Description: Learn how to implement audio recording functionality in your Android application using the MediaRecorder class, providing users with a simple and effective way to capture audio.

Here is a basic example of how to record audio in an Android application:

// Request necessary permissions in AndroidManifest.xml // Activity code public class MainActivity extends AppCompatActivity { private MediaRecorder mediaRecorder; private String fileName; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); fileName = getExternalFilesDir(Environment.DIRECTORY_MUSIC).getAbsolutePath() + "/audiorecordtest.3gp"; mediaRecorder = new MediaRecorder(); } private void startRecording() { mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); mediaRecorder.setOutputFile(fileName); try { mediaRecorder.prepare(); mediaRecorder.start(); } catch (IOException e) { e.printStackTrace(); } } private void stopRecording() { mediaRecorder.stop(); mediaRecorder.release(); mediaRecorder = null; } }

Make sure to handle runtime permissions for Android 6.0 (API level 23) and higher. You can check for permissions and request them as needed to ensure your app works smoothly on all devices.
