i am doing really important app and i need to ask you, if is there some way, how to switch between java files from one BUTTON with one iD..
Look on this picture for clear: http://imageshack.us/photo/my-images/811/radab.png/ (i've uploaded it on imageshack because i don't have reputation..
I am new to the ANDROID developing and i really need your help to the beggining.
Thanks a lot.
Thanks for your help.
The Java Package name hierarchy is not meant to be a place to hardcode your database of movies into.
Preferably, learn to use SQLite for keeping that kind of data. Don't even bother using XML in this case.
Take a look at this tutorial.

I need to merge two audio files together. Basically place one audio file on top of another and make one file. I have seen some posts on concatenating two audio files, but none on this. Thanks for any help.
I recommend you take a look at JSyn. I would discourage you to attempt to do it yourself, since it can get complicated with multiple audio formats. It supports a lot more as well.
This worked for me. Use jresources.org to help you. You could use their example: http://www.jsresources.org/examples/MixingAudioInputStream.java.html. For the org.tritonus.share.sampled.TConversionTool package, if you have problems using their library, then download their source code (http://sourceforge.net/projects/tritonus/files/): it's open source, and try using it. I tried it and it worked for me :D. I'm grateful for those guys!
I'm hoping this will be a fairly basic question. I've been playing around with android development in the last couple days and I'm still missing some of the simple things.
I'm working on an app which needs to convert between currencies. I know that I can get recent data with queries like this.
I want to be able to save this information and allow it to be updated on request. I feel like the natural way to do this would be using an android resource file. It would be ideal if someone could (as explicitly as possible) explain how I could make the query, save it to a resource file, and then read the conversion rates from the resource file in the future.
I understand I could just make the request live each time the data is needed but I'd prefer to have something saved (so the rates can be used offline).
Thanks in advance all.
UPDATE:
Though Vulovic's answer is correct, and I intend to use this approach in the future. For now I have found it is simple to implement the SharedPreference class to store Currency:Rate data.
Ok, you need to create SQLite database. Here is a good tutorial: http://www.tutorialspoint.com/android/android_sqlite_database.htm
I am new to Android development and have been struggling with a problem. I have been trying to learn how to save user inputs to file. I have asked a similar answer and ended up figuring out a solution although it didn't work out the way I want. I have been searching high and low about how to write files to xml. I would to have a user be able to save, add, retreive, and be able to remove items from an XML file. I think the problem I am having as far as learning this is I'm not sure what the processes are call to properly look for a solution. This isn't for school work, I'm not looking for anyone to write up some code for me. What I am hoping for is proper terminology, maybe a link to some helpful information and such. I believe this process is called parsing, and you can add to XML through appending, not sure about much after this. Thank you in advance to anyone who can offer assistance.
To have the XML always available for the app you should put it in the "assets" folder. You should copy-paste the xml file to modify it, to ensure the file won't be corrupted afterwards.
First you have to copy the xml to the sdcard (preferably to a folder with your app name as folder name), you can use this to learn how to copy a file. After you have done that you can use the JDOM Parser to modify that xml file.
Put the xml after the modification back in the assets folder.
I have a tiff image with many directories and subdirectories. I would like to navigate this tiff directory tree and import the image into a 2D array, so I can process this image. I am relatively new to java and cannot figure out how to do this. Will someone please reply to my question with a tutorial and examples of code?
Also, does anyone else find the java API documentation difficult to find, difficult to navigate, and somewhat sparse? I am trying to do this as a workaround for a processing sketch I am creating. Are there different workarounds?
Thank you.
Well i didn't even know a tiff could have directories and sub directories... But I would have a look in java File class as a start point to try to see those directories from your app. If you can see them, than you probably can parse them too.
