I want to create a notification without any sounds. How can I do this?Thanks.
This is my code: Link
Excuse me my friends.I could not put my code here.
Thank you so much.
i really do not understand your problem but in simpler terms..this is the code for creating notifications in android:
Notification notifica = new Notification();
notifica.flags |= Notification.FLAG_AUTO_CANCEL;
notifica.icon = R.drawable.serie_notification;
notifica.when = System.currentTimeMillis();
And to disable sound you have to add this:
notifica.defaults = 0;

The way my apk updates currently is through the new apk installing itself over the old one(while not overwriting the local database or settings).
So since Android 10(API 29) ACTION_VIEW was deprecated so this doesn't really work anymore:
Intent intent = new Intent(Intent.ACTION_VIEW);
//output file is the apk downloaded earlier
intent.setDataAndType(Uri.fromFile(outputFile), "application/vnd.android.package-archive");
startActivity(intent);
Following different answers I've found over the internet I need to start using PackageInstaller instead. Looking at the demo found in the Android docs I get to this:
Intent intent = new Intent(PSMentorActivity.this,InstallApkSessionApi.class);
intent.putExtra("apkFile",outputFile);
this.startActivity(intent);
Where InstallApkSessionApi contains a button that when pressed should start the install window:
PackageInstaller packageInstaller = getPackageManager().getPackageInstaller();
PackageInstaller.SessionParams params = new
PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL);
int sessionId = packageInstaller.createSession(params);
session = packageInstaller.openSession(sessionId);
addApkToInstallSession(file, session);
// Create an install status receiver.
Context context = InstallApkSessionApi.this;
Intent intent = new Intent(context, InstallApkSessionApi.class);
intent.setAction(PACKAGE_INSTALLED_ACTION);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
IntentSender statusReceiver = pendingIntent.getIntentSender();
// Commit the session (this will start the installation workflow).
session.commit(statusReceiver);
Simple enough, albeit more complicated compared to the past. The response I get in onNewIntent is always:
case PackageInstaller.STATUS_FAILURE:
Toast.makeText(this, "Install failed!10 " + status + ", " + message,
Toast.LENGTH_SHORT).show();
break;
where the status and message take the following values: status=1, message= "INSTALL_FAILED_INTERNAL_ERROR: Permission denied".
So I assumed it was a problem with permissions. I already had permissions in place over reading and writing to storage. Other related permissions are: INSTALL_PACKAGES and REQUEST_INSTALL_PACKAGES which I cannot use due to the first not being intended for third party uses and the latter being signature level.
Is there something I am terribly missing or is there not a way for me to update my Apk without going through google play?
I've faced the same issue and tried the same way(PackageInstaller) just like you did. It doesn't work.
So, here is a solution for you,
if(android.os.Build.VERSION.SDK_INT >= 29){
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
intent.setData(Uri.fromFile(outputFile));
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}else{
Intent intent = new Intent(Intent.ACTION_VIEW);
//output file is the apk downloaded earlier
intent.setDataAndType(Uri.fromFile(outputFile), "application/vnd.android.package-
archive");
startActivity(intent);
}
I have tested in Android 10 (Google Pixel 2, One+7, Samsung s10) it's working fine. If you are still facing any problem please let me know.
Note: Your version code must be greater than the old one.
So after help and some more searching the great internet, I've been able to make both methods work for me. I still don't really understand what causes the problem. Previously I was creating the Uri used in the intent from the file directly with Uri.fromFile(file). This works for anything under Android 10. The new way I handle this is by using a provider and getting the file using that.
Current method, to be used for a while until I can properly implement PackageManager installation(still have some issues to fix).
Uri urlapk = FileProvider.getUriForFile(this,BuildConfig.APPLICATION_ID+".fileProvider",outputFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(urlapk, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
Using PackageManager just as specified in my question with the following difference (the inputStream is now being build from an Uri):
private void addApkToInstallSession(Uri uri, PackageInstaller.Session session)
throws IOException {
try (OutputStream packageInSession = session.openWrite("package", 0, -1);
InputStream is = getContentResolver().openInputStream(uri)) {
byte[] buffer = new byte[16384];
int n;
while ((n = is.read(buffer)) >= 0) {
packageInSession.write(buffer, 0, n);
}
}
}
The main problem I have with PackageManager is that it closes my app while it installs providing no default feedback to the user. So I guess I will have to "make" that feedback. I will move on to PackageManager as ACTION_VIEW is deprecated for apks.
Am trying to set reply action in push notification like Whatsapp. How to show popup window like whatsapp for replying in push notification.
I have to open a dialog like below image when click of reply.
Direct reply is available on devices with Android N or higher.
First, you need to build remote input, that can be passed into notification builder.
RemoteInput remoteInput = new RemoteInput.Builder(KEY_INLINE_REPLY)
.setLabel("Response")
.build();
Then you can create your notification
NotificationCompat.Action replyAction =
new NotificationCompat.Action.Builder(android.R.drawable.ic_custom_icon,"Respond", respondPendingIntent)
.addRemoteInput(remoteInput)
.build();
nofitication.addAction(replyAction);
Next, we need to retrieve the input. In the component started by the pending intent (e.g. an Activity or Service), the remote input is available on the Intent. The user’s input is accessed using the same key that was used when building the remote input:
Bundle remoteInput = RemoteInput.getResultsFromIntent(intent);
if (remoteInput != null) {
CharSequence reply = remoteInput.getCharSequence(KEY_INLINE_REPLY);
//do something awesome with the reply
}
After the reply has been entered, a progress spinner is displayed to indicate that something is happening. It is up to you to stop the spinner, once the reply has been processed. There are at least a couple of ways to handle this:
Cancel the notification by calling cancel
Re-issue the notification, and include an updated message (e.g. “Successful reply”)
You should add backwards compatibility
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//we are running Nougat
respondIntent = new Intent(context, NotificationIntentService.class);
respondPendingIntent = PendingIntent.getService(context, 0, respondIntent, PendingIntent.FLAG_CANCEL_CURRENT);
} else {
//we are running a version prior to Nougat
respondIntent = new Intent(context, MainActivity.class);
respondPendingIntent = PendingIntent.getActivity(context, 0, respondIntent, PendingIntent.FLAG_CANCEL_CURRENT);
}

I'm currently working on a alarm app that plays a random alarm tone. I've been able to load a ringtone from the ringtone dialog but I'm thinking of loading a random ringtone directly from the ringtone directory. How would I go about accomplishing this?
You can query for available ringtones in the device:
RingtoneManager ringtoneMgr = new RingtoneManager(this);
ringtoneMgr.setType(RingtoneManager.TYPE_ALARM);
Cursor alCursor = ringtoneMgr.getCursor();
This alCursor will contain the available ringtone URIs. Now iterate through them & build a URI array:
Uri[] alarms = new Uri[alCursor.getCount()];
while(alCursor.moveToNext()) {
int pos = alCursor.getPosition();
alarms[pos] = ringtoneMgr.getRingtoneUri(pos);
}
alCursor.close();
Now, just generate a random number in the range of 0-alCursor.getCount(), take that ringtone from alarms array & play it.
Random r = new Random();
int randNum = r.nextInt(alCursor.getCount());
Ringtone ringtone = RingtoneManager.getRingtone(this, alarms[randNum]);
ringtone.play();
This can be an easy approach to achieve your goal. Hope it helps. Thanks.
I am working on a android news app which gets news from google news rss feed. I am currently getting news and showing it to the user in my app. But I want to show notification to the user when new news appears on google rss. I have no idea how to do it as I am new to android and could not find anything relevant on google. Thank you.
Here is my code I have done so far
internal static List<FeedItem> GetFeedItems(string url)
{
List<FeedItem> feedItemsList = new List<FeedItem>();
try
{
HttpClient wc = new HttpClient();
var html = wc.GetStringAsync(new Uri(url)).Result;
XElement xmlitems = XElement.Parse(html);
// We need to create a list of the elements
List<XElement> elements = xmlitems.Descendants("item").ToList();
// Now we're putting the informations that we got in our ListBox in the XAML code
// we have to use a foreach statment to be able to read all the elements
// Description , Link , Title are the attributes in the RSSItem class that I've already added
List<FeedItem> aux = new List<FeedItem>();
foreach (XElement rssItem in elements)
{
FeedItem rss = new FeedItem();
rss.Description = rssItem.Element("description").Value;
rss.Link = rssItem.Element("link").Value;
rss.Title = rssItem.Element("title").Value;
feedItemsList.Add(rss);
}
}
catch (Exception)
{
throw;
}
return feedItemsList;
}
Use parse's push notification,it's very easy to use and has great documents.
https://parse.com
go for push notification service. its the only way to get the notification .
follow this tutorial... http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/
Notification manager is what you want here.
see this http://developer.android.com/guide/topics/ui/notifiers/notifications.html ?
A simple google search also shows tutorials for the same
So my android application detects when location changes and then it notifies the user and makes him take action either call a number or send SMS.
The SMS is sent to a saved number and its body is "I'm at " + fullAddress
private NotificationCompat.Builder buildNormal(CharSequence pTitle,String fullAddress) {
NotificationCompat.Builder builder = new NotificationCompat.Builder(
this);
Intent in = new Intent(this,MainActivity.class);
PendingIntent pMainIntent = PendingIntent.getActivity(this, 0,
in, 0);
if(getSavedDataString("gNumber")!=null)
{
String url = getSavedDataString("gNumber");
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(url));
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
//Intent smsIntent = new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:"
//+ Uri.encode(getSavedDataString("gNumber").substring(4))));
//intent.setData());
//startActivity(intent);
Intent smsIntent = new Intent(Intent.ACTION_VIEW);
//smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address", getSavedDataString("gNumber").substring(4));
smsIntent.putExtra("sms_body","I'm at " + fullAddress);
smsIntent.setData(Uri.parse("smsto:"
+ Uri.encode(getSavedDataString("gNumber").substring(4))));
PendingIntent psmsIntent = PendingIntent.getActivity(this, 0,
smsIntent, 0);
builder.addAction(android.R.drawable.ic_menu_call, "Call", pIntent);
builder.addAction(android.R.drawable.sym_action_email, "Send SMS", psmsIntent);
}
else
{
builder.addAction(0, "Choose Guardian", pMainIntent);
}
builder.setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL);
// set the shown date
builder.setWhen(System.currentTimeMillis());
// the title of the notification
builder.setContentTitle(pTitle);
// set the text for pre API 16 devices
builder.setContentText(pTitle);
// set the action for clicking the notification
builder.setContentIntent(pMainIntent);
// set the notifications icon
builder.setSmallIcon(R.drawable.ic_home);
//builder.setSound(android.)
// set the small ticker text which runs in the tray for a few seconds
builder.setTicker("Location Change Alert");
// set the priority for API 16 devices
//builder.setVibrate(pattern)
builder.setPriority(Notification.PRIORITY_DEFAULT);
return builder;
}
it shows here that the notification that shows to the user contains 2 actions to call or to send message and it sends it to the presaved number gNumber
The problem is after i press the action to send sms and then discard that message without sending it also deleting it from draft and all that.
and then the app detects another location change so it sends a different notification with different fullAddress the intent is still stuck at the same text body!!
I also tried to change the recipient and it gets stuck on the old recipient too. I have to either restart the device or send the message I once discarded.
I also tried to change from ACTION_VIEW to ACTION_SEND or ACTION_SENDTO but all in vain.
I want to know if there's a solution to this intent getting stuck on the same body and recipient other than changing this intent totally and using SMSManager
Help please.
When your app requests a PendingIntent, the system keeps a token on behalf of your app to perform an action as though your app is actually doing it. It is done this way so that, even if your app is killed, whatever process receives the PendingIntent can still follow through with it.
When these tokens are created, certain info is recorded, e.g. the operation, the the action, etc. If your app were to request another PendingIntent with the same info, the same token will be returned. Now, the info used to determine if they are the same or different does not include the extras that the Intent itself carries. So when your app requests the same SMS operation with only different Intent extras, you're going to get the same token with the original extras over and over again, unless you pass a flag to indicate differently.
As for the difference between the flags: FLAG_CANCEL_CURRENT "ensures that only entities given the new data will be able to launch it. If this assurance is not an issue, consider FLAG_UPDATE_CURRENT." In your case, I don't think this is an issue, so FLAG_UPDATE_CURRENT should be sufficient. If it is a concern, use FLAG_CANCEL_CURRENT.
