What is Media?

In the context of Android development, media refers to any kind of audio, video, or image content that can be played, recorded, or displayed on an Android device. Media is a crucial aspect of modern applications, providing rich user experiences through multimedia.

Types of Media in Android

Android supports various types of media, including:

Audio (MP3, WAV, AAC)
Video (MP4, 3GP, MKV)
Images (JPG, PNG, GIF)

Playing Audio

To play audio in Android, you can use the MediaPlayer class. Here's a basic example:

MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.sample_audio);

                mediaPlayer.start();

Make sure to include your audio file in the res/raw directory of your project.

Playing Video

Playing video in Android can be done using the VideoView class. Here's how you can do it:

<VideoView

                    android:id="@+id/videoView"

                    android:layout_width="match_parent"

                    android:layout_height="wrap_content" />

In your activity:

VideoView videoView = findViewById(R.id.videoView);

                Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.sample_video);

                videoView.setVideoURI(uri);

                videoView.start();

Displaying Images

Displaying images in Android can be achieved using the ImageView class. Here's an example:

<ImageView

                    android:id="@+id/imageView"

                    android:layout_width="wrap_content"

                    android:layout_height="wrap_content"

                    android:src="@drawable/sample_image" />

Recording Audio

To record audio in Android, you can use the MediaRecorder class. Here's a simple example:

MediaRecorder recorder = new MediaRecorder();

                recorder.setAudioSource(MediaRecorder.AudioSource.MIC);

                recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);

                recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

                recorder.setOutputFile("/path/to/output.3gp");

                recorder.prepare();

                recorder.start();

Don't forget to request the necessary permissions in your AndroidManifest.xml and at runtime:

<uses-permission android:name="android.permission.RECORD_AUDIO" />

                <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Recording Video

To record video, you can use the MediaRecorder combined with the device's camera. Here's a basic setup:

MediaRecorder recorder = new MediaRecorder();

                Camera camera = Camera.open();

                camera.unlock();

                recorder.setCamera(camera);

                recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);

                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.mp4");

                recorder.prepare();

                recorder.start();

Make sure to handle the necessary permissions and camera setup.
