Android Studio Recording Media

Recording media in Android Studio refers to the functionality of capturing and storing audio and video data using camera and microphone components. This feature enables developers to build video conferencing, video recording, and live streaming applications seamlessly.

Syntax

The syntax for recording media in Android Studio is as follows:

MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
recorder.setOutputFile("path_to_output_file");
recorder.prepare();
recorder.start();

Example

The following code demonstrates how to record audio and video in Android Studio:

private MediaRecorder recorder;

private void startRecording() {
    recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
    recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
    recorder.setOutputFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/myvideo.mp4");
    try {
        recorder.prepare();
    } catch (IOException e) {
        e.printStackTrace();
    }
    recorder.start();
}

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

Output

The output of the above code is an MP4 file, which can be played using a video player.
