Hi,
My issue is resolved. I thought it may be helpful for others. So
posting the solution for the issue I was facing.
For the samplerate problem, we commented the code in frameworks/base/
libs/audioflinger/AudioHardwareInterface.cpp in
size_t AudioHardwareBase::getInputBufferSize(uint32_t sampleRate, int
format, int channelCount) function
/* if (sampleRate != 8000) {
LOGW("getInputBufferSize bad sampling rate: %d", sampleRate);
return 0;
}*/
Incase you don't have voicesearch.apk in your hardware you can get it
from net. I got it from this link http://www.chadhaney.com/droidXDefault/
You should also have GoogleServicesFramework.apk. you can download
from the above link
Also you need to download libspeech.so. You can get it in net.
Initially we were getting 'Connection problem' when we ran the
application. Even though we are connected to the network (using
ethernet).
Since Androidframework didnt have support for ethernet in the
connectivity framework, application is not able to connect to
internet.
So to add ethernet support we took the patches from following links:
https://review.source.android.com/#dashboard,1001873
https://review.source.android.com/#dashboard,1001874
If you have wifi or data connection you need not use the above
patches.
Thanks and Regards,
ksp
