Re: [android-developers] Re: AudioRecord.getMinBufferSize hangs on KitKat
Update: Sometimes the call to: AudioRecord.getMinBufferSize(22050, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); will succeed only to hang when you go to create the AudioRecord object: new AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, totalBytes); Subsequently Shazam wont work and Google Now voice recording stops working...

[android-developers] Any problem with the HTC Inspire??
Hi Guys
Ive tested the hell out of my app, Tunepal on many different devices
and its sold about 1000 copies. Ive tested it successfully on
everything from a Samsung Galaxy Europa up to a HTC Desire HD and no
problems so far.
Over the last couple of days however I've been receiving reports from
owners of the HTC Inspire to say that the app crashes on startup. Ive
gotten users to submit crash reports and this is what shows up:
java.lang.RuntimeException: Unable to start activity
ComponentInfo{org.tunepal/org.tunepal.Tunepal}:
java.lang.RuntimeException: Unable to start activity
ComponentInfo{org.tunepal/org.tunepal.MyTunesActivity}:
android.database.sqlite.SQLiteException: no such table: tuneindex: ,

at android.app.ActivityThread$H.handleMessage(ActivityThread.java:

...
...
...
Basically I have a sqlite database that ships with the app thats
prepopulated. This has been working successfully on devices for the
past year, however on the HTC Inspire I get the exception
Apparently you cant install non-makret apps on these devices (so one
of my users told me anyway), so I cant even send them versions of my
app to test different things.
Just wondering if there is anything strange/wierd about these devices?
Anyone else having problems running their apps on the HTC Inspire?
Bryan

Over the next few weeks, we’ll be adding paid apps support for additional countries. If you have selected to publish your paid apps to all locations and intend to support all new locations as we expand the number of supported countries for paid apps, you don’t have to do anything. If you have selected to publish your paid apps to all locations but intend to only target the currently supported 14 countries, please update your location selections to target these specific countries. Please look for follow-up emails when we introduce paid apps support for specific additional countries in the coming weeks. At that time, you’ll have the option to target these specific countries. Thanks, and we look forward to continue working with you on Android Market. Sincerely, The Android Market Team It seems at last Google are adding new coutries for paid apps!

[android-developers] Re: Record audio problem on the LG Ally
Jeff I did some benchmarking first. I have versions of my algorithms in both C++ and Java. I sample at 22KHz for 12 seconds and perform an SFTF on 2048 sample frames with a 75% overlap in order to transcribe what the user has played on their instrument. I do some other stuff on the spectrum to figure out the F0 and I have a mechanism for filtering out some of the transcribed notes that I've described in my papers: http://www.comp.dit.ie/bduggan/research.php C++ code to do this on the iPhone 3G takes about 12 seconds to do the DSP. This is about 50% faster on an iPhone 4G 100% Java code to do the identical task on a 1Ghz HTC Desire takes minutes (running Android 2.1). I dont have the exact numbers, but basically not practical. The same code running on WIndows 7, JDK takes a few seconds. The identical C++ implementation I use on the iPhone I call on Android using the Android NDK and it only takes a few secomds Conclusion - Android Java on 2.1 is slow for maths intensive code. DSP in Java on Android 2.1 or less is not practical. It has to be done in native code. Thats why Im a bit reluctant to consider a Win Phone 7 version of my app - no native code. Hope that helps!

[android-developers] Re: Record audio problem on the LG Ally
I solved it I am pleased to report and my app now works on all Android
phones Nexus One's LG's, HTC etc:
At last I can answer a question on this forum instead of just posting
them :-) The solution it seems is to request chunks of data from the
record device of size minBufferSize which you get using this code:
static
{
minBufferSize = AudioRecord.getMinBufferSize(sampleRate,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
buffer = new byte[minBufferSize];
}
If there isnt minBufferSize bytes left, then you have to request the
amount thats left to read. See how I calculate toRead below.
bufferReadResult will return exactly how many bytes were read and this
is what you use to advance your global buffer counter. Interestingly,
minBufferSize varies quite a bit on the phones I have tested. I copy
the 16 bit PCM audio data into an array of floats as I perform DSP on
the buffer at a later stage (in C++). If anyone is interested in how I
do this let me know and I'd be happy to explain. Here is the full code
for my Record AyncTask class. If anything is not clear, let me know:

[android-developers] Re: Record audio problem on the LG Ally
Giampaolo
Thanks for yoru reply, but that's definitely not the problem. In fact
what you suggest is what I already do. doInBackground is only called
once and System.gc gets called once before the recording starts. The
call audioRecord.read blocks until the appropriate number of bytes is
read. Ive tried this as an alternative:
buffer = new byte[bufferSize];
int startAt = 0;
int minBufferSize =
AudioRecord.getMinBufferSize(sampleRate,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
audioRecord = new
AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize);
audioRecord.startRecording();
int bufferReadResult = 0;
while (startAt < bufferSize)
{
int toRead = 0;
if (startAt + minBufferSize >= bufferSize)
{
toRead = bufferSize - startAt;
}
else
{
toRead = minBufferSize;
}
System.out.println("Starting at " + startAt + "
reading " + toRead + " bytes");
bufferReadResult = audioRecord.read(buffer, startAt,
toRead);
System.out.println("Read " + bufferReadResult + "
bytes");
if (bufferReadResult ==
AudioRecord.ERROR_INVALID_OPERATION)
{
message = "ERROR_INVALID_OPERATION returned";
error = true;
break;
}
if (bufferReadResult == AudioRecord.ERROR_BAD_VALUE)
{
message = "ERROR_BAD_VALUE returned";
error = true;
break;
}
if (bufferReadResult != toRead)
{
message = "Requested " + toRead + " bytes but read
" + bufferReadResult + " bytes";
error = true;
}
startAt += bufferReadResult;
}
This works fine (as does the previous code) on my HTC desire. I'm
waiting for some feedback from my Lg Ally user to let me know if it
works on his phone. If so, problem solved. If not, I'll remove the
lines:
if (bufferReadResult != toRead)
{
message = "Requested " + toRead + " bytes but read
" + bufferReadResult + " bytes";
error = true;
}
And see if that works. Not all Android phones work the same it would
appear.

A complete waste of my time, but what can ya do? >From Reto Meier: "Unfortunately I can't give you a time-frame for paid app buyer or seller support for Ireland either. The team working on that side of things have a lot on their plates so getting even a rough estimate for any specific country is near impossible." Interesting that Apple, Microsoft, Paypal, Nokia etc can manage this but Google can't even give me date when it might be available. Not very professional. :-( Bryan On Jul 27, 7:39 pm, Anton Persson wrote: > That, and the ability for folks to actually access the paid-for apps... > > Sweden, like probably many countries still, have no access to the paid > apps...

[android-developers] Record audio problem on the LG Ally
Hi guys
I have a music recognition app (Tunepal) that records 12 seconds of
audio @ 22KHz (in one second chunks). After each second, the audio is
copied from a byte array into a float array and eventually I perform
some DSP on the float array.
My app is available on the Android Marketplace and is selling ok. I
have tested it on lots of different phones, such as the HTC Desire/
Hero/Motorola Droid etc and everything is fine.
One of my users has an Lg Ally (running Android 2.1 I believe) and the
recording is not working. In fact it's crashing the app. I have
developed a test program that just records some audio and I think I
have isolated the problem. The test program records audio of various
durations and sample rates and then plays it back. This is the crucial
bit of code:
protected Void doInBackground(Void... arg0)
{
System.out.println("Recording started");
audioRecord = null;
System.gc();
int totalBytes = bufferSize;
try
{
buffer = new byte[bufferSize];
audioRecord = new
AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, totalBytes);
audioRecord.startRecording();
int bufferReadResult = audioRecord.read(buffer, 0,
bufferSize);
if (bufferReadResult ==
AudioRecord.ERROR_INVALID_OPERATION)
{
message = "ERROR_INVALID_OPERATION returned";
error = true;
}
if (bufferReadResult == AudioRecord. ERROR_BAD_VALUE)
{
message = "ERROR_BAD_VALUE returned";
error = true;
}
if (bufferReadResult != bufferSize)
{
message = "Requested " + bufferSize + " bytes but read
" + bufferReadResult + " bytes";
error = true;
}
}
catch (Exception e)
{
message = e.getMessage();
error = true;
}
if (! isCancelled())
{
doneRecording();
}
return null;
}
This code works fine on my HTC Desire, but on the LG Ally, no matter
what the buffer size or sample rate is set to, bufferReadResult always
returns 2048. In other words, the call to:
audioRecord.read(buffer, 0, bufferSize);
Always reads just 1024 samples of audio. Actually I havent tested to
see if the buffer contains anything useful.
I can possibly get around this in my app with a bit of work, but I was
wondering if anyone else has encountered this problem and if there is
a better way to get around it than reading the audio in 2K chunks.
You can try out the test app for yourself here:
http://tunepal.org/tunepal/android/RecordTest.apk
Rotations will screw it up BTW, so keep your phone orientated in
portrait for the test.

[android-developers] Re: Android paid apps in Ireland
Hi Shane I took a look at ZappMarket. A couple of suggestions. The URL http://zappmarket.com/ just shows the zapp market logo and nothing else after that. When I went to upload application I got the message "We have detected that you are using Internet Explorer" even though I am using Firefox What are your commissions? How does a user get the APK onto their machine? How does a user get updates to their app? Have you any features to prevent app piracy? Thanks for the information and best of luck with ZappMarket!

[android-developers] Re: How to dismiss the soft keyboard
Thanks!
I used:
txtQuery.setOnKeyListener(this);
...
...
public boolean onKey(View arg0, int keyCode, KeyEvent event)
{
if ((event.getAction() == KeyEvent.ACTION_UP) && (keyCode ==
KeyEvent.KEYCODE_ENTER))
{
doSearch();
...
...
And used the answer from the previous post to hide the keyboard

[android-developers] How to dismiss the soft keyboard
Hi I have a TextView and a search button on an activity. When I press the enter key, I want to do something and then dismiss the soft keyboard programatically. I have set the TextView to be single line by using: android:singleLine="true", which moves the focus to the next component when you press the enter key 1. How do I trap the enter key? A TextWatcher? An OnKeyListener? 2. How do I dismiss the soft keyboard programatically? Thanks! Bryan -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Android paid apps in Ireland
Hi guys I have a popular music search engine app for the iPhone called Tunepal (http://www.youtube.com/watch?v=Gr0xnlYZ_gM) and in response to multiple requests I have been working hard to port it Android. The port will be finished in the coming weeks and I want to sell it on the Android Marketplace. The majority of my iPhone users are in Ireland (though I have users in 22 countries). I am not going to release it for free. It seems I cant sign up for a google checkout merchant account, because I live in Ireland and there are no paid apps allowed on the Irish Android Marketplace!!! The first problem I can get around by using my sisters bank account in London (why??) but how do I get around the second problem? 1. When will the Android paid app marketplace be available in Ireland 2. If its not going to be for a while, how do I sell my app in Ireland withough using the Android Marketplace?
