Android AudioRecord - Won't Initialize 2nd time

Question

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. 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. Here is my 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…

Accepted Answer

I was able to reproduce your problem (on a Samsung phone). I added an onDestroy() method releasing the record:

```
@Override
public void onDestroy() { 
    super.onDestroy();
    System.out.println("OnDestroy");
    audRec.release();
}
```

After adding this, the audioRecord seems to initialize correctly every time the activity is started.
