Was going through some apps, I found out there was one application with validation, lets say we validate the data on web, similarly can anyone suggest and show a piece of code so that can get it how to do it.

View 2 Replies View RelatedI'm an android developer trying to use the javax.crypto package to encrypt/decrypt my SQLite database backups when I put them on the SD Card.That way, they can't be read while they're in the publicly accessible file system.I can encrypt/decrypt the file just fine, but I have no idea how to tell if the user input the right key or the wrong key. An incorrect key just returns a more jumbled file. I need a way of validating the user's password without storing it on the device (since they could be importing to another device).How can I check to see if the file has been successfully and correctly decrypted?
View 1 Replies View RelatedI need to do form input validation on a series of EditTexts. I'm using OnFocusChangeListeners to trigger the validation after the user types into each one, but this doesn't behave as desired for the last EditText. If I click on the "Done" button while typing into the final EditText then the InputMethod is disconnected, but technically focus is never lost on the EditText (and so validation never occurs).

View 3 Replies View RelatedIf I want to enforce a maximum length of input in an EditText field, I can use the maxLength attribute. But if I want to enforce a minimum length (in my case, simply non-blank), I find no corresponding minLength attribute. I've also looked at the various 'inputType' attributes (phone, password, etc) but I don't see anything like 'required' or 'non-blank'. I can't believe this would require a custom input filter; it's more likely the answer is so obvious it just doesn't get written down in the form I'm asking the question.

View 2 Replies View RelatedIs there any Java validator libraries i can use to validate text input from an android app?
i know that in spring there are validators for various different types such as checking if a value is a int, if a value is a valid email, etc etc.
Anything similar in core Java or even android?
cheers in advance. i don't want to re-invent the wheel if its already been implemented. i could always sue Java reg expressions to construct my own ones but was wondering if their was one done specifically for email formats.
What's the best practice to validate an e-mail address (e.g. from an user input field) in Android? org.apache.commons.validator.routines.EmailValidator doesn't seem to be available. Are there any other libraries doing this which are included in Android already or would I have to use RegExp?
View 4 Replies View RelatedI'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

View 1 Replies View RelatedHow I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results.
What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content).
This is what my code looks like simpliefied with the most important parts (I think).

For my CS bachelors I am doing a Senior project using android and google maps.My vision was to do a (relatively) simple Dijkstra shortest path using google maps road data. I was going to add elevation change along with 2D distance. I am doing well playing with maps in android but I am completely stumped trying to access google maps data in any sort of searchable form.How would I go about accessing the data for say intersections of roads (lat/long) in a particular area?There has to be a way to pull that data in some sort of tree form. It seems like it may be possible with kml?Any pointers would be awesome.I want my paths to follow roads but If i cant this is going to turn into an orienteering application fairly fast.

View 4 Replies View Relatedto start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.
But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.

Can anyone help explain what this does? I did a small search around the internet, and it came up with just about nothing.My first question is: I turned mobile data off, and yet, during the night, I was charged for data, so something leaked.Personally, I thought if this was because of this particular function. But maybe it was something else.So, I turned it off, but around the forums for other androids people seem to think that syncing doesn't work as well with this disabled.Does anybody know what might have happened? And could this function have been the thing that caused the leak.The leak, was actually for only 50 KB or so, but because I'm on Page Plus, it caused me to go under the required balance to refill of $29.95 and caused my plan to lapse. It's important for me for this not to happen again. Can anyone give any tips?
View 2 Replies View RelatedI just signed up for these forums because soon I will be an HTC Desire owner in Canada. Having never owned a smartphone before I do have a few questions. The plan I intend on signing up for is the Telus Student 40 and that will come with only 100mb of data. Now I don't see myself being too data using heavy so I feel like I will be able to live with it. However I do have some questions regarding my data consumption.
1. Is it possible to completely stop all data usage by somehow disabling the data connection if I find myself reaching my limit?
2. What are ways to track my data usage to make sure I don't use too much data?
3. What are good ways to conserve data usage? I'm getting the feeling that there are some applications that will constantly be sending data back and forth updating themselves, is it possible to have these applications but stop them from constantly updating and only have them update when I want to access the application?.........
I have an application with a lot of media data (images and videos) that were previously stored on the sdcard. With that, images and videos are displayed fine in my app.
Now, in order to secure the content more, I wanted to move the content to the internal storage / data dir of the app, which I did. I copied all media with a routine within my app to the data folder (/data/data/com.myapp/some/folders/video.mp4) and adjusted the path in my app so that it would look for the media in the internal storage data directory and not the sdcard anymore.
Everything works fine, images are being displayed (decoded) properly, but videos don't play. They files do exist though - I do not get a FileNotFound exception. But an IOException: java.io.IOException: Prepare failed.: status=0xFFFFFFFC
Why is that? Everything is handled within my one app and the videos have been copied with the same routine as the images, thus having the same permission settings. Looking at the stack trace, it all runs in process id 18060).
Why I cannot playback the video from internal storage? Or how can I?
