Simple Audio recorder app in Sketchware

1.  Switch on AppCompat and Design.

2. In main.xml, add two Buttons startBtn and stopBtn, and add two TextViews textview_message and textview_file.

3. Add a SpeechToText component (To add record audio permissions).

4. Add a String variable outputFile and add a custom variable of type MediaRecorder with name mediaRecorder.

5. In onCreate, add write string__to file path__ block (To add read and write external storage permissions). Then put following codes to define outputFile.

stopBtn.setEnabled(false);
File downloadsDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
String fileName = "recording_" + System.currentTimeMillis() + ".3gp";
File file = new File(downloadsDir, fileName);
outputFile = file.getAbsolutePath();

6. Create a More block startRecording and put following codes in it.

        try {
            mediaRecorder = new MediaRecorder();
            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
            mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
            mediaRecorder.setOutputFile(outputFile);
            mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
            mediaRecorder.prepare();
            mediaRecorder.start();

            startBtn.setEnabled(false);
            stopBtn.setEnabled(true);

            textview_message.setText("Recording Started");
        } catch (IOException e) {
            textview_message.setText(e.toString());
}

7. Create another More block stopRecording and put following codes in it.

if (mediaRecorder != null) {
            mediaRecorder.stop();
            mediaRecorder.release();
            mediaRecorder = null;

            startBtn.setEnabled(true);
            stopBtn.setEnabled(false);
            textview_message.setText("Recording Stopped");
        }

8. In startBtn onClick event, use more block startRecording.

9. In stopBtn onClick event use more block stopRecording.

10. Save and run the project.
