I am looking for a way to get sensors' data ( especially Accelerometer) directly without using Listener approach. Actually I need to have the data really fast! I can not find any way to read sensor data by myself. Anybody knows anything about it? Is it possible to read data with more than 50Hz?

I have following code:
CODE:...........
Code is working but here goes my problem: when I call it from main activity in this way:
CODE:........
Then i can see 10 times result of 'doing sth else!!!' and when loop is over i can see then result from activity. So sensor activity waits for some reason and then when main activity has nothing to do, sensors are doing their job.
of course I have well implemented: onActivityResult(int requestCode, int resultCode, Intent intent)
I want to read sensord data directly, not using listeners, is it possible?
Is there a command that i can access directly a key into an application? I don't wanna capture when user press the key, i wanna access it without press.

View 1 Replies View RelatedI'm still pretty new to using Android, but I decided that my first application would be a simple flashlight app for my new Incredible. Unfortunately, it seems to be more difficult than I had originally thought.
It seems that there's no way to access the LEDs through the SDK, at least not without a bunch of weird hacks to make the phone pretend that it's taking a picture. Even then, I can only get the LEDs to turn on. They only turn off if the phone is put on hold, and doing so breaks all camera-related apps until the phone is rebooted.
So, I was wondering if accessing the LEDs through the NDK was possible, or if there was any other camera-related APIs that would seem to do what I want.
I've looked at other code for other flashlights, so it looks like it's a hardware-based problem. I figured I'd give up because it doesn't appear to be possible, but I thought I should ask here first on the off-chance somebody knows something that I don't.

View 4 Replies View RelatedHad my phone two days and I've already managed to screw it up. Gmail through the browser works fine. Notifications of new mail work fine; I can pull down the notifications bar up top, click on the mail note, and read/mark everything fine from there. But I'm screwed once I exit that. See, I can't just access gmail directly through the app. If I click on it, I get a black screen saying "your mail will appear shortly" and a note in the bar up top saying "waiting for sync". Just cleared Gmail data.
View 4 Replies View RelatedI have a ListView whose position should be changed automatically along with the data. So, when the adapter's data has changed (adapter is calling notifyDataSetInvalidated), I'm calling setSelection. This has no effect. If the call to setSelection is done later (e.g. in a click handler) it is working.
The second problem is, that the ListView maintains the scroll position of the list although the data is completely invalidated, that makes no sense IMO.
It looks like a call to layoutChildren before the call to setSelection does help in this case, but layoutChildren is protected.
What is the correct way to do this?
I have a generic (unbranded) tablet here. The user has used too many pattern attempts. I do a lot of these where I just wipe the device for people.
Sometimes I use key combos and sometimes i use ADB to boot into recovery and then simply select the "wipe data / factory reset option"
However, this tablet has no keys , no volume keys that is, so i used ADB to boot it into recovery which it did just fine.
How can i select "wipe data" when i can't use volume keys to select it? the touch screen is unresponsive in this mode too
I have tried
ADB SHELL WIPE DATA
but i get a permission denied error
I have tried running
ADB ROOT
but i get a "cannot run as root in production build" error
I have tried to root the tablet with super one click by short fuse but it crashes.
so i am basically asking is it at all possible to do a wipe data / factory reset on a device which is not rooted through ADB?
Is it possible to write data directly from my phone to my micro SD card? I got my Captivate a couple days ago, and I've been trying to research as much as I can about it, but I can't find this info.

View 20 Replies View RelatedA simple question: How do I register for multiple sensors? I just switched from registerListener(SensorListener listener, int sensors, int rate), which is deprecated, to registerListener(SensorEventListener listener, Sensor sensor, int rate). Previously, I could use " | " to indicate multiple sensors, but now " | " is undefined, so how?
View 4 Replies View RelatedI'm programming an Augmented Reality application. It's development it's in an advanced state but I can't place the icons on the screen so still as anothers programs does (Layar, in example). This is because of the continuous variations of the sensors. I've tried the three modes of the sensors (FAST, GAME, and NORMAL) but I only get them to move more or less fast. The shivering is the same at different speed.
Finally I thougth I could reach my goal with a digital filter, averaging historical values. But again the icons continues moving, specially the most far placed ones (in the z axis). Please, could some one help me with some clue?
Last night i have downloaded Dolphin to play Wii Games. As you can imagine, play with the mouse is not as comfortable to emulate Wiiremote.
My idea is basically:
Control WII emulator with Android Sensors (As accelerometer, gyroscope, inclinometer) like Wiimote does
It seems to be quite interesting, I think that may be connectable by wifi and bluetooth with receiver (pc).
We are supposed to make UI actions only from the main UI thread. But it is not clear to me if callbacks like LocationUpdateListener (and other callbacks from sensors) are already in the UI thread or they require special care to access the UI components.

View 4 Replies View RelatedThe accelerometer turns off when the screen is off. I'm guessing this is a bug but I haven't seen it logged. Am I missing something?
Perhaps the power management features need some improvement - the ability to specify what components are needed during a partial_wake_lock so that power can be conserved as efficiently as possible.
BTW, there is a bug logged noting that onSensorChanged() continues to be called for the orientation sensor (during sleep) but the values are not being updated.
I can't seem to find this info on the droids temperature sensor (the one available in the SDK):
Does it indicate ambient temperature or is it the temperature of the phone or chip?
Also, does the pressure sensor indicate atmospheric pressure?
I am having a difficult time figuring out a way to read the sensor data from a home screen widget. I can successfully create a home screen widget that extends AppWidgetProvider. I can successfully create a stand-alone application that reads sensor data (extends Activity). What seems to be impossble (for me) is combining them into a home screen widget that reads sensor data. The classes that you have to use, like SensorManager, SensorListener all seem to require an Activity which the AppWidgetProdiver doesnt have. I have also tried keeping my sensor data reader in a separate class that extends Activity and then instantiating that class in my widget. Makes sense in my head but no data is ever read from the sensors.

View 3 Replies View RelatedI am developing an application with TripIt integration and I make a call to their API and I get all my data in JSON format and save it in an object ListTripResponse. This object contains all the data I need over all the application. What I do now, I write this object to a text file (i serialize my object and save it as a file with ObjectOutputStream) and in every activity I read this file. But this file is pretty long and it takes a while to read it. And i have to use and read this object in every activity! Isn't there a better way to do this? I cannot save this file in a database because the structure is to complex.
