Im trying to read the battery usage for all the applications in an android OS.
I've discovered that I can read them from batterystats file or batteryinfo, but I dont know how to interpret this file.
Can someone help me?
Hope official Android documentation will help:

Also, Battery Historian application mentioned in the documentation can be found by the following link:

I am a newbie android developer and need to create an app that uploads a .zip file to Google Drive, Downloaded the API but where do I add the code, and how? Please provide a code example.
What do you mean by "downloaded the api"?
Drive has some pretty good documentation on instantiating the drive client as well as an activity to demonstrate different use cases. These may be all the examples you need.
Drive Examples
You can find good examples in the documentation for the Drive API
https://developers.google.com/drive/android/examples/
Or look here: https://developers.google.com/drive/android/intro to find some more explanation about how it all works
HELP! I have looked so long and read the documentation at https://developers.google.com/sheets/reference/rest/v4/spreadsheets.values/update on how to write to a Google Sheet but I still do not understand. I do not have any code examples because I do not know how to if it is any help my question is like the android version of the IOS Write Google sheet cell question. One thing I do know is that it seems that I need to use spreadsheets.values.update as it says in the linked documentation but I need help on implementing it.
Has anybody ever used this?
Well, does anyone know how to format a ValueRange, or know how to format the command spreadsheets.values.update?
Is there a way to run the echoprint-codegen on Android or is there a Java implementation for it?
Echoprint codegen on github: https://github.com/echonest/echoprint-codegen
There is a C++ implementation for it? I just cannot figure out how to port it to Java so that I can run it on an Android device, assuming Android 2.2 and up.
Take a look at Alex Restrepo's port of Echoprint to Android. His blog posting with the technical details is here:
http://masl.cis.gvsu.edu/2012/01/25/android-echoprint/
The complete code along with a sample Android application using it can be found here:
https://github.com/gvsumasl/EchoprintForAndroid
Try this open source project by Jacquet Wong, it's written in Java and Android compatible.
http://code.google.com/p/musicg/
It handles wave spectrogram, fingeprint and other audio features with FFT and other dsp algorithms.
There are java libraries to deal with FFT / Audio which may already do what you need.
Ropy van Rijn already did this, and got slap from Shazam patent holders.
See in detail:

I will try to look here:
http://developer.echonest.com/
and then here:
http://developer.echonest.com/client_libraries.html
and after that you have downloaded the java client, this:

could be useful (sorry is italian code, but im sure you won't have problem)
I would like to be able to retrieve contents of a .txt file from the internet, and load it in an EditText. I tried using the code on this page: Reading Text File From Server on Android
It didn't work, as you might have guessed. I've read on numerous sites about this type of problem, but I can't get anything to work. Someone suggested AndroidHttpClient but I simply can't find any examples with this.
As I'm a newbie in Android programming, I would love if someone could please give me a small example.
This isn't so much of an Android question as it is a Java question. There are a few ways you could go about doing this, but the simplest might be using java.net.HttpURLConnection.
I have download Grevill gervill.jar and with my existing code follow from:
http://www.jsresources.org/examples/MidiPlayer.html
Could anyone spare a little effort to write a tutorial on loading SF2 soundbank? I would cry without a tutorial on the web.
new SF2Soundbank(new FileInputStream(new File("sb.sf2")));
Then you just load all the instruments in the synthesizer.
Do some research.
If you want to learn how this code works, download it and try it. Generate javadoc API reference docs from the source. Try to figure it out. If you have problems getting it to work, post another question like this, but include specific details of the problem you are having.
You'll get a much better response this way. Stack Overflow is not someplace to find someone to do your research work for you.
