One of the winners of the Google app contest was Jigsaw by Mikhail Ksenzov, an app to capture and process whiteboard data. The app isn't in the market, and I can't find anything via Google about it's status. Is it still beta, or what?

I am working on a packet switched network. I want to capture the audio data from mic into a buffer at a desired sample rate.How can I capture the audio data from mic into a buffer instead of a file? Also how can I control the audio capture rate as per the desired sample rate?

View 3 Replies View RelatedI am a developer with an existing android app. Users have asked for a wifi only mode to avoid roaming charges when traveling. I believe I have set it all up successfully but want to be able to validate that theory..
What I am trying to figure out is if there is an app or other way to trap the data coming out of the app via the cell network (lots of background web service calls). Since I do not own all of the web services, I cannot trap from the server side.
I basically want to turn on a trace like you would do in SQL, and look at what is being transmitted on the phone when wifi is off but cell is on. I don't need the actual packets, just that a call was made to one of my https services. If a call is made in wifi only mode, then I know I didn't get everything.
I overheard someone say there was an app that blanked or put a decoy screen on the screen while taking video, does anyone know what this app is called, if it exists?

View 1 Replies View RelatedIs there an app that I could install on my Samsung Galaxy Tab 10.1 that would turn it into a Whiteboard that I could control from my Galaxy S4 or my home desktop PC?
I'd like this to put in my mother-in-law's room. At the moment, I'm using an actual whiteboard, where I maintain the Day and Date, any appointments coming up (she thinks she has one every day; in reality, it's one a month at most). Most importantly, it has the location of my wife (and me) and our phone numbers (m-i-l can drive a "steam" phone, but mobiles/smartphones are beyond her).
There are also answers to key questions, which come up about 40 times a day:
Q: Did you have a dog as a child. A: No, I was allergic to dogs. Q: Was the bombing bad where you lived during WWII? A: No, I was still a sperm/ovum trying to meet, during WWII.
Keeping this up to date is a task that the tablet could do almost by itself, once I'd told it to display the Day and Date, and pertinent facts.
If there's nothing off the shelf, what are appropriate means of tempting a developer to build a bespoke app? I used to be a website author before I retired, and I could almost do this in a day, by setting a browser on the tablet to repeatedly fetch a webpage from the Apache server on my desktop PC ([URL]... but don't get excited; it's the dullest page on the web). However, I'd like the tablet display to be utterly void of any controls, because m-i-l is an inveterate finger-poker. She's probably avoid the buttons on the tablet (they're hard to find in the leather case that holds mine)
If I get all of this working, then I'll need the strangest Galaxy Tab 10.1 accessory: A flashing neon sign, saying "Read this" with an arrow pointing to the display...
I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

I needed to call a remote service. The service basically fetches data from the network. I am bind the connection once,and then I unbind the connection when the user is no more in that page. Everything works fine.Except that when I call the sa,e remote method for 17th time,it just does not call the service at all.It neither throws the DeadObjecti Exception. I have run out of ideas.Is there anything that I may be missing.
View 7 Replies View RelatedIf an application begins a Service via bindService or startService, will this Service object ever run from a process different from that of the application? I ask because many Android example projects begin a service and communicate to them using IPC which seems wholly unnecessary considering that, according to the Android Service documentation, "... services, like other application objects, run in the main thread of their hosting process." IPC, AIDL, and the IBinder interface only seem useful if connecting to a Service started by an application other than your own. Is this a correct or fair understanding?
View 1 Replies View RelatedMy app is made of two activities, A and B. I'm considering this sequence of steps: Activity A is started. A launches B [A is paused, B is running]. B launches a map intent [A and B are both paused now]. Now the user is using the maps application and the system decides it needs more memory. Can the system kill only one of my activities for memory, or will it always kill all activities in a "process" in this situation?
Both activities share some static data like:
class Data {
public static String mName;
public void save() {
// write to file: mName;...................
As an exercise I attempted to add an AppWidgetProvider-derived class to one of our existing Android applications. When the widget is created and appears on the home screen, the output from adb logcat notes: W/ActivityManager(58): Unable to launch app com.mycompany.myapp/ 10042 for broadcast Intent { action=android.appwidget.action.APPWIDGET_ENABLED comp= {com.mycompany.myapp/com.mycompany.myapp.MyAppWidgetProvider} }: process is bad
This output comes from around line 10814 in ActivityManagerService (looking at cupcake on git). This is running on an ADP 1.5, FWIW. The same AppWidget code, once separated from the main application's project and put into its own simple project, runs as expected, so I know my manifest entries/XML/Java are all as they should be. Has anyone else run into this, or perhaps can the Android team comment on what aspect of my application might be preventing the AM from starting up the process when the widget is added to the home screen?
For some reason I can't explain, when my app runs, I will on occasion get the following error message: "The application xxxxxxxx (process xxxxxx) has stopped unexpectedly. Please try again". When I debug my code, it seems to break at random places that doesn't make sense. On top of that I tried to surround the entire code with a try/catch block just to try to catch the exception, but it doesn't work either. I'm suspecting it's the OS that is producing this error message but I don't know why. As far as my code goes, if there were exceptions caused by it, it would've been caught by the try/catch block. Can someone shed some light here?
View 13 Replies View RelatedI am seeing a curious behaviour in my app. I have a widget that gets updated by a service every # hours, when the service finishes I stop it, using "stopService(new Intent(this, MyService.class));", the widget if pressed launches an Activity. Now it gets interesting, while im on the activity everyting works fine, then when I exit the app(by the back key or a button I designed which simply calls this.finish() ) the ActivityManager would tell me that my process has died, I do not see any error of any kind, just that the process has died.
Why I am seeing that message and what does it mean exactly? That is having a side effect on my service regarding static variables getting set to default. Could my code be the cause of this? Is there any way to know that your process has died? I have tested my app on a HTC Hero running 1.5, it always works well on the emulator and I never get that message. I know android kills processes to reclaim memory but Im always careful to close apps heavy on resources.
Is android's memory 16MB limit per Process or Application? If the limit is by process, I can make some services remote. That means the service will be in different processes, and the limit will be 16 x N.
View 3 Replies View RelatedBeing interested in Android development and still in the experimentation phase - there's something I haven't been able to grasp. As far as I've been able to understand, the process lifecycle and application lifecycles are separate and as such, it would be possible for the application to still to exist, even if it's process has been killed. So I guess my question would be, in what scenario could this occur and how is the application accessible if the containing process has been killed?
View 5 Replies View RelatedIn a comment on an epic StackOverflow question-and-answer, a gentleman who I will call Tim has outlined a scenario he says he is running into, one I have some difficulty believing. Reading somewhat between the lines, the flow would appear to be this:
1. User taps on an activity icon in the launcher 2. Process starts up 3. Application object is put in that process -- and a custom Application object loads an NDK library which initializes some statics/singletons 4. User uses application 5. User abandons application (e.g., HOME) 6. Later, user returns to application, before the first process is killed or recycled for use with another app 7. A second Application object is created, in the same process, before the first Application object is called with onTerminate()
This screws things up for Tim's app -- apparently, it does not deal with pre-initialized statics/singletons well. They were presumably counting on onTerminate() to let them clean up the NDK space. As a result, they are relying upon killProcess() (somehow...unclear under what conditions they might call this) to force their own process to go away, so their statics get cleaned up. Step #7 is what confuses me. I can see a new Application object being created, but only if the first Application object were terminated. I don't see any NDK-related bugs out on b.android.com that seem to match this complaint, though in principle it might cause problems for non-NDK apps as well. Has anyone encountered a new Application object being created in a process before the old one is terminated?
I was working on implementing a more advanced list view then the standard one they teach you in basic tutorials, and I did find a great tutorial explaining how to create your own Adapter and such not. http://www.softwarepassion.com/android-series-custom-listview-items-a...
I do have a working version of the tutorial and I am currently in the process of changing the list to suit my needs, but there are a few issues I am stumped on. If your run the tutorial code it creates a little progress dialog saying that it is retrieving data. In my application it is going to be fetching data from the internet and storing it in an ArrayList of custom objects. However if I where to rotate the screen the progress dialog pops up again, I have no clue on how to set it up so that when it rotates that it doesn't recreate everything and re-fetch the data and process it again.

Camera application process dies and restarts again when device is Locked/End Call Key is clicked. Steps to reproduce: 1) Launch Camera application. 2) Click on End Call key(it acts as lock screen when there is no active call) or wait till device is locked. 3) Camera application is paused and surfaceDestroyed callback is not being called. 4) Camera process has died and restarted again. I would like to know why Camera process has died after onPause is being called and restarted again when device is put to Lock state. For all key events like BackKey,HomeKey and Accept Key it is working fine.
