Can the Android emulator record and play back audio using pc hardware?

Related searches

I don't have an android phone, but i'm trying to develop for it anyway. The only way to test my application at the moment is to use the emulator, which I've read does not support audio recording. However, I read about the startup command "-audio " which allows audio input/output from your pc using the 'winaudio' backend. I haven't been able to get it to work though, is it possible to record using my pc's microphone? If so, what am I doing wrong?

Recording audio is possible at least in the standard 2.3.3 emulator on Windows 7; I have tried it and it works. However, the recorded audio did sound a bit weird (slow) in my case. I did not investigate the cause.

You need to add audio recording + playback support to the emulator (Android SDK and AVD manager -> Virtual devices -> Edit -> Hardware -> New). Then use the [MediaRecorder API][1] to record (MediaRecorder.AudioSource.MIC).

Code is:

fMediaRecorder= new MediaRecorder();
fMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
fMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
fMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

fMediaRecorder.setAudioChannels(1);
fMediaRecorder.setAudioSamplingRate(8000);

fMediaRecorder.setOutputFile(fTmpFile.getAbsolutePath());

fMediaRecorder.prepare();

fMediaRecorder.start();

You also need

<uses-permission android:name="android.permission.RECORD_AUDIO"/> 

in your AndroidManifest.xml

Works for me, but Audio IS distorted.

  • will you please upload some source code that works on Windows7 to record the sound in android emulator ?? I really need it.
  • Ok Thanks for your reply. I have done with my own. And its work on 1.6 also.
  • I've used the 2.3.3 emulator never got this to work. But it works fine on the device. Keep your fingers crossed.
  • The built in speech recorder app also crashes in my emulator. Does that mean recording will not work on my machine?
  • After working for a long while on iOS, I had forgotten about this menu. I went back to Android and began having trouble with Speech Recognition and just thought that Android had suspended audio recording support newer OS versions of the emulators. Thanks a lot!
  • I'm on windows, I just read that building the source code is only possible on OSX and linux. Is this correct? Is there any other way?
  • I think thats correct. Also:for Froyo and less, you need 32-bit linux; for gingerbread and above, you need 64-bit linux. I am not aware of any other way...
