}
private void startRecording() {
    recorder = new MediaRecorder();

    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setOutputFormat(output_formats[currentFormat]);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    recorder.setOutputFile(getFilename());

    //recorder.setOnErrorListener(errorListener);
    //recorder.setOnInfoListener(infoListener);

    try {

            stopRecording();

            break;
        }

        case R.id.button3: { 
            Toast.makeText(call1.this, "Playing Audio", Toast.LENGTH_SHORT)

Can you do this?

File file = new File(getFilesDir()+ "/somefolder");

Always remember to get the permissions added in the manifest file!
