Android :: Physical Height / Altitude Device Using Sensors
Dec 8, 2009Anyone know if it's possible to obtain the physical height or altitude of your device, using the sensors or by any other means?

View 4 RepliesI need to know exactly how big the screen is on the device in real units of length so I can calculate the acceleration due to gravity in pixels per millisecond. Is there a method somewhere in the Android API for this?
View 2 Replies View RelatedJust started developing apps and am having a small problem. I can test the apps on the emulator but I cannot test them on my physical android device. When I am asked to select a running device I get a device listed as: Serial Number/name:? AVD name: N/A Target: unknown etc,
It seems that my device is being picked up but not able to be used. When I try to run the app I get an "Must set android.target.avd" error.
Is there something I am missing?
I am using netbeans 6.7.1 on Ubuntu 9.10, everything up to date. I have a G2-Touch from T-mobile, if someone tells me where to find it, I will post any other needed information.
I just got 'my first app' working on Eclipse, but I can't use my physical device as a target. I have Android 2.3 Gingerbread, Samsung Galaxy Ace(aka Cooper), Win 7. Latest versions of Eclipse and ADT. On adb devices, it doesn't show up, only the emulator if that's on.
USB Debugging is turned on and I downloaded three different drivers: the one Windows automatically downloads, one using USBDriverTool and the Universal ADB Driver.
If it's relevant, I also had trouble installing the ADT plugin with Eclipse, I posted about it here in a separate thread.
how to setup a infrared remote control to use with android instead of keyboard or mouse.I thought in lirc but the several ports that I found for android are working to send infrared signals, not to receive them.I was wondering if there is some project or program to allow infrared remote controller manage the android device.

I'm using this: DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); but width and height get swapped depending on orientation of the G1.

I have a problem creating a custom view for an Android application. My custom view wants to use if permitted the maximum screen width. I couldn't find any way to retrieve this value. Can anybody point me to the right method?
View 1 Replies View RelatedI want to get the width and height of my device to know what type device it is ie QVGA, HVGA ,WVGA.. Also i need to adjust some layouts according to width and height of the screen.
I tried following methods but its not working.
CODE:.........
All these methods return wrong width and height for the 240x320 devices namely Samsung Europa and Alcatel which i have. Width = 320 Height = 240.. This is wierd as some of the critical functionality is getting hampered .. I think this is really a basic thing which shd be correctly provided. Please help me with this issue .
I'm working on a project that includes a test system for OEM devices. The supporting infrastructure is complete, however I'm having difficulties getting ROMs to run on the emulator. Of course the AVDs generated by the SDK work fine, but my next step is to run a binary intended for an OEM device. I understand that the emulator would require different drivers than a physical device, so I can't simply drop the same binary onto it and expect it to run.
Tweaking the AVDs generated by the SDK is about the limit of my knowledge. I've looked into pulling the system.img and other partitions from the ROM with ones from the emulator, but that doesn't work since the emulated hardware doesn't match what the drivers expect. I assume some modifications to qemu and some reverse engineering of the OEM ROM might be required to obtain my goal.
Assuming I have access to the binaries (but not the source) used by an OEM to construct their ROMs, what would be involved to obtain an emulator that matches the physical device, so I can run the compiled ROM on the emulator?
I am writing an android application that has 3 views one below the other. Each view has to be of equal height, depending on the screen size. Each view occupies the full width of the screen. How do you specify in the layout xml that the view has to take up 1/3rd height of the device display height? What would be the appropriate layout to use in this case?

How can I get the body (second EditText) to fill the rest of the screen, but still have the scrollview kick in when the contents of the body are too long? Like a height="wrap_content" and minHeight="fill_parent"
layout_height="fill_parent" seems to not do anything if you put them in a scrollview
A working example of what I want is the email app compose window
I tried this and the EditText elements act like they are wrap_content and no filling is happening. Just scrolling if you type enough

This is my layout that suppot delete from listview ,the problem is when listview height is higher than screen height it goes under the button , so need a solution for avoding it
View 3 Replies View RelatedI want to put a button next to a EditText and I want their heights to match.For example, from the built in Android browser:
The Go button is the same height as the EditText field.I know I could wrap both these views in a parent layout view, and set both of their heights to fill_parent, and that would make them match.However, I would like to do this without having to give the layout a static size.I would rather have the EditText take whatever height it needs based on the font size and then have the button next to it match whatever height that might be.Is this possible with an xml layout?
I am having problem with a GridView within a RelativeLayout, which is again within a ScrollView. The problem is that the height of the RelativeLayout is not following the height of the contents of the GridView. When there are more than one rows, the GridView is clipped and a scrollbar appears, which is undesirable. I have tried to illustrate my problem using an screenshot from the Android hierarchy viewer. You can see how the red RelativeLayout box has clipped the second row of the GridView. I am pasting the XML layout of the page (page.xml) and the individual grid item (griditem.xml). I have used the following code to inflate the grid items in the gridAdapter code:
CODE:.................
What I should do to have the height of the RelativeLayout follow the full length of the gridView?

I know that the GPS altitude data isn't particularly reliable, so I looked for alternatives. This looks like a good solution I found here: But the value returned is not what I expected: -1.79769313486231E+308 I'm not sure what I'm supposed to do with this figure...

View 3 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 2 Replies View RelatedI 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?

Can I assume the sensors on devices such as the G1 are fairly accurate or can I expect to run into problems such as the compass being 5-10 degress off etc?
View 4 Replies View RelatedI 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?
The 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?
