title: MediaRecorder crashes on start
body: <p>i've searched many topics but no straight answer.</p>
  
  <p>I have this code :</p>
  
  <pre><code>        recorder = new MediaRecorder();
      recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
      recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
  
      recorder.setOutputFile(mFileName);
      recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
      if(!mStartRecording)
      {
          btn.setText("Stop Recording");
          try {
              recorder.prepare();
  
          }  catch (IOException e) {
              e.printStackTrace();
          }
          recorder.start();
          mStartRecording = true;
      }
      else
      {
          btn.setText("Start Recording");
          mStartRecording = false;
          recorder.stop();
          recorder.reset();
          recorder.release();
  
          recorder = null;
      }
  </code></pre>
  
  <p>And i've added :</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;
  &lt;uses-permission android:name="android.permission.STORAGE" /&gt; 
  &lt;uses-permission android:name="android.permission.RECORD_AUDIO" /&gt;
  </code></pre>
  
  <p>(saw somewhere that adding STORAGE solved it, no good for me)</p>
  
  <p>I'm developing on API Level 7 (Android 2.1)</p>
  
  <p>stack trace says "start faild"
