Is there a way to convert JSON Array to normal Java Array for android ListView data binding?
View 2 Replies View RelatedI have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);
where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);
The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?
I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?
View 3 Replies View RelatedI'm parsing a very simple XML schema with a SAX parser in Android. An example file would be
<Lists>
<List name="foo">
<Note title="note 1" .../>
<Note title="note 2" .../>
</List>
<List name="bar">
<Note title="note 3" .../>
</List>
</Lists> the represents more note data as attributes that aren't important to question.I use a SAX parser to parse the document and only implement the startElement and 'endElement' methods of the HandlerBase to handle Note and List nodes.However, In some cases the files can be very large and take some time to process. I'd like to be able to abort the parsing process at any time (i.e. user presses cancel button).The best way I've come up with is to throw an exception from my startElement method when certain conditions are met (i.e. boolean stopParsing is true).Is there a better way to do this?I've always used DOM style parsers, so I don't fully understand the SAX parser.One final note, I'm running this on Android, so I will have the Parser running on a worker thread to keep the UI responsive. If you know how I can kill the thread safely while the parser is running that would answer my question as well.
I have an instrumentation test case that is waiting for an incoming call. I would like to abort this test case after some time from outside of this test case. Is there any argument to "adb shell am instrument" command that will stop the on going instrument test case?
View 2 Replies View RelatedI'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.
Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);
That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.
Is there a simple way to convert a JsonArray to a standard Java Array? Obviously, you can iterate and do it explicitly, but I wanted to see if there was a direct way to do so.

View 3 Replies View RelatedI am using a DefaultHttpClient and a ThreadSafeClientConnManager to share the httpClient across threads. That part is working well. However, when I execute an HttpPost in one thread, and call httpPost.abort() from another. It does not return immediately and continues blocking until the socket timeout is reached in most cases. Am I missing something else? I've tried using: connectionManager.closeIdleConnections(30, TimeUnit.SECONDS); connectionManager.closeExpiredConnections();
View 2 Replies View RelatedI'm having problems during the "read" call of the InputStream. The call gives me a "IOException: Software Caused Abort" exception. I'm able to get the BluetoothSocket and also the able to "connect" to the device. My app. is in the client mode and sends in a "x" byte "command" to the device which is then supposed to send me a "response". The expected "response" is also of "x" bytes. This is where the error arises.. While reading the "response" i'm getting the above mentioned error.
View 5 Replies View RelatedI'm using ThreadSafeClientConnManager to manage a pool of client connections, because my application has several threads, which are simultaneously connecting to a webserver.
Abstract sample code:
CODE:..............
Now lets say on of this threads is downloading a large file, but then the user of my application is switching to another activity/screen. Therefor the file is needless and I'd like to abort this download connection.
In ThreadSafeClientConnManager I found this method: public ClientConnectionRequest requestConnection (HttpRoute route, Object state) Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the request can be aborted.
So far I've been using:
CODE:.........
Now from what I understand, I've to use:
httpclient.getConnectionManager().requestConnection(HttpRoute route, Object state);
And that's the point where I'm stuck. I assume that for the route I can just use new HttpRoute(new HttpHost("10.0.0.1")) or whatever my server is, but what to put in for Object state?
And second, as soon as I've the ClientConnectionManager I can call getConnection(long timeout, TimeUnit tunit). But then from there, how I do I execute my HttpGet httpRequest = new HttpGet(URL_TO_FILE); as I did before with HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);?
I've been gone through the documentation and tried out quite a few different things, but I wasn't able to obtain a working solution. Therefor any suggestions and/or code examples are more than welcome.
I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?
View 3 Replies View RelatedI was very confused when I looked at the list of my contacts the first ftime after syncing them to the Desire. Only then I realized: this thing is sorting first names first! I find this most annoying and unusual. And worse: I found no setting, yet, that would allow me to choose the sorting.

I'm writing a microblog client for Android to go along with my Windows client (MahTweets). At the moment I've got Tweets coming and going without fail, the problem is with the UI.
The initial call will order items correctly (as in highest to lowest)

After the tweets are processed, I'm calling adapter.notifyDataSetChanged();
Initially I thought that getItem() on the Adapter needed to be sorted (and the code below is what I ended up with), but I'm still not having any luck.

Is there a better way to go about sorting ListViews in Android, while still being able to use the LayoutInflater? (rowLayout = t.GetParent().GetUI(t, parent, c) expands the UI to the specific view which the microblog implementation can provide)
I want to create multiple handlers that gets triggered based on users selection, but this handlers implement the same runnable method. the only difference is that they call different postDelayed() method. how do i go about achieving this without rewriting the same code for the runnable? i am still not clear about how the handleMessages() works and if it can be used for this?

View 1 Replies View RelatedDoes anyone else wish that the Android Market had sort options? I know when I browse the Market, I can filter by paid apps vs free apps. That's part-way there... I also want to be able to sort by rating/ranking (# of stars), number of times downloaded, cost, and so on. Also, carry these sort options over to the Search. It's even worse as you have paid and free apps mixed together.
View 2 Replies View RelatedI am sorting my database depending on date. The date field in SQLite is nothing but a string, stored in the form of dd-mm-yyyy. How do i carry out the sorting.
My idea is to create a dummy table.Convert the date in a format yyyymmdd. Then sort it simply using sort by date column.Then again drop the table.
I'm looking for a detailed App for sorting and categorizing all of my contacts. I have 700 phone numbers, and am a junior in college, so needless to say, sometimes it's nice to only see female phone numbers. Also, if there is one where you could sort people by key words like soccer, school, parties, etc. Also, with the Verizon network, is there anyway to send texts to more than ten people at once? Is there anything like that out there available for my droid? Is there a way to sort/edit my contacts on my computer? I feel like it would be much easier.

View 12 Replies View RelatedOne of the task of we are working on is to enable the Android Contact sorting by stroke for LOCALE zh_TW. It's very easy to enable the contact sorting by Pinyin for zh_CN, but when I take the same method to enable sorting stroke for zh_TW, the sorting result is either sorted by UNICODDE or PinYin. It's very strange. I have investigated the related code located in android_pkgs/external/icu4c/xxx and tried many options but failed to find a wayout. Is there anybody familiar with icu4c or have ever done some work on this topic? Here I'd like to append the steps (mainly on the location android_pkgs/external/icu4c/) I did as reference:
a. append zh_TW into product locales;
b. append the zh_TW support into icu4c/stubdata/Android.mk
c. taking the cfg-us as example, create a folder cfg-us-zh and append zh_xx related 'zh_xxx.res' files;
d. ./helper.sh us-zh will generate a updated icudt38l-us-zh.dat;
e. recompile Android to launch emulator -EOM-
I implement ProviderTestCase2 to test my content provider functions. And when I insert huge number (about 10000) of data, the insert, delete and update functions are fine. But the query function will have SQLiteDiskIOOException: disk I/O error. And the data number limit of causing the exception is about 5000. Is it bug of content provider?
And there is another problem. Each of my data has different priority. When I sort my data by priority, its no problem. But when I change priority of some data and then sorting again. Sometimes I will get incorrect result and I'm sure its not logical problem of test program.
Is it possible to actually re-sort an Android SQL DB? for example, I want to resort the Bookmarks DB. I can query the data and sort it with "Browser.BookmarkColumns.TITLE + " ASC" in the query but this will only sort the list shown to the user and will not sort the DB itself. Therefore, if a user uses my app to sort the Bookmarks by Title(ASC) and then goes to the Android Browser Bookmarks - the order will remain default (other than the one selected on my app).
View 11 Replies View RelatedI've run into an issue with an autocomplete field I'm working on.The field I'm working with is composed of the form "<NAME> (<CODE>)".When a user starts typing in text, I want to display any results that match either NAME or CODE.For example, if this list contains items and their codes, like "Personal Computer (PC)", then I'd want the list to pop up that row if the user types "P", "PC", "Per", etc.However, the problem I'm running into now is how to best sort the results that come back from this.For example, If someone enters "PC", I want "Personal Computer (PC)" to be the first result. However, if there's another row (you'll have to bear with me as this is contrived) "PC Case (301)", then there's no simple ordering I can do on the results to ensure that the best match appears first. Ordering by name and code both returns PC Case first.I want a query where it returns the best match first, rather than items in alphabetical order.Is there such a function I can use in SQLite to get this, or should I return the results and then mess with the order in the code?

View 1 Replies View RelatedI am having a weird issue. I have an ArrayAdapter which I am sorting. This displays properly on my screen, however when I check the actual data source, the contents have not been sorted. How can I ensure that sorting my ListAdapter will also sort my data source?
CODE:....
This shows that my data source hasn't been updated, even though my ListAdapter presents my ListView in the correctly sorted order.
For example:
If my data source is [10,9,1,20] after sorting my ListView will show [1,9,10,20] but the data source will still be [10,9,1,20]
On the Nexus One and I guess non-SenseUI, I could change how my contacts were sorted, "last, first" or "first last". On the EVO, I can't seem to do that. But on Favorites in the 9x grid, it sorts them "first last".
