Anyone know of an android app for kids to practice writing their letters on the screen with a fingertip? Similar to writepad or abc pocketphonics for the iphone.

I fight with me for some days about asking this question.
Its pretty plain and simple:
If you have an application with a GUI totally working on 2D drawing, what should be the best practice to handle what to draw and where to touch?!
Some example for better understanding:
I have a game with a map. On this map I can build houses and stuff.
I also have a information bar which can be extended. On the extended bar I draw some information about the game and also enables to change different values. If a touch occurs, I have to check, if the information bar is extended or not to determine if I want to change something on the map or something on the bar.
Thats done by the State Pattern, but I have some doubt if thats the right one because I think it can be a bit complex because of possible "sub-states".
So basically the question: Is the State Pattern (from GoF) the best practice to handle a pure graphical GUI?
Recently I noticed what appeared to be horizontal lines in the middle of the screen. I thought the screen was failing until I realized the lines are very, very small lines of text. How to remove these lines of text?

I need to be able to access this info from my Incredible or from a computer over the internet. Is there anything like this out there? I don't care if it costs a little $ as long as it works. It needs to be able to run without his noticing it.

I've tried updating the software from my laptop and i think it updated it but i couldn't tell because i can't see anything lol but it's still the same. i haven't dropped it or anything so i haven't got a clue why it's suddenly stopped working.....

View 3 Replies View RelatedI have a tab 2 10.1 with the latest software from Rogers in Canada.My problem is, my daughter is 16 months and loves to play games on it but "ALWAYS" hits the back button or home button or the advertisments etc.Then it kicks her out of the games, it is very fruastrating as I am a Android fan, but I see IPADs that when in kid mode, the kid "CANNOT" get out of the games.
Is there a APP, or mode I am missing, I have tried 2 different APPs and both SUCK and allow her to still get to Home screen or hit advertisments or freeze the games.
I purchased these mainly for my kids and wife and am starting to hate them for very poor usability features that IPADs do not have problems with? And I have used IPAD's and really really hate APPLE's software.
With all the ads in games these days taking you out to the internet to browse and buy things, is there any way to disable internet borwsing from an actual browser while still leaving it open for things like Youtube? I can't uninstall the browser itself I don't think but if there's a way to disable it, or even just to disable downloading files from the internet, I'd be interested in that.

View 2 Replies View RelatedI have a sizable install base already on some apps with Android 1.5 set as the minimum version. I want to update the apps to take advantage of some of the newer features offered in Android 2.0 and greater. What is the best way forward so I don't break things for my current 1.5 and 1.6 users?
If I simply update the application with a new min SDK version, will 1.5 and 1.6 users be prompted to uninstall? Or will they just not see the update? What about future development that I want to apply for everyone, say a bugfix. Will I have painted myself into a corner? Another solution would be to fork and create a new app for 2.0 users, but that is undesirable for several reasons.
I have had my Desire no for almost 2 months, and like most I have tried installing and uninstalling many apps, to see what I like.Due to doing a factory reset on my phone yesterday I have layered back all the apps I was using and have noticed that I have used considerably less memory than before, making me very suspicious of the uninstall method used within the market place.Does it leave behind pieces of the app, and if so what's the cleanest method of uninstalling apps.
View 7 Replies View RelatedI've been scouring the web looking for information on setting up a peer-to-peer connection between Android handsets and so far have drawn a blank. The only thing I can definitively seem to work out is that it was made a whole lot more difficult when XMPP was removed from 1.0. Apart from that, I find a couple of threads on an OpenIntents board about porting an XMPP implementation to Android that were last posted nearly 2 years ago. Has anybody solved this problem effectively? What's the best way of doing it (from a games point of view)?
View 7 Replies View RelatedI'm writing an application where real-time knowledge of the GPS state is critical to convey to the user. I request GPS updates at 1000 ms intervals -- when I haven't received another update 1500 ms past the most recent update, I want to display a yellow icon, and 5000 ms after the most recent update I want to display a red icon. Currently, I'm doing it like this: private CountDownTimer gpstimeout; public void onLocationChanged(Location location) { if (gpstimeout != null) gpstimeout.cancel(); gpstimeout = new CountDownTimer(5000, 1500) { public void onTick(long m) { setYellow(); } public void onFinish() { setRed(); } }; gpstimeout.start(); }
View 3 Replies View RelatedWhat is considered "best practice" when executing queries on a SQLite db within an Android app? Is it safe to run inserts, deletes and select queries from an AsyncTask's doInBackground ? Or should I use the UI Thread? I suppose that db queries can be "heavy" and should not use the UI thread as it can lock up the app - resulting in an ANR. If I have several AsyncTasks, should they share a connection or should they open a connection each?
View 3 Replies View RelatedI'm new to developing Android applications, and have only a little experience with Java in school. I was redirected to StackOverflow from the Google groups page when I was looking for the Android Beginners group. I have a question about what is best practice to pull content from a web source and parse it. Firstly, I would eventually like to have my application threaded (by use of Handler?), however, my issue now is that the class I have created (Server) to connect and fetch content often fails to retrieve the content, which causes my JSON parser class (JSONParser) to fail, and my View to display nothing. After navigating to the previous Activity, and attempting to call the connect(), fetch(), and parse() methods on the same remote URI, it will work. Why does this (sometimes retrieve the remote data) happen sometimes, but not always? What is the best practice, including the use of ProgressDialog and the internal Handler class, to make my application seemless to the user. Is this the best place to ask this question?
View 1 Replies View RelatedI am creating a database driven app for managing people. I am showing a list of people with each name in a TextView. When a TextView is clicked, I launch a new intent to show the detail for the person. My question: What's the best practices for passing the id of the person to the new intent? The TextView is displaying the name of the person, so how do I know the id of the person? Once I know the id, I know how to pass it to the new intent, but I don't know what the best way to associate the id of the person to the TextView. Is there a best practice for this?
View 2 Replies View RelatedIn general, I'm very impressed with Android's default text to speech engine (i.e., com.svox.pico). As expected, it mispronounces some words (as do I) and it therefore occasionally needs some pronunciation guidance. So I'm wondering about best practices for phonetically spelling out those words that the pico TTS engine mispronounces. For example, the correct pronunciation of the bird Chachalaca is CHAH-chah-LAH-kah. Here is what the TTS engine produces: mTts.speak("Chachalaca", TextToSpeech.QUEUE_ADD, null); // output: chuh-KAL-uh-KUH mTts.speak("CHAH-chah-LAH-kah", TextToSpeech.QUEUE_ADD, null); // output: CHAH-chah-EL-AY-AYCH-dash-kuh mTts.speak("CHAHchahLAHkah", TextToSpeech.QUEUE_ADD, null); // output: CHA-chah-LAH-ka mTts.speak("CHAH chah LOCKah", TextToSpeech.QUEUE_ADD, null); // output: CHAH-chah-LAH-kah Here are my questions. Is there a standard phonetic spelling recognized by the Android TTS engine? If not, are there some general rules for making custom pronunciation spellings that will make the spellings more likely to be correct in future TTS engines/versions? It appears that the Android TTS engine ignores text case. What is the best way to specify emphasis?

View 9 Replies View RelatedI am quite new to Android and Java. Before I was working with C++ where the events where dispatched with messages. Now I would like to create the same user experience for Android platform and I would appreciate any of your suggestions or comments on what is the best way to bind events to user controls.
Here is an example from C++:
ON_MESSAGE(WM_RECORD_START, &CMainFrame::OnRecordStart)//Method OnRecordStarts() executes on WM_RECORD_START_MESSAGE...................
Some of my app's preferences could use some more explanation than the scarce space available for the summary. Sadly, there doesn't seem to be support from the system, like an optional help button that shows a longer text. How do you solve this problem? The first thing that comes to mind is an additional custom "preference" like "more information to above entry" that opens an AlertDialog with the help text, but that's not really nice for both user (two entries for the same preference) and the developer (manual work to do in Preference Activity). A bit nicer for the user, but way more work for the developer would be custom dialogs for each preference with more text and/or a help button. Is there a better solution or even an officially recommended best practice?
View 7 Replies View RelatedWhat is the best way to release two versions of an application? E.g. a free version with limited features, and a paid version with the full feature set. #ifdef would be the ideal way to do this, but Java doesn't support it. Could I do something like: try {import com.foo.myapplication.ExtraFeatures; } catch (Exception e) { // ignore it, this must be the free version}? I could manage with this kind of construct, although #ifdef really would be ideal.
View 10 Replies View RelatedI didn't use much Java before Android so my knowledge concerning the gc is marginal. Now I'm developing a highly physics-based game and therefore I need to do many calculations each time step and many (25) time steps per second. At the moment I'm almost only using local objects (float) in my methods, so I guess they are allocated every time the method is called (which might be, for example, 25*100 = 2500 times a second , for 100 objects with calculations on them). This causes massive activity of the garbage collector like freeing ~10000 objects every 1-2 seconds (taking ~200ms on a real device). Now I really want to optimize that because even there's no noticeable delay due to the GC (and the frame rate is constant), this seems just not well. But I read on many documentations concerning Java optimization, that there is not much to optimize in modern versions of (desktop) Java, because the GC is fast enough. Does this apply to Android, too? Does the compiler optimize anything like frequently, steady allocated objects (like floats)? What would be best practice: keep all local objects and allocate and free them all the time or use class-global objects, even if they are only used inside one particular method (which is bad programming style but conserves GC?
