General :: Rotation Sensor Switching Application
Feb 7, 2012
I'm just wondering if there is currently an app out there that allows certain applications to use the rotation sensor on our phones, but not other applications.
For instance i like to text message in landscape mode sometimes but when i go to my home screen and tilt my phone at all, the home screen will go to landscape which i don't like because it takes a long time to switch back and forth between portrait and landscape and seems to be overly sensitive to the axis of my phone.
Does this application exist? If not, how hard would it be to create?

I'm trying to figure out exactly how to interpret the rotation angles produced by a Sensor Event for Sensor.TYPE_ORIENTATION. Unfortunately, the documentation (http://developer.android.com/reference/android/ hardware/Sensor Event.html#values) doesn't give a complete definition of it. It defines what the axes are, but doesn't specify what order the three rotations are applied in, nor whether the later rotations are around transformed or untransformed axes. Without knowing that, it's impossible to know what the actual rotation is that's being described.

I'd like rotate the screen to put it upside down. Can I do that with android API? I was told by some friends that there are APIs to rotate the screen by 90 degree but I can't find a way to rotate the screen by 180 degree (upside down).

I know the Android SDK provides many Sensor class to use to get data or do something. I already verified my driver of sensor to get data successfully under linux kernel-2.6.29 I use I2C protocol to communication with my device, so I put sensor code under drivers/i2c/chips NOW I want to add my sensor into Android and I hope to link Android Sensor class with my device to reduce develop my application. How to do for this goal? Could I need to modify application framework or Libraries or another driver type for new device? I big your help

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?

Does anyone know the difference between the orientation sensor and magnetic field sensor on Android?Since I've read that magnetometer is synonymous with digital compass I'm a little bit confused. What are they really?

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.

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

I've got a problem with meebo IM. When I start it its icon appears in the top left on the notification bar, which is ok. But when I'm done chatting, how do I close it? back doesn't work, home doesn't work. I even downloaded the terminal but couldn't kill it with that either. Is that a bug in meebo or is android just like that (no closing of apps)?

Switching off Wi-Fi via an application (in this case WiFi On/Off or Power Manager) turns the phone into Airplane Mode = No Cellular Voice or Data. Cure..turn off Airplane Mode under settings and cycle power on phone.

I bought a generic tablet. A Boxchip A13@ 1.2Ghz, GPU Mali400,, 512Ram.. etc.
The thing is I flashed it with a compatible rom, but some configurations are wrong.I got wrong button mapping, and aI solved it, but Not the strangest thing happens... it seems the configuration of rotation is allways a step behind.
having 4 possible positons (Portrait, Upside down portrait, Landscape and Upside down landscape),When I put it n the poision of landscape, the screen rotates to upside down portrait. In upside down portrait to upside down landscape, in upside down landsacpe goes to portrait, and in portrait it goes to landscape. It's driving me nuts! haha I temporarily disabled rotation, but It's a nice thing to have enabled.. In conclusion, It seems the configuration somehow maps the position +90 degrees clockwise more than it should. Where is it maped?

it is possible to use auto-rotate in this rom, or if the developer is working on it? Really nice ROM, and it will fill the bill for my new A210, but would like to use auto-rotate and hopefully be able to use a Trebuchet style launcher.

What are the codes in framework that affects rotation? Basically, the problem I face here is, even after enabling in Settings>Display>Rotation>0 degree and 90 degree, the display does not go to landscape even after I rotate my phone.
I am running Android 4.1.1

Is there a trick to use the gyroscope instead accelerometer to rotate the screen? Or, is there any "Hack" to improve rotating speed? iPad have a very nice rotation.
Btw, I have Galaxy S2.

I've got a Samsung Galaxy III and have problems trying to view images in my gallery using the auto-rotate screen option and rather then having to manuallly press the rotate screen "icon" which does gets annoying. I just want to tilt my phone so the images can automatically change to portrait or landscape on its own depending what angle the phone tilts. I've ensure the auto-rotate screen is checked from Settings under Display and even tried unchecking it and checking it again as well as switching my phone on/off.
NOTE: That the auto-rotate screen option does work fine for me with everything else like watching videos, texting, internet browsing, music and even viewing the overall images in the gallery but when going in and viewing the pictures individually from either the Gallery or the Camera. All I've got is a rotate screen "icon" to press on manually each time I'd like the picture to be portrait and if I want landscape I have to press on the screen rotate icon again. I noticed the auto-rotate screen option doesn't work on my Home Screen and Lock Screen as well but that isn't the main issue.
I've been reading around and tried pulling out my battery on "Odin" mode, wait 30sec-1min then turn my phone on again and that didn't work. I've also did the same procedure and ensure I unchecked the auto-rotate screen option and checked it again after I turned on the phone. I tried the Gyroscope Caliberation option and calibrated it and that didn't work either. My sister has the same phone as me with the same version installed but she doesn't have this problem and I'm wondering if it's something to do with how my phone software's set up?

How to make screen mirror like as apsis coordinate...???
I tried:
Code:
persist.hwc.mirroring.enabled=1
persist.hwc.mirroring.transform=1
For example:
< | >
I found how to rotate manually:
Code:
Set in build.prob -> ro.sf.hwrotation = 0 for 0, 1 for 90, 2 for 180, 3 for 270 which you want...
But I need to mirror effect on all based android system

Somedays back My phone just got stuck at the boot animation... So I restored it to its factory rom: upai_n9880I stock rom: 20120804_e1811_v75_jbaol1_g88. But when I went using the camera, the camera was inverted and if I turn in to lanscape, it would rotate but get inverted like in portrait mode. Now the games were also working flipped... The guy in Temple run now turns right if I tilt to the left and so forth.
So I tried flashing the phone with Taiwan upai N9880_ICS_V.01... but the issue remains. I tried reformat the flash and re-installed Taiwan Rom... the issue remians.

All the level/bublle app's show's horizontal rotation but no vertical.

Ok... So, is there anyway to force rotation-lock to turn off on a Nexus 7 with Android 4.2.2?
Reason: I cracked my screen from the bottom left of the screen to just shy of the top right corner. The lower section, below the crack, is not responsive to touch... and the dots I need (I use the pattern pass) are on this side because I can't flip the tablet.
How This Happened: I turned on rotation lock with the tablet upside down to keep it there... But then my Nexus 7 decided to restart randomly and keep rotation-lock on but coming back in the default orientation, aka the wrong way that I need it to be.
