificationManager) getSystemService(ns);
#SuppressWarnings("deprecation")
Notification notification = new Notification(R.drawable.god_img, null, System.currentTimeMillis());
RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.notification_mediacontroller);
//the intent that is started when the notification is clicked (works)
Intent notificationIntent = new Intent(this, AudioBookListActivity.class);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.contentView = notificationView;
notification.contentIntent = pendingNotificationIntent;
notification.flags |= Notification.FLAG_NO_CLEAR;
//this is the intent that is supposed to be called when the button is clicked
Intent switchIntent = new Intent(this, AudioPlayerBroadcastReceiver.class);
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, switchIntent, 0);
notificationView.setOnClickPendingIntent(R.id.btn_play_pause_in_notification, pendingSwitchIntent);
notificationManager.notify(1, notification);
}
`
I have create BroadcastReceiver like below :
`
private class AudioPlayerBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
System.out.println("intent action = " + action);
long id = intent.getLongExtra("id", -1);
if(Constant.PLAY_ALBUM.equals(action)) {
//playAlbum(id);
} else if(Constant.QUEUE_ALBUM.equals(action)) {
//queueAlbum(id);
} else if(Constant.PLAY_TRACK.equals(action)) {
//playTrack(id);
} else if(Constant.QUEUE_TRACK.equals(action)) {
//queueTrack(id);
} else if(Constant.PLAY_PAUSE_TRACK.equals(action)) {
// playPauseTrack();
System.out.println("press play");
} else if(Constant.HIDE_PLAYER.equals(action)) {
// hideNotification();
System.out.println("press next");
}
else {
}
}
}`
Now, I set custom notification successfully but how can i handle notification buttons and its events like play/pause, previous and next... etc. I also try using broadcast receiver but could not get any response.
Seeking solution and guidance from experts, please help me out.
Thanks in advance.
You need to set a custom intent action, not the AudioPlayerBroadcastReceiver component class.
Create a Intent with custom action name like this
Intent switchIntent = new Intent("com.example.app.ACTION_PLAY");
Then, register the PendingIntent Broadcast receiver
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 100, switchIntent, 0);
Then, set a onClick for the play control , do similar custom action for other controls if required.
notificationView.setOnClickPendingIntent(R.id.btn_play_pause_in_notification, pendingSwitchIntent);
Next,Register the custom action in AudioPlayerBroadcastReceiver like this
<receiver android:name="com.example.app.AudioPlayerBroadcastReceiver" >
<intent-filter>
<action android:name="com.example.app.ACTION_PLAY" />
</intent-filter>
</receiver>
Finally, when play is clicked on Notification RemoteViews layout, you will receive the play action by the BroadcastReceiver
public class AudioPlayerBroadcastReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equalsIgnoreCase("com.example.app.ACTION_PLAY")){
// do your stuff to play action;
}
}
}
EDIT: how to set the intent filter for Broadcast receiver registered in code
You can also set the Custom Action through Intent filter from code for the registered Broadcast receiver like this
// instance of custom broadcast receiver
CustomReceiver broadcastReceiver = new CustomReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
// set the custom action
intentFilter.addAction("com.example.app.ACTION_PLAY");
// register the receiver
registerReceiver(broadcastReceiver, intentFilter);
Is possible create a permanent notification of battery level starting from this code?:
public void onCreate(Bundle savedInstanceState) {
...
this.registerReceiver(this.myBatteryReceiver , new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
...
}
private BroadcastReceiver myBatteryReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);
//here you can use level as you wish.
}
};
And this is an example of a notification.
private void CheckNoti(){
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
service.this);
notificationBuilder.setContentTitle("Title");
notificationBuilder.setContentText("Context");
notificationBuilder.setTicker("TickerText");
notificationBuilder.setWhen(System.currentTimeMillis());
notificationBuilder.setSmallIcon(R.drawable.ic_stat_icon);
Intent notificationIntent = new Intent(this, service.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
notificationBuilder.setContentIntent(contentIntent);
notificationBuilder.setDefaults(Notification.DEFAULT_SOUND
| Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE);
mNotificationManager.notify(1,
notificationBuilder.build());
} }
I have to create a permanent notification with the battery level if possible. How can i do it?
Use the ongoing flags : http://developer.android.com/reference/android/app/Notification.Builder.html#setOngoing%28boolean%29
The user will not be able to cancel the notification so please don't forget to remove it when it's not useful anymore.
For toggle in it, you need to add a PreferenceActivity or a PreferenceFragment to your app. Then add a checkboxPreference : http://developer.android.com/guide/topics/ui/settings.html
In your code, you can now toggle this particular setting :
boolean permanent = PreferenceManager.getDefaultSharedPreferences(context).getBoolean("permanent", false);
if(permanent) {
notificationBuilder.setOngoing(true);
}
I have an action to Dial a number via
uri = Uri.parse("tel:" + address);
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(uri);
PendingIntent pd = PendingIntent.getActivity(context, 0,intent,
PendingIntent.FLAG_UPDATE_CURRENT);
notif.addAction(R.drawable.ic_menu_call, "Call", pd);
but the problem is that I don't know
how/when to call the NotificationManager's manager.cancel() function
so as to dismiss the notification when the call action is clicked!
I had the same situation and I managed to solve it by creating a broadcast receiver that is called when the action button is pressed. The broadcast receiver then receives an intent with the notification id that you want to dismiss and the number you want to dial.
The is the code that creates the notification:
NotificationManager notificationManager =
(NotificationManager)MyApplication.getAppContext().getSystemService(Context.NOTIFICATION_SERVICE);
//for some versions of android you may need to create a channel with the id you want
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel chan = new NotificationChannel("your_channel_id", "ChannelName", NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(chan);
}
Intent intent = new Intent(MyApplication.getAppContext(), ActionReciever.class);
intent.putExtra("phoNo", phoneNumber);
// num is the notification id
intent.putExtra("id", num);
PendingIntent myPendingIntent = PendingIntent.getBroadcast(
MyApplication.getAppContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT
);
Notification n = new NotificationCompat.Builder(MyApplication.getAppContext(),
"your_channel_id")
.setSmallIcon(R.drawable.app_pic)
.addAction(R.drawable.app_pic, "Dial now", myPendingIntent)
.setAutoCancel(true)
.build();
notificationManager.notify(num, n);
This is the broadcast receiver code, it is called when the action button is pressed. The received intent here is the intent inside the pending intent we prepared in the notification:
public class ActionReciever extends BroadcastReceiver {
#SuppressLint("MissingPermission")
#Override
public void onReceive(Context context, Intent intent) {
String phoneNumber = intent.getStringExtra("phoNo");
int id = intent.getIntExtra("id",0);
Intent i = new Intent(Intent.ACTION_DIAL);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.setData(Uri.parse("tel:" + phoneNumber));
NotificationManager notificationManager =
(NotificationManager) MyApplication.getAppContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(id);
context.startActivity(i);
}
}
Register the BroadcastReceiver in the app manifest inside application tag
<receiver android:name=".ActionReciever" />
MyApplication is a class that extends the default Application so I can have a place to store the context I need.
public class MyApplication extends Application {
private static Context context;
public void onCreate() {
super.onCreate();
MyApplication.context = getApplicationContext();
}
public static Context getAppContext() {
return MyApplication.context;
}
}
Note that you need to update the manifest to run the MyApplication class like this:
android:name="com.example.yourpackage.MyApplication"
This code works even if the app is down and without a background service.
See Android READ PHONE STATE? - about phone state.
case TelephonyManager.CALL_STATE_RINGING:
notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(100); // cancel notification by ID
break;
// build your notification.
intent notificationIntent = new Intent(context,
YourPhoneActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
Bitmap bm = BitmapFactory.decodeResource(context.getResources(),
iconLarge);
NotificationCompat.Builder builder = new NotificationCompat.Builder(
context).setSmallIcon(iconSmall).setLargeIcon(bm)
.setContentTitle(title).setContentText(message)
.setAutoCancel(false).setContentIntent(intent).setWhen(when)
.setTicker(message);
builder.getNotification();
Is there any way in Android to detect when a user swipes a notification to the left and deletes it? I'm using an alarmmanager to set a repeating alert and I need my repeating alert to stop when the notification is cancelled by the user. Here's my code:
Setting the repeating alert:
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), repeatFrequency, displayIntent);
My notification code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Get the notification ID.
int notifID = getIntent().getExtras().getInt("Reminder_Primary_Key");
//Get the name of the reminder.
String reminderName = getIntent().getExtras().getString("Reminder_Name");
//PendingIntent stores the Activity that should be launched when the user taps the notification.
Intent i = new Intent(this, ViewLocalRemindersDetail.class);
i.putExtra("NotifID", notifID);
i.putExtra("notification_tap", true);
//Add FLAG_ACTIVITY_NEW_TASK to stop the intent from being launched when the notification is triggered.
PendingIntent displayIntent = PendingIntent.getActivity(this, notifID, i, Intent.FLAG_ACTIVITY_NEW_TASK);
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notif = new Notification(R.drawable.flag_red_large, reminderName, System.currentTimeMillis());
CharSequence from = "Here's your reminder:";
CharSequence message = reminderName;
notif.setLatestEventInfo(this, from, message, displayIntent);
//Pause for 100ms, vibrate for 250ms, pause for 100ms, and vibrate for 500ms.
notif.defaults |= Notification.DEFAULT_SOUND;
notif.vibrate = new long[] { 100, 250, 100, 500 };
nm.notify(notifID, notif);
//Destroy the activity/notification.
finish();
}
I know I need to call alarmManager.cancel(displayIntent) in order to cancel my repeating alarm. However, I don't understand where to put this code. I need to cancel the repeating alert ONLY when the user has tapped on the notification or dismissed it. Thanks for your help!
I believe that Notification.deleteIntent is what you are looking for. The doc says:
The intent to execute when the notification is explicitly dismissed by the user, either with the "Clear All" button or by swiping it away individually. This probably shouldn't be launching an activity since several of those will be sent at the same time.
To all those future people out there -- you can register a broadcast receiver to listen for notification delete inents.
Create a new broadcast receiver:
public class NotificationBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action == null || !action.equals(Config.NotificationDeleteAction)) {
return;
}
// Do some sweet stuff
int x = 1;
}
}
Register the broadcast receiver within your application class:
"If your app targets API level 26 or higher, you cannot use the manifest to declare a receiver for most implicit broadcasts (broadcasts that do not target your app specifically)."
Android Documentation.
registerReceiver(
new NotificationBroadcastReceiver(),
new IntentFilter(Config.NotificationDeleteAction)
);
You probably noticed the static variable Config.NotificationDeleteAction. This is a unique string identifier for your notification. It typically follows the following {namespace}{actionName} convention:
you.application.namespace.NOTIFICATION_DELETE
Set the delete intent on your notification builder:
notificationBuilder
...
.setDeleteIntent(createDeleteIntent())
...
Where, createDeleteIntent is the following method:
private PendingIntent createDeleteIntent() {
Intent intent = new Intent();
intent.setAction(Config.NotificationDeleteAction);
return PendingIntent.getBroadcast(
context,
0,
intent,
PendingIntent.FLAG_ONE_SHOT
);
}
Your registered broadcast receiver should receive the intent when your notification is dismissed.
You can also use an Activity PendingIntent, which may be simpler to implement if you have an Activity that can handle the dismissal, because you don't have to create and configure a broadcast receiver.
public static final String DELETE_TAG = "DELETE_TAG";
private PendingIntent createDeleteIntent(Context context) {
Intent intent = new Intent(context, MyActivity.class);
intent.putExtra(DELETE_TAG, true);
return PendingIntent.getActivity(
context,
0,
intent,
PendingIntent.FLAG_ONE_SHOT
);
}
MyActivity would receive the intent in its onCreate(), and in this example, could look for the DELETE_TAG extra to recognize it.
