Android :: Contacts From 1.5 And 1.6 - Filtering Out Trash

Feb 24, 2010

I am trying to write a clean bit of code that can list the people in a 1.5/1.6 Contacts data store, and I do not see how I filter out the cruft that Google throws in (ad hoc "contacts" literally addressed by other apps and stored, for some reason, in the contact list without a clear means of discerning them from the real people the user cared to enter - the ones that would appear in the contacts app). I see that in 2.0 or so, "IN_VISIBLE_GROUP" is added as a field which seems to differentiate these versions, but what existed to accomplish this before that time? Here is my code which works in 2.x and fails to keep the chaff out in 1.x, as the selection parameter is unsupported:
final String[] proj = new String[] { Contacts.People._ID, Contacts.People.NAME };
final String selection = Build.VERSION.SDK_INT < 5 ? null : ContactsContract.Contacts.IN_VISIBLE_GROUP + "=1";
Cursor people = context.getContentResolver().query( Contacts.People.CONTENT_URI, proj, selection, null, Contacts.People.DEFAULT_SORT_ORDER);
if (people != null) { final int personIdColumn = people .getColumnIndexOrThrow(Contacts.People._ID);
final int nameColumn = people .getColumnIndexOrThrow(Contacts.People.NAME);
while (people.moveToNext()) { if (Thread.interrupted()) { people.close();
outputList.clear(); throw new InterruptedException();
} long personId = people.getLong(personIdColumn);
String name = people.getString(nameColumn);
if (name != null) { outputList.add(new Contact(personId, name));
} } // clean up cursor people.close();
}

Android :: Uninstalled Apps Leaving Trash Behind

Feb 9, 2010

i find it quite annoying that uninstalling an app doesn't remove all of its data.sure, this is desired behavior for some apps (a camera for instance), but imo google should have implemented a requirement for an app to explicitly request to be allowed to save permanent data, and if the request wasn't made, collect the location of any saved data and remove it upon uninstallation

Android :: K9 Mail - (IMAP) Trash Folder

Aug 30, 2010

When I delete a message from my K9 Mail app, it creates a label in my webmail account named "[imap]/trash". It also places a copy of the mesasge in the normal TRASH folder. I delete the [imap]/trash folder from my webmail account, but K9 re-creates it whenever I delete a message from the phone. How can I stop K9 from doing this, and only placing a copy in the normal TRASH folder?

Android :: Gmail Application Not Emptying Trash Folder?

May 14, 2010

Why will the gmail app not empty the trash folder? If I delete an email on the phone and then switch to the trash folder my emails are there. I then select them all again to delete as you would expect. Yet each time I reload the trash folder all the deleted emails are still there. If I want to really delete them I have to go in to gmail with my pc.

Android :: SMS App That Has Keyword Filtering?

Oct 31, 2009

I am looking for an all-in-one SMS app that can filter incoming messages based on words and phrases in the message. The reason being that I have monitoring systems at work that send SMS alerts and sometimes the alerts are just FYI, not OMG's

So anyways, right now I have a Hero, so I use Handcent for the replacement of the stock app until it is fixed and SMS Firewall to filter incoming messages and do the alerting. Being a 2 part solution it works very well, but I was curious if anyone has tried anything that has it all in one.

I have tried a few of the apps out there and none seem to work right.
Here's what I tried without success
aFirewall (didn't seem to filter properly)
SMS manager (can't remember what was wrong)
SMS Guard (kept getting a force close when a message came in)
PandaFirewall (didn't filter anything properly when I tested)
GSMS (force close when trying to view inbox)

I was going to try UltimateSMS, but it appears to have been removed from the Market.

Android :: ListView Not Updating After Filtering

Aug 5, 2010

I have a ListView (with setTextFilterEnabled(true)) and a custom adapter (extends ArrayAdapter) which I update from the main UI thread whenever a new item is added/inserted. Everything works fine at first--new items show up in the list immediately. However this stops the moment I try to filter the list.Filtering works, but I do it once and all of my succeeding attempts to modify the contents of the list (add, remove) don't display anymore. I used the Log to see if the adapter's list data gets updated properly, and it does, but it's no longer in sync with the ListView shown.

Android :: Filtering SimpleCursorAdapter ListView

Feb 27, 2010

Since the query that comprises my ListView basically gets the rowID, name, and a third column from my databases's table, I want to be able to filter the cursor based on the partial value of the name column. However, I am uncertain of whether I can do this directly from runQuery without expanding my DB class since I want to filter the existing cursor, or will I have to create a new query function in my DB class that partially searches my name column, and if so, how would I go about creating the query statement while using the CharSequence constraint argument in runQuery?I am also concerned about the performance issues associated with trying to run multiple queries based on partial text since the DB table in question has about 1300-1400 rows. In other words, would I run into a bottleneck trying to filter the cursor?

Android :: Anisotropic Filtering On Textures?

Aug 18, 2010

I'm just learning OpenGL ES on Android, and I am trying to get some kind of anisotropic filtering on textures. I want to increase the size of a sprite, with some kind of interpolation, instead of this "nearest-pixel-interpolation".

Is there anything like this in the OpenGL ES standard or do I have to make one texture for each size?

Android :: Filtering Sensors Noise?

May 21, 2010

I'm programming an Augmented Reality application. It's development it's in an advanced state but I can't place the icons on the screen so still as anothers programs does (Layar, in example). This is because of the continuous variations of the sensors. I've tried the three modes of the sensors (FAST, GAME, and NORMAL) but I only get them to move more or less fast. The shivering is the same at different speed.

Finally I thougth I could reach my goal with a digital filter, averaging historical values. But again the icons continues moving, specially the most far placed ones (in the z axis). Please, could some one help me with some clue?

Android :: Live Color Filtering App?

Nov 8, 2010

Anyone know of an app that can take video from the camera and display it live on the screen, but with color filters applied? Specifically, I'm looking for something that can amp up the color saturation. I've got lousy color vision and it'd be handy to have something to help distinguish subtle color variations. Nice-to-have would be an eyedropper mode that can tell me the rgb values of a selected region.

Dec 28, 2009

How can I get rid of all the Trash! I finally figured out how to delete emails from the inbox, but now they end up in the Trash instead! I have tried to read as much as I have time for regarding email. Perhaps I set it up incorrectly from the beginning. I use Outlook/Comcast and set it up in the "regular email" Perhaps I should delete that one and use Work email?

Android :: Market Filtering For Accelerometer Or Compass?

I just read the developer blog post about non-phone Android devices such as tablets and GoogleTV - http://android-developers.blogspot.com/2010/09/brace-for-future.html.

I'm writing an accelerometer-based game and would like to filter for devices that have an accelerometer (or orientation sensor). Is there a way to do that? It would also be useful to filter for devices with a compass or GPS receiver.

Android :: Filtering Dialog Items In OnPrepareDialog()

Aug 10, 2009

My application has a ListView displaying some items that are associated with different documents:

CODE:..........

The ListView implements an OnItemLongClickListener and displays the available document types as follows:

CODE:...............

I would like to modify onPrepareDialog to filter the dialog to display only the document types relevant for the long clicked item (like a context menu except that some long clicks will perform a different task: expand or collapse the hierarchy displayed in the custom ListView). For example, if an item is long clicked that is associated with only document types A and B, I would like the dialog to avoid displaying document types C and D as dialog items? However, looking at R.java, it is not clear to me what the id of an individual item in the select_doc_dialog_items array would be.

How to use onPrepareDialog() to filter displayed dialog items?

Android :: Filtering Accelerometer Data Noise

Oct 28, 2009

How do I filter noise of the accelerometer data in Android? I would like to create a high-pass filter for my sample data so that I could eliminate low frequency components and focus on the high frequency components. I have read that Kalman filter might be the best candidate for this, but how do I integrate or use this method in my application which will mostly written in Android Java? or can it be done in the first place? or through Android NDK? Is there by any chance that this can be done in real-time?

Samsung Galaxy S :: How To Get Rid Of Trash File On SD?

Oct 21, 2010

I've been trying to work out why I only have 5.9g of my sd card available when it says only 1.9g is used in my file browser (this is the 14gb internal sd card I'm talking about). Enabled show hidden files/folders and this .trash-1000 folder appeared with like 7gb in it. It's all the stuff I've deleted over time; movies, images etc.

All the stuff I delete I do via astro or when browsing the folder from my computer (ubuntu) so I'm wondering which created this file and how do I get rid of it. I can just delete the stuff in it, but I don't want to have to go through this time after time.
