    <p>I want to record voice as long as holding the record button and save that voice into the raw folder in my project. I used the code below. Altough there appears no errors, i couldn't get any output. What can be the problem ? Do you have any suggestions? Thanks,</p> <pre><code>public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub Runnable mAction = new Runnable() { public void run() { System.out.println("Performing action..."); int frequency=11025; int channelConfiguration=AudioFormat.CHANNEL_CONFIGURATION_MONO; int audioEncoding= AudioFormat.ENCODING_PCM_16BIT; File file=new File(Environment.getExternalStorageDirectory(),"raw.pcm"); try{ file.createNewFile(); }catch(IOException e){} try{ OutputStream os=new FileOutputStream(file); BufferedOutputStream bos=new BufferedOutputStream(os); DataOutputStream dos=new DataOutputStream(bos); int bufferSize=AudioRecord.getMinBufferSize(frequency, channelConfiguration, audioEncoding); short[] buffer=new short[bufferSize]; audioRecorder=new AudioRecord(MediaRecorder.AudioSource.MIC, frequency, channelConfiguration, audioEncoding, bufferSize); audioRecorder.startRecording(); isRecording=true; while(isRecording){ int bufferReadResult=audioRecorder.read(buffer, 0,bufferSize); for(int i=0;i&lt;bufferReadResult;i++){ dos.writeShort(buffer[i]); } } audioRecorder.stop(); dos.close(); }catch(Throwable t){} } }; switch(event.getAction()) { case MotionEvent.ACTION_DOWN: if (myHandler != null) return true; myHandler = new Handler(); myHandler.postDelayed(mAction, 500); break; case MotionEvent.ACTION_UP: if (myHandler == null) return true; isRecording=false; myHandler.removeCallbacks(mAction); myHandler = null; break; } return false; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
