Can anybody tell me about the current state of echo cancellation in Android? Are the functions automatically applied to microphone input? Can I use it, or is it applied automatically? I presume it uses OSLEC? Is this correct?

Yes, I can get sensor update events with SensorEventListener. But this approach has 2 drwwbacks:
1) For some sensors I have to wait for the state to update. For example, temperature may update after a minute!
2) In some cases I can get incorrect readings. For example, the phone lies on a flat surface and does not move. I receive first orientation update event after listener registration. When only a part of the orientation vector changes, other parts may be 0. And it is no way to determine, is it a true 0 degree azimuth or just an incomplete vector. If I move the phone a little, the correct non-zero azimuth appears.
To solve this problems it's possible to create a separate thread that constantly monitors sensors. After some time it will certainly contain true values. But I think that it is an overhead for such simple task.
Is it any other way to get current sensor data?
I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking.

View 23 Replies View RelatedI am trying to save some values in the onSaveInstanceState(Bundle) method of my activty by following the example here: How do I save an Android application's state?
But it doesnt seem to load it from the Oncreate(). the bundle object is always null but whenever i call another activity, it does indeed go into the onSaveInstanceState method to save my values.
Now i read that question i just posted and someone noted how they could not get it to work in an emulator? unfortunately that is all im working on. On an emulator and cant test the app on the device as i have no device available to me right now And the web services i am interacting with are in a local VM on my work machine that cannot be accesses remotely at the moment.
My question is, is it true that saved bundles dont work on emulators? I also noticed how when i do dismiss or bring up a new activity , the activity calles onPause and then onStop. when i bring back the same activty, it goes straight to onCreate?
now according to the docs here http://developer.android.com/guide/topics/fundamentals.html#actlife That is correct in terms of what the lifecycle diagram shows but if you read below that diagram on the onStop() section it says the next step it goes into is either onRestart() or onDestroy()? no mention of onCreate? Type on the docs?
Anyways here is my onSaveInstanceState() and onCreate() both in the same activity: code...
I'm developing an application which allows user to edit an image and save that edited image as new image on sd card I want to get the current state of the canvas object.
View 2 Replies View RelatedMy applications carries on processing when the user presses the home key, and generates status bar notifications if something happens the user requested to be notified about.
If a user holds the home key and then selects the application, it is restored in its correct state with the activity on top that showed when the user left.
However, since the intent that is associated with the status bar notification is FLAG_ACTIVITY_NEW_TASK and I put in the class name of the activity that launched the application (I assume this is what I must do?), the launcher activity is started when the notification is "clicked". I can then switch the application back to the current activity by starting that "active" activity again, but then I seem to have two instances of the activity in memory, since I have to press back twice to leave it. And I suspect my activity stack is then messed up as well.
I have set the launcher activity to be singleTask, but that only helped a bit. From my reading I thought this would just give the task focus if the launcher activity is not on top, but instead it gives the launcher activity the focus.
Is there a way for a notification click to work more like the task switcher provided by long pressing the home button?

I recently rooted and am having issues with my current ROM. My question is, can someone tell me how to do a backup of its current state now. So that way i can try a different ROM. And if its worse i would be able to go back to this one right?
View 3 Replies View RelatedWhen I do factory reset (which means the same as 'wipe', right?) it does resetting current installed ROM to its original state, right?
So, let's say I am doing factory reset the first time (so currently my phone has store ROM installed) so factory reset will revert all the changes in the installed ROM (such as settings, installed apps, all the data) to its original state - which the phone had since it got ROM installed.
But If I got root (which means I replaced secured kernel with unsecured one) and I installed another customized ROM and for some reason I want to do factory reset again - what's gonna happen?
Will factory reset revert original store ROM back or it will revert manually installed ROM (customized ROM) to its after installation?
And as far as I understood factory reset does nothing with kernel? It only affects ROM? So in the second case , when I use non-store ROM and I am doing factory reset - nothing will happen with my unsecured kernel?
I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?
View 1 Replies View RelatedI'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?
View 2 Replies View RelatedA couple of weeks ago I uploaded one of App which happens to be a widget. But from the time I uploaded it I have seen lots of cancellation. The only reason google gives me is this: You canceled this order. Reason: Other (describe below) Message sent to customer: Cancellation requested from phone.
I cant get heads or tail of it. What should I understand from this? There are no feedback, neither any ratings. Who is "YOU" here? I suppose this is not a programming question but this has raised after a lot of programming. Did anyone else also get something like this from Google and know what it exactly means?
Has anyone tried the cancellation method for getting an alternate android phone from tmobile?(you know, when you say, I'm sooo upset with my phone that I'm going to cancel my phone service, and they say "Is there anything we can do to make it better" and we say, "Yes, get me another android phone", and they say, "OK")
View 29 Replies View RelatedIn the last couple weeks I have started experiencing echo on my phone. Everything I say comes back to me and the other end can't hear anything. Sometimes it will take 3 or 4 calls before it starts working again. Tried figuring out if it's a specific area (which it appeared to be) but now it's worse and happening all over the place. Haven't seen/installed any updates lately, anyone else experiencing this? Next step is to stop by or call Sprint this week. Phone I believe is a version 1 f(got it on launch day).

I have a Kyocera Echo which has decided to forever loop in the start up instead of doing anything and since I can't hold power and volume down to factory restart I thought it was dusted
but if i read this thread correctly, HTML Code:
[URL]
I might be able to do a hard rest through fastboot.
I have installed, all the drivers from the Kyocera website, I have the sdk, I know where to go into command prompt, etc. But my phone is not being detected by the fastboot tool. when I type Fastboot devices, I get nothing, not even the ? mark they mentioned and it just hangs on when I do fastboot -w saying it's waiting for the the device.
Even though its looping my computer will detect the phone and when I have placed it in what i think is download mood (power + plus both volume buttons) it has detected the right drivers to install and though it loops will kind of pop up the phone on my computer.
But when I put it it in what I guess is fastboot mode (power + volume up) Window's says it found new hardware, "Android," just plain android. I tried to direct to install the usb drivers from the Android-sdk/extras/ folder, but that doesn't work and Window is not finding anything automatically.
I assume the problem is that I need to find the right driver for the "Android," but I can't seem to figure what driver that is.
I have a problem with my Atrix HD running ProBam 4.3 rom. My phone is ok but everyone I call or call me will hear an echo of his own voice making it extremely hard to understand the conversation. I didn't had this problem before on my first flashed.

Was reading a review at AnandTech and it says: On the left are the volume rocker button and a port for the secondary microphone for noise cancellation. You can follow that port inside to a small chamber where the microphone is. There aren't any markers on the volume rocker - then again up and down are pretty obvious. The volume rocker is also a multipurpose zoom control in the browser and camera application, which is probably part of why it's left unmarked. Here is the link if you wanna check it out.

View 10 Replies View RelatedI could swear I had de-selected a "noise cancellation" option in a menue somewhere in an effort to get my Droid to sound better during calls, but i can't for my life find it.

Calls still sound like crap to me, but at least people can hear me better, I think. Anyway, if there's the noise cancellation opt and I wasn't dreaming or severely confused, can someone point me in the direction of that?

View 4 Replies View RelatedI have a question about the noise cancellation on different ROMS - basically, I tested it after I rooted and went to Rubix focused (the latest one) and the feature is gone. I have looked and looked and really don't see anything about it. The test: I used my television volume numbers, watching the same section of the same movie sitting in the same spot talking into my work voicemail reading the same script while calling out the TV volume numbers.
Before root, I could go up to 20 before hearing muffled background noise (20 on my TV is unbearably loud, I usually watch TV around 13 or 14). After the root and RubiX Focused, I can clearly understand what is being said on the movie with the volume level at 12. Does anyone know anything about this? I'm wondering if the blur dialer app is what runs the mics and whatever that RubiX dialer is doesn't know to run them.. dunno. But it is very clearly not working now. Have you seen anything anywhere? Has anyone else tested before and after root? This is the key feature to the phone for me since I am constantly on the phone with clients.
