Android :: Web App GPS Polling

Jan 11, 2010

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.

Android :: Create Polling App?

Aug 4, 2010

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.

Android :: Best Approach To Implementing Polling

Jul 12, 2010

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.

Android :: External Bluetooth Polling

Nov 9, 2010

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()...............................

Android :: Registration And Polling Of Messages?

Aug 25, 2010

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.....................

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.

Motorola Droid X :: Push Email Better For Battery Or Polling?

Jul 27, 2010

- 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)

Samsung Moment :: Moxier Mail Polling Mode Not Updating Properly

Dec 19, 2009

for those of you running moxier mail on exchange with a polling mode, have you ever noticed it doesn't successfully always update? I am seeing that at times i will set it to a 1 hour polling mode for example but it won't bring down new emails. If i notice on the moxier settings page the last synch'd time is further back than the polling interval i'll hit 'synch now' and it ALWAYS brings down any new messages.

I contacted moxier and they seem to think its an issue with my server. I should also say my IT department doesn't support moxier/android explicitly but there is no reason it shouldn't work as designed they say. I have dug into the moxier logs and it seems that everytime i see a failure the following similar entries appear to be in the logs:.............

Android :: Android 1.6 - Android - View - WindowManager$BadTokenException - Unable To Add Window - Token Null Is Not For An Application

I'm trying to open a dialog window, but every time I try to open it it throws this exception:

CODE:.................

I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached it since it seems like I'm missing something:

Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.

Android :: Android WebView Not Loading A JavaScript File But Android Browser Loads It Fine

Jun 3, 2010

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebSettings;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class myKMB extends Activity {
I already have JavaScript on the web browser on, the problem is the web view is acting to different from the web browser.

Android :: Android - Add Menu Item To Android's Built-in Apps

Aug 17, 2009

I'd like to add a menu option to the Android camera app. Is this possible to do using the current SDK? I know I need to add an intent-filter tag in my activity. But I don't know what I should put in the mime type. I want to be able to process the live camera previews if the user selects the menu option. So what do I put into the type tag of the intent-filter? Also I suppose I won't be using ALTERNATIVE or SELECTED-ALTERNATIVE for the category as I want to deal with the whole intent?

Android :: Android IRC Office Hours - Android Bluetooth RSSI

Jan 27, 2010

I have a question about bluetooth RSSI functionality on the Android (either 2.0 or 2.1):

It's easy enough to get the RSSI value when a bluetooth connection is created, but how can you repeatedly get the RSSI value of a connection that is already active? It's really important to be able to do this, because this lets you determine if bluetooth devices are close to each other or far away, but I can't find any appropriate function calls in the Android API.

Android :: Moto Android Stuck On Android Splash Screen

Feb 5, 2010

I am having a bit of a problem with my Android. So what happened was I downloaded "DroidRootPro" from the market. I rooted my phone with this, installed the 800MHZ ROM image, rebooted and the phone came up great. I was actually surprised on how fast it became. Once the phone came back up, I tried installing one of the custom themes that came with that app (I know I should have left it alone). The phone than rebooted and I was never able to bring it back up. It gets stuck in this endless loop where it tries to boot but doesn�t get past the "Droid" splash screen, it just keeps rebooting every time.

Things I have tried:

-Wipe data/factory reset (in recovery mode), no go.
-Wipe cach partition, no go
-Restore from a "nandroid" backup, no go. I tried pretty much every combination of restores and am unable to bring the phone up.

Is there anyway I can download the factory image that comes with the phone, put it on an SD card and restore to that? I have looked all over but cant find any information on this.

Android :: How To Reference R.java Of Other Apps In Android - Like Com.android.music

Sep 29, 2010

I am trying to develop an app to supplement the built-in music player. I've used git to download the com.android.music package and looked around at its code. I can launch the music player by copying some of its code and launching activities with intents.

Now what I need to do is get a handle to its current view. In the MusicUtils.java file, I see a line that says

View nowPlayingView = a.findViewById(R.id.nowplaying);

I'd like to do the same thing. Only I don't have access to the R.java file, so I can't write e.g. R.id.nowplaying. How do I do this? How do I reference the music players R.java? I do know the R.java stuff is declared public so that shouldn't be a problem. Right?

Is it even possible? I saw this related question and am now wondering: http://stackoverflow.com/questions/2437271/how-to-load-com-android-music-code-into-eclipse-and-compile

I'm working against the Android 2.2 SDK, but it'd be helpful to know if the answer is different for older versions such as 1.5.
