It works fine for like 10 secs it loops for 10 times but after that it stops for like 30 secs and shows this error:
LOG_CAT:
190-318/system_process E/ThrottleService﹕ problem during onPollAlarm: java.lang.IllegalStateException: problem parsing stats: java.io.FileNotFoundException: /proc/net/xt_qtaguid/iface_stat_all: open failed: ENOENT (No such file or directory)
03
Then the same thing happen loops for 10 secs then stops for 30 more

Yes Service can read SharedPreference and can make notification.
If I understood correctly, you need to create the notification in the onPostExecute function of your MyAsynk class.
So you may try adding an public attribute in your AsyncTask like this.
class MyAsynk extends AsyncTask<Void,Void,StringBuilder> {
public boolean showNotification;
// .. Other functions
}
Now in your UpdateTimerTask
if(datanews != checker){
asynk = new MyAsynk();
asynk.showNotification = true;
asynk.execute();
} else {
asynk = new MyAsynk();
asynk.showNotification = false;
asynk.execute();
}
Now in the onPostExecute of your MyAsynk class, you need to check the boolean and create the notification accordingly.
#Override
protected void onPostExecute(StringBuilder stringBuilder) {
try {
JSONObject jsonObject = new JSONObject(stringBuilder.toString());
JSONArray array = jsonObject.getJSONArray("articles");
for (int i = 0; i < array.length(); i++) {
JSONObject object = array.getJSONObject(i);
String title = object.getString("title");
String desc = object.getString("description");
String newsdata = object.getString("publishedAt");
datanews = newsdata;
titlenotif = title;
destnotif = desc;
}
// Create notification here on demand
if(showNotification) createNotification(getApplicationContext);
}
catch (Exception e){e.printStackTrace();}
}
Update
From comment
Maybe somehow it is necessary to check the date of the publication of
news, verify it with the current date and display a notice .. So you
need to show the notice only when there is news
If you're planning to track the new news from client side only, you might have to do a lot of coding including keeping a local storage and checking each time if a new news arrived or not. You need to have a server-side implementation here I guess. Which will send you a push notification when a new news is received. The server should handle the syncing and other mechanisms.

The error that you have mentioned says you have error on following line.
projectName = respObject.getString("projectName");
"responseObject" is null, hence you are getting NullPointerException.

Can someone help my with that? Thanks! :)
Change on doInBackGround return null to:
try {
return new JSONObject(reusults);
} catch (Throwable t) {
return null;
}
Change you broadcast receiver call in your doInBackground().. as
runOnUiThread(new Runnable() {
#Override
public void run() {
broadcastIntent = new Intent();
broadcastIntent.putExtra("correcto", results);
broadcastIntent.setAction(ACTION_REQUEST_ROCODROMO);
broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
_ctx.sendBroadcast(broadcastIntent);
}
});
and check null result in onPostExecute as..
if(null!=jsonResponse) // avoids null pointer;
Hello below is a method where fileUpload method is called and after uploading files i want to delete the synchronized object and i did so. and now i have to reload the page by calling fillRecipients() method, what is does is it lists all the information from the database and shows in the listView.

if (image != null) {
imagesArray.add(image);
}
}
try {
serverResponseCode = uploadFile(imagesArray, info, latitude, longitude, id);
if (serverResponseCode==200){
mDbHelper.deleteRecipientRecId(id);
//Line NO 230 here i want to add fillRecipients() method
}
dialog.dismiss();
} catch (IOException e) {
e.printStackTrace();
dialog.dismiss();
}
}
cData.close();

}
This is my fillRecipeints() method:
private void fillRecipients(){
mCursor = mDbHelper.fetchAllRecipientsInfo();
if (mCursor==null){
System.out.println("empty cursor");
}
else{

Im currently developing a Music Player and due to the fact that each time the orientation changes on the Phone and the Activity is re-created, I wanted the music to be played by a service. This way, the user is able to leave the activity without the music stopping..
Now.. I have this weird issue I been unable to solve... Each time I created the Activity and Inflate the GUI, the service is started. But the Service always gets Bounded after the Activity has send the data... So the music never starts... I know this happens because if I add a Button to resend the data, the Music starts playing...

I hope someone can help, im getting very frustrated with this! Also, Im pretty sure there is no problem with the media player, I tested it before without the service... the cursors also work properly... Thing is... Do I need to necessarily call the service from the GUI for it to play the music?? What am I doing wrong?
EDIT: The website wont allow me to answer my own question so I post the solution here:
Ok, finally found a solution!
I read that the interaction with the service is only available once the onCreate method has finished... So, I added a Timer and filled it with the methods I needed to run:
new Timer().schedule(new TimerTask(){
public void run(){
sendBoolToService(playerActive, "playerActive");
sendIntToService(position);
sendStringToService(action);
}
}, 1000);
AND VOILA! It works! :D Hope its useful to someone!
What you need to do is to move the code in onCreate() which is dependent on the service being available to your onServiceConnected() method in your ServiceConnection implementation:
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder service) {
mService = new Messenger(service);
Toast.makeText(getApplicationContext(), "ATTACHED!", Toast.LENGTH_LONG).show();
try {
Message msg = Message.obtain(null, Background.MSG_REGISTER_CLIENT);
msg.replyTo = mMessenger;
mService.send(msg);
sendBoolToService(playerActive, "playerActive");
sendIntToService(position);
sendStringToService(action);
} catch (RemoteException e) {
Toast.makeText(getApplicationContext(), "Connection failed!", Toast.LENGTH_LONG).show();
}
}
public void onServiceDisconnected(ComponentName className) {
mService = null;
Toast.makeText(getApplicationContext(), "UNATTACHED!", Toast.LENGTH_LONG).show();
}
};
I would also look at your service implementation as I cannot understand why you are calling mService = new Messenger(service). Your IBinder instance should provide you with a mechanism for obtaining a reference to your service instance.
In my case, my issue was using android:process attribute for <service> element within Android Manifest, which is supposed to improve performance, but in reallity, maybe it does once the service is running, but it takes a very long while to reach onCreate() (and so also to reach onBind()). For me it was taking minutes. Now Apps and services run smooth and as expected.
I now this a very old question, but showing your Manifest file here makes sense.
