    copied!<p>Hej, im currently trying to get AudioRecord to work. Because I need it in a bigger project. But it seems to mess up a lot. I have been trying alot of things, so I went back to basic when I traced this bug. I am using my Samsung Galaxy S as my debugdevice.</p> <p>My problem is, first time after a reboot of my device I can initialize the AudioRecord object I create without problems. But the second time I run it, it won't initialize the AudioRecord object. I have tried several frequencies, fyi. </p> <p>Here is my code: </p> <pre><code>package android.audiorecordtest; import android.app.Activity; import android.media.AudioFormat; import android.media.AudioRecord; import android.media.MediaRecorder; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class AudioRecordTest extends Activity { int frequency; AudioRecord audRec; TextView txtVw; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); txtVw = (TextView) findViewById(R.id.txtVw); frequency=8000; int bufferSize=(AudioRecord.getMinBufferSize(frequency, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT))*2; if (bufferSize&gt;0) { audRec = new AudioRecord(MediaRecorder.AudioSource.MIC, frequency, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT, bufferSize); int status = audRec.getState(); if (status == AudioRecord.STATE_INITIALIZED) { txtVw.setText("Initialized" + frequency); } else { txtVw.setText("Not Initialized i=" + frequency); } } </code></pre> <p>After a few hours of looking through logcat information i found this event</p> <pre><code> 02-28 10:46:37.048: DEBUG/dalvikvm(4477): GC_EXPLICIT freed 1801 objects / 98944 bytes in 97ms 02-28 10:46:37.048: VERBOSE/AudioRecord(4477): stop </code></pre> <p>Which seems to "release the native hold on the AudioRecord. So i tried doing an override of finalize with my Audiorecord object.release(). This didnt work though.. Anyone have any idea?</p>
