I already know the frequency for the carrier signal and all the technology around gps. The question i have: Is it somehow possible to get the received frequency of the signal? I am asking, because i want to derive some functions from doppler navigation for which i need the received frequency of the gps signal, in order to compare it with the carrier frequency. I know, that this is very hardware related, are there any possibilities to grab the information i want to?

Android :: AudioRecord On Emulator With Frequency 8 KHz

Mar 25, 2010

I'm doing a voice recording using AudioRecord class and the main requirement that the frequency must be 16000 Hz. I'm using only emulator in development process for now and met the problem that I can't set frequency more than 8000, otherwise I get bufferSize -2, and can't create instance of AudioRecord with such buffer. Thank you to Szabolcs Vrbos, he told me that this problem is only with emulator and several Samsung phones, device can record with higher frequency.I need a word from Android engineers that I will be able to record voice with 16000 Hz frequency on for instance HTC Hero (Android 1.5)or similar device with os 1.5 or higher.

Pop-up Texts At Set Time Frequency

Nov 1, 2012

So, I want an app where I store different texts, which then later pops up when I want, like every 24hr or every morning. I would like to make this app myself because I want it simple and to understand it completely.

I am not new to programming, but I don't know this language. Do you think this would be hard for me, to create this app, but with "full guidance", .

Android :: Guitar Tuner - No Public API For Frequency Analysis

Oct 17, 2010

I am looking for some help. I'm new to android, and java development. I've got a pretty good handle on the basics, but I'm having an issue figuring out some more advanced operations. I'm working a guitar tuner, which is a stepping stone to a chromatic piano tuner. There is no public API for frequency analysis, so I'm thinking I need to write into code a Fast Fourier Transform, and I'll assume I need to import a different package for this. Once I display the frequency of any given note, I need it to reference it's offset to a pre-measured Mhz. There is alot to write, I'm aware, but my first step is to try to figure out HOW to get the frequency, and display it in the UI.

Android :: Possible With Droid / Java To Change Frequency Of A Soundfile?

Sep 17, 2010

I try to change the frequency of a single soundfile. I managed to do that in android with the SoundPool thing. But the result sounds really bad.
So I stepped about the Fourier Transformation - but I am not sure if this is what I am looking for.

I want to load a single file and change the frequency of that file every time that file is played. So I can create melodies out of one tone. Is that possible with android/java?

General :: Can Change UMTS / WCDMA Frequency On Android?

Aug 23, 2013

Mobileuncle shows that my device is only on WCDMA 2000 with other frequencies grayed out...particularly WCDMA 850 which the one I want to access to get HSPA, right now only getting 2G.

It might be just a APN problem even though I've changed the APN several times with no results, so I'm wondering about changing the Frequency of the WCDMA, or accessing all frequencies?

General :: Unable To Scale CPU Frequency On Phone

Feb 3, 2013

I have a ROOTED chinese brand phone with the MTk6575 CPU (1 GHZ) with android 2.3.6 installed on it, and am trying to improve the phone's battery life by scaling down the CPU frequency. But out of all the apps I have tried (SetCPU, No-Frills, Android Overclock) none of them is able to read the CPU Governor or current CPU frequency. My question is could we change this frequency directly by editing any of the files inside the /system folder or is there any other security setting that prevents these apps from reading or changing the CPU frequencies?

General :: 3G Frequency Of Phone Is Hardware Or Firmware Dependent?

Dec 2, 2012

I am asking this because recently bought a BLU VIVO D910a phone from U.S., it has Android 4.0 firmware and its 3G Network is HSDPA 850 / 1900.

I made a big mistake, because the country where I currently live and work (Montenegro) uses 2100 3G network. I shoud have ordered the international version of BLU Vivo, the D910i which has HSDPA 850 / 2100. So, currently I cannot make use of the 3G data capability of my new phone

My question is: if I get the firmware (or just the modem.bin) of D910i and flash it to my phone will I change by this way the 3G frequency or it is hardware-dependent?
