Send notification to user when new news article appears - java

I have a news article app that has a gridview of all articles then you can select the full article. I want the user to receive a notification when a new news article has been posted. It just has to be really simple, the app logo and some text 'new article posted!' and then when they click on the notification the app is opened. Here is my code below, i'm not sure what you need to see though so let me know if you need anything else.
MainActivity.java
public class MainActivity extends AppCompatActivity {
private List<NewsRecord> newsListData = new ArrayList<NewsRecord>();
private GridView newsListView;
private NewsListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView newsListView = (GridView) findViewById(R.id.newsFeedList);
adapter = new NewsListAdapter(this, R.layout.adapter_news_list, newsListData, this);
newsListView.setAdapter(adapter);
newsListView.setOnItemClickListener(itemClicked);
nextStart = 0;
updateListData(nextStart, 20);
}
public int nextStart = 0;
public void updateListData(int StartPoint, int count){
String url = "http://www.efstratiou.info/projects/newsfeed/getList.php?start=" + StartPoint + "&count=" + count;
EDANewsApp app = EDANewsApp.getInstance();
JsonArrayRequest jsonRequest = new JsonArrayRequest(url, listener, errorListener);
app.requestQueue.add(jsonRequest);
nextStart +=count;
}
#Override
public boolean onCreateOptionsMenu (Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case R.id.action_about:
Intent intent = new Intent(this, AboutActivity.class);
startActivity(intent);
return true;
case R.id.action_search:
return true;
case R.id.action_settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
AdapterView.OnItemClickListener itemClicked = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(MainActivity.this, NewsItemActivity.class);
intent.putExtra("newsItemId", newsListData.get(position).recordId);
startActivity(intent);
}
};
//Listeners
Response.Listener<JSONArray> listener = new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
//we successfully received the JSONArray
//Here we will extract the data and use it in our app
//Clear the dataset before loading new data
// newsListData.clear();
//Go through all the JSON objects
for (int i = 0; i < response.length(); i++) {
try {
//Get one JSON object
JSONObject jsonObj = response.getJSONObject(i);
//Put JSON data in a Java object
NewsRecord record = new NewsRecord();
record.recordId = jsonObj.getInt("record_id");
record.title = jsonObj.getString("title");
record.date = jsonObj.getString("date");
record.shortInfo = jsonObj.getString("short_info");
record.imageUrl = jsonObj.getString("image_url");
newsListData.add(record);
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter.notifyDataSetChanged();
}
};
Response.ErrorListener errorListener = new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//There was an error in the communication
//We can notify the user about it
}
};
}

I am not 100% sure about when new article is posted.
If I am right, after adapter.notifyDataSetChanged() notify user with notificatoins by below code:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!");
// Replace ResultActivity.class to your result notification class.
Intent resultIntent = new Intent(this, ResultActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// first element (0) allows you to update the notification later on.
mNotificationManager.notify(0, mBuilder.build());

Does Service needs another parser?

I have already been fetched data from instagram api. But i cannot reach that data to use it on my service. I have tried all methods that i know.
**Here is my main object: ** If my followers count is increases or decreases, notify, And check that for every 5 min.(I am still working on it. There are lots of misses yet.)
**Here is my main question: ** Do i really have to create a new parser to fetch data that i already have or what should i build?
If you have any sample or Articles for this case, that would be useful.
I heard about Csv file. Is that can be useful to import ?
PS: I learned java and android studio yet. I am pretty newbie.

The only solution that i found is the adding parser to your service to reach data from api. None of the the method can access to reach data from service to activity.
I added this class to reach api data on service.
public void lilParser() throws IOException, JSONException{
URL url = new URL(API_URL + "/users/" + mSession.getId()
+ "/?access_token=" + mAccessToken);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoInput(true);
urlConnection.connect();
String response = Utils.streamToString(urlConnection
.getInputStream());
System.out.println(response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
JSONObject data_obj = jsonObj.getJSONObject("data");
JSONObject counts_obj = data_obj.getJSONObject("counts");
String name = jsonObj.getJSONObject("data").getString("full_name");
String bio =jsonObj.getJSONObject("data").getString("bio");
String counts=jsonObj.getJSONObject("data").getString("counts");
userInfoHashmap.put(TAG_FOLLOWED_BY,counts_obj.getString(TAG_FOLLOWED_BY));
Log.i(TAG,"followedby=>[" + counts + "]");
}
And, Here is my onCreate. You can check The data if it is changed or not.
#Override
public void onCreate() {
Toast.makeText(this,"Service Started", Toast.LENGTH_LONG).show();
myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
String fo = userInfoHashmap.get(TAG_FOLLOWED_BY);
try {
lilParser();
}
catch (IOException e) {e.printStackTrace();}
catch (JSONException e) {e.printStackTrace();}
if(new String(userInfoHashmap.get(TAG_FOLLOWED_BY)).equals(fo)==true){}
else {
getnotification();
}
}
}, 0, 30000);
}
PS: I published my code, that may help someone else. I am still newbie.

Cant find a way to work with Alarm manager in taskAdapter

My question is simple, I have made a bit of a mess in my TaskAdapter and now I am facing a problem with an onCreate method because I dont have it in my TaskAdapter (obviously).
Now if You could give Me some ideas on how to implement my alarmManager and link the ALARM_SERVICE so the code would work.
Heres my BaseAdapter:
'public class TaskAdapter extends BaseAdapter {
//transfer context
Context context;
//transfer user to use for shared preferences
String userName;
//create a list of tasks.....
List<taskItem> myTasks;
Calendar calendar = Calendar.getInstance();
AlarmManager alarmManager;
PendingIntent pendingIntent;
//constructor, for creating the adapter we need from the user context and userName
public TaskAdapter(Context context, String userName) {
this.context = context;
this.userName = userName;
//go to user shared preferences and fill the list
getData();
notifyDataSetChanged();
}
//how many item to display
#Override
public int getCount() {
//return the myTasks size....
return myTasks.size();
}
//return a specific item by index
#Override
public Object getItem(int i) {
return myTasks.get(i);
}
//return index number
#Override
public long getItemId(int i) {
return 0;
}
//create our view
#Override
public View getView(final int index, final View view, ViewGroup viewGroup) {
//inflate the view inside view object -> viewInflated
final View viewInflated = LayoutInflater.from(context).inflate(R.layout.task_item, null, false);
//set our inflated view behavior
//set pointer for our inflated view
//set pointer for task name....
final TextView txtTaskName = (TextView) viewInflated.findViewById(R.id.taskName);
//set pointer for taskInfo
final TextView txtTaskInfo = (TextView) viewInflated.findViewById(R.id.taskInfo);
//set pointer for task status....
final Switch swTask = (Switch) viewInflated.findViewById(taskDone);
//set task name, by the index of my myTasks collection
txtTaskName.setText(myTasks.get(index).taskName);
//set task info, by index of myTasks collection
txtTaskInfo.setText(myTasks.get(index).taskInfo);
//set task status , switch is getting true/false
swTask.setChecked(myTasks.get(index).taskStatus);
//show date and time dialog
final ImageView dtPicker = (ImageView) viewInflated.findViewById(R.id.imgTime);
dtPicker.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final AlertDialog.Builder ad = new AlertDialog.Builder(context);
final AlertDialog aDialog = ad.create();
final LinearLayout adLayout = new LinearLayout(context);
adLayout.setOrientation(LinearLayout.VERTICAL);
TextView txtTime = new TextView(context);
txtTime.setText("Choose time");
adLayout.addView(txtTime);
final TimePicker tp = new TimePicker(context);
adLayout.addView(tp);
final DatePicker dp = new DatePicker(context);
tp.setVisibility(View.GONE);
adLayout.addView(dp);
final Button btnNext = new Button(context);
btnNext.setText("Next>");
adLayout.addView(btnNext);
btnNext.setGravity(1);
Button btnCancel = new Button(context);
btnCancel.setText("Cancel");
adLayout.addView(btnCancel);
btnCancel.setGravity(1);
btnCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {

}
});
btnNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

final int min = tp.getMinute();
final String myHour = String.valueOf(hour);
final String myMin = String.valueOf(min);

//get all tasks from shared preferances
//the shared preferences is by key and value, therefor we will use Map collection
//we know that the key is String, but we don't know what type of value we will get. <K,?>
Map<String, ?> tasks = taskPref.getAll();
// transfer the data from map collection to list collection , single item is like the defination of the tasks <String,?>
//Entry -> record , enterSet -> set of records
for (Map.Entry<String, ?> oneTask : tasks.entrySet()) {
//insert task to list by Key and Value, we check if value is equal to 1, becuase 1=true 0=false
String[] str = oneTask.getValue().toString().split(",");
myTasks.add(new taskItem(str[0], str[1], str[2].equals("1")));
}
}
}'
I cant find a way to start
"alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE)" because I dont really know how to start it in an other way if there is a way.
Any help would be much appreciated!
Here is my AlarmReceiver:
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.e("Didnt start alarm", "Too bad...");
Intent service_intent = new Intent(context, RingtonePlayingService.class);
context.startService(service_intent);
}
}
And here is the RingtoneService:
public class RingtonePlayingService extends Service {
MediaPlayer someMedia;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Log.i("Local Services", "Received start id "+ startId+": "+intent);
someMedia = MediaPlayer.create(this, R.raw.skyrim);
someMedia.start();
return START_NOT_STICKY;
}
#Override
public void onDestroy()
{
Toast.makeText(this, "On destroy called!", Toast.LENGTH_SHORT).show();
}
}
Cheers.
It looks like your alarmManager field isn't being initialized.
Add this line to your TaskAdapter constructor:
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Also, you can directly call your service, no need for the BroadcastReceiver in the middle:
Intent my_intent = new Intent(context, RingtonePlayingService.class);
pendingIntent = PendingIntent.getService(context, 0, my_intent, PendingIntent.FLAG_UPDATE_CURRENT);
UPDATE
A service should be declared with the service tag in the manifest.
See: https://developer.android.com/guide/topics/manifest/service-element.html
<service android:name=".RingtonePlayingService" android:enabled="true"/>

I tried this way and this code is not displaying the notification on Button Click...
May be that's because you are trying to add
taskadd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
addtask=taskname.getText().toString();
adddetail=taskdetail.getText().toString();
adddate= taskdate.getText().toString();
InsertData();
Notification();
}
});
inside onClick() of your fragment. Since you are already inside onClick() you will not be requiring taskadd.setOnClickListener().
Instead replace your onClick() method with this.
if(view == taskadd) {
fromDatePickerDialog.show();
}
addtask=taskname.getText().toString();
adddetail=taskdetail.getText().toString();
adddate= taskdate.getText().toString();
InsertData();
Notification();
try this code to generate small and big notifications

#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), PushNotificationDemo.class);
final PendingIntent pending = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
NotificationManager notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
Notification n;
switch (v.getId()) {
case R.id.nd_smallnotification:
if (heading.getText().length() <= 0) {
heading.setError("Please provide push notification title");
} else {
heading.setError(null);
heading_text = heading.getText().toString();
n = new NotificationCompat.Builder(this)
.setContentTitle(heading_text)
.setContentText(message.getText().toString())
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pending)
.setDefaults(Notification.DEFAULT_SOUND)
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.addAction(android.R.drawable.ic_menu_manage, "Close", pending)
.build();
n.flags |= Notification.FLAG_AUTO_CANCEL | Intent.FLAG_ACTIVITY_SINGLE_TOP;
notificationManager.notify(0, n);
}
break;
case R.id.nd_bignotification:
if (heading.getText().length() <= 0) {
heading.setError("Please provide push notification title");
} else {
heading.setError(null);
heading_text = heading.getText().toString();
NotificationCompat.InboxStyle nc =
new NotificationCompat.InboxStyle();
nc.setBigContentTitle(heading_text);
String[] text = new String[5];
for (int i = 0; i < 5; i++) {
text[i] = i + ". say hello...";
nc.addLine(text[i]);
}
n = new NotificationCompat.Builder(this)
.setStyle(nc)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pending)
.setDefaults(Notification.DEFAULT_SOUND)
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.build();
n.flags |= Notification.FLAG_AUTO_CANCEL | Intent.FLAG_ACTIVITY_SINGLE_TOP;
notificationManager.notify(100, n);
}
break;
}
}
Init. your onClick inside onCreate():
taskname = (EditText) view.findViewById(R.id.taskname);
taskdetail = (EditText) view.findViewById(R.id.taskdetail);
taskdate = (EditText) view.findViewById(R.id.taskdate);
taskadd = (Button) view.findViewById(R.id.taskaddtask);
taskadd.setOnClickListener(getActivity); //<----here
Use properly onClick, don't init. the view twice:
public void onClick(View view) {
if(view == taskadd) {
fromDatePickerDialog.show(); //use this properly
addtask=taskname.getText().toString();
adddetail=taskdetail.getText().toString();
adddate= taskdate.getText().toString();
InsertData();
Notification();
}
}
Also to get the context of fragment. Remove getContext() from Notification:
Remove this:
getContext();
With this:
getActivity();

how to make same instance as new instance to top of the stack when same instance is running in android

Here the group chat activity is running currently. Group chat activity means chat window. in that chat window i retrieved the message from sqlite and showed by list view adpater. Here i am doing group chat for one event when new message is arrived for other event the notification issued. When i click the notification my group chat activity is not executed again even if i passed the intent from other class or activity.
This is my groupchatActivity code

You need to do couple of things to achieve the result.
Set launch mode of groupchatactivity to SingleTask
Override onNewIntent() method in groupchatactivity
Call setIntent(intent) for new received intent in onNewIntent()
Reflect as appropriate on above answer.

Alarm Manager Does Not Execute Repeatedly

I'm working on a group project for a class I'm taking and we cannot seem to figure out why our Alarm Manager does not fire intents repeatedly. We've picked through the source code from top to bottom and cannot seem to isolate the source of this issue.
Can anyone recommend a fix? (or perhaps a starting point?)
// Start service using AlarmManager
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 10);
Intent intent = new Intent(Rules.this, LMW.class);
PendingIntent pintent = PendingIntent.getService(Rules.this, 0, intent,
0);
AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
7 * 1000, pintent);
// Start 2nd service using AlarmManager
Intent intent2 = new Intent(Rules.this, KillTimer.class);
PendingIntent pintent2 = PendingIntent.getActivity(Rules.this, 0, intent2,
0);
AlarmManager alarm2 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
120 * 1000, pintent2); // here

http://android-er.blogspot.in/2010/10/schedule-repeating-alarm.html
I have had a similar problem and perhaps it applies to you (hard to tell since the code you supplied is pretty hard to navigate).
My issue was that applying multiple intents to the manager that evaluated as equal overrode the previous applications of that intent. See http://developer.android.com/reference/android/content/Intent.html#filterEquals(android.content.Intent) for what I mean by equivalence.
As an example, I had a schedule that used the URI domy://thing, with extras that varied over each intent (I need to fire the same action with different arguments each time). Extras don't count in equivalence, so my alarms were getting overwritten by each other.
To get around this, I stored a queue of my alarms in a separate file and when one fired, popped the next off the top and put that in the manager. Maybe that'll help you.
UPDATE:
No examples publicly visible, but try this (Trigger is a simple object containing a URI and a time it needs to be fired, scheduleDb is a class that extends SQLiteOpenHelper):
/**
* Pops the next trigger off the queue, adds it to the alarm manager, and
* stores it in the DB in case we need to cancel it later.
*/
private void scheduleNextTrigger() {
Log.d(TAG, "Popping next trigger off queue");
Optional<Trigger> nextTrigger = scheduleDb.getNextTrigger();
if (!nextTrigger.isPresent()) {
Log.d(TAG, "Trigger queue is empty");
return;
}
Trigger trigger = nextTrigger.get();
Log.d(TAG, "Scheduling new trigger " + trigger);
PendingIntent operation = createPendingIntent(trigger);
long timestamp = trigger.getTimestamp();
// Ensure the next item is in the future
if (timestamp > clock.currentTimeMillis()) {
Log.v(TAG, "Found valid trigger: " + trigger);
alarmManager.set(AlarmManager.RTC_WAKEUP, timestamp, operation);
}
scheduleDb.setScheduledTrigger(trigger);
}
private PendingIntent createPendingIntent(Trigger trigger) {
// AlarmManager allows only one instance of each URI, and seems to randomly
// delete bundled URI extras, so we'll encode the triggered URI and place it
// on a constant stem
Uri triggerUri = Uri.parse(TRIGGER_URI + "?" + Uri.encode(trigger.getUri()));
Intent triggerIntent = new Intent(Intent.ACTION_VIEW, triggerUri);
triggerIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Log.d(TAG, "Created trigger intent " + triggerIntent);
PendingIntent operation = PendingIntent.getService(this, 0, triggerIntent, 0);
return operation;
}
Hope that helps
