General :: WMP / MTP / Android Audio Format Detection

Mar 5, 2014

According to the MS website, Windows Media Player queries an MTP device to see what formats it supports. My Razr Maxx HD supports ogg and m4a. When attempting to sync WMP does not sync those files stating they might not be supported on the device. Being that I've had so much trouble in the past even getting any of the Android devices to be properly detected as an MTP device I'm worried this is a driver issue.I should be able to get WMP to at least convert them.

this is the device mis-reporting the formats, Windows not querying them properly, or an actual WMP issue? Would like to be able to get sync working without any conversions. Maybe there is a way to hardcode formats within the mtp inf file?

General :: SoundHound / Shazam - Inbuilt Audio Detection

Dec 14, 2012

I was wondering if there is anyway to make SoundHound or Shazam to detect musics that played from Internet radio, ie "tunein" or alikes, that usually plays only if you plug your headphones in?

It seems SoundHound and Shazam can only detect incoming sound using the phones mic, so if nothing is going to mic it will not detect anything at all.

I saw in a post from a Sony Xperia user that he accidently made it working but i think its only for that particular phone.

Any workarounds/mods to make this work on any android device?

Android :: How To Record Audio From Mic In Raw Pcm Format Into A Buffer Using Native Libraries Directly

Oct 9, 2009

My application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.

I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time.

I used the following values to create the AudioRecord..


It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck.

And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate.

Has anybody tried to access this native code?

HTC Incredible :: No Video Only Audio (MP4 File Format)

Jun 24, 2010

The HTC web site claims support for .mp4 and .wmv playback but I have had no luck. I have used various programs from HandBrake to Sony and I can get audio with no video (mp4). I can get audio with still image video (wmv). The DI seems very picky as to which videos it will actually play back. Is there a recommended way to convert my videos / DVS into a format the DI can play?

Android :: Wrong Format From String.format

Sep 6, 2010

Passing two int values m =0 & s = 11, to below function String formatted = String.format("%1$02d:%2$02d", m, s); returning the value like .0:11 ,What could be the problem? m=0, s=11 -->.0:11 m=0, s=1 --> .0:.1. The 0 added to format the string always coming as '.' (dot). Can anyone know ,from where the number patterns are getting loaded in Android? I gone thorough the code, Its related the following file, androiddalviklibcoreicusrcmainjavacomibmicu4jniutil ->localeData.numberPattern. How the pattern for particular locale is loaded, What could be the problem for the above?

Android :: Sobel Edge Detection

May 30, 2010

As part of an application that I'm developing for Android I'd like to show the user an edge-detected version of an image they have taken (something similar to the example below).To achieve this I've been looking at the Sobel operator and how to implement it in Java. However, many of the examples that I've found make use of objects and methods found in AWT (like this example) that isn't part of Android.My question is then really, does Android provide any alternatives to the features of AWT that have been used in the above example? If we were to rewrite that example just using the libraries built into Android, how would we go about it?

Android :: Accelerometer False Detection

I have a code snippet to detect accelerometer movements. It works some times by properly detecting slight movements, but sometimes it detects movements when I kept my device idle too. Are there any problems with built-in accelerometer detection on Android?

I use an HTC G-1 device. My code snippet is below. How do I resolve it so I can detect small device movements but not detect anything when the device is idle?

Android :: Face Detection In Phone

Nov 8, 2010

I am currently working on an experimental camera app. I'm looking into implementing face detection at the moment and am currently weighing up my options.I have considered the OpenCV port available for android and using their face detection functions, but from demos I have seen of previous implementations the camera seems to lag a lot.Considering the camera on the HTC desire has face detecting, I know it must be possible to get at least a semi decent face detection system in place. I was just wondering if anyone had an opinion on how I could get the best results.Using an available library? Implementing a particular algorithm myself?
