Hard to tell. Somewhere you're creating objects without ever releasing them. Are you endlessly adding to a list or something?
System.out.println(""+java.lang.Runtime.getRuntime());What are those calls good for?
And may I suggest you to stick to the Java coding conventions (lower-case method and variable names) and generally find better names for your classes and methods?

Can anybody help with some subtleties to this code?

Hello,
I was wondering if anyone could take a look at the code in general for me, which is to go in an 'effects' pedal. The first while loop is for a footswitch that either reads high or low. It controls the mode of the pedal. the first mode is the default, where no signal manipulation occurs, and what comes in the audio input just comes out; the second mode stores data (fundamental frequency, average FFT amplitude from 3 kHz to 5 kHz) from the E string of a guitar, which is plucked after that mode is actuated; the third mode does the same for the A string; and the final mode takes in a note on the E or string, recognizes it as either on the E or A string, and adjusts the frequency content to be in tune based the data stored in modes 2 and 3. then the new magnitude vector is put through an inverse FFT and output through the DAC and sounded.
What I'm curious to know is, are there any blatant errors I've made? Will the signal coming out of the inverse FFT be sounded through the DAC? does it need to be changed from a double to an I32? I am trying to debug, but right now I'm having problems getting the correct output voltages on the Blackfin (the SPORT 0 pinout doesn't seem to match what is on the board....).
also, I was wondering if I will lose any phase information on the signal that I get out compared to the signal I put in. Will it be detectable by ear? Or would it all sound the same? along with the phase change for some signals, using an inverse FFT resulted in a loss of amplitude (from about 1 to on the order of 10^-5. that's a lot!). but when the test program was played on my computer, the phase change was not noticeable from the output signal, and neither was the magnitude change! the output played at the same volume as in the input, despite the waveform chart on the front panel showing an amplitude five orders of magnitude less! can you help explain that to me? what can I do, will it matter coming out of the Blackfin and into an amplifier?
i appreciate any input anyone can give me on all this!! thank you!!

Hi noahgrant,
I've had a look at your vi and can make some suggestions that you can try.
From what I can see, your while loop with the wait timer of 100 ms and continue if true condition on it (we shall cool this loop 1) will always keep running.
The other while loop (loop 2) is nested within a couple of case structures and will only run once (false to a continue if true condition). The default case has a different condition and will always run, instead.
From what I can make of this, loop 2 and all its case structures will only run once (except for case 0, default). WHEN it runs will depend on how it was compiled on the Blackfin - case structure/loop2 may go first or loop 1 will go first.
If you want loop 2 to go first (and only go once) then you need to link the output of the case structure to the input of loop 1 - this can be done by simply wiring up a boolean to it (data flow rules).
If you want loop 2 to always be checking the status of the mode then you need to place the whole case structure within a while loop, to run continuously.
That is a very quick interpretation of what you are trying to do. There are a lot of question marks (missing vi's) and some heavy use of local variables. I would consider using sub-vi's, in particular functional global variables (FGV's).
I hope that helps.

You're mishandling the responses. You terminate if you don't get an "Ok" string, but that's not how success is defined - you should get a 200 code back, typically with an "OK" (not caps) message.
It doesn't help that you're ignoring all of the server output after each command, so you never find out if anything goes wrong.
You're also reinventing a wheel. The JavaMail API exists for this: http://java.sun.com/products/javamail/

My iPod touch shows that it is charging but it actually doesn't charge and I've tried to restore/ restart it but the only icon is the charging icon with the battery icon with a bit of red fill and a small lightning icon below it. Can anybody help me?

My iPod touch shows that it is charging but it actually doesn't charge and I've tried to restore/ restart it because the only icon is the charging icon, the one with the battery icon with a bit of red fill and a small lightning icon below it. Can anybody help me and give me solutions before I go to an apple service center?

Place the iPod Touch into DFU mode. This will be similer to what the factory would do to install the iOS onto new iOS devices.
Placing it into DFU mode will allow you to "format" and install the current iOS for that device.
To place your iOS device into DFU mode.
First connect you iOS device to you computer.
Open iTunes if not already open
Now turn off your iOS device using the power swipe.
Press the home and sleep button on your iOS device for 10 seconds.
Release the sleep button but carry on holding down the home button. For another 10 seconds.
Your iOS device should now be on DFU. Click on restore and iTunes will download the lastest iOS for your device.
Hopefully that sorts it if not, you will have to go to a sevice centre or call Apple Care up and get them to collect it and repair it. (replace it)

The phone was jailbroken. That's what that error indicates. You can't get help here. You can't get help from Apple.
Try Google.

I have purchased a ringtone in the iTunes Store for my iPad, and I cannot find the download together with my music. I have received the invoice but I have no product. I am working with iOS6, if that helps. Can anybody help me?

I am confused. Do you mean you found the music, not the tones, or you can't find either?
If the former, then this is normal. You can't redownload tones from the Cloud.

You are missing one or more photos - youprobably have a page background that requires a photo which is behind a page with photos on it - all pages must either have a photo or be a color - if you have a gray background it requires a photo - look through the book carefully and be sure to look at the background on any full page photos - you will find one or more missing photos

Update Server
Try:
- Powering off and then back on your router.
- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers
Public DNS — Google Developers
OpenDNS IP Addresses
- Try on another computer/network
- Wait if it is an Apple problem

See:
Recovering your iTunes library from your iPod or iOS device: Apple Support Communities
Basically you will have to transfer its contents to the new computer and then restore the iPod and then resync. An iPod can only sync to one iTunes library.
BTW you posted in the iPod touch forum.

Can anybody help me and find why that code cause that exception
