Android :: Looking For Definitive Location Finding Logic

Mar 31, 2010

I am looking for a tutorial that explains the logic for fast, robust location finding.Basically I am sick of Google Maps finding my location so incredibly fast and accurately while my own application struggles to get a location.I would be fine with pseudo code responses and I will explain what I am doing so maybe I can be shown what I am doing wrong.

1. Get the locationManager object.

2. Do a 'get best provider' call.

3. Get a list of all available providers.

4. lm.requestLocationUpdates(bestProvider, 0, 0, this); hit the location provider as much as I can to get my first signal

5. Send a delayed message.If a location cannot be found in 10 seconds, switch to a different provider and try again with lm.requestLocationUpdates(nextProvider, 0, 0, this);

6. Repeat step 5 until I have a location.

7. Once a location is found determine if it is the most accurate provider.If it is not try again with the most accurate provider on an 8 second delay.If it is the most accurate provider then set lm.requestLocationUpdates(currentProvider, 30000, 0, this); to conserve battery

8. Make sure to lm.removeUpdates(this); before changing the requestLocationUpdates

Now it occurs to me that it may be possible to iterate through my list of providers and do requestLocationUpdates for all providers at once.Is this a viable option or can you only listen to one provider at a time?I have seen that location from onLocationChanged has getProvider()to let you know who provided the location information so that I can know which provider is actually finding a signal and turn off the others.

Android :: Google Latitude Finding Wrong Location

Mar 6, 2009

Ever since the RC33 update where the new Maps version came out with Latitude included....my Latitude acct has been...well...off.

I'm running my GPS when Maps is used...rather than a triangulation method w/ the towers. However...there have been QUITE a few occurances where Latitude shows me in a totally different STATE. I live in metro Atlanta, but apparently, I spend a lot of time at a country club near DFW in Texas. Once, I was going down the road...started up Maps, and it was tracing me going up an interstate in a city 120 miles away from me. At the time, I was no where NEAR an interstate...but Maps was showing my movement second by second.

This is rather irritating. Google developed the O/S, they developed Latitude...yet Latitude seems to work fine on other phones OTHER than the G1. Upon reading up on Google's Help Forums...I'm not the only one with problems when it comes to Latitude and Android.

Android :: Definitive Ad Mob

Nov 16, 2009

After searching their website, all of the message boards and googling it to death - I have formed only somewhat of an answer to the following...

1. How much does Ad Mob pull if a user simply loads your app

2. How much does it pay if they click an ad

3. What is an average Ad Mob income in a given month (for a single app)

4. Preferred method : (a) Ad Mob (b) Make it a paid app

Fully aware that Android apps aren't exactly cash-cows, but a little extra income never hurt anyone, trying to figure out a planned implementation to acquire such.

HTC EVO 4G :: Is There A Definitive Way To Prevent OTA Updates?

Nov 17, 2010

This is my first post on this board and I wanted to express a great deal of thanks to everyone for the wealth of information avaiable.I recently rooted my EVO and installed Myn's 2.2 ROM which I am extremely happy with.There is NO CHANCE I would have done this without all the great info here.I have looked for this information and am a bit overwhelmed - this is the first phone I've rooted, so I am proceeding extremely carefully with all the things I do with it.I can't seem to find a definitive answer how to prevent OTA updates entirely.I'm not even sure I have to worry about it since I have a new ROM installed.The last thing I want to have happen is to wake up some morning and suddenly my phone is unrooted with a new version of Sprint's ROM. I am perfectly happy waiting for custom ROMs to come out with feature changes (for example, Gingerbread). If I never see an OTA update prompt again, and I can be sure it won't apply itself without my intervention, I'll be happy as a clam.

Android :: Logic Different Between Using Keypad - With Finger Tapping?

Jun 19, 2009

I have a ListView. When I click a row Item (which are just TextView instances) I want them to remain hilighted (default orange color). The default behavior is that they flash orange.

Strangely, if I use the key pad (arrow up/down) to move between items, it has the exact behavior I want. Why is the logic different between using the keypad or with finger tapping?

Games :: 1 Minute (Logic) Game For Android Market

Mar 7, 2010

I'd like to announce the release on the Android Market of our last creation: 1 Minute Game. The main concept is very simple. The computer shows puzzles based on numbers, shapes and colours: the player must solve them and touch the correct answer to go to the next round, trying to be as fast as possible. We implemented 3 different modes that must be unlocked by playing more and more. You can play games under the "Training" areas so to train yourself and challenge your friends locally (there are 6 slots to store the profiles of the players).

Online Challenge
But the core of 1 Minute Game is the online challenge, which allows the players (once per day) to play a special match and to send the result to an online leader board. Each score shows also the nationality selected by each player try to get your country at top of the ranking. The ranking is visible both through the application and visiting the web site of the game.

Free DLC
In order to make the game more appealing and let you enjoy it for more time, we are developing new games to be released for free in the next versions of the application. For example, this morning (it's a matter of minutes) we will release the version 1.1 which contains a brand new game in the training section: The intruder. In each round, all of the objects shown on the screen share the same characteristic (same shape, colour, number or animation) except for one: that's the Intruder!

New games of logic will be released once they are completed and fully tested through future news.

LITE version
There is also a LITE version in the Market: 1 Minute Game LITE (limited number of levels, no online challenge and 2 slots to store the users' profiles), so you can try it and see if it is worth to buy the Full one. This LITE version includes the additional training "The Intruder" as well.

DOWNLOAD
the game can be downloaded from the Android Market. Just search for its name or click on these links with the browser of your Android smartphone:
FULL version - market://search?q=pname:com.wepromite.oneminutegame
LITE version - market://search?q=pname:com.wepromite.oneminutegamelite

Android :: Responding To Preference State Updates Logic

May 1, 2010

I am calling a PreferenceActivity from another activity and then updating the application state (ie: changing the font size) on onActivityResult, based on the preference changes. I was thinking it would be better to put the state update logic in the PreferenceActivity. That way I don't have the duplicate the logic in each activity that calls the PreferenceActivity. What's the best or correct way to do this?

Android : Game Math / Logic Calulating Movement?

Aug 26, 2010

I know this is more of a general programming question, but my Android friends here have always been helpful. I am trying to make an image move from one part of the screen to a position the user touches, as a constant speed. I don't know the best way to go about doing this and the way I have been trying to get to work is taxing my brain too much.

I have been using geometry to calculate slope, then using Sin * movement speed to calculate the difference in X,Y coordinates.

This is the codecode...

The problem that I'm having is the image is veering way of course when traveling in Y heavy paths. When traveling horizontally it works almost perfect.

I know there is probably an easier way though I don't know how to use a lot of things (like OpenGLES) so if your advice is to use a different method please link a tutorial for that method if you know of one.

Android :: Making Game's Logic Supporting Multiple Screens

Jul 25, 2010

I've read the article "Supporting Multiple Screen" on Android developers site. But that doesn't apply to game logic.Let me get straight to the point. My situation is as follows:

- I'm creating a game using LunarLander code as a base.

- In my game, there'll be an object flying up from the bottom of the screen. The object will fly in projectile motion.

- I set the starting velocity, gravity and angle so that the highest point(of projectile motion) is almost at the top of the screen.

- The screen tested is Motorola Milestone. (480x854 resolution) Meaning the object travels around 854 pixels vertically.

I'm thinking of adjusting starting velocity based on screensizes. But that sounds unreliable when we've so many devices/resolutions out there. How do you combat these kind of problem when making games?

General :: LG L35g Optimus Logic Pause In ClockWorkMod Boot Loop

Jan 25, 2013

My stats:

LG L35g Optimus Logic from Net10
Running Android 2.3.6
It is rooted.
Clockworkmod 5.8.4.5

Okay, first off this is totally my fault that this phone is stuck.

I was inside the About menu of android and saw there was an update for 2.3.6

So, stupidly, I decided to select it. It downloaded the update, rebooted, and then wound up at the clockworkmod recovery screen.

I tried the "reboot system now" option, but it just reboots back to the recovery screen.

I have used the "wiped data/factory reset" option. I've wiped the cache partition and Dalvik cache.

I didn't backup the stock rom, so I found these two roms for the l35g from here:

AA51

Stock (user modded version)

I used the restore option in recovery mode, but the "Stock" rom above didn't take. The AA51 rom did install fully and told me to reboot. I did, but it still went right back into the boot-loop!

I think the solution to this is to fix the boot-loop issue. Would Zengarden or Xionia work? Then, if so, I need a version of it to work with the l35g.

Android :: Android OpenGL Game - App Architecture / Threading Logic

Apr 8, 2010

Surprisingly, I don't seem to have issues with the OpenGL side of things (which is very unusual), but my problems stem from getting a clear idea for app architecture and a few other problems. Right now, most tutorials on the net just describe the render portion. I know that when I create a GLSurfaceView and hook a Renderer into it, it uses it's own thread for rendering.

I want to do logic operations and other gameplay stuff (like moving characters and whatnot) in it's own thread as well. Can anyone explain a good approach to this? I'm guessing the two threads will have to be synchronized (do logic, render, repeat), and limited based on time so that it performs smoothly across different devices.

Android :: What Logic Does Contacts Api Use To Aggregate - Overlapping Fields From Multiple Raw Contacts

Nov 2, 2010

when a "contact detail" screen is presented in the contacts application, how is each field aggregated from its underlying raw contacts

case 1: Overlapping fields

when the same field exists in two or more contacts. Say they have two different last names or emails in different accounts. Does the contacts app show both fields with an account indicator?

case 2: Non overlapping fileds

one rawcontact has email while the other one has phone number

Short of scouring the source code, I have exhausted searching everywhere else.

Samsung Galaxy S :: Definitive Guide To Save An "image" Of Phone?

Oct 6, 2010

I have had my Samsung Galaxy S for about a month now, and have just recently took the plunge and rooted it. I am now seeking a means of backing up my entire phone using a method that will essentially "freeze" my phone's current state, allowing me to restore to this exact state in the future, like an image of my phone. I want all apps, SMS messages, contacts, all settings, everything to be frozen in time as a backup.

I have searched these forums and through Google search results extensively and found a lot of information, most of it regarding Nandroid, Titanium Backup, SPRecovery, ClockworkMod Recovery etc. My understanding is this:

Titanium backup is more of a soft backup, it backs up your apps and settings and allows them to be reapplied.

Nandroid requires the recovery mode to be flashed using ClockworkMod Recovery

SPRecovery can be used instead of ClockworkMod Recovery, but they both have their own pros/cons.

Is there a definitive guide to achieve what I want?

Most of the guides I have read have been tailored to other devices such as the G1, HTC Hero, Droid etc.

TL;DR: I want to make a complete backup of everything on my phone, save it as an image, and be able to restore it later.

Android :: Location Manager Minimum Update Time Overridden / When Location Changes?

Oct 26, 2010

I'm developing a mapping app using Eclipse 3.5.I'm setting the minimum update period with the LocationManager's requestLocationUpdates method, via a configuration activity. When I set the property I see in Logcat that the system process sets the value OK.When I actually send a new location from the DDMS emulator control and the location changes on the map view, I see that the system process then sets the minimum time to zero.Below is a capture of the system's log messages. You can see that I'm setting the period to 32 seconds, then 16, then, after I've sent a simulated location change the system sets it to zero.The map responds to location changes to location changes instantly even if they are sent only a couple of seconds apart.

In my application I have to fetch the current location. First it correctly fetches the location. But we are moving from the current location to some other location. It shows the previous address. It is not updating the location. My code is: locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); locListener = new MyLocationListener();locManager.requestLocationUpdates(LocationManager .GPS_PROVIDER ,0,0,locListener); location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location != null){latitude = location.getLatitude();longitude = location.getLongitude();} Please find the mistake and when i launch first time it is not working on second time itself it is working so check this thing also.

Android :: Location Provider / Coarse Location

Jun 25, 2009

The way we are retrieving locations from our Android phones is to 1st get a Coarse Location followed by a Fine Location. This is for the case where the user may be inside a building initially and unable to track satellites. After we get our coarse location we transition to a fine location to track satellites. This method has been working fine for several months. We recently upgraded to 1.5 and our mapping application, to my recollection continued to work.For the past couple of days we have not been able to get a coarse location and we are receiving a status message in the onStatusChange callback of.We have re- installed previous versions our code that used 1.1 and we are receiving the same status message of .TEMPORARILY_UNAVAILABLE. Other than the obvious description of the constant, we can find no meaningful information.

General :: Devices Reporting Wrong Location After Location Spoofing

Mar 15, 2013

Recently all my android devices think they are in Spain when I am at home in Toronto.

I think this was caused when I ran a location spoofing program on only one of my devices, one of the locations I set it to was Spain (among others).

I've tried clearing the data for the Network Location apps, changing the SSID on my router with no luck.

The only way it shows the correct location is when I go outside and run Google maps long enough to get a GPS fix. But when I go back inside I am back in Spain!

The devices this is affectingGalaxy Nexus with my google account

Nexus 7 with my google account

HTC Desire :: Home Location Fixed Instead Of Current Location

Nov 14, 2010

How could I fix the location which appears on the clock on the home screen and serves as weather forecast location? I am not living near a big city listed on the weather location list and when at home, the current location usually is indicated some dozen miles away from my home. This could be a cosmetic problem, but in the Alps (where I am living) weather a short distance away can be quite different from where you are.
Besides that, it would be nice to know the weather at home while beeing abroad.
