I need to attach several text files with the apk so that these text files can be stored at SD card when APK is installed. How can I do it?

Is this something I would have to provision programatically at runtime?

View 1 Replies View RelatedCurrently I supply a user with a URL to click on to download my j2me application. This URL includes their user id as a parameter, a servlet takes this information and dynamically creates a jad file that includes this user id , thus making the user id available to the j2me app.
However, I am now using j2me polish to compile my program and thus have the compiled .apk for this same program. However, I cannot work out how to make this information accessible to the the compiled program as there is no jad / jar mechanism. The information is only available at the time of download.
Any suggestions gratefully received! (is this even possible in an android application?)
I'm working on an Android application that has several Activities. In it I have a class with several static methods. I would like to be able to call these methods from the different Activities. I'm using the static methods to load data from an xml file via a XmlResourceParser. To create a XmlResourceParser requires a call on the Application Context. So my question is, what is the best way to get a reference to the Application Context into the static methods? Have each Activity get it and pass it in? Store it somehow in a global variable?

Toast toast = Toast.makeText(context, text, duration);

I'm having some issues with the old "Cannot make a static reference to a non-static method" error in my Android program. I am creating a sand falling game (similar to the Powder Game) and I created a class called Control to create a Control Bar at the bottom of the screen with a slider for brush size (that works fine) and a button to pop up a Dialog to allow users to pick the selected element. However, when I call DemoActivity.showDialog(2) from my code, it gives the static reference to non-static error (DemoActivity is the main activity of my application). I also tried changing it to just Activity.showDialog(2), but I got exactly the same error!
Here's my code:
CODE:................
I fixed it by adding the following to my Control.java code:

And then calling control.setActivity(this); from my onResume section of DemoActivity.java!

I get this error:
code:.............
This error is line 13 on the second box.
I have Eclipse Juno and I'm working on an app with that.
The main activity will have a scrollable menu that takes you to all the other activities.
So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.
Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)
- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
- Item ??: Centred, bold, non selectable title (Tools)
- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.
I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.
I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.
I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C

View 1 Replies View RelatedI have been finding it convenient to extend Handler in many of my activities to handle messages specific to the activity. The handler sublass is an inner class of the activity and needs to access its state. I am wondering if there is any performance difference between making the handler subclass static and passing in the activity explicitly in its constructor or making the subclass an "instance class" and letting the vm worry about my accessing members of the containing activity.
The static approach:

I am thinking to create a static method to return a reference to the application instance. I am not sure if it is safe to assume there is only one instance of the Application in one application. Apparently, the Application class in Android SDK doesn't provide such method to return the instance reference. So I suspect there must be a reason?
View 1 Replies View RelatedIn my application, I am going to create a few listviews that are dependent on the listview before it. For example,Then, depending on user choice, will go next screen, let's say, it contains a submenu of each type of school,that may be different or may be the same to other states.What I want to know, is how to populate these different lists dynamically as the user goes on? I don't know what the best of doing this is, and I seem to be looking in the all the wrong places because I keep getting stuck. Once all the data is added into whatever structure is used, it will be static. I basically just need help as to how to code information into some sort of hashtable or anything of the sort that can be easily referenced, and later when the Application is updated, be able to add more schools/states/submenus etc.

I have a new Galaxy S. If I go to Market and install an application, everything is done automatically without giving me options.
So, my questions:
a. What is/are the files that are downloaded?
b. Where are files saved to?
c. What happens during installation? Is there just one binary? Or a binary with lots of other files? How can I find out the files that belong to a particular application.
If it is a paid application, how can I save it so that I can reinstall again. I am having so much trouble learning this new phone that I have to restore it to factory state already twice on the first day.

View 3 Replies View RelatedWhen I added the JExcelAPI http://jexcelapi.sourceforge.net/ to the class path and run my app.
I get: trouble writing output: shouldn't happen [2009-07-16 14:32:19 - xxx] Conversion to Dalvik format failed with error 2.
What will be the best storage choice for an application with huge amount of mb in media? The application will not be in android market.
First choice was to use assets/ folder. At least, 160MB of audio is shipped with the application. When I moved all the media to the assets/ folder, I end up with:
"Conversion to Dalvik format failed: Unable to execute dex: null"
And reading: http://code.google.com/p/android/issues/detail?id=2328 suggest me that maybe it's not such a good idea to ship all the media in an .apk file. I think that the problem has nothing to do with large .java files, as it arises when I copy the bunch of audio to assets/.
I was thinking in using the sd card storage. But, I don't want the user to accidentally remove the media files. I want it to be private, not accesible to possible deletions. So, another approach is to use the private storage and download the media in the application first run, or something like that.
I've created an application which uses around 15 small audio files. Right now I'm using mp3 files and each is around 200KB. These files are stored in my res/raw directory. I'm using SoundPool class to play the files in my application. I'm hoping to put this application on the android market place. Can one of you suggest what is the best way to store so many audio files? Will my application be scalable? Is wav or ogg format better approach instead of mp3? Please let me know.
