I would like to write an Android application that can be activated by sending it a command from a web site. Is this possible? Actually, the app would be running on the phone and I would be sending it a command via HTTP.

I am just wondering about how android handles sms when it receives them. More precisely my question is when the android phone receives a sms message, which application saves the message to the mmssms database? Is this done by the OS or by the native sms application?

Why does app not get onDestroy when exited but then receives an onCreate when relaunched?
Here is the trace. Launched app
It received onCreate and the other expected on calls for a launch. Now, leave application with the home button and it receives onSaveInstanceState onPause onStop
And returns to the main Android screen (the one with Google Search at the top) Launch the app again and it receives onCreate onStart onResume
The docs say onCreate is Called when the activity is first created. But here it is never destroyed but created again. There are many objects that never got GCed because the app was not onDestroyed?
Is this a memory leak? What have I missed? Or should I assume that onCreate can be recalled for an already created app.
I can send MMS messages perfectly fine, but if someone tries to send me one I get nothing. No notification or any way of knowing I didn't get it unless someone tells me they tried to send me one.
I see in the GO SMS settings the MMS part is in Red, but there don't appear to be any settings to resolve the issue.

I have a rooted samsung captivate with sideloading enabled. After experimenting with different wifi tethering apps from the unofficial market, I began experiencing difficulties with my wifi connection. Even after uninstalling every app that I thought was changing the wifi state, the problem still persists. I can turn on the wifi and it will act normally for about 30 seconds before turning off without user intervention. In dmesg, the error is as follows: 'mmc1: Got command interrupt 0x00060001 even though no command operation was in progress.' Is this caused by an app or is this a more complicated problem?

It is as if the phone is preparing to make a call. Anyone have any ideas what is going on here? (of course, I'm only looking at the phone while stopped at a traffic light.)
View 2 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.
When implementing download function it work but during file saving to sdcard i get the following Default buffer size used in BufferedInputStream constructor. It would be better to be explicit if an 8k buffer is required.Also IO Exception occure

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?

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.
