Android :: How To Store Lots Of Longitudes On Device

Jul 26, 2010

I am looking into writing an Android app that has a database of approximately 2000 longitudes and latitudes which are effectively hard coded.I assume that once my app is installed, I can put this information into the SQLite database, but how should I distribute this information when the app is downloaded?One option I thought of was some kind of Patricia Trie to minimize the size of the data (the points will be in a number of clusters, rather than evenly distributed), but I'm not sure whether such a collection would work when there are two associated numbers to store, along with perhaps some other information such as place name.Does anyone have any thoughts, input or suggestions?

Android :: Securely Store User Data On Device?

Apr 9, 2010

I'm writing an application wherein users will sometimes make orders through it. I want to give users the option to save their billing info (name, address, etc.) so that it can be quickly restored later if they want to make another order. The user will enter a password to secure the data. Obviously I can't just put this as a file on the device, as anyone can root/find the data. Is there a built-in Android method for storing secure data that is locked with a password? If not, what is a good place to start for storing this data securely using Java?

Android :: Can't Store Hash On Database / Content In SharedPreferences Secured On Droid Device?

Sep 14, 2009

We want to store credentials for a user to a web service so the user doesn't have to repeatedly login, but we're concerned about security. We can't store a hash on the database, but we could probably use JCE encryption locally.

Is the content in SharedPreferences secured on the Android device?

Android :: Sending Lots Of SMS

Mar 23, 2010

I am working on an app that allows sending lots of text messages. I have two questions:-
1) If I send too many messages together (around 80), only about 10 actually go and the rest fail in the first try. Do networks limit how many sms can we send per second or something? Will pausing after every sms help in this case?
2) I believe Android shows a dialog box if we send more than 100 sms in an hour. I am sending SMS from a separate thread. Can Android block that thread if there are too many SMS being sent?

Android :: Improve Eclipse Performance For Projects With Lots Of Resources

Sep 13, 2009

I have notices following:

If I have a project with minimum files in res folder, the project saves quickly, compiles quickly and launches quickly. But if I have a lot of resources, my project is saving, compiling and launching during relatively long period of time. This is really frustrating if you do some minor UI updates, and you have always wait Eclipse to generate R file etc.

Android :: Need Free App To Adds Lots Of Features To Quick Search Box

Jan 18, 2010

Just wanted to let you all know about my new app. It's called Searchify, it's free, and it hooks in to the Quick Search Box (on Android 1.6 or higher) to let you do all sorts of things. Searching lets you perform translations, calculations, unit conversions, wikipedia searches, calendar entry and more just by typing in searches. Some of the things you can do with it: Unit converter: type a quantity (e.g. "10 pints" or "5 oz") into the search box to see a list of conversions. Calendar entry: Type an event in text (e.g. "tue 3pm meeting" or "tomorrow 3pm - thursday 5am event @ John's") to add it to your calendar. Translator: Type "translate" then a word or phrase in any language to see translations into languages of your choice.

Android :: When I Start To Compile Launcher Module - Lots Of Errors Occurred

Jun 17, 2009

I switched to SDK-1.5-R2, and also the source code released in May, 2009. But when I start to compile the Launcher module, lots of errors occurred.

Some classes cannot be resolved cause there are no such classes in Android.jar file. I.E. android.os.ServiceManager; android.app.ISearchManager;

and some fields inherited from parent class cannot be resolved either. I'd be very appreciated if anybody help me out of this problem.

HTC Desire :: Lots Of SMS Messages

Jun 12, 2010

I have around 3000 messages from one person, currently they are all in one conversation, because of the number it takes a few moments to load the page. I know I can set the phone up to delete the old messages, but I don't really like deleting messages, or email, I just don't like doing it. I'm looking for an app (or if the existing message app has a solution) that will allow me to have a smaller conversation or a way to load just the last few messages unless I ask to see older messages similar the the iphone. Does anyone know if this kind of thing exists?

General :: Where Does Google Play Music Store Music Files On Device

Apr 10, 2013

I have music that is playable with Google Play Music player, but not with other players. I have chosen for the music to be "on the device", and it plays when even in Airplane Mode, so I know it is not streaming, but the music files do not show up in my "Music" directory tree, or under any other file trees that I can find. I have used ES File Explorer to do a top down search for some of the missing titles, but it doesn't find them. I'm perplexed. There must be a cache somewhere, but I can't find it.

Android :: One Line Causing Lots Of Garbage Collection.String.format With Float?

Apr 13, 2009

In my ListView, there's one line of code in my ViewBinder that causes lots of garbage collection as I scroll through the list, about every two seconds...

D/dalvikvm(16312): GC freed 13171 objects / 659576 bytes in 162ms D/dalvikvm(16312): GC freed 13122 objects / 654128 bytes in 129ms D/dalvikvm(16312): GC freed 13134 objects / 655416 bytes in 142ms D/dalvikvm(16312): GC freed 13129 objects / 654840 bytes in 129ms D/dalvikvm(16312): GC freed 13149 objects / 655000 bytes in 110ms D/dalvikvm(16312): GC freed 13150 objects / 655720 bytes in 127ms D/dalvikvm(16312): GC freed 13075 objects / 652256 bytes in 111ms D/dalvikvm(16312): GC freed 13232 objects / 659040 bytes in 136ms D/dalvikvm(16312): GC freed 13106 objects / 653920 bytes in 110ms D/dalvikvm(16312): GC freed 13155 objects / 655152 bytes in 110ms

The offending code is here, which formats a price for each item in the list: String price = cursor.getString(columnIndex); final float pricef = Float.parseFloat(price); price = new StringBuffer("$").append(String.format("%. 2f",pricef)).toString(); ((TextView)view).setText(price);

If I comment out the line with String.format, the garbage collection goes away. So what's the "right" way to do this to avoid allocations? That database field holds an unformatted text string which I'm trying to format into proper currency format (example: format "1.5" to "$1.50")

Samsung Captivate :: Preparing Lots Of Apps

Jul 14, 2010

I have updated my contacts and Google Calendar in preparation for the Captivate. Anxious to get going. I have spent quite a few hours reviewing one 13 page thread of 'favorite apps', and put together a list that I interest in looking at. I have some searching to do for some things that didn't come up. Priorities are good Calendaring; Easy use of voice for calling contacts; Financial Software to track stocks. Many other things of interest. Here is what I probably will be installing for sure some time fairly quickly (not all of my interests are met in this list): NOTE: The links may take you to a descriptive site, or may take you to a review..............

Motorola Droid :: Lots Of Failed App Installs / Updates Before And After I Rooted - Fix It?

Sep 29, 2010

Lately it seems that installing or updating an app is about a 50/50 chance of failure. This is both before and after I rooted. Then I installed LithiumMod and see the same thing. It doesn't appear to be any particular apps, and I've noticed it most recently with pandora update, wow armory, angry birds lite, and others. It makes the phone very useless in the instance where I need a new app and can't get it to work.

Going to Settings > Applications > Market > Clear Data seems to work... again, 50/50. Doesn't fix it every time.

Any ideas? I've googled around and most solutions are the "clear data" method, or just "try it again".

I find that quite insane, and it just keeps going. I feel like this is also the reason why my phone is constantly overly warm. SGH-M919

Motorola Droid :: Lots Of Resetting After Recent Updates And During Phone Call / What To Do?

I noticed that facebook notifications don't work at all anymore. But since the most recent update my phone has rebooted at least 2 times a day. Most recently during a phone call? I got this phone as a refurb from Verizon after the OTA bricked my last one. Does this warrant a replacement or is it a software bug I have to track down? I honestly don't want to go through the exchange process again.
