can't find audio file after recording

Question

i created a voice recorder in android studio, but i cant find the recorded file on my phone. normally am meant to attach it to an email that will be sent, but i cant find it on my phone for me to add it as an attachment.This is my code written below

   private String outputFile = null;

   private MediaRecorder mRecorder;

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);


    outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.3gpp";
    }




     public void startRecording() throws Exception {



    if(mRecorder!=null){
        mRecorder.release();
    }

    File fileOut = new File(outputFile);

    if(fileOut!=null){
        fileOut.delete();
    }


    mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setOutputFile(outputFile);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);


        mRecorder.prepare();

    mRecorder.start();
}





public void stopRecording() {

    if(mRecorder != null) {
        mRecorder.stop();
        mRecorder.release();
    }
}

public void record(){



    new CountDownTimer(10000, 10000) { // 5000 = 5 sec

        public void onTick(long millisUntilFinished) {
            try {
                startRecording();
            } catch (Exception e) {
                e.printStackTrace();
            }
            Toast.makeText(HomeActivity.this, R.string.record_audio, Toast.LENGTH_LONG).show();
        }

        public void onFinish() {
            stopRecording();
            mProgressDialog.dismiss();
            Toast.makeText(HomeActivity.this, R.string.record_saved, Toast.LENGTH_LONG).show();
        }
    }.start();


}

If You develop in API23 and above, you have to request permissions at runtime. Also if your App is lower than API23 but runs on a device with API23 and above, you need to adjust your app and request that permissions because it´s possible that these permissions are not added automatically. — Opiatefuchs, Jun 21 '16 at 12:05
Two things: first, you are deleting a file that is not null? I guess you want to delete the file if it has been created before? So `if(fileOut.exists())` must be called instead of `if(fileOut!=null)` . Second: why you set this in a countdown timer? And where are you starting the timer? You are nowhere calling `record()` or `startRecording()` methods..... — Opiatefuchs, Jun 21 '16 at 13:58
I want it to record for only 10 seconds automatically, am using countdown timer to make it record for 10 seconds and stop recording after 10 seconds, am calling record from onclick of a button — Henry, Jun 21 '16 at 14:02
I think there must be any problem and a error is thrown. From the code I can´t see anything missing. Make a log and check your logcat output.... — Opiatefuchs, Jun 22 '16 at 05:39
Another possible issue is that your storage is not mounted. Be sure your storage is mounted with `Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);` — Opiatefuchs, Jun 22 '16 at 05:44
Also, I am not sure if equal startTime and interval are working correct. It´s a behaviour of the countdowntimer that onTick is never called, if the remaining time is lower than the interval. Please do the following test and set the startTime to `20000` and interval to `10000` like new `CountDwonTimer(20000,10000)` — Opiatefuchs, Jun 22 '16 at 05:52

It´s possible that your storage is not mounted. I faced especially on CyanogenMod systems that the sotrages are not mounted by default. Just be sure the storage is mounted by simply calling:

    boolean isMountend = Environment.getExternalStorageState().
equals(android.os.Environment.MEDIA_MOUNT‌ED);

They won't show up when you connect via cable to copy them over. You need to be connected via WiFi go in an open the recording on your phone then up top right tap on the options. There will be an option to upload it to Google Drive. Once it is uploaded to your account, download it to your desktop drive.
