I'm interested in developing some software for the android OS using acceleration sensor and I would like to know how precise this technology is in mobile phones ? so I wont be waiting my time.If anyone know something please share!

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?

View 1 Replies View RelatedOr it's just some virtual sensor the uses the data provided by the accelerometer and the magnetic field sensor to calculate the orientation?

View 2 Replies View RelatedMy 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.
View 9 Replies View RelatedI 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?

View 4 Replies View RelatedI'm new to android development and I'm implementing a simple localization method to get used to the device. I've been reading some articles and I can't seem to figure out how the phone figures out sensor accuracy. My guess is that it decides this based on how long its been since it was last calibrated.

View 2 Replies View RelatedI had a discussion with a few of the Android team member at Google IO, and I'd like to throw the idea out here for general brainstorming with the community. My view is that it is not a good approach to create "sensor-specific" APIs with iterative releases of the Android platform and SDK's. By this, I mean that instead of adding a "location API", and an "accelerometer API", and whatever comes next, we should create a "generic" sensor API that can work with a broad range of sensor types, including sensor configuration, demand read/write/configuration, event notifications, and other functions. In this way, 3rd parties could also add innovative sensing capabilities (or external sensors) to their Android devices which would be "instantly" supported by the platform. Well-known sensor such as collocation and acceleration could have agreed-to sensor names/namespaces, with full extensibility for additional sensor types. As an example, collocation as a 2D longitude/latitude is fine for some apps, but for "inside the building" applications or for other apps involving the need to accurate location of people or resources in 3 dimensions, it doesn't cut it. Additionally, one can easily envision inclusion of RFID, environmental, and other sensors in devices that could dramatically enhance the capabilities of Android applications.

I've seen the Open Intents applications, but I'd rather use the raw Android API, at least until I understand it a little better. I'm surprised at the lack of documentation.
I am writing an application that initially will be developed as web (probably Silverlight) and Android application. I found on Android website that SQLite is supported, but I plan to release the same app for Windows Mobile, Palm Web OS and iPhone as well.Could you please advice me on which database would be the best to work with for all platforms?EDIT:Maybe I should add that I would want all applications (mobile/desktop) to connect to a main server when internet connection is detected and synchronize all data that's changed.

View 4 Replies View RelatedI've got an HTC Desire which has a Mobile Hotspot App on it - so I can connect my laptop to the WiFi signal generated by my phone.I have "Unlimited Internet" with a fair-usage cap of 1GB. (such a farce, that use of the word unlimited, why don't they just say 1GB?)However, the terms and conditions explicitly disallow using the phone as a modem.My question is, can they tell, and if so, how? Surely the HTTP/HTTPS requests being sent out by the phone are exactly the same, regardless of whether it's coming from the phone or the laptop?If they aren't (perhaps some ID which says this is a phone as apposed to a different ID which will be sent by the laptop's browser), is there a way to make it look as if the requests being sent are coming from the phone?

I am currently working with a HTC G1 and I am trying to retrieve my GPS position. But I can not understand very well the documentation. I wrote those lines, but they didn't work.It already write "provider == null" so I guess that "mgr.getBestProvider(new Criteria(), true);" returns null.
