Pretty new to Android development here.Is there an example out there of a working app with source that does something when you shake the phone? Is this doable in a background app? Done quite a bit of googling and can't find any good examples; only tutorials with little context.

Can any one help with how to test sensor events like shake on Android Emulator.I have found some posts pointing to openintents but can anyone explain how to use it in android 2.0 avd.
View 1 Replies View RelatedI have a class A which extends TabActivity and creates Activities B, C and D as tabs in its onCreate() function. Also, class A initializes another service handler class S which is responsible for establishing a connection to a service and implementing callback handlers for the service. Any of the Activities B, C and D should be able to receive events from the service and update accordingly. If I receive any event in class S from the the service then I want to call a function in Activity B which would be responsible to update the UI elements in Activity B based on the event received. You can assume that the user is in Activity B when the event arrives.
Can I call an activity function like the following in the stub handler for the callback in my class S -

The things that sometimes a brute force shake would be most helpful for and that I would pay money to have my phone do:
1. Shake to full brightness. When it's too bright to see the screen, it's a PITA to try to get the brightness turned up.
2. Shake to current phone call. Occasionally, I exit the phone app and it's frustrating not to be able to hop back over there quickly.
3. Shake to unlock. It's annoying to always be swiping when I just want to quickly check something on my phone. A quick shake would be much easier as an option.
Is there any Listener able to listen for shake movement. when someone shakes the phone an event should be triggered ,how I'm supposed to do that ,any idea on this topic is appreciable.
View 12 Replies View RelatedI've been playing with the data given by the accelerometer,trying to work out how I can gauge a shake from front to back or side to side. This all seems straightforward enough.But I'd love to know the direction of the shake. So, if the user is shaking backwards and forwards, I want to know if the device is moving away from the user, or back towards him/her. I can't find any way of telling this.

View 1 Replies View RelatedI need to add a shake feature that will refresh my Anroid application.All I find of documentation involves implementing the SensorListener, but Eclipse tells me it's deprecated and suggest SensorEventListener. Anybody that has a nice guide to how I go about creating this "shake controller"?
View 5 Replies View RelatedI would like to detect shake movement in a service that is running in the background, even when the phone is not currently being used. Is it true that the only way to do this is to hold a wake lock? I suppose this would consume a lot of energy and drain the battery very fast.Is there no way to wake up the phone whenever a shake movement occurs? Maybe with the native sdk? I would imagine the accelerometer causing some kind of interrupt.

View 1 Replies View RelatedHas anyone implemented an Android Shake Detector that works well on most phones?I thought it would be fairly simple to implement but I keep getting false results. Basically, what I'm doing is setting up a sensor Listener, checking to make sure it is a SensorManager.SENSOR_ACCELEROMETER event, then only checking the event if the last event I received was more than 50 milliseconds ago (to try to reduce the amount of checking I do).Then I look for 3 "Shakes" within 4 seconds.A "Shake" to me being a speed reading of over 1000 followed by a speed reading of less than 400 within 1 second. If I don't get three "Shakes" within 4 seconds then the counter is reset to zero.At times it seems to work well but I continue to have instances where I just pick up the phone, and it triggers all three shakes, which makes very little sense to me because at other times, I can physically shake the phone quite hard, and not trigger all three shakes.As I said.. it works about 90% of the time correctly, but a 10% error rate is making the feature I want to implement useless.

View 3 Replies View Relatedim privileged to be one of the few people in my circle of friends that own a droid and i blow them away in many feature comparisons as they all have iphones or blackberries but i noticed through the apple app store there were many cool apps where you can just shake the phone for certain features like wake-ups notifications and even being used in popular games just wondering what Android has that has that kinda cool "shake" feature i think it would be sweet.

View 1 Replies View RelatedI read somewhere not to exception handle when developing in Android, is that true?
If one does need to exception handle are there any logging tools for 2.1 and above?
If shouldn't exception handle, why is it not recommended to at least use the below?
try {body-code} catch (exception-classname variable-name) {handler-code}
I'm using a PostMethod, and wondering what try/except handling I should use.
The exception handling here seems to work okay in most scenarios, but is there anything I might be missing? In particular, I'm wondering whether this handles the network connection going down midway through the upload.

View 2 Replies View RelatedFrom the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest:
Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.
Why does it say this?
In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity.
While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself.
Why should it be avoided?
I guess I should also ask: would this be an acceptable reason for doing the orientation configuration changes yourself?
I'm trying to do is draw circles around two points that are being touched, and as the fingers drag along on the screen, have these circles follow each finger.
However, I'm getting some weird behavior that I can't figure out. So when I place two fingers on the screen I get my circles no problem. When I drag around with the two fingers everything works like I want it. However, if I lift the first finger, everything stops redrawing, and the second finger that is still on the screen stops being tracked. If I place the first finger back on, everything behaves good again. I figure I must be handling the two fingers poorly.
Also, if I have two fingers on the screen, and I lift and touch the second finger, everything behaves well. It's only in the case where I have two fingers and I lift the first one do I see a problem.

I'm developing an app and i need to detect when the user shakes the phone from side to side , that means just along one axis (in this case X).I want to know when the user shakes the phone to the left and when to the right, the problem is that my code does not detect shaking but tilt, i have tested this code and it works when i tilt the phone to left or to the right, but not when a shake it from side to side (no matter the orientation of the phone).
View 2 Replies View RelatedI know how to use handlers to update UI elements such as progress bars toasts etc. The problem I am having is when the context goes away such as the user pressing the back button or the Activity finishing for some reason. This causes my application to crash often. I tried using
getApplicationContext()
(Thinking that this would be available throughout my entire application) but this did not work, ever - instead my application crashed! I put try catch blocks around all UI update code, this works but is it necessary? What is the bast way to handle this?
I have some required try/catch statements in my application that in my testing never get called. I have sent them up with:
Log.e("messaage", e.toString());
For my debugging and now that I'm ready to release I am not sure if I should take that out or not. I see in android market you can get error/crash reports and while I do not expect my app to catch any errors, I would like to know if that happens and wondering if I need specific syntax for that. My question is what should I do in the catch statement for these errors? I'm already handling the error from a user standpoint...
I want to handle key press and long key press for the key code KEYCODE_CALL(dial button). can any one suggest me how this in android 1.5(API level 3).
