i have a small issue i can't figure out.For my program, i basically want to execute some code if the user hasn't done anything with the application for 5 minutes (say log out).how can i go about doing this? i'm lost on detecting that the user has done nothing, and then reset the count once the user has touched the tablet or something. can somebody give me some pointers?

Is someone from Google able to advise when the Android SDK is likely to include a public API for reading/writing event data to the user's calendar? Searching the forums I see that this is a much desired feature by many developers but I haven't seen any indication as to when (or even if) this need will be addressed.

View 4 Replies View RelatedI have a facebook event in my device's calendar that is displaying the correct time on the main calendar, but showing the incorrect event time in two different calendar widgets I've tried, as well as the event list in the Facebook app.
To make matters more complicated, the facebook app is displaying a different incorrect time than the widgets.
I've removed the facebook event from my calendar, reinstalled the widgets, done a battery pull, resynced, and the problem persists.
I think the host changed the time of the event after I first synced it to my phone, but I'm not sure.

View 10 Replies View RelatedI am currently writing the backend for a service which has 3 clients: browser, android native and iphone native. I am having a little trouble with coming up with an authentication system since I don't know what can really be done on the clients.
I am using django + twisted for the backend.
Basically, I am going to be writing RestfulAPIs to open up for the clients on both phones to call.
Now the real question is, how should I come up with an authentication system?
I have thought about using sessionids, this works very well with the browser and I can use django's integrated app for that.
However, I don't know if it's possible for both the iphone and android to obtain a unique sessionid on the handset. Should I write an API call to distribute unique sessionids?
if that's the case, is it possible for me to still use django's authentication system since a lot of the stuff here are customized? ( I am not even using a rdbms - I am sticking with mongodb, so I was on the verge of dropping django's authentication app ftm).
I have looked at foursquare's API and their basic auth method requires you to pass in user:password in every http request header. That adds 1 additional authentication each call which can kind of seem excessive.
This is a pretty open ended question.I have a T-Mobile Touch and have some free time on my hands. So far as i understand im stuck with Android 1.5 and no sign of T-Mobile or Huawei releasing a ROM using a more up-to-date version of the Android SDK.Im asking what are the major complexities involved with making a ROM for this fone using a newer version of the Android SDK?

View 3 Replies View RelatedDoes anyone have any suggestions on where to start in case one wants to write a firewall for Android? I am interested especially in how would one go about in blocking access for various applications that are blacklisted from a firewall application. As far as I could find, there are no firewall applications in the real sense except Droidwall which uses iptables on rooted phones, but I would like to see if there are any API calls currently in Android that may help with this task, be it NDK or SDK.
View 3 Replies View RelatedI'm looking for a way to programmatically save an array of shorts as PCM data. I know that this should be possible, but I haven't found a very easy way to do this on Android.Essentially, I'm taking voltage data, and I want to save it in PCM format. My function looks something like this:public void audifySignal(short[] signal) {// Create a WAV file from the incoming signal}Any suggestions would be awesome, or even references. Seems like the audio APIs built in to android are more geared for directly recording from the mic, and not so much for lower level signal processing type work (at least for saving raw data to a file). I'd also like to avoid having to manually write the PCM file headers and what not.

I have a game object that I save like this in OnPause()try {final ObjectOutputStream os = new ObjectOutputStream(openFileOutput(gameName + ".sav", 0)); os.writeObject(gameObject); os.reset();} catch (final Exception e) {e.printStackTrace();This works fine except on some of the older or slower phones it can sometimes take too long to complete. I end up getting a ANR (Activity Not Responding) error. I would like to move this to a thread to prevent blocking the UI. However when I try this I run into multiple problems.First openFileOutput is only available in my activity. I worked around this by passing the ObjectOutputStream to the thread. After that I could save the object but later when I tried to reload I get a java.io.EOF Exeception. does anyone have a good pattern for writing objects to a file from a thread?

View 7 Replies View RelatedMy calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:
Unable to parse response from server
Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.
I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.

Before I invest too much time in this path, I'd like to know: Is this even possible? Some previous threads indicate Android won't do host USB. Would it require root access and/or the NDK? Would it be better to advise the potential client to look for a serial blue tooth adapter? I can see that there is a Blue tooth Sock class which may do the job.
