Android : Collect Sensor Data While The Display Is Turned Off?

Jun 7, 2010

I'm using Android 2.1 on a HTC Nexus One. I want to collect sensor data while the device is turned off.
By using android.app.Service this works well while the app is in the background but stops working when the display is turned off by the hardware button.

Is there a possibility to collect sensor data while the display is turned off?

Android :: Keyboards Which Collect Data

Jul 28, 2010

Is it safe to use 3rd party Keyboards, (such as Big Buttons etc)? I only ask as i installed a keyboard app, went to enable it but it came up with information saying it collects credit card data and password data.. Wasn't comfortable with this so cancelled enabling it and uninstalled.. I need a keyboard as the one on my phone is pretty good but a bit too small. Can anyone shed a little light on this and recommend me a Big keyboard for the Pulse mini

Android : "Collect Anonymous Data Usage" / Unable To Update

Jan 25, 2010

So, my music player app (Meridian) has decided to implement an update which "collect anonymous data usage" which doesn't sound cool to me. So, what if I just don't update? I assume the dev can't collect info from me if I don't update, correct? Will the version I'm using expire or something?

Android :: Bad Compass And Sensor Data

Jul 22, 2009

Am researching a problem with compass and sensor values returned by the phone. I found this thread: http://groups.google.com/group/android-developers/browse_thread/threa. Which seems related, but it's old so I'm starting a new one. I'm getting stuck values from both the compass and orientation sensors. It was fine yesterday, but today, I'm only getting values in a limited range (e.g. compass headings from 240 - 290), no matter how I orient the device. What's even more odd is that the radians returned from the call to Sensor Manager.get Orientation(), which returns radians, is giving consistently out of range values. Anyone see this same behavior, and if so, any fixes? Here's some sample sensor data. Format is heading, pitch, roll. The first set contains raw values, the second set contains values after I've applied the orientation matrix generated by the Sensor Manager. The third set contains values after I've smoothed the data with my own algorithm.

Android :: Is It Possible To Get Sensor Data At Regular Intervals?

Aug 2, 2010

Just joined the Android group. I'm having problems with the acceleration and orientation sensors.I would like to obtain sensor data (acceleration and orientation values) at regular intervals (10 milliseconds). However, the SensorEventListener doesn't allow you to do that. Does anyone have an idea of how to work around this issue? This is important as I need it to collect data for an app I'm working on.

Android :: Sensor Data Poll Mechanism

Jun 3, 2010

Per the current implementation in Sensor Manager, the SensorThread is polling data per below code, final int sensor = sensors_data_poll(values, status, timestamp); it then checks the sensor type if it is registered and processes the data further. For an application which has registered for only one sensor, still to get that particular sensor data, SensorThread has to execute for atleast N-1 loop most of the time. Can anybody provide the insight as to, why SensorThread is waiting to check the sensor type to be returned by the HAL instead of sending sensor information which is currently registered by that application. Wouldn't that increase the performance?

Android :: Latency When Getting Sensor Data From Phone?

Mar 9, 2010

I am working on a project using HTC magic which requires the data from the electronic compass, including both the accelerometer and magnetic sensor. But I find that there is a significant latency between the move of the phone and the trigger of the sensorChanged event. In other word, the acceleration and magnetic data obtained from sensor are updated about half of a second after my motion. And I have several questions about the problem as follow. Are the orientation data computed by the acceleration and magnetic data? Or are there a physical sensor for orientation? Does the latency result from the android API (using the event) or the physical limitation of the electronic compass? It is said that the model of the electronic compass is AK8976A from Asahi Kasei. Does anybody have the datasheet or know the frequency of the sampling? Any idea to improve the real-time experience?

Motorola :: Writing Android Sensor Data To XML File

Nov 9, 2010

I am developing an application that read data from sensors and write those data to an XML file when you press a key. i have 2 activity one for button and another is an Activity who implements sensorEventListener. the problem is my main activity is button and couldn't get data from event listener activity. i think the listener activity is not active but when i create an intent and start activity with that intent the program stop working. the button is able to create XML file solely.so how could i read sensor data from sensors,and how to send them to XML file when the button got clicks.

Android :: How To Use OnSensor Changed Sensor Data In Combination With OpenGL?

Nov 24, 2010

I have written a TestSuite to find out how to calculate the rotation angles from the data you get in SensorEventListener.onSensorChanged(). I really hope you can complete my solution to help people who will have the same problems like me. Here is the code, i think you will understand it after reading it. Feel free to change it, the main idea was to implement several methods to send the orientation angles to the opengl view or any other target which would need it. method 1 to 4 are working, they are directly sending the rotationMatrix to the OpenGl view. method 6 works now too, but i have no explanation why the rotation has to be done y x z.. all other methods are not working or buggy and i hope someone knows to get them working. i think the best method would be method 5 if it would work, because it would be the easiest to understand but i'm not sure how efficient it is. the complete code isn't optimized so i recommend to not use it as it is in your project. Code...

Android :: No Light Sensor / Proximity Sensor Detected On Hero?

Feb 8, 2010

I have a HTC Hero here, and when I tried to get the list of available sensors on the device by calling ((SensorManager) getSystemService (Context.SENSOR_SERVICE)) .getSensorList(Sensor.TYPE_ALL); I get only the following sensors: D/SensorManager( 6302): found sensor: BMA150 3-axis Accelerometer, handle=0 D/SensorManager( 6302): found sensor: AK8973 3-axis Magnetic field sensor, handle=1 D/SensorManager( 6302): found sensor: AK8973 Orientation sensor, handle=2 D/SensorManager( 6302): found sensor: AK8973 Temperature sensor, handle=3 According to the specs, there should be a light and a proximity sensor on the Hero, and I've seen it in action (the automatic screen brightness adjustment) - so at least the ambient light sensor is definitely there. My question is then, why doesn't the getSensorList return for me the light and the proximity sensors?

HTC Droid Eris :: My Home Sensor Is Not As Responsive As My Back Sensor

Feb 18, 2010

My home icon is way less responsive than the back icon which seems to be perfectly normal. Sometimes I have to "press" the home icon twice to get the "buzz" and have it move the screen. However the back icon works 99% of the time on the first press. IS there any adjustment I can make or should I bring the phone back. I have had it now for 2 weeks.

HTC Droid Eris :: My 3G Is Turned Off Even Though I Haven't Turned It Off

Jan 5, 2010

This is my first post and it comes with some questions:

First and foremost at random times my 3G is turned off even though I haven't turned it off...go into the setting and it says its still on. Only way to turn it back on is to turn it off and then turn it back on? Any ideas just a problem with the phone maybe. Didn't know if anyone has encountered this problem

Second is there and application that I can use that will let me select what things will startup with a reset of the phone? Also is there an easy way to reset the phone without a battery pull? I just like to do this when Unistalling apps and installing apps...always seems faster after downloading or Unistalling after I do this.

Android :: MotionEvent And KeyEvent Causing Excessive Garbage Collect (GC) Calls

Jan 3, 2010

I'm running into some issues with input events and garbage collection, or more precisely object allocation. I am creating a game and have pretty much got my head around the OpenGL environment. I've digested all the relevant material I could find regarding performance, memory allocation etc (and watched the excellent presentation by Chris Pruett - http://code.google.com/events/io/2009/sessions/WritingRealTimeGamesAn...). I've pretty much eliminated any object allocations after initial setup from my game (which is still in its infancy), but I'm still getting a bunch of GC calls, like this:...........................
