Android :: SQLite On Union With Limits Alternative
Jul 26, 2010
I want to create a Cursor, which later I will pass via CursorAdapter to AutoCompleteTextView for autocompletion suggestions. The problem is that my SQL statement needs to select 2 different result sets from the same table, just sorted by different criteria. At the same time these result sets must not overlap - otherwise I would have multiple same suggestions. On MySQL, this would be quite easy: In this case I would have always up to 10 unique values. On SQLite, unfortunately, this is not the case - I cannot have limits on particular selects, just on the whole result set, which makes then UNION not useful for this case at all. solve this problem I've thought about making 2 queries separately: iterating through Cursor from 1st query and putting values into an Array, then iterating over Cursor from 2nd query and also putting values into the same array while checking and skipping already existing values in Array to avoid the duplicates. Then use ArrayAdapter to pass values to AutoCompleteTextView. Theoretically this would work - but what I don't like that everything becomes more complex and much more code to write to solve such a simple task.Is there maybe a better and easier way to do it?

1) Our Android app will store data in a built-in SQLite DB. I see the DB can throw android.database.sqlite.SQLiteFullException, but there's no exact info in API what is the limit. Could anyone tell what are the size limits for a DB in order not to get into the SQLiteFullException? I assume DB will store data in device's internal storage (versus SDCard). Am I right? Given SQLite DB is just a file, probably the DB size is limited with free internal storage space. Again - Am I right? If yes, then what is the internal storage size on Android? How to detect it? Does it vary on a device model basis or OS version basis? 2) We'll also need to save app settings. I think SharedPreferences will fit nicely. However the question is - are SharedPreferences saved to the internal storage too? If yes, then is it the same storage where the DB stores its file?

I am currently considering to develop an application for processing of images captured by the camera of mobile phones using the Android OS. Before I make the decision to go forth, I have done some research and found out there are some complaints regarding the limits of the memory allocated by the Dalvik VM, which seem to be limiting to applications that require manipulation and processing of images. Which limits should i have in mind if i would have to process for example 3 photos taken with the camera, in my process, applying filters, transforms and other types of mathematical operations?I would like to know if it is possible to change the default value of
memory allocated by the Dalvik VM for each application (this default is of 16 MB), in any way, using the Android 1.6 OS. Has anybody looked into this that can help me out please? I have also read in the Android 2.1 compatibility definition document
(available here: http://static.googleusercontent.com/external_content/untrusted_dlcp/source.android.com/pt-PT//compatibility/android-2.1-cdd.pdf )that it is possible to change the allocation of memory by the Dalvik VM from 16 MB to 24 MB or even a bigger amount if it is necessary, but t is not mentioned anywhere how this can be done. If someone has looked into those issues before.

I wanted to create an gallery with images.The images within the gallery should be zoomable and pannable. I could able to pinch-zoom an image but could not able to set zoom limitand prevent the image from being panned off the screen. I used the following code to zoom an image:http://code.google.com/p/4chan-image browser/source/browse/src/se/robertfoss/MultiTouch/TouchImageView.javaspec=svnd3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5&r=d3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5 First approach : I used TouchImageView to supply images to gallery, this allows me to pinch zoom but can't scroll the gallery. i.e I cant differentiate between 'single tab event' and 'tab to scroll event'

Is there anyway to increase mms message size? On my old TP2 I had my limit set at 5mb and I didn't have an issue Sprint to Sprint, only sometimes with Verizon. With the evo, and recorder set on minimum resolution I can't even send a 10 second clip!I've tried handset which only gets me up to 1.2mb. I need it at 3 at the very least.

So with at&t you can't download apps and podcasts over their network if they are over 10mb, so how about with Verizon?

Didnt see an existing thread on this; sorry if this is a repeat.By default the SF stores 200 texts per conversation and 20 multimedias per conversion. However, that value can in both cases be adjusted up to 5000. Might be excessive but here's how if you haven't already done it: Open Messaging App>Menu>Settings>Text Message Limit>Tap the number and put in 5000>Set and you're done. **If you put in a value greater than 5000 it still ends up as 5000; must be the limit** With 5000 thats gonna be some really long threads but oh well.

I've searched and no one has addressed this topic (which has me worried). I was using my native mail (not Gmail) app last night and needed to copy three paragraphs from a received email into an outbound message for a client. When viewing the received message I went through the process to copy, long hold screen, highlight text with finger, release, "copied to clipboard".. great. Transfer to new message, long hold screen, PASTE. Excellent, wait, no I only see it pasting HALF OF THE LAST PARAGRAPH. Umm what happened to the other 2.5 paragraphs? Let's try again, oops same result.... WTF!? Is the Hero limited to the number of characters copied to clipboard? Is ANYONE else experiencing this?

First post here. First Android phone as well. Picked up the X yesterday and am enjoying it. One quick question though, can I not turn the phone to the right (bottom keys to the left) to change the orientation? Things only turn when I turn the phone left or straight up, not right or upside down.

Just would like to hear your idea about that...I recently have seen the Samsung Galaxy S and , well, was really impressed about that! Then I have seen the new HTC Desire and heard good rumors about that. So, I was wondering, which one would you take as an alternative to the i Phone 4G? I have seen some price alternatives for Samsung Contract Mobile Phones galaxy s: compare models and prices contract mobile phones galaxy s. - Choppy Doo and HTC Contract Mobile Phones htc desire: compare models and prices contract mobile phones htc desire. - Choppy Doo What would you take if you were in my shoes?

My company has blocked access to SMS messages on our phones, yet we have an unlimited data plan. Does anyone know of an alternative program you can use for SMS type messages that you don't get charged for per message?

I just picked up the Motorola Droid, and I'm loving it.I'm trying to find the best free alternative to SMS (because it's ridiculous that after paying $30/mo for 3G access, I have to pay more to move 100-character messages around on the same network...).Ideal would be something like BlackBerry Messenger.So far, I've been using gTalk with my status set to invisible, and that seems to be a pretty good alternative. When I initiate a gTalk conversation with an invisible status, the conversation usually remains short - like an SMS conversation. One downside is that people never initiate conversations on gTalk with me while I'm set to invisible.

I see posts saying that FrameLayout is the alternative, and that I should use margins to position things (this strikes me as wildly counter intuitive, but ok... if it works, I'll take it). However, I can't get it to work, so, I'm looking for assistance. I'm aware of the fact that this may mean different things on different devices. I'm ok with that. I simply need a way to, programatically, and at run time, place an item at a SPECIFIC location. I don't want to rely on gravity (or the laws of thermodynamics). I just want to specify a location and have the element appear there :)

One of the alternative app stores is asking for unaltered, unedited capture from the app as a video. Plus I'm also interested in cleaner video than I get by focusing a camcorder on an Android on a table. Who knows how to do that? I think I found some posts that indicate Mark Murphy may have solved this with a tool that goes through DDMS. If so, I'll get that tool and donate.

I have tried using both launcher pro and ADW launcher, who have a reputation of being light launchers, and no matter how much I mess about with the settings, I always experience the same thing:
1: They are often not fluid when swiping screens, showing a little sign of lag or sluggishness that you do not experience with the Sense UI and which drives me crazy.
2: When unlocking the phones, the first swipe is always followed by a noticeable amount of latency.
This bothers me quite a bit, because I really like these launchers and I know of no other way to get the (from my POV) main advantage behind them (the dock).Any advice? I have tried messing about with the memory settings etc to no avail.

I would really like an unlock screen that requires a code (much like the iphone one). I find that the unlock pattern is not as effective due to the fact that the screen smudges, allowing others to see what your pattern is.
