I've looked at getRelativeTimeSpanString() but 1) it calculates from now & 2) it appends a prefix/suffix.
Is there an easier way to do this, other than creating a custom datediff method and chopping all of that together with conditions myself?
I'm experienced with php, javascript and a lot of other scripting languages, but I don't have a lot of experience with java or android. I'm looking for a way to send POST data to a PHP script and display the result.

I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value).
There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code...
I need help in setting up value and display text in spinner. As per now I am populating my spinner by array adapter e.g. mySpinner.setAdapter(myAdapter);
And as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. Now in my case I want to make spinner like the drop down box, which we have in .NET. Which holds a text and value. Where as text is displayed and value is at back end. So if I change drop down box , I can either use its selected text or value. But its not happening in android spinner case.
For Example:
Text Value
Cat 10
Mountain 5
Stone 9
Fish 14
River 13
Loin 17
So from above array I am only displaying non-living objects text, and what I want is that when user select them I get there value i.e. like when Mountain selected I get 5. I hope this example made my question a bit more clear.
I want to ask where does the defaults values of memory min-free values of a Rom reside? I mean what file I would have to edit to edit those values?

We can convert from Intent to URI and from URI to Intent. From Intent to URI string Intent intent1 = new Intent ();
String uriString = intent1.toURI ();
From URI string to Intent Uri uri = Uri.parse (uriString);
Intent intent2 = new Intent ();
intent2.setData (uri)
After conversion, intent1 and inten2 should be same. for example:
Intent intent1 = new Intent ();
intent1.addCategory (Intent.CATEGORY_HOME);
intent1.addCategory (Intent.CATEGORY_LAUNCHER);
Log.v ("", "Intent1 = " + intent1);
if (intent1.hasCategory (Intent.CATEGORY_HOME))
Log.v ("Intent1", "#1 hasCategory TRUE");
else Log.v ("Intent1", "#1 hasCategory FALSE");
String str = intent1.toURI ();
Uri uri = Uri.parse (str);
Intent intent2 = new Intent ();
intent2.setData (uri);
Log.v ("", "Intent2 = " + intent2);
if (intent2.hasCategory (Intent.CATEGORY_HOME))
Log.v ("Intent2", "#2 hasCategory TRUE");
else Log.v ("Intent2", "#2 hasCategory FALSE");
result Intent1 = { categories=android.intent.category.HOME,android.intent.category.LAUNCHER} } #1 hasCategory TRUE
Intent2 {data=#Intent;
category=android.intent.category.HOME;
category=android.intent.category.LAUNCHER;
end } #2 hasCategory FALSE
In this sample code, Intent2 is a conversion result from Intent1. If you run this sample code, Intent1 result and Intent2 result are different. Because Intent1 and Intent2 have a same Intent.CATEGORY_HOEM, the result should be Intent1 and Intent2 is TRUE (intent.hasCategory). I think this is bug. And the hint is Intent1 and Intent2 's toString result is different.
Intent1 = {categories=android.intent.category.HOME,android.intent.category.LAUNCHER}
Intent2 = { data=#Intent;category=android.intent.category.HOME
category= android.intent.category.LAUNCHER;end }
I don't know how to convert Intent to URI(String) and convert URI (String) to Intent. I want to save Intent to DB and read Intent from DB.
My application that uses geocoding was working fine till last week and now all of a sudden am not getting proper data from the same.
I used getLocality() , which was returning CITY name previously. But now it is returning NULL.
Is something changed? or Has someone faced the same issue?
My application is on SDK 1.0
According to my research, which includes reputable sources (Mark Murphy et al), the most preferred way of polling a remote source and presenting said data to the user is by creating a service and using AsyncTask within that service to do the polling. I have done that.But, when I read the docs there seem to be several "Threading Rules" that conflict with this way of doing things: "The task instance must be created on the UI thread." and "execute(Params...) must be invoked on the UI thread." As stated, I have created the task instance on the Service thread (not the UI thread). Am I missing something? Also, when the AsyncTask finished, I sent out a Broadcast on onPostExecute, which is then picked up by the Activity, telling it to retrieve the final value again from the service (since I couldn't obviously update the UI from the service). I couldn't figure out any other way to return the result of the AsyncTask. Is this the correct practice?

View 3 Replies View RelatedI meet an issue: my activity cannot return result.
I created an activity which has one TabHost. I added three tabs using mTabHost.addTab. Every tab will launch an activity(activity A, activity B, activity C). In activity A, it will call startActivityForResult to start activity A1. The issue is activity A cannot get any result after A1 finish.
What is the reason? How should I do if I want to get return value?
I'm doing some network job in AsyncTask. Sometimes it requires communication with user. (connection is dropped, session is expired and so on). I want to pop up a dialog or launch an Activity, and then, depending on user's input, stop the job or redo it. I can launch any Activity from AsyncTask, but how to get result back? It seems to be possible only if I launch new Activity from another Activity. What are possible solutions?

I have a Service which needs to receive data from external packages. So, to locate the data providing external packages, I use activity- filter and PackageManager.queryIntentActivities function to locate the interesting packages. Now, from each such package, I need to get a ContentProvider URI. So I want to start the external Activity and the external activity will return a result to my service - something like "startActivityForResult". The problem is that there is no way to call "startActivityForResult" from a Service, only Activity can do that, and my project does not have any Activity, and probably can't show UI for the user.
The bottom line: Can anyone suggest a way to get ContentProvider URI from an external package, while my package has only a Service?

View 5 Replies View RelatedI have SQLITE DB query which returns me one record at a time.
This is the query :-
rawQuery("SELECT id, category_id, title, text FROM customer WHERE (reads = (SELECT MIN(minReads) FROM categories)) AND status = 'a' ORDER BY rating DESC, rand_index DESC LIMIT 1 ",null);
If I want to fetch next record as we are applying limit in my sqlite query above i m unable to get next record. Limit 1 is necessary as i have thousands of record in my db.
How can I fetch next record without modifying the existing query. I cannot apply loop on this as I have lots of records and I don't want all the record at the same time. I want it to be fetched dynamically one by one. I want to be be something like where I can store result in an array as I might need old record as well while getting next record.
I hope the title says it all: I've got Activity A which fires up the Camera intent via:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
After the picture is taken I can easily grab the picture in:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
But I'd like to receive the result in Activity B in which the image can be edited.
Right now I'm receiving the result in Activity A and pass it over to Activity B which results in showing the GUI of Activity A for a short while:
Intent i = new Intent().setAction("DisplayJPEG");
i.setClass(this, EditImageActivity.class);
i.putExtra("IMAGE_URI", uri);
startActivityForResult(i, REQUEST_EDIT_IMAGE);
Of course, I will need the result from Activity B in Activity A after the image has been edited. But that should work with:
setResult(resultCode, data);
So there has to be a way to do what I need. Please point me into the right direction.
I just want the device to function again no matter what way. (Don't care if it's factory reset completely it has nothing on it I was just using it for a bit of experimenting).
So anyway, I have an HTC One x that I tried to install Cyanogenmod mod on but when trying to flash it (I was a bit impatient and just did what I thought would work), it didn't work and I'm stuck on the HTC Boot screen. I can still restart the phone and get to the recovery menus or whatever they're called. But even when doing a factory reset it still just won't get past the boot screen.
I thought I might experiment with rooting and all that, (I don't want to do this to my main driver, the Z1, for the life of me).
I was trying to use some of the new camera methods included in Froyo, i.e. setPreviewCallbackWithBuffer() & addCallbackBuffer(). In the documentation it's said you need first to create a buffer of appropriated size and use the addCallbackBuffer() method. The buffer size must be width * height * bits_per_pixel or otherwise you'll never receive a preview frame. To know the image size, you can ask to the camera about it's configuration. When I'm trying to configured the camera I use Camera.getParameters().getPreviewSize() the emulator says the size is 320*240, but with that size it didn't work on emulator. I used the old setPreviewCallback() and, in the onPreviewFrame(), I asked the size again. That time the size was 480*320. Then I hard- coded that values in the first code and everything worked. Now I'm afraid not only the emulator would have that behavior. Unfortunately I don't have any real device with Froyo and I can't try it. So, anyone have tried that methods in real devices? btw, are they really increasing the poor performance and frame rate?
