HTC EVO 4G :: Check Apps For Data Polling
Sep 15, 2010
I went into Weather Bug (free version) to check the weather and accidentally hit the menu button. Decide to check preferences for the heck of it and I see "Enable Updates' set to yes and Update Interval set to every 1 hour. What?? I know it's probably not a huge drain - but I had no idea that it was checking on a regular basis (and why I don't know). So please check your apps to make sure they are not updating data auotmatically! After that I went into every app I had to make sure I was either signed out or or set updates to manual.

I working on the app where I get the data from the server using rest call and add it to the view. I get all the initial data correctly. I use AsyncTask for doing it. Now I want to periodically (say 2 mins) fetch the new data from the server and add it to view.Periodically fetching data (polling) from the server in Android.

I have google voice. And the quality is excellent but im on a non data plan so I can't check it out in 3g. I live in a t-mobile edge zone so I want to know about the voice quality & reliability cause I'm planning on getting a nexus with a t-mobile data only plan. Will it be like a regular phone call or will I have poor quality?

I have successfully been getting GPS data through the registerLocationListener() and onLocationChanged() methods. The only problem with this is that the speed reading of my app freezes if there is no more GPS data (e.g. when I go indoors, enter a tunnel, etc). The behavior I want for my app is that the user is somehow notified that the speed reading is probably not accurate due to a lack of fresh data (set speed to zero, blink the speed reading, etc). How can I do that? I though of checking periodically whether the GPS unit was detecting any satellites, but I'm not sure how to force periodic checks.

I'm using a PreferenceActivity with a PreferenceScreen defined in a xml file. i want to make sure that the data set on a preference editor are valid (integer , integer in a range....)
So , i want to be able to intercept a click on a button of the EditTextPreference , check the validity of the data and if the data is incorect , display a message to the user and come back on the EditTextPreference.
What would be the best way to achieve that?

I'm doing Major Project on my final year and I'm very new to Android plus I;m not good at codings. I need help with my login page. I've created something like a database connection java file which is this:
CODE:......................
I've already created a database for users using SQLite. The database name is Users and the table is called User. The records inside the table are Username, Password, LastName, FirstName. I've inserted one user's info into the database. The problem is I do not know whether my UserDB.java is correct.
And I've also created login.java. Hardcoded Login page:
CODE:........
So I want to know how I should apply the database connection on the login.java. Should I insert database connection something like db.Open();? I studied ASP.Net a few months back and I kind of forget most of what I've learnt.
So how should I open the database connection on login.java and how to check with database whether the user enters the right username and password?
Just incase you need my xml, here's the code:
CODE:......
I need to learn how to do it so that I can apply for other pages for example Register.java page.

So it looks like mobile phones these days are capable of providing gps data ;) I'm building a django app with a mobile edition that I want to be location aware. My question is, how does one access GPS data? Is there a standard, or do you have to custom code for android/iphone/other. Ideally, I'd imagine it being provided in the HTTP request in the same way you get information such as the IP Address and User Agent.

I intend to develop an app on android that can help people selecting the best pizza/ice cream/hot dog in a certain town based on their ratings through a poll. Now what resources do I need to achieve the desired solution? Do I need a web service or website/device connectivity for the desired poll? I would like to start off with a simple application that just shows polls or ratings for a certain item.

This morning I power cycled my Eris for for first time in a week or so. After that, the notificaton area said I have four updates waiting.I think I selected the "My Tracks" app for update, but when I did, it told me to make sure I had at least 40% battery charge, the phone would be unusable during the update, etc., and it proceeded to install the OTA update to build 1.17.605.1.That's fine, but now the phone doesn't show any apps with available updates.Will these apps automatically notify me again that updates are available? Do all apps routinely check?

Sometimes (it's not usual, but sometimes it happens) my phone (Nexus one, CM7) runs quite slowly, and not fluent at all, just because of an app that is eating all the memory / processor. If I kill that app, problem solved.
When this happened the first time, I went to the running services section in settings, and I checked that the services listed are not ALL the running processes, so even if I kill all the services there, there are still running apps. Then, I tried to install several app killers, just to check if they kill all the running apps, but not only they don't list all the running apps, but also when killing all, there are still apps that keep running (like some games), and the only way I found to find them is checking one by one in the apps list, if they are running or not.
Is there any app to check at once ALL the running apps? I have looked for it, but all I have found are apps to do exercise ("running apps", D'oh!), and stuff like that?

I am required to work on an application which is be deployed on devices running Android 1.5. The application is supposed to maintain a connection with a server and regularly poll it for new data. The server will notify the client of new data following which the client will connect to the server and download the data.I know that ideally a push based approach will be more conducive here given that we are to run this on a mobile platform. Also, from Android2.2 there is going to be support for C2DM(Cloud to Cloud device Messaging) but as already mentioned this application is for devices running Android1.5.Implementation: I was thinking of using AlarmManager which would Broadcast Intents periodically(poll interval), The Broadcast receiver will then try to connect to the remote server and make data changed check. If the server has an update, the thread will connect to the remote server and download the data from the server.
Problem and Issues: 1. Is this the right way to approach the problem? 2. Is AlarmManager reliable? Would it remember Alarms after a device boot? (I think it does) 3. How do I ensure that battery usage is kept at minimum.(I have heard something about using "keep-alive" to sustain the session for longer time..what is this legend?) 4. What are other things that I need to consider? I am sure I must be missing lots of things here.

Is it possible to do polling in Android? For example, I want my application to monitor a directory continuously. If there is for example a new folder created in that directory I want to log it down. Is it possible to acheive this by polling? Or is there any other way to do this?

I have a Service that uses the LocationListener, and it will be running from boot, indefinitely. My question is, how often is too often to listen for location updates? Is 5 minutes a battery killer? What about 1?

I'm trying to pulse my bluetooth dongle, to see if it is range. Every second my Android sends a char to the dongle, which then responds with a char. If there is no response, or the char is wrong, then it should conclude that there is no connection. I'm able to send from Android to dongle (attached to MCU), and the dongle is able to respond. All I need is a simple way to read each char (when received) to compare it. I'm trying to do it in a seperate thread to make it run in its own loop.
Here is my code so far, but I think I might be off, so if you could give me a pointer!
void readFromInputStream()
{
Thread readFromInputStream = new Thread()
{
public void run()...............................

what I need to do is auto-register device if not already done and then start polling messages with the credentials I received through this registration. Now, after I read quite a bit about services, threads, asynctasks and the AlarmManager I'm totally confused about how to handle this. :-s So, there are my two main tasks. What would you recommend as a not-too-silly approach
1.) Registration
I'm currently spawning a service from my UI thread if there are no credentials saved in the DB. Inside this service I start an asynctask that POSTs my request to the server and receives the credentials for the new device. stopSelf ends the service.....................

I went into the notification bar to see I had two updates for apps that I have. However only a second or two after the notification window was up it suddenly disappeared and kicked me back to my home screen. When I returned to the notification window the app update notifications were no longer there. Is there a way that I can make my Droid go check for updates again?

I've noticed this before but haven't given it much thought, but I've noticed that it seems that certain apps are running in the background for no reason. I usually notice this by checking task killer. However, just now while using another app, I got a force-close error for ShopSavvy, which hasn't been used in several days.
Why would something like this run randomly in the background? Is it part of an update check? Any ideas?

Ever since I upgraded to 2.1 my email accounts have not been polling like they are set to. In some cases, it won't poll until I manually check it. I've tried 2 factory resets, but no luck. They are set to 5 min.

- Does the standard Gmail application that comes with the phone (not the email app) utilize polling on a set schedule, or is it set to automatically push messages to the phone as soon as they hit the Gmail server? I have noticed that what it does seems to correspond to my Google Account Settings (and what I have checked). Specifically, when I check off the "Sync Gmail" feature, I seem to get my Gmail emails on my phone in real time. Does this mean that checking this option allows Gmail to "push" emails to my phone, or is it simply polling at very frequent intervals?
- Which, in your experience, uses less battery: setting the phone to poll for e-mails every 30-60 minutes, or simply having the server "push" the e-mails straight to the phone? Also, does "pushing" e-mails work when Syncing is turned off (via the Power Control widget)
