Limit recording time (Mediarecorder)

Question

Hello, as the title says I want to limit the recording of my code:

    private void startRecording() {
    mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setOutputFile(mFileName);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

    try {
        mRecorder.prepare();
    } catch (IOException e) {
        Log.e(LOG_TAG, "prepare() failed");
    }

    mRecorder.start();
}

private void stopRecording() {
    mRecorder.stop();
    mRecorder.release();
    mRecorder = null;

    uploadAudio();
}

this is where I give the order to record

        mImageMic.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    startRecording();
                    mRelative.setVisibility(View.GONE);
                    mTextGravando.setVisibility(View.VISIBLE);
                    mTextGravando.setText("Gravando...");
                    mCronometro.setVisibility(View.VISIBLE);
                    //Parte Importante
                    mCronometro.setBase(SystemClock.elapsedRealtime());
                    mCronometro.start();

                    return true;
                case MotionEvent.ACTION_UP:
                    stopRecording();
                    mRelative.setVisibility(View.VISIBLE);
                    mTextGravando.setVisibility(View.GONE); 
                    mCronometro.setVisibility(View.GONE);
                    //Parte Importante                       
                    mCronometro.stop();
                    return true;
            }
            return false;
        }
    });

I thought of something like mCronometro is equal to 60000 milesegundos call the stop and the upload.

Just use the native method setMaxDuration of MediaRecorder when you set your object. In your case:

mRecorder.setMaxDuration(60000);

According to official documentation:

void setMaxDuration(int max_duration_ms) - the Maximum Duration (in ms) of the Recording Session. Call this after setOutFormat() but before prepare(). After Recording Reaches the specified Duration, a notification will be sent to the Mediarecorder.Oninfolistener with a "what" code of MEDIA_RECORDER_INFO_MAX_DURATION_REACHED and Recording will be stopped. Stopping Happens asynchronously, there is no Uarantee that the Recorder will have stopped by the time the Listener is notified.
