Vibration Analysis On Android
Feb 19, 2014
I want to develop a Vibration Analysis application. I want to use it to measure the vibration in an Elevator so one can analyze the riding comfort.
First, the phone will be put on the flooring in the middle of the cabin, the measurement should be along the Elevator's total travel (up to 1min ride) and at least following to 2 axis (X and Y, if I can measure following Z too, it will be great). Once those data are captured during this 1min, I want to plot them on a separate graphs (first graph: X position vs time, second graph: Y position vs time). Also, I might add the feature of measuring the elevator speed while traveling inside the cabin.
My questions are:
1- Can I get the data that I want only from the accelerometer? or I should use the gyroscope and the digital campus as well?
2- Can the accelerometer (on Samsung Note 2 for example) detect small vibrations? like ones that occurs in an elevator (around 15 m-g)

Is there a way to alter the intensity of vibration or the type of vibration for different notifications? Same goes for the LED light

My question is basically "can anyone recommend an application that will tell me which applications are draining my battery". I've read about task killers and usage and turning stuff on and off, I'm not worried about that, and I don't need to know why (i.e Google Earth uses X units per hour.

is possible to analyze audio stream spectrum with Android API (similar to what you can easily do with Flash). Basically what I need is to determine the duration between two claps in a small audio record. The claps are much louder than the background, so theoretically it should be somehow possible..

As the world cup is the main sport event and the Vuvuzelas are the most annoying sound in the world, I had an idea to remove them definitively by reading this new ( http://www.popsci.com/diy/article/2010-06/simple-software-can-filter-out-vuvuzela-whine) that told us that the sound has some frequencies at 233Hz + 466,932,1864Hz.
I have already made a lot of Android application by myself but never touching the signal analysis and filtering part, so here are a few questions, I do not ask for precise answer but maybe links and tutorial to find something to work on. I guess that a new Android phone has the CPU and power to make real-time filtering.
1) How can I intercept the sound coming from the Jack microphone - Line-IN plug- ( I plan to link my TV to my phone with Jack to Jack plug). My question is totally software and coding, I have all the wires and adapters to plug a jack into my android phone Line IN.
2) Are there some Fourier analysis librairies, may I have a look to Java libraries on the web and import them to my Android project?

I want to know what kind of users are using my app.
I think I need the device id, the network type, the network provider name and its ip address. is there any framework to do this thing? And of course I will ask user to enable it before I can do it and leave an option to disable it when user want to toggle it off.

I was playing around with some of the live wallpapers and thought it'd be neat to try to make something like the frequency/waveform visualization wallpapers, but I'm not sure there's an API to get the audio output data from the device. I know you can use AudioRecords to get this sort of data from microphones. Anyone know if there's a way to manage it for a device's output?

I am a golf professional from Pennsylvania. I am looking for an app that I can:
-Record and import videos taken w/ the Droid
-Slowmotion Playback (forward and reverse)
-Frame by Frame Playback (forward and reverse)
-Save clips by video angle (down the line, face on, etc)
-Ability to draw lines/shapes on the screen w/ various drawing tools. If anyone has any interest, please let me know. I am not sure how to go about developing this type of stuff, so anyone who can provide some insight, it would be much appreciated.

I am looking for some help. I'm new to android, and java development. I've got a pretty good handle on the basics, but I'm having an issue figuring out some more advanced operations. I'm working a guitar tuner, which is a stepping stone to a chromatic piano tuner. There is no public API for frequency analysis, so I'm thinking I need to write into code a Fast Fourier Transform, and I'll assume I need to import a different package for this. Once I display the frequency of any given note, I need it to reference it's offset to a pre-measured Mhz. There is alot to write, I'm aware, but my first step is to try to figure out HOW to get the frequency, and display it in the UI.

Now I'm not a professional reviewer, but I think I have some good insight to share. Also you may be wondering why this is in the EVO 4G forum, well the EVO is considered one of the best phones out there and I happen to own an EVO myself. I think the phone is great, but I'm usually critical of my devices and I like to take a look at the keyboard as I'm an avid texter. I see a lot of posts of people wondering why one keyboard is not as accurate as another phone. If you're a big texter and you're looking for a really good text phone, I promise this is a good read. So what makes the best touch QWERTY keyboard? Well we would have to look at the criteria of what makes the best QWERTY keyboard:
Keyboard layout
Capacitive touch screen quality
Multitouch
Accuracy of predictive text
If a phone can do all of these things perfectly, you'll have a phone that will be a texting monster. Lets take a look at what I think is the most important criteria, keyboard layout.
Portrait Keyboard Layout
Unfortunately, I think the EVO comes in last for keyboard layout. It has the largest screen, but it wastes most of it with its oversized cursor buttons. The cursor buttons need to be smaller for the other keys to breathe and need to be in a D-Pad layout. If the keyboard is top notch, we shouldn't be using the cursor keys so frequently to fix errors. Also why the keyboard takes up 2/3 of the screen confuses me. This is purely opinion, but I would rather have the "hide keyboard" button not take up space and move it in the upper right like the Nexus One and iPhone as a "Done" button. Lastly the EVO has the shortest "width wise" space bar. The space bar is used frequently and shouldn't be gimped like that. So that leaves the Nexus 1 and iPhone. If you look closely, the iPhone has the most space between keys. Most typing errors are from keys being so close together and hitting the wrong key.
The EVO faces the same problem, although the keys are bigger, so are the keys that are right next to it. Bottom line, keys not only need to be bigger, they need more breathing room in between each other. Another close detail is the "q" and "p" key. The EVO has those keys farther away from the edge of the screen than the iPhone and Nexus 1. The edge of the screen is the least responsive area, so is this space a benefit or a negative? My take on it is that one of two things happen, you either hit the neighboring key, or the key doesn't register at all. If you hit the neighboring key, it takes much longer to edit, rather than to just try and hit the key again. So even though the edge is less responsive, its more beneficial to have the "q" and "p" key closer to the edge and away from its neighboring key. Portrait Keyboard layout goes to iPhone, 2nd Nexus1, 3rd EVO 4G
Landscape Keyboard Layout
Next is landscape mode. I thought this deserved to be addressed as it changes everything. Although the iPhone still has more space between the keys, I'm gonna have to give this landscape mode to the EVO. Unfortunately the space bar on the EVO is STILL the shortest out of the three. So why does landscape make such a big difference even though the keys on the EVO are tightly packed? Well the difference is that the keys are now squares, instead of thin rectangles. This increases accuracy a lot and pretty much negates the disadvantages of having narrow spaces in between the keys. Again HTC could of capitalized on more space for the general keys by not taking up so much space with the cursor keys. As for the Nexus1, the keys are slightly bigger than the iPhone, but are still really tightly packed, so I would say its a tie.
Landscape mode goes to EVO, tie for iPhone and Nexus 1
Capacitive Touch Screen Quality
What good is a keyboard if the screen can't even read your touch actions? I know that the EVO is not tested in this, but we can still use this as a base of comparison. I really believe that the quality of the screen plays a very big role in the responsiveness of your touch actions. Nothing is more annoying then having your touch actions not being registered correctly or not at all. Right off the bat, the Nexus1 is out. So its now the iPhone and EVO 4G. From what I have read, but I can't seem to find the article. The EVO 4G uses a much higher quality capacitive touch screen compared to the Nexus1, most likely very close to the iPhone. So I'll say its a tie between the EVO and iPhone.
Capacitive Touch Screen quality goes to, EVO 4G/iPhone tie, 2nd Nexus 1.
Multitouch
With a multitouch keyboard you're able to type faster. All those fast typers out there can really appreciate a multitouch keyboard. I'm not sure if the Nexus1 supports this, but I don't think it does, so correct me if I'm wrong. So in this case you either have multitouch keyboard or you don't and the iPhone is the only one to have it.
Multitouch goes to iPhone, tie for EVO 4G and Nexus1
Accuracy of Predictive Text
I don't have any experience in this on the Nexus1, but only on the EVO 4G and iPhone. So anyone can chime in if I'm incorrect on this matter. I would think the EVO and Nexus1 would be the same considering they're both Android devices. From my experience and watching many videos, it seems like the iPhone does a better job at correcting and predicting text input compared to the EVO.
Predictive text goes to the iPhone, tie for EVO 4G/Nexus1
Misc
So the last thing I think all the phones adds a little something to make texting easier that doesn't quite fit the criteria. The iPhone OS has a pretty neat magnifying glass where you can move the cursor. I found this extremely handy. The EVO 4G has the cursor buttons instead, which isn't as slick, but can prove to be more precise. Then finally both the EVO 4G and Nexus1 has the voice to text feature from Google, which is pretty dang accurate.
MISC goes to the EVO 4G, tie for iPhone/Nexus1
So what phone do you think has the best, most accurate touch QWERTY keyboard? Is it one of these three, or another phone out there. Also what do you think makes the best touch QWERTY keyboard phone? I appreciate those who took the time to read, took me a while to type up.

My phone was rooted with the 2.2 firmware everything was working fine and yesterday by itself the phone shut off when i tried to boot it, stays in the samsung galaxy boot screen. I tried going into download by holding vol+home+power but it says POWER RESET or UNKNOWN UPLOAD MODE. The phone is able to connect with my pc I tried flashing 2.2 Froyo with odin3 but its stuck at File analysis. Is there any way to fix this? I cant return the phone I bought it unlocked off ebay.

I saw this question asked before with no answer (a post in April) so I thought I would ask again. Does anyone know of an app that will allow vibration for e-mail notifications when phone is set to vibrate? This has always bothered me about a device that I otherwise think is just an outstanding piece of equipment. If anyone has an idea I would GREATLY appreciate it.

Android doesn't seem to recognize when I am on the phone. While on a call, it still vibrates when I get a text or e-mail. It is loud and annoying. When not on vibrate, it still plays the message received tone, and it is loud too. Has anyone else experienced this issue?

I am trying to use vibration alert with notification and flash lights within a service.
I wrote the following code:
CODE:..............
But when I run my application, I get the following error:
CODE:..........
In the manifest file I have added the following lines in manifest, application, activity and the service element:
CODE:.............
But I am still getting the error. It is obvious that I am making some mistake defining the permissions. Can anyone tell me what I am doing wrong? I am using Android 1.5_r3.

I have created an application that creates notifications, using the following code:
// Notification notification = new Notification(R.drawable.notification_icon, title, System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// parameters
String ringtone = prefs.getString(context.getString(R.string.key_notifications_ringtone), "");
if (ringtone.length() > 0) { notification.sound = Uri.parse(ringtone);
notification.audioStreamType = AudioManager.STREAM_NOTIFICATION;
} boolean useVibrator = prefs.getBoolean(context.getString(R.string.key_notifications_use_vibrator), false);
if (useVibrator) { notification.defaults |= Notification.DEFAULT_VIBRATE;
} boolean useLed = prefs.getBoolean(context.getString(R.string.key_notifications_use_led), false);
if (useLed) { notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
} // alert
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.notification);
contentView.setImageViewResource(R.id.notification_icon, R.drawable.icon);
contentView.setTextViewText(R.id.notification_title, title);
contentView.setTextViewText(R.id.notification_text, text);
notification.contentView = contentView;
Intent notificationIntent = new Intent(context, MyActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.contentIntent = contentIntent; notificationManager.notify(1, notification);
The notification works, and the correct ringtone is used. However, even though the preferences are correctly activated and notification flags are correctly set (I checked by debugging), the notification never vibrates and never cause the lights to be activated. I would have blamed my phone's settings, but every other app using notifications, like messaging, gmail, and others correctly use all these features. (My phone is a HTC Hero with Android 2.1)

So I am trying to simulate that the phone is receiving a call. I have successfully extracted the phones ring tone and played it. Now I want to simulate the vibration. While I can make the phone vibrate, I want to emulate the exact pattern that the phone vibrates with as when it receives a call. Is there some setting or class that I can use to extract this pattern, and also detect if vibration is turned on?

I just got G1 phone and I think its awesome. The biggest weakness on this phone is vibration. Even I put G1 phone o my computer desk next to me. I cant feel a thing seriously but with my old Blackberry I can. I really need it badly since I am deaf. I found a funny app called Vibrator and vibration actually can last longer than the notification setup. I figure someone can help me setup fast and simple apps that allows us to tweak vibration to be stronger. I know Blackberry has range 1 to 10, let me decide what works best for me. How do I formally request Android Team or Google/TMO to look at it?

Is there a application or a way to have the phone vibrate but have messages come in silently? Sometimes I need to have alerts silent, and be able to tell that there is a phone call, other times I need to have both message alerts and phone calls be audible. I'm looking for a way to quickly do this.

One little thing I miss on my Blackberry was that I had it set to vibrate once for Social Network notifications, twice for an email and three times for an SMS. That way I knew how important it might be and whether to take it out of my pocket. My T-Mobile G2/HTC Hero (1.5) doesn't seem to have the option to change the default "vibrate twice". Is there any way of changing it? Or an app that might do it?

I've been working on a game framework for a little while, and while its far from perfect, I've put the current version online. To be honest, I haven't used much OpenGL in the past. Before last week I had never tried using it. If anyone would like to take a look, please do, I'd appreciate all the help possible on speeding it up. There are many features I have in mind and am planning at the minute, but so far it supports:
# Texture and Sprite management # Text, using TTF fonts # Organised layers # Two audio management classes, one optimized for music, the other for sound effects # Sprite dynamics (acceleration, terminal velocity, collisions) # Animation # Handlers to manage events fired through movement, animation, screen touches, accelerometer input, device shaking and collisions # Several minor features aimed at speeding development, such as screen settings and vibration.

I wrote some code that mute the phone whenever an incoming call is received.
When the phone in vibrate mode I use the following code to stop the phone vibration:
Vibrator vib = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
vib.cancel();
While it worked on my Nexus One with android 2.1, it seems that it doesn't stop the vibration on an HTC Desire handset with android 2.1.
Have someone encountered this issue?

This in regards to its vibration function. due to the rather soft tone of its sound (to me at least) sometimes when my phone is ringing from a message, i tend to NOT notice that a message comes in. so i use vibration , but the thing with hand cent vibration is the vibration is a one time thing only. a message comes in, it vibrates once, and thats it.. but the ring tone goes on and on.. fiddling with the vibration settings in hand cent did not help. what i want to do is make my desire vibrate a lot more times than just
once.. is this possible?
