Invoking audio recorder and getting the resulting file

Question

I am trying to invoke the audio recorder on Android 2.2.1 (device Samsung Galaxy POP) using the following code:

private static final int ACTIVITY_RECORD_SOUND = 1;
Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
startActivityForResult(intent, ACTIVITY_RECORD_SOUND);

This invokes the recorder successfully. In my activity result i do the following:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK) {
        switch (requestCode) {
                         case ACTIVITY_RECORD_SOUND:
                             data.getDataString();
                         break;
                            }
                }
       }

After i complete the recording i press back on the audio recorder which returns the control to the onActivityResult method as expected, but my resultCode is always 0 (which is Activity.RESULT_CANCELED) and my data is null. Am i missing out on something here? Kindly help me with this. This works on the emulator but not on the device. Thanks in advance.

the audio recorder should offer you to actually use the record you made, which is when it should be returned to the onActivityResult. — njzk2, Sep 16 '13 at 09:00

This works for me:

   @Override protected void onActivityResult(int requestCode, int resultCode, Intent data)
   {
      switch(requestCode) {
         case Flashum.TAKE_MUSIC:
         case Flashum.TAKE_VOICE:
            if (resultCode == Activity.RESULT_OK)
            {
               Log.i(Flashum.LOG_TAG, "onActivityResult got new music");
               Bundle extras = data.getExtras();
               try {
                  Uri u = data.getData();
                  String imageUri;
                  try {
                     imageUri = getRealPathFromURI(u);
                  } catch (Exception ex) {
                     imageUri = u.getPath();
                  }
                  File file = new File(imageUri);
                  FragmentFlash fragmentFlash = (FragmentFlash)mTabsAdapter.getFragment("flash");
                  if (fragmentFlash != null)
                     fragmentFlash.gotMusic(file.getPath());
               } catch (Exception ex) {
                  String s = ex.toString();
                  Log.i(Flashum.LOG_TAG, "onActivityResult " + s);
               }
            }
            else
            {
               Log.i(Flashum.LOG_TAG, "onActivityResult Failed to get music");
            }
            break;
      }
   }

   public String getRealPathFromURI(Uri contentUri) {
      String[] proj = { MediaStore.Images.Media.DATA };
      Cursor cursor = managedQuery(contentUri, proj, null, null, null);
      int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
      cursor.moveToFirst();
      return cursor.getString(column_index);
   }

I finally found a workaround for my problem by using the FileObserver. I achieved it by doing the following:

package com.pravaa.audiointent;

 import java.io.DataOutputStream;
 import java.io.File;
 import java.io.FileInputStream;
 import java.io.FileNotFoundException;
 import java.io.FileOutputStream;
 import java.io.IOException;
 import java.util.Enumeration;
 import java.util.Vector;

 import android.app.Activity;
 import android.content.Intent;
 import android.os.Bundle;
 import android.os.FileObserver;
 import android.provider.MediaStore;
 import android.view.View;
 import android.view.View.OnClickListener;
 import android.widget.Button;
 import android.widget.LinearLayout;
 import android.widget.Toast;

public class AudioActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
private Button sampleButton;
private FileObserver mFileObserver;
private Vector<String> audioFileNames;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    audioFileNames = new Vector<String>();
    LinearLayout finalContainer = new LinearLayout(this);
    sampleButton = new Button(this);
    sampleButton.setOnClickListener(this);
    sampleButton.setText("Start Audio Intent");
    finalContainer.addView(sampleButton);
    setContentView(finalContainer);
    addObserver();

}

private void addObserver() {
    this.mFileObserver = new FileObserver("/sdcard/Sounds/") {
        @Override
        public void onEvent(int event, String path) {
            if (event == FileObserver.CREATE) {
                if (path != null) {
                    int index = path.indexOf("tmp");
                    String tempFileName = (String) path.subSequence(0,
                            index - 1);
                    audioFileNames.add(tempFileName);

                }
            } else if (event == FileObserver.DELETE) {
                if (path != null) {
                    int index = path.indexOf("tmp");
                    String tempFileName = (String) path.subSequence(0,
                            index - 1);
                    if (audioFileNames.contains(tempFileName)) {
                        audioFileNames.remove(tempFileName);
                    }
                }

            }
        }
    };
}

private void readFile(String fileName) {

    File attachment = new File("/sdcard/Sounds/" + fileName);
    if (attachment.exists()) {
        FileInputStream fis;
        try {
            fis = new FileInputStream(attachment);
            byte[] bytes = new byte[(int) attachment.length()];
            try {
                fis.read(bytes);
                fis.close();

                attachment.delete();

                saveMedia("Test" + fileName, bytes);

            } catch (IOException e) {

    }
}}

i was facing the same issue.. So instead of using an intent, I used the MediaRecorder class and its associated methods like setAudioEncoder, setAudioSource, prepare, start, stop, setOutputFormat and setOutputFile..It works fine now..

I also agree with the best answer so far (voted by question-owner), but it cannot read the file as it is a different path. my suggestion is to store the filename as a member-variable and call getFilename() only once.

There is a known issue with Galaxy Android devices where result intents are null where you would expect them to contain a photo. This might also apply here. See http://kevinpotgieter.wordpress.com/2011/03/30/null-intent-passed-back-on-samsung-galaxy-tab/.

One way to solve this, is to add

intent.putExtra(MediaStore.EXTRA_OUTPUT, someFileUri);

to your intent, explicitly telling the target app where to store the resulting file.

Check out this example if you need help creating a good file Uri.

did you try this? because I tried it here and it doesn't appear to have an effect. I think EXTRA_OUTPUT is ignored for audio recordings, it has an effect only for picture taking and video recording. But I may be wrong. – Emmanuel Touzery Jun 26 '12 at 09:04
@EmmanuelTouzery You are not. That's exactly what is stated in documentation: http://developer.android.com/reference/android/provider/MediaStore.html#EXTRA_OUTPUT – Pijusn Jul 06 '13 at 11:38
