Android :: Combination Of Multiple Values In Managed Query
May 20, 2010I've got a database. In its "tags" column, rows can have a combination of multiple values "A, B, C"--such that: row 1 has "A" row 2 has "A, C" row 3 has "B, A" and so on, in various permutations. I am trying to implement search using a managedQuery such that I can return a cursor that contains rows with one or more values in the query. For example, if the user enters "C, A" for a search, s/he should get all rows that have A, C, or A and C. I'm splitting the user query on the comma (",") character, and the final call is as follows (parameters replaced by actual values):
mActivity.managedQuery("content_uri", [id, title, tags], "title LIKE ? OR tags LIKE ?", [%A% OR %C%, %A% OR %C%], "title ASC")
Even though there are rows in the database that contain A, C, or A and C--the managedQuery returns nothing. Thankfully, if the query is for "A", or for "C", the appropriate rows with "A" or "C" or "A and C" are returned. It's just that a query with more than one search term returns nothing. What am I doing wrong here? My guess is that %A% OR %C% is incorrect logic, but why?
Android : Put Query In A Loop To Return Result Set One By One?
Nov 18, 2010I 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.

Sep 10, 2010Do the Android users have the chance to reset the NetworkProvider, so that the location will be null?
I came up with the idea, that its only possible to have that location null, after starting the device the very first time. But also than google will check the location right away for my opinion.
Sure, I'm implementing a default location for this rare case. I just want to know how seldom this case is.

Android :: BitmapFactory.decodeStream(inputStream) Always Return Null When Some Bytes Are Wrong
Aug 30, 2010I'm building an android app and I'm currently having trouble retrieving a bitmap from an URL.
Here is the code I'm using :
CODE:..........
Everything works fine when the picture's write but when some bytes are wrong, result gets null. I think it's basically expectable as it's written this in the doc of BitmapFactory.decodeStream :
If the input stream is null, or cannot be used to decode a bitmap, the function returns null. The stream's position will be where ever it was after the encoded data was read.
The problem is, my wrong picture is well interpreted by my web browser and I can do so on iPhone platform.
Is there a way to sort of ignore those wrong pixels? maybe with the option parameter?

Android :: ARCHOS 5 - MediaPlayer Create Method Returns Null
Oct 16, 2009my app is working perfectly and playing its music in the 1.5 and 1.6 emulators, my ADP1, and for everyone in the Android Market (at least there were no complaints). The problem is that when the app is run on the ARCHOS 5 tabled, the MediaPlayer.create(Context context, int resid) method returns null. I guess there might be a problem with the ARCHOS' Android implementation, but did anyone experience the same problem? What might be a possible reason for the create method to return false? The docs don't say anything. I'm also using SoundPool in parallel with MediaPlayer if that's relevant.
View 2 Replies View RelatedAndroid :: View Get Drawing Cache Method Always Returns Null
May 12, 2010I'm working with Android 2.1 and have the following problem:
Using the method View.getDrawingCache() always returns null. getDrawingCache() should return a Bitmap, which is the presentation of View's content.
Example code:
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final View view = findViewById(R.id.ImageView01);
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
final Bitmap bmp = view.getDrawingCache();
System.out.println(bmp);
}
I've already tried different ways to configure the View object for generating the drawing cache (e.g. View.setWillNotDraw(boolean) and View.setWillNotCacheDrawing(boolean)), but nothing works. What is the right way, or what I'm doing wrong? In real code I want to apply getDrawingCache() on a ViewGroup like RelativeLayout. Is the behaviour the same when using a ViewGroup?

Android :: Android - Safe To Create Static Method To Return Application Instance?
Sep 3, 2010I am thinking to create a static method to return a reference to the application instance.

Apparently, the Application class in Android SDK doesn't provide such method to return the instance reference. So I suspect there must be a reason?

View 2 Replies View RelatedAndroid :: RAC Traffic Application - Managed To Use Alternate Route
Oct 18, 2010I'd just like to sing the praises of the RAC Traffic app. It's bloody useful, especially for those who have a commute along the British motorways. Last week, I set off towards the M40 in Warwickshire and hit a bit of traffic. Unusual for 7:35am along that route. The traffic started building up and I started to panic in-case I was late for work. So, I got the Wildfire out, loaded the RAC Traffic app and had a look. 90 minute delays on the M40 Southbound. As I was going North, I stayed in the traffic jam. Needless to say, where the roundabout was that split the North and South traffic there was absolutely no traffic going my way.
Extremely useful as I stopped panicking and just listened to Last FM (via Bluetooth). It happened again this weekend, too! We were going on a trip (around 45 minute drive) and we hit traffic. Got the phone out, looked at the traffic, and managed to use an alternate route through the residential areas using my SatNav. I'd strongly recommend this application to anyone who has to do a bit of driving/has a lengthy commute.
HTC Tattoo :: Managed To Get Photoshop App
Feb 12, 2010Has anyone managed to get the photoshop app on their tattoo yet?I have been looking and it still is not in android market on the tattoo. I looked on the adobe site to see I could download it from the website onto my computer as I have done for some other apps that are not in the market. Not there they just direct to the android market.I then found the adobe android app forum and asked about it saying that I wanted it for the tattoo. I had a reply that it is compatible with tattoo and that I should get it from the android market. I replied to that saying that it was not there and could they get it put in.No response yet and it has been a week. I will try again soon but just wondered if anyone had found somewhere else to get it?

Jul 9, 2012Yesterday after turning on wi-fi on my EVO 3D, there was a system update notification. Yes, it was the long awaited ICS. Since it was very late I didnt play around it with it till today. When i did, i noticed that play store wont update my apps anymore due to 921 error. Quick google search suggested that i delete cache and reinstall app. Well, i managed to remove the app somehow (even though i got "was not removed successfully message"), because whenever I press the Play Store icon, the message "the linked program is no longer installed on your phone" appears. I have no clue how to get this back. To be honest i dont understand how a user can be allowed to remove such a vital app...
View 5 Replies View RelatedAndroid :: How To Keep GPS Active Until More Accurate Location Is Provided?
Jan 2, 2010I recently posted this question on stackoverflow (http://tinyurl.com/ yzrofne), but maybe someone here can help me. I am using the location manager's requestLocationUpdates() method to receive an intent to my broadcast receiver periodically. The system is correctly firing the intent to my broadcast receiver, and I have been able to use it correctly. The only problem is that the GPS location provider only stays active for a few seconds after the initial location acquisition, and I need it to stay on a little longer so that the location estimates are more accurate. For example, if I tell the location manager that I want an update every 5 minutes, it correctly fires the intent with location information from the GPS. However, the GPS only stays active for about 5 seconds, so it doesn't give much time for the location to reach a high accuracy (say, less than 10-20 meters). My question is how to make the GPS location provider stay active for each periodic request that comes from the LocationManager requestLocationUpdates. Does anyone know how to do this?
