I'm experiencing some sort of problem. Let's say I have a MediaPlayer object wich can play an audio sound and a Resources object Code....
So when I invoke mp1.start() , sound1 plays, everything's normal.
But when I try to change the sound that my MediaPlayer should play, it doesn't work, here is what I do code...
I'm pretty sure someone can see a mistake in my code.

CODE:....
This shows that my data source hasn't been updated, even though my ListAdapter presents my ListView in the correctly sorted order.
For example:
If my data source is [10,9,1,20] after sorting my ListView will show [1,9,10,20] but the data source will still be [10,9,1,20]

Why does my MediaPlayer
MediaPlayer mp = MediaPlayer.create(this, R.raw.somemusic); mp.setLooping(true); mp.start();
stop, wenn I change the layout?
setContentView(R.layout.screenoptions);
and also suddenly in my game, the sound stops. What could be the reason?
And which one is better? MediaPlayer or SoundPool?
I have a requirement to play several sounds many times in my game so instead of creating the MediaPlayer again and again I have called mp.seekTo(0) in onCompletion(mp) so that it will restart. Sometimes the sound is not audible from the device when I call mp.start () after setting mp.seekTo(0); but the player calls onCompletion() without playing any sound, this is observed randomly on most of the sounds
My sounds are of short duration mostly less than a second.
I am using a separate MediaPlayer for each sound (as I need this) -
There are almost 28 sounds in my game so i will be creating 28 MediaPlayers.
Below is the attached code for player
Also If I try to play many sounds one after the other in a short period of time i get an error saying "no more track names available". can u tell Why this is happening...?
check the below code:

I'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 3 Replies View RelatedI download some data from internet in background thread (I use AsyncTask) and display a progress dialog while downlaoding. Orientation changes, Activity is restarted and then my AsyncTask is completed.I want to dismiss the progess dialog and start a new Activity. But calling dismissDialog sometimes throws an exception (probably because the Activity was destroyed and new Activity hasn't been started yet).What is the best way to handle this kind of problem (updating UI from background thread that works even if user changes orientation)? Did someone from Google provide some "official solution"?
View 1 Replies View RelatedI've noticed a few people have complained about high standby data usage.. ie when you leave the phone on a desk, with nothing streaming, you still manage to use up 1-2mb per hour (as I was!). This is a big problem for people moving from something like a blackberry where it was hard to use up a lot of data even if you tried.I tried disabling as much as possible to see what was causing the problem (NetSentry was great for tracking usage but of course can't tell you which programs/services are using it up), and after exhausting all ideas I tried deleting the two non-GMail email accounts I had. On was set up as push Exchange, and the other a 15-minute polling POP account. I have to assume it was the Exchange that was the problem, but I can't be sure. In any case, my usage dropped from about 4MB over 3 hours to about 12kB for the last 3 hours since I disabled the accounts.In conclusion, email can be more of a problem than you think! I'm going to forward my other accounts through my GMail to see if that works better.
View 43 Replies View RelatedI have an un-branded Desire with the latest HTC OTA firmware update and it's running on T-Mobile here in the UK. I have Web n'Walk so I get the full-speed HSDPA data service when it's in range.
I also use Google Maps Navigation a lot. The problem I notice is that sometimes after setting a new route the mobile data connection to download the route data fails to fire up. I can see the mobile signal strength bars, but no 3G or HSDPA signal indicators. And of course without the data connection the new route details don't get downloaded. I usually have to power off the phone and then re-power to get around this.
It doesn't happen consistently - sometimes no problems at all. And the problem seems unrelated to signal strength.
Does anyone else experience this and has anyone found a solution?

I have an app which uses a large amount of data which has been compiled outside the app (on my main PC). The app is for my personal use so there are no complications with having to distribute data updates to other users. However, I am currently following a very convoluted and time-consuming procedure each time I want to update the data, and I wonder if anyone can suggest any ways to streamline it.
The procedure I follow whenever I want to add new data is as follows:
I enter the new data into a csv file which I maintain as the source of the relevant table in the database. I use SQLite Database Browser to import the data into an existing SQLite database. (This program does not seem to have the ability to append imported data into an existing table, so whenever a table needs updating I have to delete the existing table, then import data from the csv file into a new table, then manually edit the data types for all the fields in the table.)
I drag the icon for the database file onto the 'assets' folder of my project in Eclipse. I export the project from Eclipse as an apk file. I copy the apk file to my phone (using Astro File Manager) I uninstall the old version of the app and install the new apk.
when the app is run, code based on the example set out here copies the data from the 'assets' folder into the app's data folder; this means that each byte of data takes up two bytes in the phone's internal memory; at present this is not a problem, but could be as the volume of data grows; I wonder if there is a more memory-efficient method?
i want to ask about that can we convert the input source type data in android. my prob is here that i get the data from the url not in tags form. i fetch output in the inputsource type. after that i want to parse the data in meaningful form is this possible or not? if this possible then how can i implement?

View 1 Replies View RelatedBasically im looking to make a type of "search and opens a custom page" type app, such as when you type in a word (maybe adding in suggestions to what you are typing) , and when you click the word you desire, it opens a page made by myself with data on it.
I found an opensource of a dictionary, sounds lame, but it's a generally close idea to what i would like to create.
My question: What part of this code would i edit? and what exactly would i put at that location? also, how do I create a custom page for it to go to when it click the said word ?

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

I need to use a different datasource inside a map in Android than the google provided data. Is there a way to change the datasource to a tile based service (openstreetmap.org for example)?
Or are there other Android map APIs which are OpenSource and can be adapted (except Ericcson Mobile Maps - this doesn't work for me because of the licence)?
It doesn't have to have a server side part - a rich function library would be enough.
