Android :: Need Display Metrix Xdpi / Ydpi Accurate?
Apr 15, 2010
Can the xdpi and ydpi settings be relied upon to accurately represent the physical pixels in once inch of screen space? I need this to be accurate for some display code I'm writing. I realize the documentation says that this is the case, but I need to know if individual handsets get this right MOST OF THE TIME. I know I can alternately use "density" which will give me 120, 160, 240 steps of DPI, but an exact dpi would be much better.

I'm totally new to the G1, coming from an iphone, but my gps when on (and can actually get a signal lock), seems to always have me on the grass or in the water if driving my any. Its rarely ever where I am. and im in a major city. Perhaps that could be why, but i always have clear view to the sky.

I've been looking for a battery widget to tell me my remaining charge state as a percentage, but so far all of them go in increments of 10% (i.e. 90% left, to 80%, to 70%, etc). Does anyone know of one that breaks it down a little more finely?

I need a recommendation from someone for the most accurate way of timing SoundPool sounds. I can't loop them because what's desired is not a loop but very accurate (to the ear at least) timing.

I'm trying to get my current location and show it on a map. Class com.google.android.maps.MyLocationOverlay.MyLocationOverlay does most of the work for you. But it's coming back with a very coarse result that's off by a couple of clicks. I'm listening for onAccuracyChanged() but that never gets called.
How can I get a more accurate location, when using MyLocationOverlay ?
PS. manifest has
<application android:icon="@drawable/icon" android:label="@string/app_name"
android:debuggable="true">
<uses-library android:name="com.google.android.maps" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

I'm writing my first location based android app, but got confused about some of the GPS service api. Here are some questions I have:
1) To get my current location, I called requestLocationUpdates() with a listener in the onCreate() method of one activity. But what happens when another activity starts and the current activity goes invisible? Is the GPS location update going to stop? If so, how do I keep it on after the activity is switched?
2) how accurate is the Location.getSpeed()? How is it computed? Can it tell the difference between on bicycle and on foot?
3) not really a question about android. How to calculate the coordinates of a location, say, 100m away from my current location?
4) To stop the GPS, I only need to remove all the listeners that have been registered to locationmanager?

I recently posted this question on stackoverflow (http://tinyurl.com/ yzrofne), but maybe someone here can help me. I am using the location manager's requestLocationUpdates() method to receive an intent to my broadcast receiver periodically. The system is correctly firing the intent to my broadcast receiver, and I have been able to use it correctly. The only problem is that the GPS location provider only stays active for a few seconds after the initial location acquisition, and I need it to stay on a little longer so that the location estimates are more accurate. For example, if I tell the location manager that I want an update every 5 minutes, it correctly fires the intent with location information from the GPS. However, the GPS only stays active for about 5 seconds, so it doesn't give much time for the location to reach a high accuracy (say, less than 10-20 meters). My question is how to make the GPS location provider stay active for each periodic request that comes from the LocationManager requestLocationUpdates. Does anyone know how to do this?

I hope this is the right section to post this, I have an HTC / G2 on a T-Mobile UK contract. I'm after a good weather forecast app that works well for the UK and Europe. I also use WeatherPro on my iPOD Touch (when I can link up to my home WiFi) and it is great - it picks up small towns, gives 5 day forecasts, 24 hour forecasts broken down into 3 hour time slots, shows satellite and radar, temperatures in 'F and 'C, windspeed and direction. It is very accurate too! I can't find it on the Android Market though.

I need to build compass for my application.
From reading the documentation it seems there are two reasonable ways of doing this:
Sensor.TYPE_ORIENTATION method: This is the easy way of doing it. The problem with this is it is not accurate. When I compare my reading with Snaptic Compass it is about 10-15 degress off which for my purposes is unacceptable.
Sensor.TYPE_ACCELEROMETER, Sensor.TYPE_MAGNETIC_FIELD and getRotationMatrix() in conjunction with remapCoordinateSystem() and getOrientation() method: The documentation says this "is usually more accurate". The problem is regardless of the delay I register with listener the compass goes crazy even when the device is stationary on flat surface.

Is anyone who is using 3G Watchdog or NetCounter actually receiving accurate stats compared to what Orange are showing on their OrangeWorld "Your Account" section?
I have been using my new HTC Hero for just over 2 weeks now and Orange are saying that I have used 422MB of data. This seems ridiculous to me as I only automatically check email once per hour, surf to the extent of anyone with such a new gadget, and spend every evening at home connected to WiFi from about 6pm onwards.
I phoned Orange one day last week and they advised that I had used 310MB up to that point, so I immediately downloaded 3G Watchdog and started it running. Since then, it says that I have used 36MB in the same period that Orange say I have used 112MB.
I also use NetCounter, but as I didn't reset it last week, I can't make any specific comparisons. However, on a daily basis it always agrees with 3G Watchdog to within a few KB.
I know I will need to phone Orange to sort this out, and I am certain that they will tell me that downloaded data counter apps cannot be trusted. I'm not sure how I can prove to them that their data readings for me are wrong.

Many times when I look at different weather apps, the current temp is always either the low or the high. Never seen this on a news or weather channel.

New Incredible user just looking for some feedback, my battery stats are the following:

Battery use:
-Android system: 34%
-Cell standby 29%

Even having this thing sync regularly its not accurate. Where is this weather coming from? I changed to weather bug and weather channel, both free apps are way better accuracy wise.

My girlfriend recently bought the Incredible.She says the voice dialer app isn't very accurate, is there a way to train it? I had her go into the voice recognizer settings but the option to train it is not there as it was on the D2.She also says it doesn't prompt her for confirmation and she can't find the setting to have it confirm before dialing. Is there an option she's missing?

I just got the update for GPS fix not to long ago, so I decided to test out the new Swype mic and here is what I found wrong with it. The Swype is by far less accurate then the Android keyboard mic. Even if you have cuss words programed into your Swype; when you say cuss words it will show as #### if even at all. All in all I suppose 2 might not be the biggest deal in the world, but 1 is a huge deal.

I have tried 2 GPS trackers and both were not accurate for measuring distance. I used My Tracks and Cardio Trainer. I really like Cardio Trainer but it adds 3 tenths of a mile for every mile. My Tracks was off as well. Anyway just wondering if anyone has had good luck with another application?

Anyone having problems with accurate temps shown on the home screen. Mine were right on but today they are off 4-5 degrees if I use Accuweather or switch to Google Weather. Have refreshed and rebooted to no avail.

Are battery apps accurate because I get diff readings from the phone then the app. Also does the battery app waste battery life when checking it frequently.

This is my 3rd HTC but first Android (Had a Blackberry Curve too). Like Hero a lot but the onscreen keyboard is driving me batty! First off, it doesn't work well if my fingers are cold. And second off, it does not seem to be accurate, especially on the far right hand side. Also, I swear my fingers are quite small and even if I press a letter smack dab in the middle, I get the letter above. And don't get me started on the backspace key.
I really really like my Hero. But I need a different onscreen keyboard. Can anybody make any suggestions? I can't do any programming, etc. so it will have to be a pretty much straight download.

With original ROM clock widget and weather widget i would always be told about the weather in specific area that i was in really accurately, but now, with custom ROM the 'current location' just shows the name of the country I live in! (Lithuania) I have to manually add my home town. I am lucky to live in capital city, so I add it, but if I go out elsewhere, the widgets become useless. any solutions?

I opened google maps and my location is not accurate at all. I understand that if I turn on gps options it becomes much more accurate, but it's a real battery eater. coming from a 2 year old samsung mysto on Helio network that ran google maps down to the meter for me (and only needed to be recharged every 4 days) it seems like this should work better.Am I missing something? That little mysto couldn't have been running active GPS pinging the whole time. What made it so much better at locating?

How do I transfer files to the phone, or more accurate where do I put them. On my PC I found the memory on galaxy, (O:) and then DCIM, but then what. Does it matter or can I make my own folder for example Sense ROMs, or music or whatever.

Has anyone else noticed how disgustingly accurate/sweet the Google Maps Traffic Layer is?I put it on my dash and when it's green, the highway is at least 50 mph +..I noticed that the second my gps triangle entered the orange/yellow, it slowed down to about 25 mph..Immediately after leaving the yellow, it went back up to 50+..Everyday before I leave work, with a swype and a click, I know whether or not I should be getting on the highway or not. Right now it's red - I'll be taking the lake home today.Holy crud muffin I love this thing.

Google maps shows my current position of several streets away. I know it says accurate to 400 meters so I'll live with it, but when it states my address as being a village several miles away it annoys the hell out of me, particularly as I live in a medium sized town.
