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.

I'm writing an app that will periodically send information out to a remote server, and then get relevant information about other users from that server back to the local database.What's the best way to handle sending out this info (i.e.: XML or binary) and writing it to the remote server.Also,how can I assure that, when 500+ users' data get's to the server or FTP (or better alternative?) at once, the appropriate fields gets overwritten or added, without skipping any or overwriting the entire thing?
View 1 Replies View RelatedI've been looking around on the net and in this group, but i have not found any java package that can read and write EXIF data.
I tried Sanselan. They say they don't use ImageIO/AWT, but they actually do use AWT. The class can not be loaded because there is an AWT dependency:

What i want is not so much creating my own EXIF data, but preserving a JPEG's meta-data (EXIF). I'm planning to load a JPEG, edit its bitmap and write it out again to a(nother) JPEG with the same meta-data as its original.
I'm trying to read from a file while it still opened for witing.
View 2 Replies View RelatedI've had an inquiry about whether my Android app can interface with a serial device via USB cable. 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.
View 4 Replies View RelatedI'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?
Android does not provide an Exif Reader or Exif Writer in its SDK (it has a native implemenation, though, but that API is private).
The Sanselan library, however, does provide a full fledged set of functionality for reading and writing Exif metadata.
However, Sanselan pur sang cannot be included in an Android Project. It references classes and packages that do not exist under the current version of Android (e.g. ImageIO).
Therefore, I made a quick cut of Sanselan 0.97, cutting out all the classes that prevent it from being used on the Android platform. It is a quick cut and it may have some issues. However, I got its exif reading and writing to work for my application and it looks like its working quite well. Reading and writing raw image-data is, however, not possible in this cut. This has been cut out.
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?

Have successfully imported my old calendar to Google Calendar which initially synced with the calendar on my captivate. However, when I add a new event to my phone calendar, it does not automatically show up on the Google calendar. the Samsung rep told me I have to edit each new even to mark it as a "Google Calendar". Is there any way to make this the default option on the Captivate phone? I am hoping to have automatic syncronization b/t the phone and the Google calendar without having to force it to do so each time.

I think I've seen somewhere that it's still not possible to read Google Calendar entries? I tried to search the forum, but didn't find any relevant threads. They mostly contain questions on java.util.Calendar.
Can I read entries? I understand that it might be fragile if it still isn't in the public API, but I don't mind updating my code when the API becomes public. (I don't need to modify or create new entries).
I'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 kept getting annoyed at having to load the Calendar to have to add an event, so I built a one-tap-add-event app which you can put on the home screen.
View 2 Replies View Relatedall in my application I want to read data from web page. if data at web page is upto 800kb then I am able to read it succesfully, but if data is larger then I get OutofMemoryException.I think it is because I am using condition as while ((inputLine = in.readLine()) != null) and in phone there is not much memory to read such a long string. I think I must have to read some part of string then write that part into some file in phone and read another part of string and write into phone but I don't know how to do that? Please help me solve this issue.

View 1 Replies View RelatedI need to explore the world "You wrote a killer application, but do you have an Android/iPhone/iPad client?".
My questions are:
1) which is the best way to send data to those devices? Soap and Rest as suggested here? Or are there some specific techniques? (My app is written in Delphi and I can expose data with webservices if needed)
2) For x-platform (where by x I mean basically apple products and android) development is there a tool? Or the only solution is write one client per platform that "embeds" a web application optimized for mobile devices?
3) which are the techniques for caching locally some data / working offline? Is it different in the 2 worlds or is it common?
I am developing an application that read data from sensors and write those data to an XML file when you press a key. i have 2 activity one for button and another is an Activity who implements sensorEventListener. the problem is my main activity is button and couldn't get data from event listener activity. i think the listener activity is not active but when i create an intent and start activity with that intent the program stop working. the button is able to create XML file solely.so how could i read sensor data from sensors,and how to send them to XML file when the button got clicks.

Similar to how blackberry's handle calendar events..
After buying my lovely HTC Desire two weeks ago I'm now trying to start using my phone as an organizer/agenda.
Unfortunatly I really have sucky memory (hence I need to use the agenda from my phone) and thus I actually have NO idea what date it is today and everytime I goto the add event dialog I forget to look at the calendar what day it curently is (let alone tomorrow!).
Since the default app only has those anoying slider/slotbars to pick the date for an event... I keep placing events on the wrong date! :@
I've been trying to find a replacement app but the only two I've found so far (Jorte and Gemini) have the same anoying dialog to add an event!
All the other 'apps' I find when looking for android calendar apps are widget-only!!
Anyone knows a way to get a datepicker or something like that into the calendar app or a different app?
Maybe at least display the name of the day when creating a new event?
My app wants to whisk the user to the "create new event" composition window of his Calendar app, initializing begin time, end time, title and description text for the event, but then leaving him able to see these values and optionally alter them before saving (or discarding) the event using the oridinary means available to him from within the Calendar's create new event activity.
HOWEVER...
My code which works dandy on my own dev phone (indeed, on any phone running stock Android Calendar to the bone) fails on the HTC Hero. The issue is that the Hero has been "improved" by use of a non- standard Calendar app and my means of doing this is therefore failing.
I wonder if someone can outline a more generic means I can use to say "tell whatever the user's preferred Calendar app is to create a new event, seeding the effort with these key/value pairs".
Here is my present code:

I use Google Apps, and use several separate calendars. Problem is, if I don't create my event on the right calendar in the first place, I can't figure out how to move it later to the correct calendar.
I can do it in the web interface, just not in the Calendar app.
